How to Write a Conclusion for Research Papers (with Examples)

The conclusion of a research paper is a crucial section that plays a significant role in the overall impact and effectiveness of your research paper. However, this is also the section that typically receives less attention compared to the introduction and the body of the paper. The conclusion serves to provide a concise summary of the key findings, their significance, their implications, and a sense of closure to the study. Discussing how can the findings be applied in real-world scenarios or inform policy, practice, or decision-making is especially valuable to practitioners and policymakers. The research paper conclusion also provides researchers with clear insights and valuable information for their own work, which they can then build on and contribute to the advancement of knowledge in the field.

The research paper conclusion should explain the significance of your findings within the broader context of your field. It restates how your results contribute to the existing body of knowledge and whether they confirm or challenge existing theories or hypotheses. Also, by identifying unanswered questions or areas requiring further investigation, your awareness of the broader research landscape can be demonstrated.

Remember to tailor the research paper conclusion to the specific needs and interests of your intended audience, which may include researchers, practitioners, policymakers, or a combination of these.

Frequently Asked Questions

A conclusion in a research paper is the final section where you summarize and wrap up your research, presenting the key findings and insights derived from your study. The research paper conclusion is not the place to introduce new information or data that was not discussed in the main body of the paper. When working on how to conclude a research paper, remember to stick to summarizing and interpreting existing content. The research paper conclusion serves the following purposes: 1

• Warn readers of the possible consequences of not attending to the problem.
• Recommend specific course(s) of action.
• Restate key ideas to drive home the ultimate point of your research paper.
• Provide a “take-home” message that you want the readers to remember about your study.

Types of conclusions for research papers

In research papers, the conclusion provides closure to the reader. The type of research paper conclusion you choose depends on the nature of your study, your goals, and your target audience. I provide you with three common types of conclusions:

A summarizing conclusion is the most common type of conclusion in research papers. It involves summarizing the main points, reiterating the research question, and restating the significance of the findings. This common type of research paper conclusion is used across different disciplines.

An editorial conclusion is less common but can be used in research papers that are focused on proposing or advocating for a particular viewpoint or policy. It involves presenting a strong editorial or opinion based on the research findings and offering recommendations or calls to action.

An externalizing conclusion is a type of conclusion that extends the research beyond the scope of the paper by suggesting potential future research directions or discussing the broader implications of the findings. This type of conclusion is often used in more theoretical or exploratory research papers.

The research paper conclusion is a crucial part of your paper as it provides the final opportunity to leave a strong impression on your readers. In the research paper conclusion, summarize the main points of your research paper by restating your research statement, highlighting the most important findings, addressing the research questions or objectives, explaining the broader context of the study, discussing the significance of your findings, providing recommendations if applicable, and emphasizing the takeaway message. The main purpose of the conclusion is to remind the reader of the main point or argument of your paper and to provide a clear and concise summary of the key findings and their implications. All these elements should feature on your list of what to put in the conclusion of a research paper to create a strong final statement for your work.

A strong conclusion is a critical component of a research paper, as it provides an opportunity to wrap up your arguments, reiterate your main points, and leave a lasting impression on your readers. Here are the key elements of a strong research paper conclusion: 1. Conciseness : A research paper conclusion should be concise and to the point. It should not introduce new information or ideas that were not discussed in the body of the paper. 2. Summarization : The research paper conclusion should be comprehensive enough to give the reader a clear understanding of the research’s main contributions. 3 . Relevance : Ensure that the information included in the research paper conclusion is directly relevant to the research paper’s main topic and objectives; avoid unnecessary details. 4 . Connection to the Introduction : A well-structured research paper conclusion often revisits the key points made in the introduction and shows how the research has addressed the initial questions or objectives. 5. Emphasis : Highlight the significance and implications of your research. Why is your study important? What are the broader implications or applications of your findings? 6 . Call to Action : Include a call to action or a recommendation for future research or action based on your findings.

The length of a research paper conclusion can vary depending on several factors, including the overall length of the paper, the complexity of the research, and the specific journal requirements. While there is no strict rule for the length of a conclusion, but it’s generally advisable to keep it relatively short. A typical research paper conclusion might be around 5-10% of the paper’s total length. For example, if your paper is 10 pages long, the conclusion might be roughly half a page to one page in length.

In general, you do not need to include citations in the research paper conclusion. Citations are typically reserved for the body of the paper to support your arguments and provide evidence for your claims. However, there may be some exceptions to this rule: 1. If you are drawing a direct quote or paraphrasing a specific source in your research paper conclusion, you should include a citation to give proper credit to the original author. 2. If your conclusion refers to or discusses specific research, data, or sources that are crucial to the overall argument, citations can be included to reinforce your conclusion’s validity.

The conclusion of a research paper serves several important purposes: 1. Summarize the Key Points 2. Reinforce the Main Argument 3. Provide Closure 4. Offer Insights or Implications 5. Engage the Reader. 6. Reflect on Limitations

Remember that the primary purpose of the research paper conclusion is to leave a lasting impression on the reader, reinforcing the key points and providing closure to your research. It’s often the last part of the paper that the reader will see, so it should be strong and well-crafted.

The conclusion is intended to help the reader understand why your research should matter to them after they have finished reading the paper. A conclusion is not merely a summary of the main topics covered or a re-statement of your research problem, but a synthesis of key points derived from the findings of your study and, if applicable, where you recommend new areas for future research. For most college-level research papers, two or three well-developed paragraphs is sufficient for a conclusion, although in some cases, more paragraphs may be required in describing the key findings and their significance.

Importance of a Good Conclusion

A well-written conclusion provides you with important opportunities to demonstrate to the reader your understanding of the research problem. These include:

• Presenting the last word on the issues you raised in your paper . Just as the introduction gives a first impression to your reader, the conclusion offers a chance to leave a lasting impression. Do this, for example, by highlighting key findings in your analysis that advance new understanding about the research problem, that are unusual or unexpected, or that have important implications applied to practice.
• Summarizing your thoughts and conveying the larger significance of your study . The conclusion is an opportunity to succinctly re-emphasize  your answer to the "So What?" question by placing the study within the context of how your research advances past research about the topic.
• Identifying how a gap in the literature has been addressed . The conclusion can be where you describe how a previously identified gap in the literature [first identified in your literature review section] has been addressed by your research and why this contribution is significant.
• Demonstrating the importance of your ideas . Don't be shy. The conclusion offers an opportunity to elaborate on the impact and significance of your findings. This is particularly important if your study approached examining the research problem from an unusual or innovative perspective.
• Introducing possible new or expanded ways of thinking about the research problem . This does not refer to introducing new information [which should be avoided], but to offer new insight and creative approaches for framing or contextualizing the research problem based on the results of your study.

Structure and Writing Style

I.  General Rules

The general function of your paper's conclusion is to restate the main argument . It reminds the reader of the strengths of your main argument(s) and reiterates the most important evidence supporting those argument(s). Do this by clearly summarizing the context, background, and necessity of pursuing the research problem you investigated in relation to an issue, controversy, or a gap found in the literature. However, make sure that your conclusion is not simply a repetitive summary of the findings. This reduces the impact of the argument(s) you have developed in your paper.

When writing the conclusion to your paper, follow these general rules:

• Present your conclusions in clear, concise language. Re-state the purpose of your study, then describe how your findings differ or support those of other studies and why [i.e., what were the unique, new, or crucial contributions your study made to the overall research about your topic?].
• Do not simply reiterate your findings or the discussion of your results. Provide a synthesis of arguments presented in the paper to show how these converge to address the research problem and the overall objectives of your study.
• Indicate opportunities for future research if you haven't already done so in the discussion section of your paper. Highlighting the need for further research provides the reader with evidence that you have an in-depth awareness of the research problem but that further investigations should take place beyond the scope of your investigation.

Consider the following points to help ensure your conclusion is presented well:

• If the argument or purpose of your paper is complex, you may need to summarize the argument for your reader.
• If, prior to your conclusion, you have not yet explained the significance of your findings or if you are proceeding inductively, use the end of your paper to describe your main points and explain their significance.
• Move from a detailed to a general level of consideration that returns the topic to the context provided by the introduction or within a new context that emerges from the data [this is opposite of the introduction, which begins with general discussion of the context and ends with a detailed description of the research problem]. 

The conclusion also provides a place for you to persuasively and succinctly restate the research problem, given that the reader has now been presented with all the information about the topic . Depending on the discipline you are writing in, the concluding paragraph may contain your reflections on the evidence presented. However, the nature of being introspective about the research you have conducted will depend on the topic and whether your professor wants you to express your observations in this way. If asked to think introspectively about the topics, do not delve into idle speculation. Being introspective means looking within yourself as an author to try and understand an issue more deeply, not to guess at possible outcomes or make up scenarios not supported by the evidence.

II.  Developing a Compelling Conclusion

Although an effective conclusion needs to be clear and succinct, it does not need to be written passively or lack a compelling narrative. Strategies to help you move beyond merely summarizing the key points of your research paper may include any of the following:

• If your essay deals with a critical, contemporary problem, warn readers of the possible consequences of not attending to the problem proactively.
• Recommend a specific course or courses of action that, if adopted, could address a specific problem in practice or in the development of new knowledge leading to positive change.
• Cite a relevant quotation or expert opinion already noted in your paper in order to lend authority and support to the conclusion(s) you have reached [a good source would be from your literature review].
• Explain the consequences of your research in a way that elicits action or demonstrates urgency in seeking change.
• Restate a key statistic, fact, or visual image to emphasize the most important finding of your paper.
• If your discipline encourages personal reflection, illustrate your concluding point by drawing from your own life experiences.
• Return to an anecdote, an example, or a quotation that you presented in your introduction, but add further insight derived from the findings of your study; use your interpretation of results from your study to recast it in new or important ways.
• Provide a "take-home" message in the form of a succinct, declarative statement that you want the reader to remember about your study.

III. Problems to Avoid

Failure to be concise Your conclusion section should be concise and to the point. Conclusions that are too lengthy often have unnecessary information in them. The conclusion is not the place for details about your methodology or results. Although you should give a summary of what was learned from your research, this summary should be relatively brief, since the emphasis in the conclusion is on the implications, evaluations, insights, and other forms of analysis that you make. Strategies for writing concisely can be found here .

Failure to comment on larger, more significant issues In the introduction, your task was to move from the general [the field of study] to the specific [the research problem]. However, in the conclusion, your task is to move from a specific discussion [your research problem] back to a general discussion framed around the implications and significance of your findings [i.e., how your research contributes new understanding or fills an important gap in the literature]. In short, the conclusion is where you should place your research within a larger context [visualize your paper as an hourglass--start with a broad introduction and review of the literature, move to the specific analysis and discussion, conclude with a broad summary of the study's implications and significance].

Failure to reveal problems and negative results Negative aspects of the research process should never be ignored. These are problems, deficiencies, or challenges encountered during your study. They should be summarized as a way of qualifying your overall conclusions. If you encountered negative or unintended results [i.e., findings that are validated outside the research context in which they were generated], you must report them in the results section and discuss their implications in the discussion section of your paper. In the conclusion, use negative results as an opportunity to explain their possible significance and/or how they may form the basis for future research.

Failure to provide a clear summary of what was learned In order to be able to discuss how your research fits within your field of study [and possibly the world at large], you need to summarize briefly and succinctly how it contributes to new knowledge or a new understanding about the research problem. This element of your conclusion may be only a few sentences long.

Failure to match the objectives of your research Often research objectives in the social and behavioral sciences change while the research is being carried out. This is not a problem unless you forget to go back and refine the original objectives in your introduction. As these changes emerge they must be documented so that they accurately reflect what you were trying to accomplish in your research [not what you thought you might accomplish when you began].

Resist the urge to apologize If you've immersed yourself in studying the research problem, you presumably should know a good deal about it [perhaps even more than your professor!]. Nevertheless, by the time you have finished writing, you may be having some doubts about what you have produced. Repress those doubts! Don't undermine your authority as a researcher by saying something like, "This is just one approach to examining this problem; there may be other, much better approaches that...." The overall tone of your conclusion should convey confidence to the reader about the study's validity and realiability.

Writing Tip

Don't Belabor the Obvious!

Avoid phrases like "in conclusion...," "in summary...," or "in closing...." These phrases can be useful, even welcome, in oral presentations. But readers can see by the tell-tale section heading and number of pages remaining that they are reaching the end of your paper. You'll irritate your readers if you belabor the obvious.

Assan, Joseph. "Writing the Conclusion Chapter: The Good, the Bad and the Missing." Liverpool: Development Studies Association (2009): 1-8.

Another Writing Tip

New Insight, Not New Information!

Don't surprise the reader with new information in your conclusion that was never referenced anywhere else in the paper. This why the conclusion rarely has citations to sources. If you have new information to present, add it to the discussion or other appropriate section of the paper. Note that, although no new information is introduced, the conclusion, along with the discussion section, is where you offer your most "original" contributions in the paper; the conclusion is where you describe the value of your research, demonstrate that you understand the material that you’ve presented, and position your findings within the larger context of scholarship on the topic, including describing how your research contributes new insights to that scholarship.

Research Paper Conclusion

Definition:

A research paper conclusion is the final section of a research paper that summarizes the key findings, significance, and implications of the research. It is the writer’s opportunity to synthesize the information presented in the paper, draw conclusions, and make recommendations for future research or actions.

The conclusion should provide a clear and concise summary of the research paper, reiterating the research question or problem, the main results, and the significance of the findings. It should also discuss the limitations of the study and suggest areas for further research.

Parts of Research Paper Conclusion

The parts of a research paper conclusion typically include:

Restatement of the Thesis

The conclusion should begin by restating the thesis statement from the introduction in a different way. This helps to remind the reader of the main argument or purpose of the research.

Summary of Key Findings

The conclusion should summarize the main findings of the research, highlighting the most important results and conclusions. This section should be brief and to the point.

Implications and Significance

In this section, the researcher should explain the implications and significance of the research findings. This may include discussing the potential impact on the field or industry, highlighting new insights or knowledge gained, or pointing out areas for future research.

Limitations and Recommendations

It is important to acknowledge any limitations or weaknesses of the research and to make recommendations for how these could be addressed in future studies. This shows that the researcher is aware of the potential limitations of their work and is committed to improving the quality of research in their field.

Concluding Statement

The conclusion should end with a strong concluding statement that leaves a lasting impression on the reader. This could be a call to action, a recommendation for further research, or a final thought on the topic.

How to Write Research Paper Conclusion

Here are some steps you can follow to write an effective research paper conclusion:

• Restate the research problem or question: Begin by restating the research problem or question that you aimed to answer in your research. This will remind the reader of the purpose of your study.
• Summarize the main points: Summarize the key findings and results of your research. This can be done by highlighting the most important aspects of your research and the evidence that supports them.
• Discuss the implications: Discuss the implications of your findings for the research area and any potential applications of your research. You should also mention any limitations of your research that may affect the interpretation of your findings.
• Provide a conclusion : Provide a concise conclusion that summarizes the main points of your paper and emphasizes the significance of your research. This should be a strong and clear statement that leaves a lasting impression on the reader.
• Offer suggestions for future research: Lastly, offer suggestions for future research that could build on your findings and contribute to further advancements in the field.

Remember that the conclusion should be brief and to the point, while still effectively summarizing the key findings and implications of your research.

Example of Research Paper Conclusion

Here’s an example of a research paper conclusion:

Conclusion :

In conclusion, our study aimed to investigate the relationship between social media use and mental health among college students. Our findings suggest that there is a significant association between social media use and increased levels of anxiety and depression among college students. This highlights the need for increased awareness and education about the potential negative effects of social media use on mental health, particularly among college students.

Despite the limitations of our study, such as the small sample size and self-reported data, our findings have important implications for future research and practice. Future studies should aim to replicate our findings in larger, more diverse samples, and investigate the potential mechanisms underlying the association between social media use and mental health. In addition, interventions should be developed to promote healthy social media use among college students, such as mindfulness-based approaches and social media detox programs.

Overall, our study contributes to the growing body of research on the impact of social media on mental health, and highlights the importance of addressing this issue in the context of higher education. By raising awareness and promoting healthy social media use among college students, we can help to reduce the negative impact of social media on mental health and improve the well-being of young adults.

Purpose of Research Paper Conclusion

The purpose of a research paper conclusion is to provide a summary and synthesis of the key findings, significance, and implications of the research presented in the paper. The conclusion serves as the final opportunity for the writer to convey their message and leave a lasting impression on the reader.

The conclusion should restate the research problem or question, summarize the main results of the research, and explain their significance. It should also acknowledge the limitations of the study and suggest areas for future research or action.

