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.

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.

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.

• 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.

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.

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 an excellent thesis conclusion [with examples]

Restate the thesis

Review or reiterate key points of your work, explain why your work is relevant, a take-away for the reader, more resources on writing thesis conclusions, frequently asked questions about writing an excellent thesis conclusion, related articles.

At this point in your writing, you have most likely finished your introduction and the body of your thesis, dissertation, or research paper . While this is a reason to celebrate, you should not underestimate the importance of your conclusion. The conclusion is the last thing that your reader will see, so it should be memorable.

A good conclusion will review the key points of the thesis and explain to the reader why the information is relevant, applicable, or related to the world as a whole. Make sure to dedicate enough of your writing time to the conclusion and do not put it off until the very last minute.

This article provides an effective technique for writing a conclusion adapted from Erika Eby’s The College Student's Guide to Writing a Good Research Paper: 101 Easy Tips & Tricks to Make Your Work Stand Out .

While the thesis introduction starts out with broad statements about the topic, and then narrows it down to the thesis statement , a thesis conclusion does the same in the opposite order.

• Restate the thesis.
• Review or reiterate key points of your work.
• Explain why your work is relevant.
• Include a core take-away message for the reader.

Tip: Don’t just copy and paste your thesis into your conclusion. Restate it in different words.

The best way to start a conclusion is simply by restating the thesis statement. That does not mean just copying and pasting it from the introduction, but putting it into different words.

You will need to change the structure and wording of it to avoid sounding repetitive. Also, be firm in your conclusion just as you were in the introduction. Try to avoid sounding apologetic by using phrases like "This paper has tried to show..."

The conclusion should address all the same parts as the thesis while making it clear that the reader has reached the end. You are telling the reader that your research is finished and what your findings are.

I have argued throughout this work that the point of critical mass for biopolitical immunity occurred during the Romantic period because of that era's unique combination of post-revolutionary politics and innovations in smallpox prevention. In particular, I demonstrated that the French Revolution and the discovery of vaccination in the 1790s triggered a reconsideration of the relationship between bodies and the state.

Tip: Try to reiterate points from your introduction in your thesis conclusion.

The next step is to review the main points of the thesis as a whole. Look back at the body of of your project and make a note of the key ideas. You can reword these ideas the same way you reworded your thesis statement and then incorporate that into the conclusion.

You can also repeat striking quotations or statistics, but do not use more than two. As the conclusion represents your own closing thoughts on the topic , it should mainly consist of your own words.

In addition, conclusions can contain recommendations to the reader or relevant questions that further the thesis. You should ask yourself:

• What you would ideally like to see your readers do in reaction to your paper?
• Do you want them to take a certain action or investigate further?
• Is there a bigger issue that your paper wants to draw attention to?

Also, try to reference your introduction in your conclusion. You have already taken a first step by restating your thesis. Now, check whether there are other key words, phrases or ideas that are mentioned in your introduction that fit into your conclusion. Connecting the introduction to the conclusion in this way will help readers feel satisfied.

I explored how Mary Wollstonecraft, in both her fiction and political writings, envisions an ideal medico-political state, and how other writers like William Wordsworth and Mary Shelley increasingly imagined the body politic literally, as an incorporated political collective made up of bodies whose immunity to political and medical ills was essential to a healthy state.

Tip: Make sure to explain why your thesis is relevant to your field of research.

Although you can encourage readers to question their opinions and reflect on your topic, do not leave loose ends. You should provide a sense of resolution and make sure your conclusion wraps up your argument. Make sure you explain why your thesis is relevant to your field of research and how your research intervenes within, or substantially revises, existing scholarly debates.

This project challenged conventional ideas about the relationship among Romanticism, medicine, and politics by reading the unfolding of Romantic literature and biopolitical immunity as mutual, co-productive processes. In doing so, this thesis revises the ways in which biopolitics has been theorized by insisting on the inherent connections between Romantic literature and the forms of biopower that characterize early modernity.

Tip: If you began your thesis with an anecdote or historical example, you may want to return to that in your conclusion.

End your conclusion with something memorable, such as:

• a call to action
• a recommendation
• a gesture towards future research
• a brief explanation of how the problem or idea you covered remains relevant

Ultimately, you want readers to feel more informed, or ready to act, as they read your conclusion.

Yet, the Romantic period is only the beginning of modern thought on immunity and biopolitics. Victorian writers, doctors, and politicians upheld the Romantic idea that a "healthy state" was a literal condition that could be achieved by combining politics and medicine, but augmented that idea through legislation and widespread public health measures. While many nineteenth-century efforts to improve citizens' health were successful, the fight against disease ultimately changed course in the twentieth century as global immunological threats such as SARS occupied public consciousness. Indeed, as subsequent public health events make apparent, biopolitical immunity persists as a viable concept for thinking about the relationship between medicine and politics in modernity.

The conclusion is the last thing that your reader will see, so it should be memorable. To write a great thesis conclusion you should:

The basic content of a conclusion is to review the main points from the paper. This part represents your own closing thoughts on the topic. It should mainly consist of the outcome of the research in your own words.

The length of the conclusion will depend on the length of the whole thesis. Usually, a conclusion should be around 5-7% of the overall word count.

End your conclusion with something memorable, such as a question, warning, or call to action. Depending on the topic, you can also end with a recommendation.

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):

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 based on your analysis, explain 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 highlighting their significance.

Importance of a Good Conclusion

A well-written conclusion provides 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 studies 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 your main argument(s) strengths and reiterates the most important evidence supporting those argument(s). Do this by clearly summarizing the context, background, and the necessity of examining the research problem 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., describe 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 analysis 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 topic, 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 paper addresses a critical, contemporary problem, warn readers of the possible consequences of not attending to the problem proactively based on the evidence presented in your study.
• 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 a source cited in 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 [topic studied within the field of study] to the specific [the research problem]. However, in the conclusion, your task is to move the discussion from specific [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 the structure of your paper as an hourglass--start with a broad introduction and review of the literature, move to the specific method of analysis and the 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 or surprising 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 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, but it often represents the key takeaway for your reader.

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 due to unforeseen factors or unanticipated variables. 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 concerning the validity and realiability of your research.

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 is why the conclusion rarely has citations to sources that haven't been referenced elsewhere in your paper. 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 have 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.

How to Write a Conclusion for a Research Paper

• Posted on May 12, 2023

The key to an impactful research paper is crafting an effective conclusion. The conclusion provides a final opportunity to make a lasting impression on the reader by providing a powerful summary of the main argument and key findings.

A well-written conclusion not only summarizes your research but also ties everything back to your thesis statement. Plus, it provides important takeaways for your reader, highlighting what they should remember from your research and how it contributes to the larger academic discourse.