Overall, the purpose of the conclusion is to provide a sense of closure to the research paper and to emphasize the importance of the research and its potential impact. It should leave the reader with a clear understanding of the main findings and why they matter. The conclusion serves as the writer’s opportunity to showcase their contribution to the field and to inspire further research and action.

When to Write Research Paper Conclusion

The conclusion of a research paper should be written after the body of the paper has been completed. It should not be written until the writer has thoroughly analyzed and interpreted their findings and has written a complete and cohesive discussion of the research.

Before writing the conclusion, the writer should review their research paper and consider the key points that they want to convey to the reader. They should also review the research question, hypotheses, and methodology to ensure that they have addressed all of the necessary components of the research.

Once the writer has a clear understanding of the main findings and their significance, they can begin writing the conclusion. The conclusion should be written in a clear and concise manner, and should reiterate the main points of the research while also providing insights and recommendations for future research or action.

Characteristics of Research Paper Conclusion

The characteristics of a research paper conclusion include:

• Clear and concise: The conclusion should be written in a clear and concise manner, summarizing the key findings and their significance.
• Comprehensive: The conclusion should address all of the main points of the research paper, including the research question or problem, the methodology, the main results, and their implications.
• Future-oriented : The conclusion should provide insights and recommendations for future research or action, based on the findings of the research.
• Impressive : The conclusion should leave a lasting impression on the reader, emphasizing the importance of the research and its potential impact.
• Objective : The conclusion should be based on the evidence presented in the research paper, and should avoid personal biases or opinions.
• Unique : The conclusion should be unique to the research paper and should not simply repeat information from the introduction or body of the paper.

Advantages of Research Paper Conclusion

The advantages of a research paper conclusion include:

• Summarizing the key findings : The conclusion provides a summary of the main findings of the research, making it easier for the reader to understand the key points of the study.
• Emphasizing the significance of the research: The conclusion emphasizes the importance of the research and its potential impact, making it more likely that readers will take the research seriously and consider its implications.
• Providing recommendations for future research or action : The conclusion suggests practical recommendations for future research or action, based on the findings of the study.
• Providing closure to the research paper : The conclusion provides a sense of closure to the research paper, tying together the different sections of the paper and leaving a lasting impression on the reader.
• Demonstrating the writer’s contribution to the field : The conclusion provides the writer with an opportunity to showcase their contribution to the field and to inspire further research and action.

Limitations of Research Paper Conclusion

While the conclusion of a research paper has many advantages, it also has some limitations that should be considered, including:

• I nability to address all aspects of the research: Due to the limited space available in the conclusion, it may not be possible to address all aspects of the research in detail.
• Subjectivity : While the conclusion should be objective, it may be influenced by the writer’s personal biases or opinions.
• Lack of new information: The conclusion should not introduce new information that has not been discussed in the body of the research paper.
• Lack of generalizability: The conclusions drawn from the research may not be applicable to other contexts or populations, limiting the generalizability of the study.
• Misinterpretation by the reader: The reader may misinterpret the conclusions drawn from the research, leading to a misunderstanding of the findings.

How to Write a Conclusion for a Research Paper

3-minute read

• 29th August 2023

If you’re writing a research paper, the conclusion is your opportunity to summarize your findings and leave a lasting impression on your readers. In this post, we’ll take you through how to write an effective conclusion for a research paper and how you can:

·   Reword your thesis statement

·   Highlight the significance of your research

·   Discuss limitations

·   Connect to the introduction

·   End with a thought-provoking statement

Rewording Your Thesis Statement

Begin your conclusion by restating your thesis statement in a way that is slightly different from the wording used in the introduction. Avoid presenting new information or evidence in your conclusion. Just summarize the main points and arguments of your essay and keep this part as concise as possible. Remember that you’ve already covered the in-depth analyses and investigations in the main body paragraphs of your essay, so it’s not necessary to restate these details in the conclusion.

Highlighting the Significance of Your Research

The conclusion is a good place to emphasize the implications of your research . Avoid ambiguous or vague language such as “I think” or “maybe,” which could weaken your position. Clearly explain why your research is significant and how it contributes to the broader field of study.

Here’s an example from a (fictional) study on the impact of social media on mental health:

Discussing Limitations

Although it’s important to emphasize the significance of your study, you can also use the conclusion to briefly address any limitations you discovered while conducting your research, such as time constraints or a shortage of resources. Doing this demonstrates a balanced and honest approach to your research.

Connecting to the Introduction

In your conclusion, you can circle back to your introduction , perhaps by referring to a quote or anecdote you discussed earlier. If you end your paper on a similar note to how you began it, you will create a sense of cohesion for the reader and remind them of the meaning and significance of your research.

Ending With a Thought-Provoking Statement

Consider ending your paper with a thought-provoking and memorable statement that relates to the impact of your research questions or hypothesis. This statement can be a call to action, a philosophical question, or a prediction for the future (positive or negative). Here’s an example that uses the same topic as above (social media and mental health):

In a short paper—even a research paper—you don’t need to provide an exhaustive summary as part of your conclusion. But you do need to make some kind of transition between your final body paragraph and your concluding paragraph. This may come in the form of a few sentences of summary. Or it may come in the form of a sentence that brings your readers back to your thesis or main idea and reminds your readers where you began and how far you have traveled.

So, for example, in a paper about the relationship between ADHD and rejection sensitivity, Vanessa Roser begins by introducing readers to the fact that researchers have studied the relationship between the two conditions and then provides her explanation of that relationship. Here’s her thesis: “While socialization may indeed be an important factor in RS, I argue that individuals with ADHD may also possess a neurological predisposition to RS that is exacerbated by the differing executive and emotional regulation characteristic of ADHD.”

In her final paragraph, Roser reminds us of where she started by echoing her thesis: “This literature demonstrates that, as with many other conditions, ADHD and RS share a delicately intertwined pattern of neurological similarities that is rooted in the innate biology of an individual’s mind, a connection that cannot be explained in full by the behavioral mediation hypothesis.”  

Highlight the “so what”  

At the beginning of your paper, you explain to your readers what’s at stake—why they should care about the argument you’re making. In your conclusion, you can bring readers back to those stakes by reminding them why your argument is important in the first place. You can also draft a few sentences that put those stakes into a new or broader context.

In the conclusion to her paper about ADHD and RS, Roser echoes the stakes she established in her introduction—that research into connections between ADHD and RS has led to contradictory results, raising questions about the “behavioral mediation hypothesis.”

She writes, “as with many other conditions, ADHD and RS share a delicately intertwined pattern of neurological similarities that is rooted in the innate biology of an individual’s mind, a connection that cannot be explained in full by the behavioral mediation hypothesis.”  

Leave your readers with the “now what”  

After the “what” and the “so what,” you should leave your reader with some final thoughts. If you have written a strong introduction, your readers will know why you have been arguing what you have been arguing—and why they should care. And if you’ve made a good case for your thesis, then your readers should be in a position to see things in a new way, understand new questions, or be ready for something that they weren’t ready for before they read your paper.

In her conclusion, Roser offers two “now what” statements. First, she explains that it is important to recognize that the flawed behavioral mediation hypothesis “seems to place a degree of fault on the individual. It implies that individuals with ADHD must have elicited such frequent or intense rejection by virtue of their inadequate social skills, erasing the possibility that they may simply possess a natural sensitivity to emotion.” She then highlights the broader implications for treatment of people with ADHD, noting that recognizing the actual connection between rejection sensitivity and ADHD “has profound implications for understanding how individuals with ADHD might best be treated in educational settings, by counselors, family, peers, or even society as a whole.”

To find your own “now what” for your essay’s conclusion, try asking yourself these questions:

• What can my readers now understand, see in a new light, or grapple with that they would not have understood in the same way before reading my paper? Are we a step closer to understanding a larger phenomenon or to understanding why what was at stake is so important?  
• What questions can I now raise that would not have made sense at the beginning of my paper? Questions for further research? Other ways that this topic could be approached?  
• Are there other applications for my research? Could my questions be asked about different data in a different context? Could I use my methods to answer a different question?  
• What action should be taken in light of this argument? What action do I predict will be taken or could lead to a solution?  
• What larger context might my argument be a part of?  

What to avoid in your conclusion  

• a complete restatement of all that you have said in your paper.  
• a substantial counterargument that you do not have space to refute; you should introduce counterarguments before your conclusion.  
• an apology for what you have not said. If you need to explain the scope of your paper, you should do this sooner—but don’t apologize for what you have not discussed in your paper.  
• fake transitions like “in conclusion” that are followed by sentences that aren’t actually conclusions. (“In conclusion, I have now demonstrated that my thesis is correct.”)

How to Conclude an Essay | Interactive Example

Published on January 24, 2019 by Shona McCombes . Revised on July 23, 2023.

The conclusion is the final paragraph of your essay . A strong conclusion aims to:

• Tie together the essay’s main points
• Show why your argument matters
• Leave the reader with a strong impression

Your conclusion should give a sense of closure and completion to your argument, but also show what new questions or possibilities it has opened up.

This conclusion is taken from our annotated essay example , which discusses the history of the Braille system. Hover over each part to see why it’s effective.

Braille paved the way for dramatic cultural changes in the way blind people were treated and the opportunities available to them. Louis Braille’s innovation was to reimagine existing reading systems from a blind perspective, and the success of this invention required sighted teachers to adapt to their students’ reality instead of the other way around. In this sense, Braille helped drive broader social changes in the status of blindness. New accessibility tools provide practical advantages to those who need them, but they can also change the perspectives and attitudes of those who do not.

To begin your conclusion, signal that the essay is coming to an end by returning to your overall argument.

Don’t just repeat your thesis statement —instead, try to rephrase your argument in a way that shows how it has been developed since the introduction.

Prevent plagiarism. Run a free check.

Next, remind the reader of the main points that you used to support your argument.

Avoid simply summarizing each paragraph or repeating each point in order; try to bring your points together in a way that makes the connections between them clear. The conclusion is your final chance to show how all the paragraphs of your essay add up to a coherent whole.

To wrap up your conclusion, zoom out to a broader view of the topic and consider the implications of your argument. For example:

• Does it contribute a new understanding of your topic?
• Does it raise new questions for future study?
• Does it lead to practical suggestions or predictions?
• Can it be applied to different contexts?
• Can it be connected to a broader debate or theme?

Whatever your essay is about, the conclusion should aim to emphasize the significance of your argument, whether that’s within your academic subject or in the wider world.

Try to end with a strong, decisive sentence, leaving the reader with a lingering sense of interest in your topic.

The easiest way to improve your conclusion is to eliminate these common mistakes.

Don’t include new evidence

Any evidence or analysis that is essential to supporting your thesis statement should appear in the main body of the essay.

The conclusion might include minor pieces of new information—for example, a sentence or two discussing broader implications, or a quotation that nicely summarizes your central point. But it shouldn’t introduce any major new sources or ideas that need further explanation to understand.

Don’t use “concluding phrases”

Avoid using obvious stock phrases to tell the reader what you’re doing:

• “In conclusion…”
• “To sum up…”

These phrases aren’t forbidden, but they can make your writing sound weak. By returning to your main argument, it will quickly become clear that you are concluding the essay—you shouldn’t have to spell it out.

Don’t undermine your argument

Avoid using apologetic phrases that sound uncertain or confused:

• “This is just one approach among many.”
• “There are good arguments on both sides of this issue.”
• “There is no clear answer to this problem.”

Even if your essay has explored different points of view, your own position should be clear. There may be many possible approaches to the topic, but you want to leave the reader convinced that yours is the best one!

This conclusion is taken from an argumentative essay about the internet’s impact on education. It acknowledges the opposing arguments while taking a clear, decisive position.

The internet has had a major positive impact on the world of education; occasional pitfalls aside, its value is evident in numerous applications. The future of teaching lies in the possibilities the internet opens up for communication, research, and interactivity. As the popularity of distance learning shows, students value the flexibility and accessibility offered by digital education, and educators should fully embrace these advantages. The internet’s dangers, real and imaginary, have been documented exhaustively by skeptics, but the internet is here to stay; it is time to focus seriously on its potential for good.

This conclusion is taken from a short expository essay that explains the invention of the printing press and its effects on European society. It focuses on giving a clear, concise overview of what was covered in the essay.

The invention of the printing press was important not only in terms of its immediate cultural and economic effects, but also in terms of its major impact on politics and religion across Europe. In the century following the invention of the printing press, the relatively stationary intellectual atmosphere of the Middle Ages gave way to the social upheavals of the Reformation and the Renaissance. A single technological innovation had contributed to the total reshaping of the continent.

This conclusion is taken from a literary analysis essay about Mary Shelley’s Frankenstein . It summarizes what the essay’s analysis achieved and emphasizes its originality.

By tracing the depiction of Frankenstein through the novel’s three volumes, I have demonstrated how the narrative structure shifts our perception of the character. While the Frankenstein of the first volume is depicted as having innocent intentions, the second and third volumes—first in the creature’s accusatory voice, and then in his own voice—increasingly undermine him, causing him to appear alternately ridiculous and vindictive. Far from the one-dimensional villain he is often taken to be, the character of Frankenstein is compelling because of the dynamic narrative frame in which he is placed. In this frame, Frankenstein’s narrative self-presentation responds to the images of him we see from others’ perspectives. This conclusion sheds new light on the novel, foregrounding Shelley’s unique layering of narrative perspectives and its importance for the depiction of character.

Your essay’s conclusion should contain:

• A rephrased version of your overall thesis
• A brief review of the key points you made in the main body
• An indication of why your argument matters

The conclusion may also reflect on the broader implications of your argument, showing how your ideas could applied to other contexts or debates.

For a stronger conclusion paragraph, avoid including:

• Important evidence or analysis that wasn’t mentioned in the main body
• Generic concluding phrases (e.g. “In conclusion…”)
• Weak statements that undermine your argument (e.g. “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

The conclusion paragraph of an essay is usually shorter than the introduction . As a rule, it shouldn’t take up more than 10–15% of the text.

Conclusions

What this handout is about.

This handout will explain the functions of conclusions, offer strategies for writing effective ones, help you evaluate conclusions you’ve drafted, and suggest approaches to avoid.

About conclusions

Introductions and conclusions can be difficult to write, but they’re worth investing time in. They can have a significant influence on a reader’s experience of your paper.

Just as your introduction acts as a bridge that transports your readers from their own lives into the “place” of your analysis, your conclusion can provide a bridge to help your readers make the transition back to their daily lives. Such a conclusion will help them see why all your analysis and information should matter to them after they put the paper down.

Your conclusion is your chance to have the last word on the subject. The conclusion allows you to have the final say on the issues you have raised in your paper, to synthesize your thoughts, to demonstrate the importance of your ideas, and to propel your reader to a new view of the subject. It is also your opportunity to make a good final impression and to end on a positive note.

Your conclusion can go beyond the confines of the assignment. The conclusion pushes beyond the boundaries of the prompt and allows you to consider broader issues, make new connections, and elaborate on the significance of your findings.

Your conclusion should make your readers glad they read your paper. Your conclusion gives your reader something to take away that will help them see things differently or appreciate your topic in personally relevant ways. It can suggest broader implications that will not only interest your reader, but also enrich your reader’s life in some way. It is your gift to the reader.

Strategies for writing an effective conclusion

One or more of the following strategies may help you write an effective conclusion:

• Play the “So What” Game. If you’re stuck and feel like your conclusion isn’t saying anything new or interesting, ask a friend to read it with you. Whenever you make a statement from your conclusion, ask the friend to say, “So what?” or “Why should anybody care?” Then ponder that question and answer it. Here’s how it might go: You: Basically, I’m just saying that education was important to Douglass. Friend: So what? You: Well, it was important because it was a key to him feeling like a free and equal citizen. Friend: Why should anybody care? You: That’s important because plantation owners tried to keep slaves from being educated so that they could maintain control. When Douglass obtained an education, he undermined that control personally. You can also use this strategy on your own, asking yourself “So What?” as you develop your ideas or your draft.
• Return to the theme or themes in the introduction. This strategy brings the reader full circle. For example, if you begin by describing a scenario, you can end with the same scenario as proof that your essay is helpful in creating a new understanding. You may also refer to the introductory paragraph by using key words or parallel concepts and images that you also used in the introduction.
• Synthesize, don’t summarize. Include a brief summary of the paper’s main points, but don’t simply repeat things that were in your paper. Instead, show your reader how the points you made and the support and examples you used fit together. Pull it all together.
• Include a provocative insight or quotation from the research or reading you did for your paper.
• Propose a course of action, a solution to an issue, or questions for further study. This can redirect your reader’s thought process and help them to apply your info and ideas to their own life or to see the broader implications.
• Point to broader implications. For example, if your paper examines the Greensboro sit-ins or another event in the Civil Rights Movement, you could point out its impact on the Civil Rights Movement as a whole. A paper about the style of writer Virginia Woolf could point to her influence on other writers or on later feminists.