Crafting an impactful conclusion can be tricky, especially in argumentative papers. However, with our expert tips and tricks, you can rest assured that your conclusion will effectively restate the main argument and thesis statement in a way that resonates with your audience and elevates your research to new heights.

Why is a Conclusion Necessary for a Research Paper? 

The conclusion of a research paper is essential in tying together the different parts of the paper and offering a final perspective on the topic. It reinforces the main idea or argument presented and summarizes the key points and findings of the research, highlighting its significance. 

Additionally, the conclusion creates a full circle of the research by connecting back to the thesis statement presented at the paper’s beginning. It provides an opportunity to showcase the writer’s critical thinking skills by demonstrating how the research supports the main argument.

The conclusion is essential for a research paper because it provides closure for the reader. It serves as a final destination that helps the reader understand how all the different pieces of information fit together to support the main argument presented. It also offers insights into how the research can inform future studies and contribute to the larger academic discourse.

It also ensures that the reader does not get lost in the vast amount of information presented in the paper by providing a concise and coherent summary of the entire research. Additionally, it helps the reader identify the paper’s main takeaway and understand how the research contributes to the larger body of knowledge in the field.

Leave a Lasting Impression

A well-crafted conclusion is an essential element of any research paper. Its purpose is to leave a lasting impression on the reader and tie together the different parts of the paper.

To achieve this goal, a conclusion should summarize the main points and highlight the key findings of the research. By doing so, the reader can easily understand the focus and significance of the study.

A strong conclusion should also discuss any important findings that can be applied in the real world. This practical perspective gives readers a better sense of the impact and relevance of the research.

Summarize Your Thoughts

The conclusion of a research paper should be concise and provide a summary of the writer’s thoughts and ideas about the research. 

It should go beyond simply restating the main points and findings and address the “so what” of the research by explaining how it contributes to the existing body of knowledge on the same topic. This way, the conclusion can give readers a better understanding of the research’s significance and relevance to the broader academic community.

Demonstrate How Important Your Idea Is

Moving beyond a superficial overview and delving into the research in-depth is crucial to create a compelling conclusion. This entails summarizing the key findings of the study, highlighting its main contributions to the field, and placing the results in a broader context. Additionally, it would help if you comprehensively analyzed your work and its implications, underscoring its value to the broader academic community. 

New Insights

The conclusion section of a research paper offers an opportunity for the writer to present new insights and approaches to addressing the research problem.

Whether the research outcome is positive or negative, the conclusion provides a platform to discuss practical implications beyond the scope of the research paper. This discussion can help readers understand the potential impact of the research on the broader field and its significance for future research endeavors.

How to Write a Killer Conclusion with Key Points

When writing a conclusion for a research paper, it is important to cover several key points to create a solid and effective conclusion.

Restate the Thesis

When crafting a conclusion, restating the thesis statement is an important step that reminds readers of the research paper’s central focus. However, it should not be a verbatim repetition of the introduction. 

By restating the thesis concisely and clearly, you can effectively tie together the main ideas discussed in the body of the paper and emphasize the significance of the research question. However, keep in mind that the restated thesis should capture the essence of the paper and leave the reader with a clear understanding of the main topic and its importance.

Summarize the Main Points

To write an impactful conclusion, summarizing the main points discussed in the body of the paper is essential. This final section provides the writer with a last opportunity to highlight the significance of their research findings. 

However, it is equally important to avoid reiterating information already discussed in the body of the paper. Instead, you should synthesize and summarize the most significant points to emphasize the key findings. By doing so, the conclusion can effectively tie together the research findings and provide a clear understanding of the importance of the research topic.

Discuss the Results or Findings

The next step is to discuss the results or findings of the research. The discussion of the results or findings should not simply be a repetition of the information presented in the body of the paper.

Instead, it should provide a more in-depth analysis of the significance of the findings. This can involve explaining why the findings are important, what they mean in the context of the research question, and how they contribute to the field or area of study. 

Additionally, it’s crucial to address any limitations or weaknesses of the study in this section. This can provide a more balanced and nuanced understanding of the research and its implications. By doing so, the reader will have a better understanding of the scope and context of the study, which can ultimately enhance the credibility and validity of the research.

Ruminate on Your Thoughts

The final step to crafting an effective conclusion is to ruminate on your thoughts. This provides an opportunity to reflect on the meaning of the research and leaves the reader with something to ponder. Remember, the concluding paragraph should not introduce new information but rather summarize and reflect on the critical points made in the paper.

Furthermore, the conclusion should be integrated into the paper rather than presented as a separate section. It should provide a concise overview of the main findings and suggest avenues for further research.

Different Types of Conclusions 

There are various types of conclusions that can be employed to conclude a research paper effectively, depending on the research questions and topic being investigated.

Summarizing

Summarizing conclusions are frequently used to wrap up a research paper effectively. They restate the thesis statement and provide a brief overview of the main findings and outcomes of the research. This type of conclusion serves as a reminder to the reader of the key points discussed throughout the paper and emphasizes the significance of the research topic.

To be effective, summarizing conclusions should be concise and to the point, avoiding any new information not previously discussed in the body of the paper. Moreover, they are particularly useful when there is a clear and direct answer to the research question. This allows you to summarize your findings succinctly and leave the reader with a clear understanding of the implications of the research.

Externalizing

On the opposite end of the spectrum are externalizing conclusions. Unlike summarizing conclusions, externalizing conclusions introduce new ideas that may not be directly related to the research findings. This type of conclusion can be beneficial because it broadens the scope of the research topic and can lead to new insights and directions for future research.

By presenting new ideas, externalizing conclusions can challenge conventional thinking in the field and open up new avenues for exploration. This approach is instrumental in fields where research is ongoing, and new ideas and approaches are constantly being developed.

Editorial conclusions are a type of conclusion that allows the writer to express their commentary on the research findings. They can be particularly effective in connecting the writer’s insights with the research conducted and can offer a unique perspective on the research topic. Adding a personal touch to the conclusion can help engage the reader and leave a lasting impression.

Remember that regardless of the type of conclusion you choose, it should always start with a clear and concise restatement of the thesis statement, followed by a summary of the main findings in the body paragraphs. The first sentence of the conclusion should be impactful and attention-grabbing to make a strong impression on the reader.

What to Avoid in Your Conclusion

When crafting your conclusion, it’s essential to keep in mind several key points to ensure that it is effective and well-received by your audience:

• Avoid introducing new ideas or topics that have not been covered in the body of your paper.
• Refrain from simply restating what has already been said in your paper without adding new insights or analysis.
• Do not apologize for any shortcomings or limitations of your research, as this can undermine the importance of your findings.
• Avoid using overly emotional or flowery language, as it can detract from the professionalism and objectivity of the research.
• Lastly, avoid any examples of plagiarism. Be sure to properly cite any sources you have used in your research and writing.

Example of a Bad Conclusion

• Recapitulation without Insight: In conclusion, this paper has discussed the importance of exercise for physical and mental health. We hope this paper has been helpful to you and encourages you to start exercising today.
• Introduction of New Ideas: In conclusion, we have discussed the benefits of exercise and how it can improve physical and mental health. Additionally, we have highlighted the benefits of a plant-based diet and the importance of getting enough sleep for overall well-being.
• Emotional Language: In conclusion, exercise is good for your body and mind, and you should definitely start working out today!

Example of a Good Conclusion

• Insights and Implications: In light of our investigation, it is evident that regular exercise is undeniably beneficial for both physical and mental well-being, especially if performed at an appropriate duration and frequency. These findings hold significant implications for public health policies and personal wellness decisions.
• Limitations and Future Directions: While our investigation has shed light on the benefits of exercise, our study is not without limitations. Future research can delve deeper into the long-term effects of exercise on mental health and explore the impact of exercise on specific populations, such as older adults or individuals with chronic health conditions.
• Call to Action: In conclusion, we urge individuals to prioritize exercise as a critical component of their daily routine. By making exercise a habit, we can reap the many benefits of a healthy and active lifestyle.

Final Thoughts 

When writing a research paper, the conclusion is one of the most crucial elements to leave a lasting impression on the reader. It should effectively summarize the research and provide valuable insights, leaving the reader with something to ponder.

To accomplish this, it is essential to include vital elements, such as restating the thesis , summarizing the main points, and discussing the findings. However, it is equally important to avoid common mistakes that can undermine the effectiveness of the conclusion, such as introducing new information or repeating the introduction. 

So to ensure that your research is of the highest quality, it’s crucial to use proper citations and conduct a thorough literature review. Additionally, it is crucial to proofread the work to eliminate any errors. 

Fortunately, there are many available resources to help you with both writing and plagiarism prevention.

How to Write a Thesis or Dissertation Conclusion

Published on September 6, 2022 by Tegan George and Shona McCombes. Revised on November 20, 2023.

The conclusion is the very last part of your thesis or dissertation . It should be concise and engaging, leaving your reader with a clear understanding of your main findings, as well as the answer to your research question .

In it, you should:

• Clearly state the answer to your main research question
• Summarize and reflect on your research process
• Make recommendations for future work on your thesis or dissertation topic
• Show what new knowledge you have contributed to your field
• Wrap up your thesis or dissertation

While your conclusion contains similar elements to your discussion section , they are not the same thing.

Your conclusion should be shorter and more general than your discussion. Instead of repeating literature from your literature review , discussing specific research results , or interpreting your data in detail, concentrate on making broad statements that sum up the most important insights of your research.

As a rule of thumb, your conclusion should not introduce new data, interpretations, or arguments.

Depending on whether you are writing a thesis or dissertation, your length will vary. Generally, a conclusion should make up around 5–7% of your overall word count.

An empirical scientific study will often have a short conclusion, concisely stating the main findings and recommendations for future research. A humanities dissertation topic or systematic review , on the other hand, might require more space to conclude its analysis, tying all the previous sections together in an overall argument.

Your conclusion should begin with the main question that your thesis or dissertation aimed to address. This is your final chance to show that you’ve done what you set out to do, so make sure to formulate a clear, concise answer.

• Don’t repeat a list of all the results that you already discussed
• Do synthesize them into a final takeaway that the reader will remember.

An empirical thesis or dissertation conclusion may begin like this:

A case study –based thesis or dissertation conclusion may begin like this:

In the second example, the research aim is not directly restated, but rather added implicitly to the statement. To avoid repeating yourself, it is helpful to reformulate your aims and questions into an overall statement of what you did and how you did it.

Your conclusion is an opportunity to remind your reader why you took the approach you did, what you expected to find, and how well the results matched your expectations.

To avoid repetition , consider writing more reflectively here, rather than just writing a summary of each preceding section. Consider mentioning the effectiveness of your methodology , or perhaps any new questions or unexpected insights that arose in the process.

You can also mention any limitations of your research, but only if you haven’t already included these in the discussion. Don’t dwell on them at length, though—focus on the positives of your work.

• While x limits the generalizability of the results, this approach provides new insight into y .
• This research clearly illustrates x , but it also raises the question of y .

Prevent plagiarism. Run a free check.

You may already have made a few recommendations for future research in your discussion section, but the conclusion is a good place to elaborate and look ahead, considering the implications of your findings in both theoretical and practical terms.

• Based on these conclusions, practitioners should consider …
• To better understand the implications of these results, future studies could address …
• Further research is needed to determine the causes of/effects of/relationship between …

When making recommendations for further research, be sure not to undermine your own work. Relatedly, while future studies might confirm, build on, or enrich your conclusions, they shouldn’t be required for your argument to feel complete. Your work should stand alone on its own merits.

Just as you should avoid too much self-criticism, you should also avoid exaggerating the applicability of your research. If you’re making recommendations for policy, business, or other practical implementations, it’s generally best to frame them as “shoulds” rather than “musts.” All in all, the purpose of academic research is to inform, explain, and explore—not to demand.

Make sure your reader is left with a strong impression of what your research has contributed to the state of your field.

Some strategies to achieve this include:

• Returning to your problem statement to explain how your research helps solve the problem
• Referring back to the literature review and showing how you have addressed a gap in knowledge
• Discussing how your findings confirm or challenge an existing theory or assumption

Again, avoid simply repeating what you’ve already covered in the discussion in your conclusion. Instead, pick out the most important points and sum them up succinctly, situating your project in a broader context.

The end is near! Once you’ve finished writing your conclusion, it’s time to wrap up your thesis or dissertation with a few final steps:

• It’s a good idea to write your abstract next, while the research is still fresh in your mind.
• Next, make sure your reference list is complete and correctly formatted. To speed up the process, you can use our free APA citation generator .
• Once you’ve added any appendices , you can create a table of contents and title page .
• Finally, read through the whole document again to make sure your thesis is clearly written and free from language errors. You can proofread it yourself , ask a friend, or consider Scribbr’s proofreading and editing service .

Here is an example of how you can write your conclusion section. Notice how it includes everything mentioned above:

V. Conclusion

The current research aimed to identify acoustic speech characteristics which mark the beginning of an exacerbation in COPD patients.

The central questions for this research were as follows: 1. Which acoustic measures extracted from read speech differ between COPD speakers in stable condition and healthy speakers? 2. In what ways does the speech of COPD patients during an exacerbation differ from speech of COPD patients during stable periods?