Strategies to avoid

• Beginning with an unnecessary, overused phrase such as “in conclusion,” “in summary,” or “in closing.” Although these phrases can work in speeches, they come across as wooden and trite in writing.
• Stating the thesis for the very first time in the conclusion.
• Introducing a new idea or subtopic in your conclusion.
• Ending with a rephrased thesis statement without any substantive changes.
• Making sentimental, emotional appeals that are out of character with the rest of an analytical paper.
• Including evidence (quotations, statistics, etc.) that should be in the body of the paper.

Four kinds of ineffective conclusions

• The “That’s My Story and I’m Sticking to It” Conclusion. This conclusion just restates the thesis and is usually painfully short. It does not push the ideas forward. People write this kind of conclusion when they can’t think of anything else to say. Example: In conclusion, Frederick Douglass was, as we have seen, a pioneer in American education, proving that education was a major force for social change with regard to slavery.
• The “Sherlock Holmes” Conclusion. Sometimes writers will state the thesis for the very first time in the conclusion. You might be tempted to use this strategy if you don’t want to give everything away too early in your paper. You may think it would be more dramatic to keep the reader in the dark until the end and then “wow” them with your main idea, as in a Sherlock Holmes mystery. The reader, however, does not expect a mystery, but an analytical discussion of your topic in an academic style, with the main argument (thesis) stated up front. Example: (After a paper that lists numerous incidents from the book but never says what these incidents reveal about Douglass and his views on education): So, as the evidence above demonstrates, Douglass saw education as a way to undermine the slaveholders’ power and also an important step toward freedom.
• The “America the Beautiful”/”I Am Woman”/”We Shall Overcome” Conclusion. This kind of conclusion usually draws on emotion to make its appeal, but while this emotion and even sentimentality may be very heartfelt, it is usually out of character with the rest of an analytical paper. A more sophisticated commentary, rather than emotional praise, would be a more fitting tribute to the topic. Example: Because of the efforts of fine Americans like Frederick Douglass, countless others have seen the shining beacon of light that is education. His example was a torch that lit the way for others. Frederick Douglass was truly an American hero.
• The “Grab Bag” Conclusion. This kind of conclusion includes extra information that the writer found or thought of but couldn’t integrate into the main paper. You may find it hard to leave out details that you discovered after hours of research and thought, but adding random facts and bits of evidence at the end of an otherwise-well-organized essay can just create confusion. Example: In addition to being an educational pioneer, Frederick Douglass provides an interesting case study for masculinity in the American South. He also offers historians an interesting glimpse into slave resistance when he confronts Covey, the overseer. His relationships with female relatives reveal the importance of family in the slave community.

• How to Write Discussions and Conclusions

The discussion section contains the results and outcomes of a study. An effective discussion informs readers what can be learned from your experiment and provides context for the results.

What makes an effective discussion?

When you’re ready to write your discussion, you’ve already introduced the purpose of your study and provided an in-depth description of the methodology. The discussion informs readers about the larger implications of your study based on the results. Highlighting these implications while not overstating the findings can be challenging, especially when you’re submitting to a journal that selects articles based on novelty or potential impact. Regardless of what journal you are submitting to, the discussion section always serves the same purpose: concluding what your study results actually mean.

A successful discussion section puts your findings in context. It should include:

• the results of your research,
• a discussion of related research, and
• a comparison between your results and initial hypothesis.

Tip: Not all journals share the same naming conventions.

You can apply the advice in this article to the conclusion, results or discussion sections of your manuscript.

Our Early Career Researcher community tells us that the conclusion is often considered the most difficult aspect of a manuscript to write. To help, this guide provides questions to ask yourself, a basic structure to model your discussion off of and examples from published manuscripts. 

Questions to ask yourself:

• Was my hypothesis correct?
• If my hypothesis is partially correct or entirely different, what can be learned from the results? 
• How do the conclusions reshape or add onto the existing knowledge in the field? What does previous research say about the topic? 
• Why are the results important or relevant to your audience? Do they add further evidence to a scientific consensus or disprove prior studies? 
• How can future research build on these observations? What are the key experiments that must be done? 
• What is the “take-home” message you want your reader to leave with?

How to structure a discussion

Trying to fit a complete discussion into a single paragraph can add unnecessary stress to the writing process. If possible, you’ll want to give yourself two or three paragraphs to give the reader a comprehensive understanding of your study as a whole. Here’s one way to structure an effective discussion:

Writing Tips

While the above sections can help you brainstorm and structure your discussion, there are many common mistakes that writers revert to when having difficulties with their paper. Writing a discussion can be a delicate balance between summarizing your results, providing proper context for your research and avoiding introducing new information. Remember that your paper should be both confident and honest about the results! 

• Read the journal’s guidelines on the discussion and conclusion sections. If possible, learn about the guidelines before writing the discussion to ensure you’re writing to meet their expectations. 
• Begin with a clear statement of the principal findings. This will reinforce the main take-away for the reader and set up the rest of the discussion. 
• Explain why the outcomes of your study are important to the reader. Discuss the implications of your findings realistically based on previous literature, highlighting both the strengths and limitations of the research. 
• State whether the results prove or disprove your hypothesis. If your hypothesis was disproved, what might be the reasons? 
• Introduce new or expanded ways to think about the research question. Indicate what next steps can be taken to further pursue any unresolved questions. 
• If dealing with a contemporary or ongoing problem, such as climate change, discuss possible consequences if the problem is avoided. 
• Be concise. Adding unnecessary detail can distract from the main findings. 

Don’t

• Rewrite your abstract. Statements with “we investigated” or “we studied” generally do not belong in the discussion. 
• Include new arguments or evidence not previously discussed. Necessary information and evidence should be introduced in the main body of the paper. 
• Apologize. Even if your research contains significant limitations, don’t undermine your authority by including statements that doubt your methodology or execution. 
• Shy away from speaking on limitations or negative results. Including limitations and negative results will give readers a complete understanding of the presented research. Potential limitations include sources of potential bias, threats to internal or external validity, barriers to implementing an intervention and other issues inherent to the study design. 
• Overstate the importance of your findings. Making grand statements about how a study will fully resolve large questions can lead readers to doubt the success of the research.

How to Write a Conclusion for a Research Paper

The conclusion of a research paper needs to summarize the content and purpose of the paper without seeming too wooden or dry. Every basic conclusion must share several key elements, but there are also several tactics you can play around with to craft a more effective conclusion and several you should avoid to prevent yourself from weakening your paper's conclusion. Here are some writing tips to keep in mind when creating a conclusion for your next research paper.

Sample Conclusions

Writing a basic conclusion.

• Do not spend a great amount of time or space restating your topic.
• A good research paper will make the importance of your topic apparent, so you do not need to write an elaborate defense of your topic in the conclusion.
• Usually a single sentence is all you need to restate your topic.
• An example would be if you were writing a paper on the epidemiology of infectious disease, you might say something like "Tuberculosis is a widespread infectious disease that affects millions of people worldwide every year."
• Yet another example from the humanities would be a paper about the Italian Renaissance: "The Italian Renaissance was an explosion of art and ideas centered around artists, writers, and thinkers in Florence."

• A thesis is a narrowed, focused view on the topic at hand.
• This statement should be rephrased from the thesis you included in your introduction. It should not be identical or too similar to the sentence you originally used.
• Try re-wording your thesis statement in a way that complements your summary of the topic of your paper in your first sentence of your conclusion.
• An example of a good thesis statement, going back to the paper on tuberculosis, would be "Tuberculosis is a widespread disease that affects millions of people worldwide every year. Due to the alarming rate of the spread of tuberculosis, particularly in poor countries, medical professionals are implementing new strategies for the diagnosis, treatment, and containment of this disease ."

• A good way to go about this is to re-read the topic sentence of each major paragraph or section in the body of your paper.
• Find a way to briefly restate each point mentioned in each topic sentence in your conclusion. Do not repeat any of the supporting details used within your body paragraphs.
• Under most circumstances, you should avoid writing new information in your conclusion. This is especially true if the information is vital to the argument or research presented in your paper.
• For example, in the TB paper you could summarize the information. "Tuberculosis is a widespread disease that affects millions of people worldwide. Due to the alarming rate of the spread of tuberculosis, particularly in poor countries, medical professionals are implementing new strategies for the diagnosis, treatment, and containment of this disease. In developing countries, such as those in Africa and Southeast Asia, the rate of TB infections is soaring. Crowded conditions, poor sanitation, and lack of access to medical care are all compounding factors in the spread of the disease. Medical experts, such as those from the World Health Organization are now starting campaigns to go into communities in developing countries and provide diagnostic testing and treatments. However, the treatments for TB are very harsh and have many side effects. This leads to patient non-compliance and spread of multi-drug resistant strains of the disease."

• Note that this is not needed for all research papers.
• If you already fully explained what the points in your paper mean or why they are significant, you do not need to go into them in much detail in your conclusion. Simply restating your thesis or the significance of your topic should suffice.
• It is always best practice to address important issues and fully explain your points in the body of your paper. The point of a conclusion to a research paper is to summarize your argument for the reader and, perhaps, to call the reader to action if needed.

• Note that a call for action is not essential to all conclusions. A research paper on literary criticism, for instance, is less likely to need a call for action than a paper on the effect that television has on toddlers and young children.
• A paper that is more likely to call readers to action is one that addresses a public or scientific need. Let's go back to our example of tuberculosis. This is a very serious disease that is spreading quickly and with antibiotic-resistant forms.
• A call to action in this research paper would be a follow-up statement that might be along the lines of "Despite new efforts to diagnose and contain the disease, more research is needed to develop new antibiotics that will treat the most resistant strains of tuberculosis and ease the side effects of current treatments."

• For example, if you are writing a history paper, then you might discuss how the historical topic you discussed matters today. If you are writing about a foreign country, then you might use the conclusion to discuss how the information you shared may help readers understand their own country.

Making Your Conclusion as Effective as Possible

• Since this sort of conclusion is so basic, you must aim to synthesize the information rather than merely summarizing it.
• Instead of merely repeating things you already said, rephrase your thesis and supporting points in a way that ties them all together.
• By doing so, you make your research paper seem like a "complete thought" rather than a collection of random and vaguely related ideas.

• Ask a question in your introduction. In your conclusion, restate the question and provide a direct answer.
• Write an anecdote or story in your introduction but do not share the ending. Instead, write the conclusion to the anecdote in the conclusion of your paper.
• For example, if you wanted to get more creative and put a more humanistic spin on a paper on tuberculosis, you might start your introduction with a story about a person with the disease, and refer to that story in your conclusion. For example, you could say something like this before you re-state your thesis in your conclusion: "Patient X was unable to complete the treatment for tuberculosis due to severe side effects and unfortunately succumbed to the disease."
• Use the same concepts and images introduced in your introduction in your conclusion. The images may or may not appear at other points throughout the research paper.

• Include enough information about your topic to back the statement up but do not get too carried away with excess detail.
• If your research did not provide you with a clear-cut answer to a question posed in your thesis, do not be afraid to indicate as much.
• Restate your initial hypothesis and indicate whether you still believe it or if the research you performed has begun swaying your opinion.
• Indicate that an answer may still exist and that further research could shed more light on the topic at hand.

• This may not be appropriate for all types of research papers. Most research papers, such as one on effective treatment for diseases, will have the information to make the case for a particular argument already in the paper.
• A good example of a paper that might ask a question of the reader in the ending is one about a social issue, such as poverty or government policy.
• Ask a question that will directly get at the heart or purpose of the paper. This question is often the same question, or some version of it, that you may have started with when you began your research.
• Make sure that the question can be answered by the evidence presented in your paper.
• If desired you can briefly summarize the answer after stating the question. You could also leave the question hanging for the reader to answer, though.

• Even without a call to action, you can still make a recommendation to your reader.
• For instance, if you are writing about a topic like third-world poverty, you can various ways for the reader to assist in the problem without necessarily calling for more research.
• Another example would be, in a paper about treatment for drug-resistant tuberculosis, you could suggest donating to the World Health Organization or research foundations that are developing new treatments for the disease.

Avoiding Common Pitfalls

• These sayings usually sound stiff, unnatural, or trite when used in writing.
• Moreover, using a phrase like "in conclusion" to begin your conclusion is a little too straightforward and tends to lead to a weak conclusion. A strong conclusion can stand on its own without being labeled as such.

• Always state the main argument or thesis in the introduction. A research paper is an analytical discussion of an academic topic, not a mystery novel.
• A good, effective research paper will allow your reader to follow your main argument from start to finish.
• This is why it is best practice to start your paper with an introduction that states your main argument and to end the paper with a conclusion that re-states your thesis for re-iteration.

• All significant information should be introduced in the body of the paper.
• Supporting evidence expands the topic of your paper by making it appear more detailed. A conclusion should narrow the topic to a more general point.
• A conclusion should only summarize what you have already stated in the body of your paper.
• You may suggest further research or a call to action, but you should not bring in any new evidence or facts in the conclusion.

• Most often, a shift in tone occurs when a research paper with an academic tone gives an emotional or sentimental conclusion.
• Even if the topic of the paper is of personal significance for you, you should not indicate as much in your paper.
• If you want to give your paper a more humanistic slant, you could start and end your paper with a story or anecdote that would give your topic more personal meaning to the reader.
• This tone should be consistent throughout the paper, however.

• Apologetic statements include phrases like "I may not be an expert" or "This is only my opinion."
• Statements like this can usually be avoided by refraining from writing in the first-person.
• Avoid any statements in the first-person. First-person is generally considered to be informal and does not fit with the formal tone of a research paper.

How to write a strong conclusion for your research paper

Last updated

17 February 2024

Reviewed by

Writing a research paper is a chance to share your knowledge and hypothesis. It's an opportunity to demonstrate your many hours of research and prove your ability to write convincingly.

Ideally, by the end of your research paper, you'll have brought your readers on a journey to reach the conclusions you've pre-determined. However, if you don't stick the landing with a good conclusion, you'll risk losing your reader’s trust.

Writing a strong conclusion for your research paper involves a few important steps, including restating the thesis and summing up everything properly.

Find out what to include and what to avoid, so you can effectively demonstrate your understanding of the topic and prove your expertise.

• Why is a good conclusion important?

A good conclusion can cement your paper in the reader’s mind. Making a strong impression in your introduction can draw your readers in, but it's the conclusion that will inspire them.

• What to include in a research paper conclusion

There are a few specifics you should include in your research paper conclusion. Offer your readers some sense of urgency or consequence by pointing out why they should care about the topic you have covered. Discuss any common problems associated with your topic and provide suggestions as to how these problems can be solved or addressed.

The conclusion should include a restatement of your initial thesis. Thesis statements are strengthened after you’ve presented supporting evidence (as you will have done in the paper), so make a point to reintroduce it at the end.

Finally, recap the main points of your research paper, highlighting the key takeaways you want readers to remember. If you've made multiple points throughout the paper, refer to the ones with the strongest supporting evidence.

• Steps for writing a research paper conclusion

Many writers find the conclusion the most challenging part of any research project . By following these three steps, you'll be prepared to write a conclusion that is effective and concise.

• Step 1: Restate the problem

Always begin by restating the research problem in the conclusion of a research paper. This serves to remind the reader of your hypothesis and refresh them on the main point of the paper. 

When restating the problem, take care to avoid using exactly the same words you employed earlier in the paper.

• Step 2: Sum up the paper

After you've restated the problem, sum up the paper by revealing your overall findings. The method for this differs slightly, depending on whether you're crafting an argumentative paper or an empirical paper.

Argumentative paper: Restate your thesis and arguments

Argumentative papers involve introducing a thesis statement early on. In crafting the conclusion for an argumentative paper, always restate the thesis, outlining the way you've developed it throughout the entire paper.

It might be appropriate to mention any counterarguments in the conclusion, so you can demonstrate how your thesis is correct or how the data best supports your main points.

Empirical paper: Summarize research findings

Empirical papers break down a series of research questions. In your conclusion, discuss the findings your research revealed, including any information that surprised you.

Be clear about the conclusions you reached, and explain whether or not you expected to arrive at these particular ones.

• Step 3: Discuss the implications of your research

Argumentative papers and empirical papers also differ in this part of a research paper conclusion. Here are some tips on crafting conclusions for argumentative and empirical papers.