All recordings were aligned using a script. Subsequently, they were manually annotated to indicate respiratory actions such as inhaling and exhaling. The recordings of 9 stable COPD patients reading aloud were then compared with the recordings of 5 healthy control subjects reading aloud. The results showed a significant effect of condition on the number of in- and exhalations per syllable, the number of non-linguistic in- and exhalations per syllable, and the ratio of voiced and silence intervals. The number of in- and exhalations per syllable and the number of non-linguistic in- and exhalations per syllable were higher for COPD patients than for healthy controls, which confirmed both hypotheses.

However, the higher ratio of voiced and silence intervals for COPD patients compared to healthy controls was not in line with the hypotheses. This unpredicted result might have been caused by the different reading materials or recording procedures for both groups, or by a difference in reading skills. Moreover, there was a trend regarding the effect of condition on the number of syllables per breath group. The number of syllables per breath group was higher for healthy controls than for COPD patients, which was in line with the hypothesis. There was no effect of condition on pitch, intensity, center of gravity, pitch variability, speaking rate, or articulation rate.

This research has shown that the speech of COPD patients in exacerbation differs from the speech of COPD patients in stable condition. This might have potential for the detection of exacerbations. However, sustained vowels rarely occur in spontaneous speech. Therefore, the last two outcome measures might have greater potential for the detection of beginning exacerbations, but further research on the different outcome measures and their potential for the detection of exacerbations is needed due to the limitations of the current study.

In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.

The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

While it may be tempting to present new arguments or evidence in your thesis or disseration conclusion , especially if you have a particularly striking argument you’d like to finish your analysis with, you shouldn’t. Theses and dissertations follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the discussion section and results section .) The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

For a stronger dissertation conclusion , avoid including:

• Important evidence or analysis that wasn’t mentioned in the discussion section and results section
• 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 of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

The conclusion of your thesis or dissertation should include the following:

• A restatement of your research question
• A summary of your key arguments and/or results
• A short discussion of the implications of your research

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 Conclusion for a Research Paper: Effective Tips and Strategies in 2024

by Imed Bouchrika, Phd

Co-Founder and Chief Data Scientist

Writing a research paper is both deemed an essential and dreaded part of academics. The writing process can actually be a fruitful experience, although many students see it as a daunting task. A research paper has lots of pivotal facets, each calling for knowledge-gathering, understanding the subject, and effort to put the pieces together. However, in this article, we will only pay attention to the conclusion and how to construct one that leaves a lasting impact on the readers.

According to Faryadi (2012), writing a conclusion is as difficult as writing the introduction; meanwhile, Holewa states that writing the conclusion is the hardest part of the writing process. As the last part of a research paper format , the conclusion is the point where the writer has already exhausted his or her intellectual resources. Conclusion, however, is what readers often remember the most and, therefore, must also be the best part of your written research (Holewa, 2004).

Unlike what others may have come to believe, the conclusion is not a mere summarization of an article, an essay, or a research paper. Simply put, the conclusion goes beyond restating the introduction and body of your research. In this article, we walk you through the process of formulating an effective research paper conclusion by understanding its purpose, the strategies you can use, and what you should avoid doing when writing a conclusion in a research paper.

What Is a Research Paper Conclusion?

So, what is conclusion in research? The conclusion is the part of the research paper that brings everything together in a logical manner. As the last part of a research paper, a conclusion provides a clear interpretation of the results of your research in a way that stresses the significance of your study. A conclusion must be more extensive and encompassing compared to a particular finding and, in the same vein, various findings may be integrated into a single conclusion (Baron, 2008).

Unlike the introduction where you open a dialogue with your readers about the problem and/or present research questions , arguments, and what knowledge gaps you aim to bridge, the conclusion provides a clear and concise picture of how you are able to accomplish all of these. The conclusion is where you describe the consequences of your arguments by justifying to your readers why your arguments matter (Hamilton College, 2014).

Derntl (2014) also describes conclusion as the counterpart of the introduction. Using the Hourglass Model (Swales, 1993) as a visual reference, Derntl describes conclusion as the part of the research paper that leads the readers from narrow or specific results to broader and more general conclusion.

While it is deeply interlinked with how to make conclusion in research, conclusion writing is another craft on its own. Good conclusion writing oftentimes has a mix of logical presentation and a good deal of rhetoric. So, one of the best ways to actually become better at it is to emulate the way your favorite researchers write or how conclusions are presented in similar papers.

Why Is Conclusion Necessary in a Research Paper?

Just like the final chord in a song, a conclusion is necessary to make a research paper complete and well done (CRLS Research Guide, 2018). While your introduction sets the expectations and the body of your research paper presents your methodology and detailed analyses, the conclusion is where you demonstrate the significance of your findings, insights, and observations. The conclusion creates a bigger picture of your research work that helps your readers view the subject of your study as a whole and in a new light.

As the author of your research paper, the conclusion plays an important role in giving you the opportunity to have the final word, create a good impression, and end your paper on a positive note. In order to achieve this, your conclusion must possess the key characteristics of an effective concluding section. And when someone asks what are the characteristics of research , an effective concluding section is one of the most important characteristics of a good research work.

In terms of length, the conclusions of professional empirical research articles usually have five to six paragraphs, while student/novice papers typically have two- to three-paragraph conclusions (Powner, 2017).

Effective Strategies in Writing a Conclusion

Your research paper conclusion is the opposite of the introduction not just in placement but also in structure. The introduction generally follows the inverted triangle format with the general statement element on top, narrowing down to the main point of research. The conclusion, on the other hand, follows the inverted introduction structure by opening with the highlights of your research and ending with a general but relevant statement that encourages readers to think, as well as challenges them to take action based on the new pieces of knowledge they have gained from your research paper (Purdue Global Campus, n.d.).

Several studies that analyzed how conclusions are framed (see for instance Bunton, 2005 and Lewkowicz, 2012) found that most authors either restate and consolidate a research problem or synthesize the research work. When consolidating the problem, authors either present the solutions, products, or results of a research problem and/or assumptions (Soler-Monreal, C. 2019). Nonetheless, in general, here are general tips on how to write conclusion in research better:

Synthesizing instead of summarizing

As mentioned previously, the research conclusion is not a summary of your research paper. While a summary can be an element of this section, the conclusion goes beyond simply restating your ideas and analyses. Instead of repeating what you already said in the abstract, introduction, and body of your study, demonstrate to your reader how the essential elements in your research paper coherently fit together (The Writing Center UNC, n.d.).

Echoing the introduction

This approach to writing the conclusion brings your reader to a full circle by using or referring to the same elements you used in your introduction or by drawing parallels. An example of this would be retelling a scenario you described in your introduction, but this time while creating a new understanding of the subject based on the results of your study that further reinforces your arguments and/or hypotheses.

Redirecting the reader

Your conclusion plays the role of being your readers’ bridge back to the real world after welcoming them into your study through your introduction and immersing them in your methodologies, analyses, and results. Redirecting your readers is a way of challenging them to take the information they get from your research study and apply them in real life. This strategy can also be approached by proposing a course of action for further studies or solutions to an existing issue.