Argumentative paper: Powerful closing statement

In an argumentative paper, you'll have spent a great deal of time expressing the opinions you formed after doing a significant amount of research. Make a strong closing statement in your argumentative paper's conclusion to share the significance of your work.

You can outline the next steps through a bold call to action, or restate how powerful your ideas turned out to be.

Empirical paper: Directions for future research

Empirical papers are broader in scope. They usually cover a variety of aspects and can include several points of view.

To write a good conclusion for an empirical paper, suggest the type of research that could be done in the future, including methods for further investigation or outlining ways other researchers might proceed.

If you feel your research had any limitations, even if they were outside your control, you could mention these in your conclusion.

After you finish outlining your conclusion, ask someone to read it and offer feedback. In any research project you're especially close to, it can be hard to identify problem areas. Having a close friend or someone whose opinion you value read the research paper and provide honest feedback can be invaluable. Take note of any suggested edits and consider incorporating them into your paper if they make sense.

• Things to avoid in a research paper conclusion

Keep these aspects to avoid in mind as you're writing your conclusion and refer to them after you've created an outline.

Dry summary

Writing a memorable, succinct conclusion is arguably more important than a strong introduction. Take care to avoid just rephrasing your main points, and don't fall into the trap of repeating dry facts or citations.

You can provide a new perspective for your readers to think about or contextualize your research. Either way, make the conclusion vibrant and interesting, rather than a rote recitation of your research paper’s highlights.

Clichéd or generic phrasing

Your research paper conclusion should feel fresh and inspiring. Avoid generic phrases like "to sum up" or "in conclusion." These phrases tend to be overused, especially in an academic context and might turn your readers off.

The conclusion also isn't the time to introduce colloquial phrases or informal language. Retain a professional, confident tone consistent throughout your paper’s conclusion so it feels exciting and bold.

New data or evidence

While you should present strong data throughout your paper, the conclusion isn't the place to introduce new evidence. This is because readers are engaged in actively learning as they read through the body of your paper.

By the time they reach the conclusion, they will have formed an opinion one way or the other (hopefully in your favor!). Introducing new evidence in the conclusion will only serve to surprise or frustrate your reader.

Ignoring contradictory evidence

If your research reveals contradictory evidence, don't ignore it in the conclusion. This will damage your credibility as an expert and might even serve to highlight the contradictions.

Be as transparent as possible and admit to any shortcomings in your research, but don't dwell on them for too long.

Ambiguous or unclear resolutions

The point of a research paper conclusion is to provide closure and bring all your ideas together. You should wrap up any arguments you introduced in the paper and tie up any loose ends, while demonstrating why your research and data are strong.

Use direct language in your conclusion and avoid ambiguity. Even if some of the data and sources you cite are inconclusive or contradictory, note this in your conclusion to come across as confident and trustworthy.

• Examples of research paper conclusions

Your research paper should provide a compelling close to the paper as a whole, highlighting your research and hard work. While the conclusion should represent your unique style, these examples offer a starting point:

Ultimately, the data we examined all point to the same conclusion: Encouraging a good work-life balance improves employee productivity and benefits the company overall. The research suggests that when employees feel their personal lives are valued and respected by their employers, they are more likely to be productive when at work. In addition, company turnover tends to be reduced when employees have a balance between their personal and professional lives. While additional research is required to establish ways companies can support employees in creating a stronger work-life balance, it's clear the need is there.

Social media is a primary method of communication among young people. As we've seen in the data presented, most young people in high school use a variety of social media applications at least every hour, including Instagram and Facebook. While social media is an avenue for connection with peers, research increasingly suggests that social media use correlates with body image issues. Young girls with lower self-esteem tend to use social media more often than those who don't log onto social media apps every day. As new applications continue to gain popularity, and as more high school students are given smartphones, more research will be required to measure the effects of prolonged social media use.

What are the different kinds of research paper conclusions?

There are no formal types of research paper conclusions. Ultimately, the conclusion depends on the outline of your paper and the type of research you’re presenting. While some experts note that research papers can end with a new perspective or commentary, most papers should conclude with a combination of both. The most important aspect of a good research paper conclusion is that it accurately represents the body of the paper.

Can I present new arguments in my research paper conclusion?

Research paper conclusions are not the place to introduce new data or arguments. The body of your paper is where you should share research and insights, where the reader is actively absorbing the content. By the time a reader reaches the conclusion of the research paper, they should have formed their opinion. Introducing new arguments in the conclusion can take a reader by surprise, and not in a positive way. It might also serve to frustrate readers.

How long should a research paper conclusion be?

There's no set length for a research paper conclusion. However, it's a good idea not to run on too long, since conclusions are supposed to be succinct. A good rule of thumb is to keep your conclusion around 5 to 10 percent of the paper's total length. If your paper is 10 pages, try to keep your conclusion under one page.

What should I include in a research paper conclusion?

A good research paper conclusion should always include a sense of urgency, so the reader can see how and why the topic should matter to them. You can also note some recommended actions to help fix the problem and some obstacles they might encounter. A conclusion should also remind the reader of the thesis statement, along with the main points you covered in the paper. At the end of the conclusion, add a powerful closing statement that helps cement the paper in the mind of the reader.

How to Write a Conclusion for a Research Paper

Table of Contents

Writing a conclusion for a research paper is a critical step that often determines the overall impact and impression the paper leaves on the reader. While some may view the conclusion as a mere formality, it is actually an opportunity to wrap up the main points, provide closure, and leave a lasting impression. In this article, we will explore the importance of a well-crafted conclusion and discuss various tips and strategies to help you write an engaging and impactful conclusion for your research paper.

Introduction

Before delving into the specifics of writing a conclusion, it is important to understand why it is such a crucial component of a research paper. The conclusion serves to summarize the main points of the paper and reemphasize their significance. A well-written conclusion can leave the reader satisfied and inspired, while a poorly executed one may undermine the credibility of the entire paper. Therefore, it is essential to give careful thought and attention to crafting an effective conclusion.

When writing a research paper, the conclusion acts as the final destination for the reader. It is the point where all the information, arguments, and evidence presented throughout the paper converge. Just as a traveler reaches the end of a journey, the reader reaches the conclusion to find closure and a sense of fulfillment. This is why the conclusion should not be taken lightly; it is a critical opportunity to leave a lasting impact on the reader.

Moreover, the conclusion is not merely a repetition of the introduction or a summary of the main points. It goes beyond that by providing a deeper understanding of the research findings and their implications. It allows the writer to reflect on the significance of their work and its potential contributions to the field. By doing so, the conclusion elevates the research paper from a mere collection of facts to a thought-provoking piece of scholarship.

In the following sections, we will explore various strategies and techniques for crafting a compelling conclusion. By understanding the importance of the conclusion and learning how to write one effectively, you will be equipped to create impactful research papers.

Structuring the Conclusion

In order to create an effective conclusion, it is important to consider its structure. A well-structured conclusion should begin by restating the thesis statement and summarizing the main points of the paper. It should then move on to provide a concise synthesis of the key findings and arguments, highlighting their implications and relevance. Finally, the conclusion should end with a thought-provoking statement that leaves the reader with a lasting impression.

Additionally, using phrases like "this research demonstrates," "the findings show," or "it is clear that" can help to highlight the significance of your research and emphasize your main conclusions.

Tips for Writing an Engaging Conclusion

Writing an engaging conclusion requires careful consideration and attention to detail. Here are some tips to help you create an impactful conclusion for your research paper:

• Revisit the Introduction: Start your conclusion by referencing your introduction. Remind the reader of the research question or problem you initially posed and show how your research has addressed it.
• Summarize Your Main Points: Provide a concise summary of the main points and arguments presented in your paper. Be sure to restate your thesis statement and highlight the key findings.
• Offer a Fresh Perspective: Use the conclusion as an opportunity to provide a fresh perspective or offer insights that go beyond the main body of the paper. This will leave the reader with something new to consider.
• Leave a Lasting Impression: End your conclusion with a thought-provoking statement or a call to action. This will leave a lasting impression on the reader and encourage further exploration of the research topic.

Addressing Counter Arguments In Conclusion

While crafting your conclusion, you can address any potential counterarguments or limitations of your research. This will demonstrate that you have considered alternative perspectives and have taken them into account in your conclusions. By acknowledging potential counterarguments, you can strengthen the credibility and validity of your research. And by openly discussing limitations, you demonstrate transparency and honesty in your research process.

Language and Tone To Be Used In Conclusion

The language and tone of your conclusion play a crucial role in shaping the overall impression of your research paper. It is important to use clear and concise language that is appropriate for the academic context. Avoid using overly informal or colloquial language that may undermine the credibility of your research. Additionally, consider the tone of your conclusion – it should be professional, confident, and persuasive, while still maintaining a respectful and objective tone.

When it comes to the language used in your conclusion, precision is key. You want to ensure that your ideas are communicated effectively and that there is no room for misinterpretation. Using clear and concise language will not only make your conclusion easier to understand but will also demonstrate your command of the subject matter.

Furthermore, it is important to strike the right balance between formality and accessibility. While academic writing typically requires a more formal tone, you should still aim to make your conclusion accessible to a wider audience. This means avoiding jargon or technical terms that may confuse readers who are not familiar with the subject matter. Instead, opt for language that is clear and straightforward, allowing anyone to grasp the main points of your research.

Another aspect to consider is the tone of your conclusion. The tone should reflect the confidence you have in your research findings and the strength of your argument. By adopting a professional and confident tone, you are more likely to convince your readers of the validity and importance of your research. However, it is crucial to strike a balance and avoid sounding arrogant or dismissive of opposing viewpoints. Maintaining a respectful and objective tone will help you engage with your audience in a more persuasive manner.

Moreover, the tone of your conclusion should align with the overall tone of your research paper. Consistency in tone throughout your paper will create a cohesive and unified piece of writing.

Common Mistakes to Avoid While Writing a Conclusion

When writing a conclusion, there are several common mistakes that researchers often make. By being aware of these pitfalls, you can avoid them and create a more effective conclusion for your research paper. Some common mistakes include:

• Repeating the Introduction: A conclusion should not simply be a reworded version of the introduction. While it is important to revisit the main points, try to present them in a fresh and broader perspective, by foregrounding the implications/impacts of your research.
• Introducing New Information: The conclusion should not introduce any new information or arguments. Instead, it should focus on summarizing and synthesizing the main points presented in the paper.
• Being Vague or General: Avoid using vague or general statements in your conclusion. Instead, be specific and provide concrete examples or evidence to support your main points.
• Ending Abruptly: A conclusion should provide a sense of closure and completeness. Avoid ending your conclusion abruptly or leaving the reader with unanswered questions.

Editing and Revising the Conclusion

Just like the rest of your research paper, the conclusion should go through a thorough editing and revising process. This will help to ensure clarity, coherence, and impact in the conclusion. As you revise your conclusion, consider the following:

• Check for Consistency: Ensure that your conclusion aligns with the main body of the paper and does not introduce any new or contradictory information.
• Eliminate Redundancy: Remove any repetitive or redundant information in your conclusion. Instead, focus on presenting the key points in a concise and engaging manner.
• Proofread for Clarity: Read your conclusion aloud or ask someone else to read it to ensure that it is clear and understandable. Check for any grammatical or spelling errors that may distract the reader.
• Seek Feedback: Consider sharing your conclusion with peers or mentors to get their feedback and insights. This can help you strengthen your conclusion and make it more impactful.

How to Write Conclusion as a Call to Action

Finally, consider using your conclusion as a call to action. Encourage the reader to take further action, such as conducting additional research or considering the implications of your findings. By providing a clear call to action, you can inspire the reader to actively engage with your research and continue the conversation on the topic.

Adapting to Different Research Paper Types

It is important to adapt your conclusion approach based on the type of research paper you are writing. Different research paper types may require different strategies and approaches to writing the conclusion. For example, a scientific research paper may focus more on summarizing the key findings and implications, while a persuasive research paper may emphasize the call to action and the potential impact of the research. Tailor your conclusion to suit the specific goals and requirements of your research paper.

Final Thoughts

A well-crafted conclusion can leave a lasting impression on the reader and enhance the impact of your research. By following the tips and strategies outlined in this article, you can create an engaging and impactful conclusion that effectively summarizes your main points, addresses potential counterarguments, and leaves the reader with a sense of closure and inspiration. Embrace the importance of the conclusion and view it as an opportunity to showcase the significance and relevance of your research.

How to Write a Research Methodology for a Research Paper

Finishing a research paper feels great, but getting to the end—especially the conclusion—can be a bit tricky. 

People often wonder, "How do I wrap up my findings nicely?" or "What tone should I use in the conclusion?" 

If you're dealing with these questions, you're not alone! Many researchers find writing a good conclusion a bit challenging since it's a crucial part that is meant to leave a strong impression on your readers.

No need to worry! 

In this guide, we'll show you how to write a conclusion that not only ties up your research paper neatly but also leaves a strong impression. We'll cover everything from summarizing effectively to creating the right feeling. 

So, let’s get started. 

• 1. What is a Research Paper Conclusion?
• 2. How to Write a Research Paper Conclusion: 7 Steps
• 3. Research Paper Conclusion Examples
• 4. Things to Avoid While Writing the Research Paper Conclusion

What is a Research Paper Conclusion?

A research paper conclusion is like the final chapter of your paper. It's where you bring everything together and leave a lasting impression on your readers. 

In simple terms, it's the last part where you sum up what you found during your research and explain why it matters. 

The conclusion isn't just a summary; it's a chance to make your research memorable and show its importance.

Types of Research Paper Conclusions

When it comes to writing the conclusion of your research paper, there isn't a one-size-fits-all approach. Different types of research papers call for different types of conclusions. Here are some common types:

• Summarizing Conclusion

This type recaps the key points and findings of your research. It's like giving your readers a quick overview of what you discovered without introducing new information. Summarizing conclusions works well for straightforward research papers.

• Reflective Conclusion

A reflective conclusion allows you to share your personal thoughts on the research process, challenges faced, and lessons learned. It adds a human touch to your paper, giving readers insight into your journey as a researcher.

• Open-ended Conclusion

Some research papers benefit from an open-ended conclusion that leaves room for further exploration. This type invites readers to think critically, ask questions, or even conduct additional research on the same topic.

How to Write a Research Paper Conclusion: 7 Steps

Writing an effective conclusion for your research paper involves more than just summarizing your findings. Follow these six essential steps to ensure your conclusion leaves a lasting impact:

Step 1: Restate the Research Problem

Start wrapping up your paper by going back to the main research question or issue you were investigating. 

Remind your readers about what you were trying to find out or understand. This gives your conclusion a clear connection to the original goal of your research, helping readers see the bigger picture.

Step 2: Revisit Your Thesis Statement

Go back to the main idea or argument you had in your paper—this is called your thesis statement. Double-check that your conclusion matches and supports what you wanted to prove or talk about in the beginning. 

This step is important because it keeps your conclusion connected to the main point of your research, making everything fit together nicely.

Step 3: Summarize Key Points

Give a short and clear recap of the most important things you found in your research. Keep it simple and stick to what you've already talked about—don't bring in new details now. 

The goal is to remind your readers of the important stuff you covered earlier. This helps to underline why your research is important and what you want them to take away from it.

Step 4: Discuss the Implications

Address the broader implications of your research. Explain why your findings matter and how they contribute to the existing body of knowledge in your field. 

Discuss the practical applications of your research and highlight any potential areas for further exploration.

Step 5: Connect with the Introduction

Create a seamless connection between your conclusion and the introduction. Referencing key elements from the introduction helps to create a cohesive narrative for your paper. 

This connection gives your research a sense of completeness and unity.

Step 6: Consider the "So What?" Factor

Ask yourself the question, "So what?" Why should readers care about your research? Clearly articulate the significance of your findings and their relevance to the broader academic or real-world context. 

Demonstrating the impact of your research adds depth to your conclusion.

Step 7: End with a Strong Closing Statement:

Conclude your research paper with a memorable closing statement. This could be a thought-provoking reflection, a call to action, or a suggestion for future research.

A strong closing leaves a lasting impression on your readers and emphasizes the importance of your work.

Things to Avoid While Writing the Research Paper Conclusion

While crafting a conclusion for your research paper, it's crucial to steer clear of common pitfalls that can diminish the impact of your final remarks. 