Challenging your own conclusion

Also called the “so what" game, this strategy requires challenging your own ideas by asking yourself “So what?" while you are in the process of developing your conclusion. Once you are done putting your conclusion to paper, go through it with someone who will challenge what you wrote (The Writing Center UNC, n.d.). You can ask a friend to read your conclusion with you and have them ask “So what?" after every statement. This strategy can help you find loopholes in your conclusion and refine it in the process.

Addressing limitations

This strategy implores you, the researcher, to identify the weak points in your research paper, which include the aspects where your argument is lacking, or if there are instances where your conclusion might be incorrect. This strategy is useful in writing a conclusion of research for scientific papers as well as experiments (Writing Tutorial Services, Indiana University, n.d.).

Demonstrating ideas to create a new picture or meaning

All relevant data must be interpreted in appropriate depth. Explain how the methodologies or mechanisms used as well as your observations that help arrive at your study’s results. There are times when your study may not yield the results you expected. In cases such as this, explain to your readers why this may have happened. If the results are in line with your expectations, proceed to describe your theory supported by your evidence (Caprette, 1995).

Posing questions

Research studies are motivated by questions. Posing research questions , either to your readers or in general, may help your readers gain a new perspective on the topic, which they may not have held before reading your conclusion. It may also bring your main points together to create or develop a new idea from your research study.

What to Avoid Including in Your Conclusion

Coming up with an effective conclusion includes avoiding approaches that can hinder you from developing a compelling concluding section of your research paper. Here are some of the strategies to avoid when you are writing your research paper conclusion:

Generic and obvious opening phrases

Do not start your conclusion with generic phrases, such as “In conclusion," “In summary," “In closing," etc. While this may be an effective transition during an oral presentation, it does not work the same way on actual paper where your readers can tell exactly which part of your paper they are reading.

Adding new information

The conclusion part of your research paper should have room for any information relevant to your study but is not referenced anywhere else in your research paper. All significant information should be in the body. Conclusion is not the appropriate section to introduce new information as it is where you are supposed to communicate with your readers the value of your research study.

Long and elaborate discussion

Your research paper’s conclusion must be concise and straightforward. Avoid dwelling on descriptions and interpretations that should have been in the body of your paper, including discussing methodologies and results of your studies in detail. While a brief summary of your study is included in your conclusion, the focus should be more about the insights, evaluations, implications, etc., drawn from your study (Sacred Heart University Library, n.d.).

Apologizing

As you reach the concluding part of your research paper, you may have doubts regarding your research paper. You may question yourself if you have done enough work and may feel compelled to apologize. Do not undermine your authority over your research by expressing doubts regarding your approach and apologizing for not being able to include other methodologies that you may deem to be better than yours. You are aware that you have immersed yourself in your research and have covered all the bases to produce a sound and well-backed research study.

Appealing to your readers’ emotions

Your conclusion, just like the rest of your research paper, is meant to be analytical, not emotional. Avoid making sentimental statements to appeal to your readers’ emotions as this has the tendency to fall out of character with what should be a logical and scientific research study (The Writing Center UNC, n.d.).

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.

Research Paper Conclusion Examples

When it comes to writing a conclusion for your research paper, examining examples can offer valuable insights. Let’s take a look at this comprehensive example given below:

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!

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 Conclusion for a Research Paper: Examples & Tips

You might be wondering about how to write a conclusion paragraph for a research paper. It may seem like your readers should understand your main arguments by the end, so there is no need for it. However, there are several aspects that prove the importance of a conclusion section in research.

Its first and primary function is, of course, a summary of all the main ideas and evidence in the paper. Sometimes research can be quite lengthy so putting all the thoughts you want to share in one place is very handy. Moreover, the conclusion shows how important your work is and suggests new ways of looking at the problem.

Our guide and research paper conclusion example are here to help you with your assignment!

• ❗ Importance of a Conclusion
• 👣 Writing Steps
• 📑 Conclusion Types & Examples
• ❌ Common Mistakes

🔗 References

❗ importance of a conclusion in a research paper.

A conclusion intends to remind the readers about the main arguments and findings of the whole paper. However, it also highlights the significance of the work. Both these functions help create a long-lasting, memorable impression from your research paper , so always include this part and try to think of the ways to make it even more effective.

Since having a strong concluding paragraph is so crucial for the overall success, you might want to check out a step-by-step guide on writing it. It can assure you don’t miss any vital moments. Moreover, you need to find out what conclusion type would be the best!

👣 How to Write a Conclusion for a Research Paper Step by Step

Below are only a few simple steps that can allow you to write the most persuasive research paper.

📑 Types & Examples of Research Paper Conclusions

You may be assigned to write a persuasive or argumentative paper. Or your professor might ask you to develop an analytical or comparative research paper.

Should you write their conclusions in the same way? The answer is “No”. When you write different types of assignments, you need different conclusions.

Argumentative Research Paper Conclusion

To write an excellent argumentative paper conclusion, you need to highlight the most persuasive and strong arguments you have — no need to add many details. In addition, don’t forget you should include the essential components of the conclusion, such as paraphrasing your thesis statement, which points out your opinion on the chosen topic. If you used a strong thesis statement generator , it won’t be hard to do.

Argumentative Research Paper Conclusion Example

Right now, Earth is facing the issue of the sixth extinction, which causes numerous species to fade every day. There are at least three ideas people might use to prevent their total extinction in the next fifty years. More ways of recycling, new approaches to plastic production, and conservation of species could be life-saving.

Analytical Research Paper Conclusion

First, you should restate your thesis statement and summarize the critical points of your arguments. The main difference between the analytical research paper conclusion and other types is that there should definitely be a highlight of a broader context. It means you can add some meaning to the findings.

Analytical Research Paper Conclusion Example

Elon Musk has made a revolution in the way we pay, drive, and even fly. His ideas come only from the desire to make things easier, but eventually, they change the world. Musk first thought about PayPal when he was a student, and now it’s one of the most popular online payment systems. The same with Tesla cars.

Comparative Research Paper Conclusion

An effective comparative paper conclusion requires some analytical skills. You need to be very careful in looking through facts to clearly formulate your findings. Moreover, the sources need to be trustworthy. And, as usual, you need to add a paraphrased thesis statement and a few words about the importance of your study research.

Comparative Research Paper Conclusion Example

Electric cars are proven to be more efficient and effective than gas cars. Not only do they produce fewer emissions, but the drivers reach their destination point faster. Moreover, gas cars are more expensive to maintain. It all derives from the specifics of the electric cars’ engines, which are much simpler.

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

Introduction

A well-crafted conclusion is essential to the success of any research paper. It not only ties together the entire paper but also reinforces the significance of the study, leaving a lasting impression on the reader. The Writing Planet, renowned for its custom research paper writing services , understands the pivotal role a conclusion plays. Whether you’re looking for a custom research paper for me or need assistance from a custom research paper service for me, The Writing Planet is here to help.

What is a Conclusion in a Research Paper?

Definition and purpose of a conclusion in a research paper.

A conclusion in a research paper serves as the final summary and synthesis of the key points discussed throughout the paper. It encapsulates the main findings, reflects on the implications of the research, and provides a final perspective on the topic. Unlike the introduction or the body, which detail the journey of the research, the conclusion emphasizes the destination.

How It Differs from Other Sections of the Paper

The conclusion differs from the introduction and the body in that it does not introduce new information or arguments. Instead, it summarizes what has already been presented, underscores the significance of the research, and sometimes suggests areas for future study. It is the last chance to reinforce the study’s impact and ensure the reader walks away with a clear understanding of its importance.

Types of Conclusions for Research Papers

Summarizing conclusion.

A summarizing conclusion is the most common type, where the writer restates the main points of the research paper. This type of conclusion succinctly encapsulates the key arguments, findings, and evidence, reminding the reader of the core content without introducing new information.

Editorial Conclusion

An editorial conclusion offers a personal perspective or opinion on the research topic. This type of conclusion can be particularly effective in argumentative or opinion-based research papers , where the writer reflects on the broader implications of their findings and shares their viewpoint.

Externalizing Conclusion

An externalizing conclusion connects the research to broader, real-world scenarios. It discusses the implications of the research in practical terms, suggesting how the findings could be applied or what changes they could inspire in the field or society at large.

Importance of a Good Research Paper Conclusion

Why a strong conclusion is crucial for a research paper.

A strong conclusion is crucial because it encapsulates the essence of the research and reinforces its importance. It helps readers understand the significance of the study, ensuring that the main points are clear and memorable. A well-crafted conclusion also provides closure, leaving the reader with a sense of completion and satisfaction.

How It Leaves a Lasting Impression on the Reader

The conclusion is the last part of the paper that the reader encounters, making it a key component in leaving a lasting impression. A powerful conclusion can resonate with the reader, encouraging them to reflect on the research and its implications. It can also inspire further inquiry or action, underscoring the paper’s relevance and impact.

How to Write a Conclusion for Your Research Paper

Step-by-step guide to writing an effective conclusion.

Restate the Thesis: Begin by restating your thesis statement in a new way to reinforce the main point of your paper. Summarize Main Points: Briefly summarize the key arguments or findings discussed in the body of the paper. Discuss the Significance: Explain the importance of the findings and their implications for the field of study. Suggest Future Research: Highlight any gaps in the research and suggest areas for future study. End with a Strong Closing Statement: Conclude with a compelling final thought or call to action that leaves a lasting impact on the reader.

Tips and Best Practices for Making a Conclusion That Counts

Be Concise: Avoid unnecessary repetition and keep your conclusion brief and to the point. Stay Focused: Stick to the main points and resist the urge to introduce new information. Use Clear Language: Write clearly and concisely, ensuring your conclusion is easy to understand. Emphasize Impact: Highlight the significance of your research and its potential impact on the field or society. Reflect Your Voice: Maintain your unique voice and perspective, making your conclusion personal and engaging.

Research Paper Conclusion Examples

Example 2: Editorial Conclusion

“In reflecting on the findings, it is evident that renewable energy holds the key to a sustainable future. While challenges remain, such as cost and infrastructure, the benefits far outweigh the drawbacks. It is imperative that policymakers and stakeholders prioritize investments in renewable energy to safeguard our planet for future generations.”

Example 3: Externalizing Conclusion

“The implications of this research extend beyond the academic realm, suggesting practical applications in policy-making and industry. By adopting renewable energy solutions, governments and businesses can significantly reduce their carbon footprint and contribute to global sustainability efforts.

What is an Essay Conclusion?

An essay conclusion serves as the final segment of your written composition. It brings together all the ideas, arguments, and evidence presented throughout the essay and synthesizes them into a concise and coherent final statement. Think of it as the grand finale that encapsulates your main points and leaves a lasting impression on your readers.

How to Write an Essay Conclusion

To create a compelling essay conclusion, follow these step-by-step guidelines

Step 1: Restate your thesis:

Begin by restating your thesis statement, reminding readers of the central argument you have been supporting throughout your essay. However, avoid repeating it verbatim. Instead, rephrase it to maintain reader engagement.

Step 2: Summarize your main points:

Provide a succinct summary of the key points and arguments discussed in the body paragraphs. Focus on the most significant aspects while maintaining a logical flow. Avoid introducing new information or ideas at this stage.

Step 3: Emphasize the significance:

Highlight the broader implications of your essay’s topic and the relevance of your arguments in a wider context. Convey the importance of your findings and their potential impact on the subject matter or the reader’s perspective.

Step 4: Evoke emotions:

Create an emotional connection with your readers by emphasizing the significance of your topic or appealing to their values and beliefs. Stirring emotions can leave a lasting impact and make your conclusion more memorable.

Step 5: Offer a call to action or recommendation:

Depending on the nature of your essay, conclude with a call to action or a thoughtful recommendation that encourages readers to consider further action or reflection on the topic. This can inspire them to continue exploring or take specific steps related to the subject matter.

What is the ideal length for an essay conclusion?

The length of an essay conclusion varies depending on the overall length of your essay. As a general guideline, aim for a conclusion that is concise yet comprehensive, spanning approximately 10-15% of your total essay length.

Can I introduce new information in my essay conclusion?

Avoid introducing new information or arguments in your conclusion. Instead, focus on summarizing and reinforcing the ideas already presented, providing a sense of closure to your essay.

How can I make my essay conclusion more impactful?

To make your essay conclusion more impactful, strive for clarity, emotional resonance, and a sense of closure. Utilize strong language, vivid imagery, and rhetorical devices to leave a lasting impression on your readers.

Background: Growing evidence indicates a significant correlation between the gut microbiota, immune system, and psychiatric disorders. Nevertheless, the impacts and interactions of the gut microbiota and immunophenotypes on psychiatric disorders remain unclear. Methods: We utilized a bidirectional Mendelian randomization (MR) study to evaluate the causal associations among the gut microbiota, immunophenotypes, and psychiatric disorders, including attention-deficit/hyperactivity disorder (ADHD), major depressive disorder (MDD), posttraumatic stress disorder (PTSD), schizophrenia (SCZ), and Tourette's syndrome (TS). The primary analysis was conducted using the inverse variance weighted (IVW) method, with several complementary sensitivity analyses being performed to ensure the reliability of the results. Results: Our study reveals significant causal relationships between 22 immunophenotypes, 15 types of gut microbiota, and various psychiatric disorders. We further sought to ascertain whether immunophenotypes act as intermediaries in the pathway from gut microbiota to psychiatric disorders. In particular, three immunophenotypes were identified that mediate the causal effects of different gut microbiota on ADHD. Additionally, one immunophenotype was detected to mediate the causal effects of gut microbiota on PTSD. Conclusions: Our study indicates that immunophenotypes partially mediate the pathway from the gut microbiota to psychiatric disorders.