Here are some things to avoid:

• Repetition: Avoid rehashing the exact language used in the introduction or body of your paper. A conclusion should summarize key points without duplicating content.
• Introducing New Information: Resist the temptation to introduce new ideas or data in the conclusion. This section is for summarizing existing content and reinforcing key findings.
• Overly Complex Language: Keep your conclusion clear and accessible. Avoid introducing overly complex or technical language that might confuse your readers.
• Lack of Connection to Introduction: Ensure that your conclusion ties back to the introduction. Failing to connect these sections can make your paper feel disjointed.
• Vague Statements: Steer clear of vague statements that lack substance. Clearly articulate the significance of your findings and their broader implications.
• Apologies or Excuses: Avoid including apologies or excuses for limitations in your research. While acknowledging limitations is important, the conclusion is not the place to dwell on them.
• New Arguments or Debates: The conclusion is not the space to introduce new debates or arguments. Keep the focus on summarizing your research and its implications.
• Abrupt Endings: A conclusion should not end abruptly. Instead, provide a thoughtful and well-rounded closing statement about the results of your study.

To sum it up, we've gone through important steps to make your research paper conclusion strong. We covered things like going back to your main question, talking about the most important points, and thinking about why your research matters in the real world.

Remember, a good ending is more than just a summary; it captures the heart of your research and answers the big "So what?" question. 

Remember, don't say the same things too much, don't add new details at the end, and keep your language simple!

Writing a decisive conclusion to your research paper might seem straightforward at first glance. But if you’ve never written one before, it can be quite tricky!

Many of us stare at that blank page, wondering, “How do I wrap this up neatly?”

But don’t worry! 

If you don’t know how to write a conclusion for a research paper, you can get expert advice from this guide. In this blog, we’ll discuss all the components that make up a great research paper conclusion.

With some examples, things to avoid, and valuable tips, you’ll understand what it takes to conclude your research paper successfully.

On this Page

What is a Research Paper Conclusion?

A research paper conclusion serves as one of the most critical parts of the paper. Why? Because: 

‘A conclusion in a research paper is like the grand finale of a fireworks show. It's where you bring all your ideas together, tie up loose ends, and leave your reader with a lasting impression.’

In general, a good conclusion provides:

• Closure: Provides a sense of closure to your paper
• Understanding: Ensures the reader comprehends the significance of your research
• Final Impression: It leaves the reader with a memorable last impression

Conclusions can also serve as the starting point for more research. They help generate new ideas to solve a problem you talked about in your paper or suggest different ways to look at a research topic.

What’s Included in a Research Paper Conclusion & How Long is it?

In the conclusion of a research paper, you bring everything together. Here's what you should include:

• Summarize Findings: Quickly recap the important research paper results or discoveries
• Explain Significance: Share why your findings matter in the bigger picture
• Address Limitations: Talk about any challenges or limitations in your study
• Suggest Future Research: Point out areas where more research could be done
• Reflect on the Process: Share thoughts on how the research journey went
• Revisit Main Points: Remind readers of your main arguments or questions

Typically, a conclusion can take the shape of a single paragraph. But, depending on the nature of the research paper, it can be divided into 2 or 3 paragraphs. 

Now, let’s look at the different types of conclusions that you can write for your research paper.

Types of Research Papers Conclusions

Depending on the type of research paper, the conclusion can take any of the following forms:

• Summary Conclusion: Recaps the main points and findings of your research
• Future Research Implications: Suggests avenues for further exploration and study
• Practical Applications: Discusses real-world applications of your research findings
• Reflection on the Research Process: Share insights gained during the research journey

The type you choose to adjust your conclusion to depends on the nature of your research. 

Let’s now jump to writing an effective conclusion for your research paper. 

Steps for Writing The Perfect Research Paper Conclusion

Follow the steps below and learn how to write a strong conclusion for a research paper that leaves a lasting impression.

Step 1. Restate the Problem Statement

The first and foremost part of a good conclusion is that it directly addresses the main problem statement of the research . Typically, wrapping this part up in a single sentence is enough. You don’t have to drag the sentence unnecessarily. 

Here is a great example of the original problem statement and the restated problem statement in the conclusion: 

Restated in the Conclusion: 

One thing to note is that you should avoid using the same wording you used in the initial problem statement . The problem stated in the conclusion should be different from the one you mentioned in the introduction. 

Step 2. Revisit your Thesis Statement

After the problem statement, you should write the main thesis of the research paper that you carried throughout the paper. After you’ve written the body of your paper with supporting evidence, you’ll have a better idea of the bigger picture. 

As a result, you’ll be able to reintroduce the statement in the conclusion in a better way. Also, don’t just paste the thesis statement from the beginning of the paper. 

Here is an effective example:

Original thesis:

Restated in the conclusion: 

Step 3. Summarize the Main Points

Summarizing your research paper's main points is essential, and here are some easy steps to take effectively:

Firstly, pick out the most important arguments and facts. Make sure they matter, and avoid saying the same things over and over. Keep it simple and focus on the key points that show why your research is significant.

Next, quickly go through the main arguments you wrote about in your paper. Shortly, state them and highlight how they all support your main idea.

If there were any opposing views you talked about, just mention them briefly. Remind the reader why your main point is still strong even if there are different opinions.

Lastly, don't bring in new stuff. Stick to what you already said. Remind the reader how solid your main points are without going into too much detail.

Here is an example:

Step 4. State the Importance and Significance of Your Ideas

After laying out the main points of your argument, it's time to highlight why these points matter. Once you've mentioned the key arguments, dive into why they are important. 

You can talk about how your ideas affect the real world or share research paper results that show why your discoveries are significant.

In the conclusion, write the most important things you learned—both practical and theoretical. You can suggest what people should do next or propose ideas for more research. This way, you finish your paper by showing why it all matters.

Step 5. Give your Conclusion a Closing Thought

To conclude your paper, consider leaving your readers with a compelling idea or a call to action.  End your paper with a thought that encourages more thinking about your argument and possibly answers any remaining questions from your paper's main points   Just as you've guided your readers through your research, providing a closing thought ensures they leave with something to think over or act upon. 

Here is an example: 

You can summarize your paper into a well-written conclusion by keenly following the steps above. 

Here is the complete conclusion we’ve extracted from the steps above: 

Something to note here is that in an argumentative research paper’s conclusion, you have to summarize your key arguments briefly. But, in an empirical research paper, you have to summarize your key findings and results of your studies.

Argumentative Conclusion Example

Take a look at this example of an argumentative research paper conclusion. 

Empirical Conclusion Example

Here is a good example of an empirical research paper conclusion. 

What You Should Avoid in Your Conclusion?

Now that you know how to write a conclusion for a research paper, you should also keep note of what to avoid. 

Avoid Generic or Cliché Phrases

Refrain from starting your conclusion with statements like:

• In conclusion…
• In summary…
• To conclude…
• To summarize…
• To wrap up…
• To sum it up…
• In closing…

These phrases are redundant and don’t follow a professional tone in the context of a research paper. 

Don’t add new information

Don't introduce brand-new info in your conclusion. Always stick to summarizing what you've already talked about in the research paper. Adding new information will confuse the readers, and they’ll be unsure what point you are actually trying to make. 

There is no need to add new arguments in the conclusion. 

Keep it Simple and Concise

Skip the use of fancy language, and don’t unnecessarily complicate your conclusion. Keep it simple and to the point. Use clear and straightforward expressions to make sure your message is easily understood by all readers.

Also, try to make your conclusion concise and keep the word limit in check. You shouldn’t address your research methods, as it will make the conclusion prolonged and lengthy.

Don’t State the Weaknesses of Your Research

It is a fact that every research has its fair share of drawbacks and weaknesses. If you have any doubts regarding your research paper, just state the limitations in a neutral tone. Focus on the strong points as much as you can. 

Avoid Empty Phrases

Cut out vague phrases that don't really say much. Every sentence should add value and show why your research matters.

Don't be Too Ambitious

Avoid making your findings sound like they solve all the world's problems. You shouldn’t make big promises about what your research will do in the future. Be careful about setting the expectations.

Now, taking a look at some research paper conclusion examples will help you out. Read on!

How to write a conclusion for a research paper

Research paper conclusions provide closure for your paper—but they can be difficult to write. What should you include? In this post, we discuss how to write a conclusion for a research paper.

What is a conclusion?

The conclusion to a research paper sums of your main argument and provides closure for your reader. It will return to your thesis statement and revisit the ways that you proved it.

The content and format of your conclusion will ultimately differ depending on the subject of your paper. Some fields have more specific expectations for what needs to be included.

You should always check your assignment’s guidelines or rubric to ensure that you understand what your instructor expects in a research paper conclusion.

How to write a conclusion

In this section, we break down the main parts of a conclusion and provide tips on how to approach each one.

The opening of a conclusion

The point of a conclusion’s opening statement is to transition from the main body of your paper to the concluding section. Some types of research papers include section headers that label each part of the paper. In these cases, your reader will be able to clearly see that you’re about to conclude.

In most other cases, begin your conclusion with a signal that indicates that you’re moving into the concluding section of your paper. For instance, you might start your conclusion by stating “in conclusion,” “to conclude,” or “in sum.”

What you can include in a conclusion

Although you shouldn’t include any new data or evidence in a conclusion, you can include suggestions for further research, insights about how your research could be applied in different contexts, or a course of action.

The bulk of the conclusion should synthesize—not summarize—the main points of your paper. If your introduction included historical information or an anecdote, return to that information now.

Your conclusion should also answer the “so what” question: why is this research relevant? Who should care about your argument and why?

The ending of a conclusion

Finally, you’ll want to end your conclusion with a closing statement that wraps up your concluding section (and your paper as a whole).

Tips for writing a conclusion

1. don’t include new data or evidence.

Your conclusion should provide closure to your paper, so introducing new information is not appropriate and will likely confuse your reader.

2. Don’t simply restate your thesis

You should never simply copy and paste your thesis statement into your conclusion. Instead, revisit your thesis in light of the evidence and analysis that you put forth in the main body of your paper.

3. Provide closure for your reader

A strong conclusion provides closure for the reader by synthesizing the main points of the paper and putting to rest any questions that the reader may have during the process of reading. The best way to test if your conclusion provides closure is to ask someone to read your paper.

4. Make suggestions for further research

While conclusions should not introduce new data or arguments, they can include suggestions for further research. A single research paper never covers everything—there are always possible new angles and approaches.

Next steps for a successful research paper

Once you’ve written your conclusion, you should review what you’ve written and make revisions, as needed. Then, double-check that you’ve cited all borrowed material and that your paper has a bibliography with accurate citations.

Use BibGuru’s citation generator to quickly create accurate citations for the books, articles, websites, and other sources that you used in your research paper.

Frequently Asked Questions about how to write a conclusion for a research paper

A conclusion contains an opening statement (often a restatement of the thesis), recommendations for further studies or applications, and a closing statement.

Start by signaling to the reader that you are moving into the concluding section.

The length of your conclusion will depend on the length of your paper. Most research paper conclusions will be around 1-2 paragraphs.

End your conclusion with a closing statement that wraps up the paper and provides closure to your reader.

Writing a Paper: Conclusions

Writing a conclusion.

A conclusion is an important part of the paper; it provides closure for the reader while reminding the reader of the contents and importance of the paper. It accomplishes this by stepping back from the specifics in order to view the bigger picture of the document. In other words, it is reminding the reader of the main argument. For most course papers, it is usually one paragraph that simply and succinctly restates the main ideas and arguments, pulling everything together to help clarify the thesis of the paper. A conclusion does not introduce new ideas; instead, it should clarify the intent and importance of the paper. It can also suggest possible future research on the topic.

An Easy Checklist for Writing a Conclusion

It is important to remind the reader of the thesis of the paper so he is reminded of the argument and solutions you proposed.

Think of the main points as puzzle pieces, and the conclusion is where they all fit together to create a bigger picture. The reader should walk away with the bigger picture in mind.

Make sure that the paper places its findings in the context of real social change.

Make sure the reader has a distinct sense that the paper has come to an end. It is important to not leave the reader hanging. (You don’t want her to have flip-the-page syndrome, where the reader turns the page, expecting the paper to continue. The paper should naturally come to an end.)

No new ideas should be introduced in the conclusion. It is simply a review of the material that is already present in the paper. The only new idea would be the suggesting of a direction for future research.

Conclusion Example

As addressed in my analysis of recent research, the advantages of a later starting time for high school students significantly outweigh the disadvantages. A later starting time would allow teens more time to sleep--something that is important for their physical and mental health--and ultimately improve their academic performance and behavior. The added transportation costs that result from this change can be absorbed through energy savings. The beneficial effects on the students’ academic performance and behavior validate this decision, but its effect on student motivation is still unknown. I would encourage an in-depth look at the reactions of students to such a change. This sort of study would help determine the actual effects of a later start time on the time management and sleep habits of students.

This resource outlines the generally accepted structure for introductions, body paragraphs, and conclusions in an academic argument paper. Keep in mind that this resource contains guidelines and not strict rules about organization. Your structure needs to be flexible enough to meet the requirements of your purpose and audience.

Conclusions wrap up what you have been discussing in your paper. After moving from general to specific information in the introduction and body paragraphs, your conclusion should begin pulling back into more general information that restates the main points of your argument. Conclusions may also call for action or overview future possible research. The following outline may help you conclude your paper:

In a general way,

• Restate your topic and why it is important,
• Restate your thesis/claim,
• Address opposing viewpoints and explain why readers should align with your position,
• Call for action or overview future research possibilities.

Remember that once you accomplish these tasks, unless otherwise directed by your instructor, you are finished. Done. Complete. Don't try to bring in new points or end with a whiz bang(!) conclusion or try to solve world hunger in the final sentence of your conclusion. Simplicity is best for a clear, convincing message.

The preacher's maxim is one of the most effective formulas to follow for argument papers:

Tell what you're going to tell them (introduction).

Tell them (body).

Tell them what you told them (conclusion).

How to Write a Conclusion for a Research Paper that Resonates

The conclusion of a research paper is a crucial part of the entire document. The final section summarizes the main points, restates the thesis statement, and provides closure to the reader. Writing a strong conclusion for a research paper can be challenging because you must bring together all the ideas you’ve presented concisely and compellingly. Don’t fret, as we’ll let you know how to write a conclusion for a research paper like a professional  paper writing service  provider. So, let’s dive in!

The Ultimate Guide on How to Write a Conclusion for a Research Paper

A great conclusion makes your paper stand out and leaves a lasting impression on your readers. Let us help you figure out how to write a killer conclusion for your research paper.

Four Important Elements of a Research Paper Conclusion

These are the essential elements you must include in the conclusion of your  research paper writing  for a lasting impression.

Restate the Thesis Statement

It’s really important to remind readers of the main argument in your paper. You should state the  thesis statement  in the intro and then again in the conclusion. But don’t just copy and paste the same words! It’s better to rephrase it in a slightly different way so readers know you understand the topic.

Summarize the Main Points of the Research Paper

It’s important to sum up the paper’s main points to show the reader it’s covered the topic well. Just use the topic sentences from the body paragraphs and make it brief; that should do it.

Discuss the Implications of the Research

It’s important to cover the implications of the research so the reader can understand the bigger picture. This part should emphasize the real-world or theoretical implications of the research and explain why the results are important. These implications can involve multiple topics, such as policy, practices, theories, or further research.

Provide Closure to the Reader

A satisfying research paper conclusion is the key to its success. This last section should link together the main points made throughout the paper and make the reader feel like the paper has come to its natural conclusion. It’s a great idea to finish the conclusion with a thought-provoking statement, an invitation to take action or a question that will leave the reader pondering.

For Example:

Tips for Writing A Strong Conclusion

These are the expert tips to help you write a strong conclusion for your research paper:

Tip 1: Keep it Concise and to The Point

Make sure your conclusion is short and sweet, summing up the main points of your research paper without adding anything new. Don’t use different words or phrases to fill up space – say what needs to be said in a simple, straightforward way.

Tip 2: Use language that is clear and easy to understand

Make sure everyone easily understands your conclusion. Don’t use technical words. Stick to the main points and make sure everyone can follow along.

Tip 3: Avoid Introducing New Information

Your conclusion should wrap up the ideas you’ve presented in your paper, not add anything new. Summarize the main ideas and arguments that you’ve presented and show how they back up your thesis.

Tip 4: Use a Strong Concluding Sentence

Wrapping up your paper with a strong conclusion helps tie everything together and leaves an impact on the reader. Why not finish with a thought-provoking question, a call to action or a powerful statement? It’ll be sure to stick with them.

Common Mistakes to Avoid

Here are some common mistakes you should avoid when writing a conclusion for your research paper:

Don’t Repeat the Information

In your research paper conclusion, try not to copy what’s already been said in the body of the paper. Sum up the main points, but don’t just repeat them word for word. Show how the evidence and ideas in the paper back up the thesis.