Background: Cerebral microbleeds (CMB) increase the risk for Alzheimer disease. Current neuroimaging methods that are used to detect CMB are costly and not always accessible.

Objective: This study aimed to explore whether the digital clock-drawing test (DCT) may provide a behavioral indicator of CMB.

Methods: In this study, we analyzed data from participants in the Framingham Heart Study offspring cohort who underwent both brain magnetic resonance imaging scans (Siemens 1.5T, Siemens Healthcare Private Limited; T2*-GRE weighted sequences) for CMB diagnosis and the DCT as a predictor. Additionally, paper-based clock-drawing tests were also collected during the DCT. Individuals with a history of dementia or stroke were excluded. Robust multivariable linear regression models were used to examine the association between DCT facet scores with CMB prevalence, adjusting for relevant covariates. Receiver operating characteristic (ROC) curve analyses were used to evaluate DCT facet scores as predictors of CMB prevalence. Sensitivity analyses were conducted by further including participants with stroke and dementia.

Results: The study sample consisted of 1020 (n=585, 57.35% female) individuals aged 45 years and older (mean 72, SD 7.9 years). Among them, 64 (6.27%) participants exhibited CMB, comprising 46 with lobar-only, 11 with deep-only, and 7 with mixed (lobar+deep) CMB. Individuals with CMB tended to be older and had a higher prevalence of mild cognitive impairment and higher white matter hyperintensities compared to those without CMB ( P <.05). While CMB were not associated with the paper-based clock-drawing test, participants with CMB had a lower overall DCT score (CMB: mean 68, SD 23 vs non-CMB: mean 76, SD 20; P =.009) in the univariate comparison. In the robust multiple regression model adjusted for covariates, deep CMB were significantly associated with lower scores on the drawing efficiency (β=–0.65, 95% CI –1.15 to –0.15; P =.01) and simple motor (β=–0.86, 95% CI –1.43 to –0.30; P =.003) domains of the command DCT. In the ROC curve analysis, DCT facets discriminated between no CMB and the CMB subtypes. The area under the ROC curve was 0.76 (95% CI 0.69-0.83) for lobar CMB, 0.88 (95% CI 0.78-0.98) for deep CMB, and 0.98 (95% CI 0.96-1.00) for mixed CMB, where the area under the ROC curve value nearing 1 indicated an accurate model.

Conclusions: The study indicates a significant association between CMB, especially deep and mixed types, and reduced performance in drawing efficiency and motor skills as assessed by the DCT. This highlights the potential of the DCT for early detection of CMB and their subtypes, providing a reliable alternative for cognitive assessment and making it a valuable tool for primary care screening before neuroimaging referral.

Introduction

It is widely shown that cerebrovascular diseases increase the risk of Alzheimer disease (AD) and other dementia [ 1 , 2 ]. Cerebral microbleeds (CMB) are one of such cerebrovascular abnormalities, defined as small chronic brain hemorrhages, likely caused by structural abnormalities of the small vessels of the brain [ 3 ]. The prevalence of CMB is estimated to be as high as 34% in people with ischemic stroke and 60% in people with nontraumatic intracerebral hemorrhage [ 4 ]. CMB have also been associated with cognitive impairment and increased risk for AD development across multiple studies [ 5 , 6 ]. CMB can be divided into 2 subclasses based on their location in the brain, that is, lobar and deep CMB. A recent meta-analysis reported a 75% increased risk of dementia with deep or mixed CMB [ 7 ].

In light of population aging demographics, these figures are concerning, and solutions for early detection of emergent disease and AD risk factors at a preclinical stage to prevent the disease’s development are urgently needed [ 8 ]. Neuroimaging methods, such as brain magnetic resonance imaging (MRI) and computerized axial tomography scans, are valuable tools to detect cerebrovascular pathology. Currently, lobar and deep CMB can only be identified by brain MRI. However, these imaging tools are costly and, in most cases, not accessible in rural areas and low-income contexts. There are over 50 million people estimated to live with dementia and AD worldwide, with the highest increases in lower- and middle-income countries [ 9 ]. The worldwide costs of dementia are estimated to amount to over US $1 trillion [ 10 ]. To drive down the costs and promote early detection of early brain pathology for AD risk, including CMB, which have subtle clinical symptoms, one promising approach is to explore new, inexpensive technologies such as digital neuropsychological assessments coupled with machine learning analytics to detect and screen for cerebrovascular diseases in clinic before applying neuroimaging tools and neuropsychological assessments [ 11 ].

The clock-drawing test (CDT; traditional, paper based) is an easily applicable cognitive test, and prior research has documented that patients with dementia with MRI evidence of vascular disease make more clock-drawing errors than other groups [ 12 - 14 ]. However, the traditional analog, manually scored CDT is limited by its low sensitivity and specificity for different brain diseases, especially at an early stage or where there is subtle brain pathology. Moreover, analog scoring systems are only able to generate a limited number of clock-drawing metrics [ 15 ]. Developing efficient tools to measure cognitive change and brain health, especially in the preclinical stage of AD, is necessary. Recently, the CDT has been transformed through the use of a digital ballpoint pen, replacing a conventional ink pen, and coupled with a dot pattern that provides raw, time-stamped data that capture the full performance sequence (digital clock-drawing test; DCT), thus, generating large, detailed data on cognition that cannot be derived using the traditional CDT [ 11 ]. Recently, the Framingham Heart Study (FHS) analyzed DCTs from 1833 participants using machine learning to detect cognitive nuances. The DCT showed superiority over existing methods such as the Mini Mental Status Examination in detecting early cognitive impairment and characterizing individuals along the AD trajectory [ 16 ]. In addition, the DCT has evidenced its diagnostic value for early screening for mild cognitive impairment (MCI) and AD [ 17 - 19 ]. Further, the DCT was also associated with biomarkers relevant to cognitive impairment and AD, collected by positron emission tomography imaging, for example, amyloid and τ pathology [ 20 ].

Given the important role of CMB in the development of AD, the value of operationalizing putative negative effects on behavior caused by CMB using less costly and more accessible diagnostic tools is evident. Using data from the FHS, we predicted that the DCT would be useful in detecting CMB in older adults without dementia. We also examined whether the DCT could detect CMB in different brain regions, for example, lobar and deep CMB.