Avoid Including Personal Opinions and or Biases

Be careful not to let your feelings sneak into the conclusion. Stick to the facts and sum up the main points of your paper instead of giving your own opinion. Keep it objective!

Don’t Use Weak Language or Cliches:

Don’t use weak language or cliches like “in conclusion” or “it can be said that.” Also, don’t say “more research is needed” since it makes your conclusion seem unfulfilled. Instead, be clear about when and where you’re talking about and emphasize the importance of your research.

Example of Good Research Paper Conclusions

It’s important to make a lasting impression on your reader, so having a good conclusion to your research paper is key. Here are some examples of what makes a strong conclusion and the elements that make it effective:

Example 1 – A Research Paper on The Effects of Social Media on Mental Health:

Through the research analysis, it is clear that social media use can significantly negatively affect mental health. To address this issue, individuals and society need to recognize social media’s impact and take steps to mitigate its negative effects. This research highlights the need for further investigation into the relationship between social media and mental health, as well as the development of strategies to promote healthy social media use.

Example 2 – A Research Paper on The Benefits of Exercise:

The findings of this study demonstrate the numerous benefits of regular exercise, including improved cardiovascular health, increased strength, and reduced stress levels. These benefits highlight the importance of physical activity for individuals of all ages and abilities. Individuals and society need to prioritize exercise and promote physical activity to improve overall health and well-being.

Finishing your research paper with a strong conclusion is key to leaving a lasting impact on your reader. We are summarizing the conclusion for a research paper in brief points.

•  Sum up the main points of your paper and restate your thesis statement.
• Think about the implications of your research and provide closure for your reader.
• Keep your language clear and avoid introducing new info.
• Use a strong conclusion sentence, and don’t make mistakes like repeating yourself or adding personal opinions or bias.

How Quickly Do Prices Respond to Monetary Policy?

Download PDF (238 KB)

FRBSF Economic Letter 2024-10 | April 8, 2024

With inflation still above the Federal Reserve’s 2% objective, there is renewed interest in understanding how quickly federal funds rate hikes typically affect inflation. Beyond monetary policy’s well-known lagged effect on the economy overall, new analysis highlights that not all prices respond with the same strength or speed. Results suggest that inflation for the most responsive categories of goods and services has come down substantially from recent highs, likely due in part to more restrictive monetary policy. As a result, the contributions of these categories to overall inflation have fallen.

Monetary policy affects inflation with a lag. This means that, although interest rates react quickly when the Federal Reserve raises the federal funds rate, the effects on inflation are slower and indirect. Higher interest rates increase borrowing costs, slowing investment and overall demand, which ultimately eases the pressure on prices. Understanding the timing and strength of this mechanism is key for policymakers.

Many researchers have estimated the speed and strength of the economy’s response to monetary policy, notably Romer and Romer (2004). The focus is typically a broader measure of inflation, such as headline or core, which reflects an average across many goods and services. However, not all prices of the component goods and services react to monetary policy in the same way. For example, food and energy prices, which are excluded from core but included in headline inflation, often move more in response to global market fluctuations, such as changes in international oil prices, rather than to changes in domestic monetary policy.

In this Economic Letter , we estimate how prices of different goods and services respond to changes in the federal funds rate and use those estimates to build a monetary policy-responsive inflation index. We find substantial variation in how prices react to monetary policy, which suggests that understanding the makeup of overall inflation can provide insights into the transmission of monetary policy to inflation. The extent to which categories that are more responsive to the federal funds rate contribute to inflation affects how much slowing in economic activity is needed to reduce overall inflation. Our analysis indicates that recent ups and downs of inflation have been focused in categories that are most sensitive to monetary policy. Inflation rates for the most sensitive categories—and their contributions to headline inflation—rose from the first half of 2020 through mid-2022, reaching a higher peak than headline inflation, and then began to decline. The inflation rate for this most responsive group of goods and services categories is now close to its pre-2020 rate. Our findings suggest that the Fed’s rate hikes that began in March 2022 are exerting downward pressure on prices and will continue to do so in the near term. Our estimated lags are consistent with the view that the full effects of past policy tightening are still working their way through the economy.

Measuring how prices react to monetary policy

To understand which goods and services are most responsive to monetary policy, we need to determine how their prices react to changes in the federal funds rate, the Federal Reserve’s main policy rate. Because the Federal Reserve adjusts the federal funds rate target in response to macroeconomic developments, including inflation, we use a transformation of the federal funds rate in our estimation. This transformed series, developed by Romer and Romer (2004) and updated by Wieland and Yang (2020), captures the differences between Federal Reserve staff forecasts and the chosen target rate, leaving only policy shocks, or movements in the federal funds rate that are not driven by actual or anticipated changes in economic conditions. We use this series as a so-called instrument for the federal funds rate, such that our results can account for how the federal funds rate itself, rather than its transformation, affects inflation.

We use an approach developed by Jordà (2005) that compares two forecasts—with and without rate shocks—to estimate how the federal funds rate affects price movements over time. Specifically, we estimate the relationship between the federal funds rate and the cumulative percent change in prices, controlling for recent trends in the federal funds rate, inflation, and economic activity. Repeating this estimation over multiple horizons produces a forecast comparison, or impulse response function, that gives us an estimate of the expected percent change in prices following a rate increase. For example, applying this method to the headline personal consumption expenditures (PCE) price index indicates that four years after a 1 percentage point increase in the federal funds rate, overall prices are typically about 2.5% below what they would have been without the rate increase.

Creating a policy-responsive inflation index

We estimate impulse response functions separately for the 136 goods and services categories that collectively make up headline PCE inflation. Figure 1 shows examples of the largest cumulative percent price declines over a four-year period in response to a 1 percentage point increase in the federal funds rate. The goods and services categories selected as examples account for large shares of total expenditures in headline PCE inflation. We also include one example of the few categories where prices do not decline, higher education, shown as a small positive value.

Figure 1 Reaction to a policy rate increase: Selected PCE categories

The takeaway from Figure 1 is that headline PCE inflation is made up of categories that differ in their responsiveness to increases in the federal funds rate. Some respond more strongly, such as those with larger typical cumulative price declines, while others respond less strongly, such as those with smaller typical price declines. Focusing on the most responsive categories can shed light on how monetary policy has influenced the path of inflation over the post-pandemic period. We use our results to divide the categories into two groups of goods and services. The most responsive group (blue bars) contains goods and services whose largest cumulative percent price decline over a four-year window is in the top 50% of all such declines. The least responsive group (red bars) contains goods and services in the bottom 50%.

Following the methods in Shapiro (2022), we use these two groups, along with the share of total expenditures for each good or service, to create two new aggregate PCE inflation measures. Figure 2 shows their 12-month percent changes over time. The blue shading marks the period from mid-2019 until early 2020 when the Federal Reserve lowered the federal funds rate. The vertical yellow line marks the start of the most recent tightening cycle in March 2022. Inflation in the most responsive categories (blue line) is more volatile than overall headline PCE inflation (green line) from the Bureau of Economic Analysis (BEA), and inflation in the least responsive categories is less volatile (red line).

Figure 2 Most and least responsive inflation rates

After the start of the 2020 recession, inflation rates for both categories rose but have since come down from their recent peaks. This pattern is particularly pronounced for the most responsive inflation group, for which inflation peaked at 10.5% in mid-2022 and has fallen to 0.9% as of January 2024; this is just under its average of 1% from 2012, when the Federal Reserve officially adopted a numerical inflation objective, to 2019. Inflation in the least responsive group peaked later, in early 2023, and has fallen only slightly to 3.8% as of January 2024; it remains well above its 2012–2019 average of 1.8%.

How does policy-responsive inflation react to rate increases?

The inflation rates of categories in the most and least responsive groups can move for reasons beyond changes in the federal funds rate, such as global or national macroeconomic developments. To assess the specific role of policy rate increases, we use the methodology described earlier to estimate how the most and least responsive inflation groups tend to react to rate hikes.

The results in Figure 3 suggest that an increase in the federal funds rate typically starts exerting downward pressure on the most responsive prices after about 18 months, when the line showing the impulse response function falls below zero. Month-to-month price changes start falling after a little over a year, depicted when the slope drops below zero and stays negative. This is quicker than the response of overall headline prices from the BEA (not shown), which becomes negative after a little over 24 months and shows month-to-month declines after about 18 months.

Figure 3 Reaction of most and least responsive prices to rate hikes

Because we grouped inflation categories based on the size of their response, there is not necessarily a tie-in to the speed of each categories’ change. However, our results suggest that looking at the most responsive goods and services may also be a useful way of assessing how quickly monetary policy affects inflation.

Applying the typical impact timing of the most responsive group of goods and services to the most recent tightening cycle, shown by the federal funds rate line in Figure 4, leads to several conclusions. First, rate cuts from 2019 to early 2020 could have contributed upward price pressures starting in mid- to late 2020 and thus could explain some of the rise in inflation over this period. Second, the tightening cycle that began in March 2022 likely started putting downward pressure on prices in mid-2023 and will continue to do so in the near term. This is consistent with the view that the full effects of monetary policy tightening have yet to be felt. Finally, though inflation for the most responsive categories has been falling since mid-2022, the early part of this decline was likely to have been driven more by changes in prevailing economic conditions than by policy tightening, given estimated policy lags. Some research has considered whether policy lags have shortened (see, for example, Doh and Foerster 2021); however, because inflation began falling mere months after the first rate hike, the drop in inflation may have been too soon to be caused by policy action.

Figure 4 Headline inflation contributions and the federal funds rate

Our findings in this Letter are useful for broadening our understanding of how monetary policy affects inflation. For example, if inflation and the contributions to overall headline inflation are high in a set of categories that are more responsive to monetary policy, as was the case in early 2022, then rate hikes during the most recent tightening cycle are likely to continue to reduce inflation due to policy lags. On the other hand, though inflation in the least responsive categories may come down because of other economic forces, less inflation is currently coming from categories that are most responsive to monetary policy, perhaps limiting policy impacts going forward.

Several phase II studies have demonstrated that psilocybin-assisted therapy shows therapeutic potential across a spectrum of neuropsychiatric conditions, including major depressive disorder (MDD). However, the mechanisms underlying its often persisting beneficial effects remain unclear. Observational research suggests that improvements in psychological flexibility may mediate therapeutic effects. However, no psychedelic trials to date have substantiated this finding in a clinical sample. In an exploratory placebo-controlled, within-subject, fixed-order study, individuals with moderate to severe MDD were administered placebo (n = 19) followed by psilocybin (0.3 mg/kg) (n = 15) 4 weeks later. Dosing sessions were embedded within a manualized psychotherapy that incorporated principles of Acceptance and Commitment Therapy. Depression severity, psychological flexibility, mindfulness, and values-congruent living were measured over a 16-weeks study period. Psychological flexibility, several facets of mindfulness, and values-congruent living significantly improved following psilocybin and were maintained through week 16. Additionally, improvements in psychological flexibility and experiential acceptance were strongly associated with reductions in depression severity following psilocybin. These findings support the theoretical premise of integrating psilocybin treatment with psychotherapeutic platforms that target psychological flexibility and add to emerging evidence that increasing psychological flexibility may be an important putative mechanism of change in psilocybin-assisted therapy for MDD and potentially, other mental health conditions.

Introduction

In recent years, there has been a revitalization of interest in the therapeutic potential of psychedelic substances for a variety of neuropsychiatric and behavioral health conditions 1 , 2 . Psilocybin, a naturally occurring alkaloid found in the Psilocybe genus of mushrooms, is categorized as a “classical psychedelic” compound along with lysergic acid diethylamide (LSD), dimethyltryptamine (DMT), and others. These drugs produce a range of acute perceptual and mood alterations in humans presumably through agonism of brain serotonin 5HT-2A receptors 3 , 4 .

In the past decade, a number of early phase trials have suggested that psilocybin-assisted therapy (i.e., embedding psilocybin dosing sessions within a framework of psychological support or psychotherapy) may have rapid acting and persisting therapeutic effects across a number of mental health conditions, including depression, anxiety, and substance use disorders 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 . These beneficial effects have been reported after just one or two doses of psilocybin, and in some cases, may persist up to 1–4.5 years post-administration 15 , 16 .

However, the mechanisms by which psilocybin-assisted therapy may produce both rapid and sustained antidepressant effects remain unclear. A number of neurobiological, psychological, cognitive/behavioral and spiritual mechanisms have been proposed to explain psilocybin-assisted therapy’s rapid and sustained antidepressant effects. For instance, certain psilocybin treatment studies have found that positive clinical outcomes were correlated with or partially-mediated by mystical-type subjective experiences 12 , 13 , 14 , 17 , 18 or alterations in neuroplasticity 19 . Other potential psychological and cognitive/behavioral mechanisms include increased psychological flexibility and experiential acceptance 20 , 21 , 22 , increased connectedness 23 , 24 , relaxation and revision of high-level beliefs 25 , 26 , and emotional breakthrough 27 .

Given that multiple potential mechanisms may contribute to the therapeutic effects of psilocybin-assisted therapy, it remains unclear which psychotherapeutic models and approaches are optimal. Some studies have employed non-specific supportive psychotherapeutic models while others have incorporated elements of evidence-based, condition-specific therapies. In developing a therapeutic approach for an exploratory clinical trial of psilocybin-assisted therapy for major depression, our group sought an evidence-based therapy that would be synergistic with the subjective effects of psilocybin and offer a structure for the preparation and integration psychotherapy sessions. After evaluating a range of potential therapies, we selected Acceptance and Commitment Therapy (ACT) given conceptual and phenomenological overlaps between ACT and psilocybin-assisted therapy 20 .

Within Acceptance and Commitment Therapy, psychological flexibility is conceptualized as the central organizing principle underlying mental well-being and therapeutic change 28 . Psychological flexibility is a multifaceted construct composed of: (a) openness to experience (experiential acceptance); (b) behavioral awareness (i.e., mindful attention to the present moment); and (c) values-driven action 29 . In line with this model, global psychological inflexibility and several of its subcomponents (most notably experiential avoidance) have been linked with depression severity (for reviews, see 30 , 31 ) and improvement in these measures linked with clinical improvement following ACT 32 , 33 , 34 , 35 .

Psychedelics and psychological flexibility

A growing body of research suggests that psychedelic therapy may increase psychological flexibility and lead to therapeutic benefits via these changes. Several cross-sectional and observational studies have found that use of a classic psychedelic is associated with subsequent increases in psychological flexibility 21 , 36 , 37 , 38 . Furthermore, following classic psychedelic use, increases in psychological flexibility have been found to be associated with improvements in mental health, including depressive symptoms 22 , 36 , anxious/depressive symptoms 21 , positive and negative affect 37 , and grief 38 . These findings suggest that psychological flexibility may be a transdiagnostic mechanism contributing to the positive effects of psychedelics. Importantly, research has not yet examined the effect of psilocybin-assisted therapy on psychological flexibility (or the effect of any psychedelic on psychological flexibility) within a clinical sample. Furthermore, no clinical trials to date have examined the association between increases in psychological flexibility and improvements in depressive symptoms following psilocybin-assisted therapy.

Mindfulness (defined as awareness and acceptance of one’s inner experiences) 39 is closely related to several components of psychological flexibility, including behavioral awareness and experiential acceptance 29 , 40 . In a sample with MDD, a recent randomized controlled trial found that, relative to escitalopram, psilocybin-assisted therapy led to greater increases in experiential acceptance 5 . Furthermore, within this trial, increases in experiential acceptance following psilocybin-assisted therapy predicted improvements in depression severity, anxiety, suicidal ideation, and well-being 41 . Within non-clinical samples, several studies have observed increases in facets of mindfulness (most consistently the facets of experiential acceptance/non-judgmental awareness) following use/administration of classic psychedelics 22 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , including psilocybin 50 , 51 , 52 (for a review, see 53 ). Furthermore, in observational studies, increases in non-judgment of inner experience (closely related to experiential acceptance) following psilocybin were associated with reductions in anxiety 50 . However, no clinical trials have examined the effect of psilocybin-assisted therapy on mindfulness or its association with treatment outcomes.

Several naturalistic studies have found that classic psychedelic use is associated with changes in values. Among individuals that reported decreases in smoking following classic psychedelic use, participants attributed changes in life priorities/values as the primary psychological factor that contributed to this behavior change 54 . Research has also found that administration of psilocybin alongside support for spiritual practice is associated with increases in valuing of tradition 55 . However, the effect of classic psychedelics on values has not yet been examined in the context of a psychedelic clinical trial or within a clinical sample.

In sum, psychological flexibility is a promising putative transdiagnostic mechanism underlying psychotherapeutic interventions and potentially, the beneficial effects of psychedelic therapy. However, to date, research has not examined the effect of psilocybin-assisted therapy on (a) psychological flexibility; (b) mindfulness; or (c) values within a clinical trial. Furthermore, clinical research has not yet examined whether psilocybin-assisted therapy leads to improvements in depression severity via its effects on psychological flexibility. Finally, research has not yet evaluated the effect of psilocybin on psychological flexibility when psilocybin is combined with a therapeutic intervention specifically designed to increase psychological flexibility. Therefore, using data from a recent clinical trial of psilocybin-assisted therapy that used ACT as a therapeutic frame (for primary clinical outcomes, see 11 ), we examined (1) the effects of psilocybin-assisted therapy on (a) psychological flexibility/experiential acceptance, (b) mindfulness, and (c) values-congruent living, as well as (2) the association between changes in psychological flexibility/experiential acceptance and reductions in depression severity.

This study was conducted with approvals from the Institutional Review Boards of the VA Connecticut Healthcare System and Yale University, under a US Food and Drug Administration-approved Investigational New Drug application (D’Souza# IND #124,874), under a schedule 1 license from the US Drug Enforcement Agency (DEA) and was registered on clinicaltrials.gov on 13/06/2018 (NCT03554174). The authors assert that all procedures contributing to this work comply with the ethical standards of the relevant national and institutional committees on human experimentation and with the Helsinki Declaration of 1975, as revised in 2008.

Study design

The parent study from which the data presented here was derived utilized a placebo-controlled, within-subject, fixed-order design with enhanced blinding procedures. This study was designed primarily to investigate psilocybin’s effects on an electrophysiological biomarker of neuroplasticity (see 19 ), rather than to demonstrate changes in clinical or behavioral outcomes. The within-subject design was selected to increase the statistical power of the study and maximize feasibility, as each participant serves as their own control. Given that psilocybin can produce strong acute subjective and long-lasting antidepressant effects, the study had a fixed-order design of placebo first, followed by psilocybin, in order to limit functional unblinding and minimize potential carryover effects. The two dosing sessions were conducted approximately four weeks apart and were embedded within an eight-session psychotherapy protocol (see Fig.  1 for study design). Participants were assessed for a total of 16 weeks. For a full discussion of blinding procedures, the psychotherapy protocol, and outcomes related to depression, anxiety and quality of life, see 11 .

Study design and flow.

Study participants

Inclusion criteria included: (1) 18–65 years old; (2) Meet DSM-5 criteria for Major Depressive Disorder (MDD) by Structured Clinical Interview for DSM-5 (SCID-5-CT) 56 ; (3) current moderate to severe major depressive episode of at least six weeks duration prior to screening, defined by a score ≥ 17 on the GRID-HAM-D-17 57 , 58 ; (4) failed at least one adequate antidepressant trial (at least 6 weeks on a therapeutic dose) during the current depressive episode. Since medications commonly used in this population (e.g., serotonergic antidepressants) can interfere with the effects of psilocybin 59 , participants were required to be off any conventional antidepressant or antipsychotic medications for at least 2 weeks prior to study enrollment (or four weeks for fluoxetine). Exclusion criteria included: (1) primary psychiatric diagnosis other than MDD; (2) active substance use disorders; (3) past personal or family history of psychotic or bipolar disorder; (4) significant or unstable medical or neurological disease; (5) psilocybin exposure within the past year. For detailed inclusion/exclusion criteria see 11 .

Recruitment and screening procedures

Participants were recruited primarily through online postings, including clinicaltrials.gov, clinician referrals and word of mouth. Interested candidates were prescreened by telephone and if eligible, underwent an in-depth screening process. This included a structured psychiatric assessment (SCID-5-CT), psychiatric history and evaluation, and medical screening. Informed consent was obtained from all study participants. Recruitment began in fall of 2018 and concluded in spring 2021.

Interventions

All dosing sessions were conducted at the VA Connecticut Healthcare System, West Haven, CT, USA. At the first dosing session, participants received placebo (microcrystalline cellulose) in an opaque capsule, while during the second session they received an identical capsule containing psilocybin (0.3 mg/kg, maximum dose 35 mg). While lower than the 30 mg/70 kg protocol for which safety has been demonstrated, this dose is sufficient for producing psychedelic effects 60 . Psilocybin was obtained from the University of Wisconsin and the Usona Institute. For detailed descriptions of drug administration sessions and procedures used to enhance blinding and minimize expectancy effects, see 11 .

Psychotherapeutic support

Participants were assigned a study therapist and psychiatrist for the entire duration of the study. An equivalent number and type of therapy sessions were provided before and after each of the two dosing sessions during the period of primary outcome collection (through week 6): A two-hour long preparatory psychotherapy/psychoeducation session preceded each dosing session, while two one-hour long debriefing/integration psychotherapy sessions were conducted 1 day and 1 week after each dosing session. Following collection of the final primary outcome measures at week 6, participants had two additional integration sessions to help sustain any initial clinical improvements. A delineated therapeutic framework and therapy manual was used to improve consistency in therapeutic approach across participants and between study therapists. This therapy protocol incorporated principles and elements of Acceptance and Commitment Therapy (ACT) (see 11 for complete therapy manual). The rationale for including a specific psychotherapy and selecting ACT, the basic structure of the treatment model, and limitations to this approach, are described in detail separately 20 .

Outcome measures

Psychological flexibility was assessed using the Acceptance and Action Questionnaire-II (AAQ-II) 61 . Mindfulness was assessed using the Kentucky Inventory of Mindfulness Skills (KIMS) 62 , which includes the following scales: (a) Observe; (b) Describe; (c) Awareness; and (d) Accept Without Judgment. The degree to which participants are living in accordance with their values (values-congruent living) was measured with the Valued Living Questionnaire (VLQ) 63 . The AAQ-II, KIMS and VLQ were collected at baseline, week 2 (2 weeks after placebo), week 6 (2 weeks after psilocybin), and week 16 (3 months after psilocybin). Depression symptoms were assessed using the Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR-16) 64 , which was collected throughout the study, from baseline (day before placebo) through week 16. Adverse events were monitored and recorded throughout the trial. Vital signs were monitored throughout each dosing session. For safety data along with other clinical and subjective measures collected, see 11 .

Statistical analysis

The parent study from which data presented here was derived was powered primarily to investigate an electrophysiological biomarker of neuroplasticity rather than to demonstrate changes in clinical or behavioral outcomes. Data analysis was conducted on participants who completed at least one dosing session (ITT population). Data was analyzed using linear mixed models. Analysis of clinical outcomes through week 16 utilized time as a within-subjects factor. In order to explore the relationship between changes in depressive symptoms (QIDS-SR-16) and both (a) psychological flexibility (AAQ-II) and (b) Accept Without Judgment (KIMS), we conducted Spearman correlations between changes in these variables from before to 2 weeks after each dose. While the parent study also measured depression symptoms using the GRID-HAM-D-17, correlations in this substudy used the QIDS-SR-16 due to more available data points. Given the exploratory nature of the study and small sample size, all statistical tests were conducted using a two-tailed alpha threshold of 0.05, with no adjustments for multiple testing. All tests were performed using SAS, version 9.4 (SAS Institute Inc).

Of 949 individuals assessed for eligibility, 42 (4.4%) were screened in-person, and 22 (2.3%) were ultimately enrolled. 19 participants completed at least one dosing session, of which 15 completed both dosing sessions. Participant demographics and baseline clinical characteristics are presented in Table 1 . The primary clinical outcomes related to depression, as well as anxiety and quality of life have been reported separately (see 11 ).

Psychological flexibility

AAQ-II scores decreased over time (i.e., increased psychological flexibility) (F (3,35)  = 8.74, p  < 0.001) and were significantly lower following psilocybin administration compared to post-placebo (see Fig.  2 and Table 2 ). The significant reduction in AAQ-II scores was maintained through week 16.

( B ) Significant increases in valued living at 2 weeks and 4 weeks post-psilocybin relative to baseline. Note. Statistical significance relative to baseline = * p  < .05, ** p  < .01, *** p  < .001. Statistical significance relative to previous time point =  ## p  < .01.

Values-congruent living

VLQ scores increased over time (i.e., improvement in values-congruent living) (F (3,36)  = 2.99, p  = 0.044) and were significantly increased 2 weeks following psilocybin administration compared to baseline but not compared to post-placebo (see Fig.  2 and Table 2 ). The increases in VLQ scores remained significant through week 16. Scores were not significantly improved following placebo.

Mindfulness

Time analyses were conducted for each of the 4 subscales of the KIMS (see Fig.  3 and Table 2 ). Significant increases (i.e., improvements) were observed on the Describe (F (3,36)  = 2.87, p  = 0.05) and Accept Without Judgment subscales (F (3,36)  = 3.38, p  = 0.029). Describe and Accept Without Judgment were significantly increased 2 weeks following psilocybin administration compared to baseline but not compared to post-placebo. The increased scores remained significant through week 16. Describe and Accept Without Judgment were not significantly improved following placebo. There were no significant changes in the Observe (F (3,36)  = 0.72, p  = 0.548) or Awareness (F (3,36)  = 2.02, p  = 0.129) scales.

Changes in mindfulness domains. ( A ) Significant increases in Acceptance Without Judgment at 2 weeks and 4 weeks post-psilocybin relative to baseline.

Relationship between changes in depression symptoms and changes in psychological flexibility and accept without judgment

Depression scores (QIDS-SR-16) decreased from 1 day before (mean = 16.79, SE = 0.95) to 2 weeks after (mean = 11.74, SE = 1.49) placebo (Δ mean = 5.05, p  = 0.005). There was not a significant correlation between change in depression scores and change in either (a) psychological inflexibility (Spearman's rho = 0.30, p  = 0.295) or (b) Accept Without Judgment (Spearman's rho = -0.42, p  = 0.140) during this time period.

Depression scores decreased from 2 weeks before (mean = 11.71, SE = 1.49) to 2 weeks after (mean = 6.27, SE = 1.38) psilocybin (Δ mean = 5.47 , p  = 0.016). Reductions in depression scores were significantly associated with (a) decreases in psychological inflexibility (Spearman's rho = 0.88, p  < 0.001) and (b) increases in Accept Without Judgment (Spearman's rho = -0.64, p  = 0.014) during this time period (Fig.  4 ).

Association between post-psilocybin changes in depression severity and psychological inflexibility/Accept Without Judgment. ( A ) Significant positive association between reductions in psychological inflexibility and depression severity. ( B ) Significant negative association between increases in Acceptance Without Judgment inflexibility and reductions in depression severity.

This placebo-controlled, within-subject, fixed-order trial among participants with long-standing and predominantly treatment-resistant major depression documented significant and durable improvements in measures of psychological flexibility, mindfulness, and valued living following administration of both placebo and a moderate dose of psilocybin in combination with ACT-based psychotherapy. Improvements in psychological flexibility were significantly greater 2 weeks after psilocybin compared to 2 weeks after placebo and were maintained for 3 months after the psilocybin dosing session. Moreover, following psilocybin administration, improvements in measures of psychological flexibility (AAQ-II) and experiential acceptance (KIMS, Accept Without Judgment scale) were significantly correlated with reductions in depression severity.

The significant improvements in psychological flexibility observed post-psilocybin are in line with the aim of the study design to integrate psilocybin dosing sessions within a psychotherapeutic platform that specifically targets psychological flexibility. These results are consistent with previous naturalistic research indicating that classic psychedelic use is associated with improvements in psychological flexibility 21 , 36 , 65 and are the first to extend this finding to psilocybin or a clinical trial specifically. Given the significant improvement in psychological flexibility post-psilocybin compared to post-placebo, as well as the finding that values-congruent living and mindfulness domains only significantly improved following psilocybin dosing, our data suggests that the psilocybin dosing session had a significant impact on these psychological domains. In other words, the results suggest that improvements in psychological flexibility are likely not attributable exclusively to the ACT-based psychotherapeutic platform or placebo effects. However, carryover effects from the placebo phase of the study are a potential contributing factor given the within subject study design.

Additionally, significant increases were found over time for values-congruent living and in two domains of mindfulness (Acceptance Without Judgment and Describe). While these increases only became significant following psilocybin dosing, they were not significantly greater post-psilocybin compared to post-placebo. These results may be attributable to several factors, including the ACT-based therapeutic intervention itself being the cause of improvements in these domains, minimal power to detect psilocybin specific effects, and issues with the fixed-order design of the study (e.g. carryover effects, gains occurring in the early phase of treatment 66 ). Of note, no significant overall time effect was observed for the mindfulness domains of Observe and Awareness. These findings are in line with previous research that has found significant improvement in experiential acceptance following psilocybin-assisted therapy 5 and mindful non-judgment following the administration of psilocybin but no significant changes in other facets of mindfulness following the administration of psilocybin 50 .

The significant associations between reductions in depression severity and increases in psychological flexibility and experiential acceptance support the notion that changes in psychological flexibility and related concepts of mindfulness and acceptance may be important psychological mechanisms of change in psilocybin-assisted therapy of depression, and perhaps, other disorders. These findings are especially notable given that the parent clinical trial did not find a significant correlation between the strength of mystical-type experience during psilocybin dosing and reductions in depression 11 . While it is possible that a small sample size and limited variability in MEQ scores during psilocybin dosing contributed to the latter finding, it is also possible that there may be more essential acute experiences (e.g., psychological insight, emotional breakthrough) and post-acute changes (e.g., increases in psychological flexibility and experiential acceptance) that predict psilocybin treatment outcomes. It is important to note that the correlation between reductions in depression severity and increases in psychological flexibility do not necessarily imply causation and it is possible that improvements in depression also lead to greater psychological flexibility. Nonetheless, these findings are consistent with past survey-based, observational, and clinical research linking post-psychedelic increases in psychological flexibility 21 , 36 , 37 , 38 , 65 and experiential acceptance 22 , 41 with improvements in depression severity and a range of mental health outcomes.

Limitations and future directions

An important limitation of this within-subject study is the inability to fully disambiguate the relative contribution of each therapeutic intervention (placebo dosing, psilocybin dosing, and ACT-based psychotherapy) to the results observed. Because of this, as well as the possibility of carryover effects from the placebo phase, the persisting psychological changes observed following psilocybin dosing cannot be definitively attributed specifically to psilocybin. Moreover, given that we did not compare ACT-based therapy to another therapeutic approach, it is unclear if similar results would have been observed if the therapists had used a non-ACT-based model (e.g. psychological support) to guide preparation and integration. Future studies may attempt to compare the relative efficacy of different therapeutic modalities or the amount of psychotherapeutic support provided.

Furthermore, findings from the present study cannot firmly establish a causal effect of psilocybin therapy on psychological flexibility (for further discussion, see 67 ). Additional research remains necessary to elucidate the potential mechanistic role of psychological flexibility within psilocybin therapy. For instance, intensive longitudinal designs (e.g., the use of ecological momentary assessment) may help to further elucidate the temporal relationship between changes in psychological flexibility and depressive symptoms. Similarly, dose–response studies with variable dosages of psilocybin and amounts of psychotherapy may also help to establish the gradient of the relationship between psychological flexibility and depressive symptoms within psilocybin therapy. Future research examining the effects of psilocybin-assisted therapy on psychological flexibility (and its subdomains) should also include alternative measures of psychological flexibility (e.g., the Multidimensional Psychological Flexibility Inventory 68 ), given significant concerns regarding the validity of the AAQ-II as a measure of psychological flexibility 69 , 70 , including its overlap with measures of distress and its single factor measurement of psychological flexibility.

Finally, findings from the present study should be interpreted in light of difficulties with blinding and the likely contribution of expectancy effects (for in depth discussion, see 11 , 71 ). This issue remains ubiquitous across psychedelic research 72 and is likely a problem more broadly within psychiatry (e.g., see 73 ).

In conclusion, this placebo-controlled, within-subject, fixed-order trial of psilocybin-assisted therapy for MDD demonstrated significant improvements in psychological flexibility, several facets of mindfulness (accept without judgment and describe, but not observe and awareness) and values-congruent living. Improvements in psychological flexibility (but not mindfulness or values-congruent living) were greater post-psilocybin compared to post-placebo. Additionally, improvements in psychological flexibility and experiential acceptance were strongly associated with reductions in depression severity. These findings support the theoretical premise of integrating psilocybin dosing sessions with psychotherapeutic platforms that target psychological flexibility and add to the emerging evidence that psychological flexibility may be an important putative mechanism of change in psilocybin-assisted therapy for MDD and potentially, other mental health conditions.

What the U.K.’s explosive Cass Review means for gender medicine in the U.S.

The report is a gauntlet thrown down to the biden administration and organizations supporting controversial treatments for children.

By Valerie Hudson

A 388-page bomb just dropped in the U.K., and reverberations will be felt around the world. The long-awaited final Cass Review — commissioned by the National Health Service on gender-related medical treatment — has just been published. Dr. Hilary Cass, the author of this independent review, is one of Britain’s preeminent pediatricians and formerly the president of the Royal College of Paediatrics and Child Health.

The Cass Review is painstaking in its detail and comprehensive in its scope. Its findings have already caused the U.K.’s Council for Psychotherapy to cease its advocacy for an uncritically affirming stance for those with gender dysphoria. In anticipation of the final report, last month the U.K. banned the NHS from providing puberty blockers, cross-sex hormones or surgery to minors. A law prohibiting private clinics from offering these practices is also in the works.

What does the Cass Review say?

Overall, it finds the evidence for the use of puberty blockers and cross-sex hormones as treatment for gender dysphoria to be quite weak.

With regard to puberty blockers, the review “found no evidence that puberty blockers improve body image or dysphoria, and very limited evidence for positive mental health outcomes, which without a control group could be due to placebo effect or concomitant psychological support.”

Additionally, the use of puberty blockers was not only associated with significant loss in bone density, but the review found evidence that “brain maturation may be temporarily or permanently disrupted by the use of puberty blockers, which could have a significant impact on the young person’s ability to make complex risk-laden decisions, as well as having possible longer-term neuropsychological consequences.”

The effects of puberty blockers may not, then, be reversible. In fact, the review notes, “given that the vast majority of young people started on puberty blockers proceed from puberty blockers to masculinising/ feminising hormones, there is no evidence that puberty blockers buy time to think, and some concern that they may change the trajectory of psychosexual and gender identity development.”

With regard to the use of cross-sex hormones, similar conclusions are reached: “There is a lack of high-quality research assessing the outcomes of hormone interventions in adolescents with gender dysphoria/incongruence, and few studies that undertake long-term follow up. No conclusions can be drawn about the effect on gender dysphoria, body satisfaction, psychosocial health, cognitive development, or fertility. Uncertainty remains about the outcomes for height/growth, cardiometabolic and bone health.”

Noting the lack of evidence as to benefits and harms, the author concludes that it is unethical to prescribe these medications to anyone under the age of 18, and possibly unethical to prescribe them to anyone younger than their mid-20s, when full executive reasoning has been achieved.

Proponents of gender-altering medical treatment have argued that treatment lowers the risk of suicide among gender dysphoric young people but Cass does not find this to be the case. The report says: “[I]t is well established that children and young people with gender dysphoria are at increased risk of suicide, but suicide risk appears to be comparable to other young people with a similar range of mental health and psychosocial challenges. Some clinicians feel under pressure to support a medical pathway based on widespread reporting that gender-affirming treatment reduces suicide risk. This conclusion was not supported by the systematic review. In summary, the evidence does not adequately support the claim that gender-affirming treatment reduces suicide risk.”

Given no real evidence of any improvement with use of puberty blockers and cross-sex hormones in gender dysphoric children, and given the clear gaps in the research literature, the review concludes that there can be no informed consent on the part of either parents or patients to this treatment. Without the possibility of informed consent, it is patently unethical for doctors to prescribe such treatments.

The Cass Review also weighs in on the issue of social transition, which has been a source of conflict between schools and parents in the U.K.

While U.K. schools are prepared to socially transition a child — and to do so without informing parents — the Cass Review asserts that social transition is consequential, especially for younger children. The review notes, “sex of rearing seems to have some influence on eventual gender outcome, and it is possible that social transition in childhood may change the trajectory of gender identity development for children with early gender incongruence. For this reason, a more cautious approach needs to be taken for children than for adolescents.” For this reason, the U.K. government has recently issued guidance to stop schools from socially transitioning children.

The concept of “conversion therapy” also needs to be rethought, according to the Cass Review. Given the significantly higher rate of mental health comorbidities of gender dysphoric children compared to controls, it is important that mental health professionals be allowed to investigate whether a child’s gender dysphoria may be relieved through psychological interventions. Proposed bans on “conversion therapy” might stifle such needed therapy.

Furthermore, the review insists that detransitioning support also be provided by the NHS since, according to Cass, the number of detransitioners appears to be increasing.

All in all, the Cass Review is an important achievement. It will be the foundation for an almost 180-degree turn in how the National Health Service treats gender dysphoric children. It is also a massive repudiation of the care guidelines put forward by WPATH, the World Professional Association of Transgender Healthcare. The guidelines have been unjustifiably influential given their “lack [of] developmental rigour,” as the review politely puts it.

But the report represents more, at least to Americans. It is a gauntlet thrown down to U.S. professional organizations, such as the American Medical Association, the American Academy of Pediatrics and the American Psychological Association, all of which have uncritically adopted the clearly unethical WPATH approach. It is also a gauntlet thrown down to the Biden administration, which has followed suit.

With the publication of the Cass Review, American institutions must rethink their approach to the treatment of gender dysphoric children. That approach is now clearly seen to be wrong, and can no longer be ethically justified.

I’m planning on mailing a copy of the review to the U.S. Department of Health and Human Services, care of Dr. Rachel Levine.

Real-World Data Analysis of Adverse Events Attributable to Large Joint Arthroplasty Implants

2023 FDA Science Forum

Background:

With various adverse events reportedly associated with metal implants, their clinical manifestations and biological underpinnings remain unclear. We employed a comprehensive analysis using real-world data (RWD) from electronic health records (EHR) to explore arthroplasty implant-related adverse outcomes with respect to device/patient characteristics.

This research aims to: 1) outline the scope, frequency, and underlying nature of clinically relevant adverse outcomes potentially attributable to arthroplasty implants; 2) explore pre-implantation risk factors and post-implantation complications likely associated with arthroplasty implant reactivity; and 3) develop device-oriented RWD analysis/visualization algorithms.

This research focused on large joint arthroplasty,utilized an EHR dataset of ~27,000 patients who had an arthroplasty encounter (2016 - 2019) that was collated by Loopback Analytics LLC for FDA. Cohorts with hip, knee, or shoulder arthroplasty were established using standardized ICD-10 codes. Comorbidity analysis with respect to the implantation time was performed in subjects with Revision and known arthroplasty-related Adverse Outcomes (AO+Rev) versus those without these outcomes (Control). Inter-cohort differences were assessed using chi-square test with odds ratios, relative risk ratios, and multivariate regression. Time-to-event analysis using Kaplan-Meier approach, log-rank test, and Cox proportional hazards regression were applied to evaluate the inter-cohort differences in pre-selected conditions representing potential implant-related immune/inflammatory responses. LASSO regression modelling was conducted as an unsupervised assessment of diagnoses that may predict AO+Rev. The co-occurrence and correlations between diagnoses pairs were assessed and visualized by network analysis; comorbidity score was introduced to quantify the correlations pertaining to diagnoses that may represent arthroplasty implant reactivity. Hierarchical clustering and correlation heatmaps were applied to visualize the intergroup differences in AO+Rev vs. Control comorbidity patterns and relationships between diagnoses of interest.

Compared to Controls, the AO+Rev cohort showed distinct likelihoods of different diagnoses that potentially represent arthroplasty-related underlying patient conditions (pre-implantation) or underrecognized complications (post-implantation), including some allergic and immune/inflammatory conditions. Different RWD analysis/visualization approaches with the respective results will be illustrated.

Conclusion:

The developed RWD algorithm can be applied for providing insights into the risk factors and complications pertaining to various arthroplasty implants, thereby optimizing leading to a more predictive evaluation of implant safety in the real-world setting.

A Simple Technique for Removing Microplastics from Drinking Water Revealed by Research

A s microplastic fragments increasingly infiltrate our systems, largely through consumption of contaminated food and drink, scientists are seeking effective solutions to combat this issue.

Researchers from China’s Guangzhou Medical University and Jinan University have discovered a straightforward method to extract these tiny plastic pieces from water.

The team experimented with both softened water and mineral-rich hard tap water , introducing nanoplastics and microplastics (NMPs) to the samples, following which they boiled and subsequently filtered the mixture to remove the remaining solids.

In some experiments, this boiling and filtering process successfully eliminated up to 90 percent of the NMPs, depending on the nature of the water being treated. This technique is especially convenient since it can be carried out using common kitchen equipment.

The research team states, “This uncomplicated boiling strategy can ‘decontaminate’ NMPs from household tap water, potentially reducing human consumption of NMPs from drinking water,” in their published work .

Hard water, well-known for its tendency to develop limescale, or calcium carbonate , upon heating, showed greater NMP removal. The kettle’s familiar white deposits capture the microplastics as the calcium carbonate separates from the water during boiling.

The method proved effective even with softened water, which contains less calcium carbonate—approximately one-quarter of the NMPs were caught in this case. Trapped within a calcium carbonate layer, these plastic particles were then filtered out using a simple tool, such as a thin stainless steel mesh typical for tea-straining, according to the researchers.

Previous research has detected traces of various plastics like polystyrene and polyethylene in drinking water, leading to routine ingestion. To test their solution further, the researchers introduced an excess of nanoplastics, which subsequently saw a reduced presence.

As stated by the researchers, “Drinking boiled water appears to be a feasible long-term solution for diminishing worldwide NMP exposure,” despite the fact that this practice is not common globally and is mostly traditional in a few regions. [source]

The study aims to encourage the habit of water boiling prior to consumption, especially with microplastic contamination on the rise globally.

While the exact health implications of microplastic ingestion remain to be fully understood, there is increasing concern regarding its contribution to disturbance of gut microbiota and antibiotic resistance in humans.

The authors of this study express a need for further exploration into the role of boiled water in preventing the introduction of synthetic materials into our systems and mitigating the alarming impacts of microplastics.

“Our outcomes affirm a highly practical approach to minimize human NMP exposure and contribute to the groundwork for conducting broader investigations involving a much larger sample collection,” the team shares .

The research was detailed in the journal Environmental Science & Technology Letters .

FAQ Section:

Q: What are microplastics?

A: Microplastics are small plastic fragments typically less than five millimeters in size, resulting from the breakdown of larger plastic debris or from manufactured products such as microbeads in personal care items.

Q: How do microplastics end up in drinking water?

A: Microplastics enter water systems through various sources, including industrial runoff, waste water discharge, and the breakdown of larger plastics in the environment. They have been found in both tap and bottled water.

Q: Is boiling water an effective way to remove microplastics?

A: Yes, according to the study by researchers from Guangzhou Medical University and Jinan University, boiling water and then filtering it can remove a significant portion of microplastics from drinking water.

Q: Are there health risks associated with consuming microplastics?

A: The health effects of consuming microplastics are not yet fully understood, but there is concern that they can lead to changes in the gut microbiome and increased antibiotic resistance.

Q: How can the average person remove microplastics from their drinking water at home?

A: Based on the study, individuals can boil their tap water and use a household filter, such as one made of stainless steel mesh typically used for straining tea, to remove any trapped microplastics.

Conclusion:

Microplastic contamination in drinking water is a growing concern with potential health implications. However, the study from Guangzhou Medical University and Jinan University offers a practical solution for individuals looking to reduce their exposure to microplastics. By boiling and filtering their water, people can take an active step toward limiting their intake of these synthetic particles. As research continues, there is a collective hope for broader acceptance of this water purification practice and a deeper understanding of the impacts of microplastics on human health.

Harvard and Caltech Will Require Test Scores for Admission

The universities are the latest highly selective schools to end their policies that made submitting SAT or ACT scores optional.

By Anemona Hartocollis and Stephanie Saul

Harvard will reinstate standardized testing as a requirement of admission, the university announced Thursday, becoming the latest in a series of highly competitive universities to reverse their test-optional policies.

Students applying to enter Harvard in fall 2025 and beyond will be required to submit SAT or ACT scores, though the university said a few other test scores will be accepted in “exceptional cases,” including Advanced Placement or International Baccalaureate tests. The university had previously said it was going to keep its test-optional policy through the entering class of fall 2026.

Within hours of Harvard’s announcement, Caltech, a science and engineering institute, also said it was reinstating its testing requirements for students applying for admission in fall 2025.

The schools had been among nearly 2,000 colleges across the country that dropped test score requirements over the last few years, a trend that escalated during the pandemic when it was harder for students to get to test sites.

Dropping test score requirements was widely viewed as a tool to help diversify admissions, by encouraging poor and underrepresented students who had potential but did not score well on the tests to apply. But supporters of the tests have said without scores, it became harder to identify promising students who outperformed in their environments.

In explaining its decision to accelerate the return to testing, Harvard cited a study by Opportunity Insights , which found that test scores were a better predictor of academic success in college than high school grades and that they can help admissions officers identify highly talented students from low income groups who might otherwise had gone unnoticed.

“Standardized tests are a means for all students, regardless of their background and life experience, to provide information that is predictive of success in college and beyond,” Hopi Hoekstra, dean of the faculty of arts and sciences, said in a statement announcing the move.

“In short, more information, especially such strongly predictive information, is valuable for identifying talent from across the socioeconomic range,” she added.

Caltech, in Pasadena, Calif., said that reinstating testing requirements reaffirmed the school’s “commitment as a community of scientists and engineers to using all relevant data in its decision-making processes.”

Harvard and Caltech join a growing number of schools, notable for their selectivity, that have since reversed their policies, including Brown, Yale, Dartmouth, M.I.T., Georgetown, Purdue and the University of Texas at Austin.

For Harvard, the move comes at a time of transition, and perhaps a return to more conservative policies.

Last June, the Supreme Court struck down race-conscious college admissions in cases involving Harvard and the University of North Carolina, raising fears that with the demise of affirmative action, those schools would become less diverse.

And in January, Harvard’s first Black president, Claudine Gay, resigned under pressure from critics who said she had not acted strongly enough to combat antisemitism on campus after the Oct. 7 attack by Hamas on Israel, and under mounting accusations of plagiarism in her academic work, which she stood by.

The provost, Alan Garber, was named interim president, while the dean of the law school, John Manning, became interim provost, the university’s second-highest administrative position. Mr. Manning is considered a strong potential candidate to replace Dr. Gay. His background stands out for his conservative associations, having clerked for the former Supreme Court justice Antonin Scalia.

In the current climate on campus, a return to test scores could be seen as a return to tradition. It also may address concerns of many parents that the college admissions process, especially in elite institutions, is inscrutable and disconnected from merit.

Applications to Harvard were down by 5 percent this year, while those at many of its peer universities went up, suggesting that the recent turmoil may have dented its reputation. But it still received a staggering number of undergraduate applications — 54,008 — and admitted only 3.6 percent. Requiring test scores could make sorting through applications more manageable.

Critics of standardized tests have long raised concerns that the tests helped fuel inequality because some wealthier students raised their scores through high-priced tutoring. But recent studies have found that test scores help predict college grades, chances of graduation and post-college success, and that test scores are more reliable than high school grades, partly because of grade inflation in recent years .

But Robert Schaeffer, director of public education at FairTest, an organization that opposes standardized testing, said Thursday that the Opportunity Insights analysis had been criticized by other researchers. “Those scholars say that when you eliminate the role of wealth, test scores are not better than high school G.P.A.,” he said, adding that it is not clear whether that pattern is true among the admissions pool at super selective colleges such as Harvard.

Mr. Schaeffer said that at least 1,850 universities remain test optional, including Michigan, Vanderbilt, Wisconsin and Syracuse, which have recently extended their policies. “The vast majority of colleges will not require test scores.” An exception, he said, could be the University of North Carolina system, which is considering a plan to require tests, but only for those students with a G.P.A. below 2.8.

Acknowledging the concerns of critics, Harvard said that it would reassess the new policy regularly. The school said that test scores would be considered along with other information about an applicant’s experience, skills, talents, contributions to communities and references. They will also be looked at in the context of how other students are doing at the same high school.

“Admissions officers understand that not all students attend well-resourced schools, and those who come from modest economic backgrounds or first-generation college families may have had fewer opportunities to prepare for standardized tests,” William R. Fitzsimmons, Harvard’s dean of admissions and financial aid, said in a statement.

Harvard said that in the interest of selecting a diverse student body, it has enhanced financial aid and stepped up recruitment of underserved students by joining a consortium of 30 public and private universities that recruits students from rural communities.

An earlier version of this article misstated Robert Schaeffer’s position. He is the director of public education at FairTest, not the director.