Study Sample

FHS is a multigeneration, community-based, prospective cohort study in Framingham, Massachusetts. The FHS offspring cohort (Generation 2) has been longitudinally examined in 9 core examinations, with examinations occurring on average every 4 years between 1971 and 2014. Details about this cohort have been previously described elsewhere [ 21 ]. These participants also had serial neuropsychological and MRI scans on average every 5 years between 1999 and 2019 [ 22 ]. For this study, FHS Generation 2 participants who were over 45 years old and had brain MRI CMB data (2000-2009) and DCT assessments (2011-2018; n=1072) were included. For primary analyses, participants were excluded if they had dementia (n=23) or had a history of stroke (n=29).

Clock-Drawing Measures: the CDT Versus DCT

The manual for administering and scoring the CDT has been previously described [ 23 ]. The CDT score using this analog (hand-scored) method ranged from 0 (no abnormality) to 3 (severe impairment). The DCT was obtained using the digital pen technology from Anoto, and the time-stamped features were processed by Linus Health Inc. Similar to the original paper-pencil CDT, the DCT contains a command and a copy condition [ 20 ]. In brief, the DCT contains multiple objective measurements that were derived from approximately 5000 digital clock drawings using machine learning algorithms to precisely evaluate nuances in performance beyond successful task completion [ 24 ]. Variables from the command and copy versions were combined from the machine learning calculations into an overall command or copy score ranging from 0 to 100. A similar technique was used for the domain-specific subscores measuring drawing efficiency, information processing, simple motor, and spatial reasoning (see previous publications [ 20 , 25 ] and Table S1 in Multimedia Appendix 1 for details).

The FHS MRI protocol and CMB diagnosis criteria have been previously described [ 26 ]. Briefly, participants were imaged by a Siemens 1.5T MRI, using a 3D T1-weighted coronal spoiled gradient-recalled echo sequence. All images were transferred to and processed by the University of California Davis Medical Center without knowledge of clinical information. The MRI scans were conducted between 2000 and 2009 with gradient recalled echo T2-weighted sequences, allowing for the detection of CMB. Using recently published guidelines [ 27 ], CMB were defined as rounded or ovoid hypointense lesions on a T2*-GRE weighted sequence, measuring <10 mm in diameter and surrounded by brain parenchyma over at least half the circumference of the lesion. The presence, number, and location of CMB were determined. Reliability measures for CMB readings have previously been described [ 28 , 29 ]. In line with previous studies [ 29 ], CMB location in the brain was classified into subgroups based on assumed pathophysiology (cerebral amyloid angiopathy and hypertensive vasculopathy), and it was classified into 2 locations: deep and lobar, with each participant potentially having 1 or more CMB. All participants were grouped into 4 subgroups based on assumed pathophysiology (cerebral amyloid angiopathy and hypertensive vasculopathy), which included the no CMB (control) group and groups with lobar-only, deep-only, and mixed (deep+lobar) CMB. White matter hyperintensities (WMHs) were segmented with fluid-attenuated inversion recovery and gray matter with T1-weighted images by semiautomated procedures, as previously described [ 30 ]. WMHs were adjusted for head size (by dividing WMHs by the total cerebral volume).

Statistical Analysis

Baseline characteristics of study participants were evaluated for the total sample and for CMB status. To compare the CMB status groups, 2-tailed t tests were applied for continuous variables, and χ 2 tests or Fisher exact tests were applied for categorical variables. To facilitate standardized comparisons between different scales in the models adjusted for covariates, the digital clock variables were transformed to z scores (mean 0, SD 1), for example, the overall DCT score (percentage range 0%-100%) was rescaled to a z score after logit transformation; all other DCT scores were also rescaled to z scores to standardize the variables that have different value ranges. Robust multivariable linear regression models were applied to assess whether the DCT scores (outcomes variables) were significantly different between different CMB subgroups and no CMB (control) group. All models were adjusted for age, sex, education, WMHs, and the time difference between brain MRI and DCT. A sensitivity analysis was conducted by including subjects with dementia (n=23), or a history of stroke (n=29) that were excluded from the main models. To test whether the DCT facet scores could distinguish different CMB subgroups from no CMB (control group), we also calculated the area under the curve (AUC) of a receiver operating characteristic (ROC) curve analysis based on multinomial classification models that were adjusted for main confounding factors such as age, sex, time between examinations, and MCI. The AUC, ranging from 0.5 to 1, is a key metric for evaluating a classifier’s ability to distinguish between positive and negative outcomes. A value nearing 1 indicates a highly accurate model, while an AUC of 0.5 suggests performance equivalent to random chance, indicating no predictive power. The results were shown as beta estimates (β) with 95% CIs. Statistical significance was indicated by a P value <.05 (2-tailed tests). All statistical analyses were performed using R (version 4.2.1; R Foundation for Statistical Computing).

In our data analysis, we used several R packages and functions. Specifically, we used the rlm function from the MASS library for robust linear model fitting [ 31 ], the lmrob function from the robustbase library for MM-type estimator calculation in linear regression [ 32 ], and the sandwich library for robust SE estimation in nonlinear models [ 33 ]. Additionally, the pROC library facilitated ROC curve analysis and AUC value calculation [ 34 ].

Ethical Considerations

The study was conducted per the Declaration of Helsinki, and ethical approval was provided by Boston University’s Institutional Review Board (H-40620). All participants provided informed consent, and data was de-identified.

The 1020 participants from the FHS Generation 2 sample were on average aged 72 (SD 7.9) years, and 57.35% (n=585) of them were female ( Table 1 ). Among them, 64 (6.27%) participants had at least 1 CMB. Participants with CMB were more likely to be older ( P <.001), have MCI ( P =.02), and have greater WMHs ( P <.001). There were no differences between the participants with and without CMB for the traditional, analog-scored CDT, in either the command or copy condition. By contrast, participants with CMB showed a significantly lower overall combined command or copy DCT score ( P =.01) than those without CMB ( Table 1 ).

Table 1 shows that participants with CMB showed worse performance on several command and copy DCT domains. Specifically, participants with CMB scored lower on the command spatial reasoning ( P =.03), copy drawing efficiency ( P =.03), and information processing ( P =.01) subscales. We further divided participants with CMB into those who had CMB exclusively in lobar regions (46/64, 72%), those who had CMB only in deep regions (11/64, 17%), and those who had mixed lobar+deep CMB (7/64, 11%) and used the DCT domain score to examine CMB ( Table 2 ). After adjusting for covariates, there were no statistically significant differences in the overall DCT or domain scores between participants with any CMB ( P >.05), compared to those without CMB. However, when analyzing the subscales, participants with deep-only CMB had lower scores on the command simple motor subscale than the reference group (β=–0.86, 95% CI –1.43 to –0.30; P =.003). Additionally, participants with mixed (lobar+deep) CMB had lower scores on the command spatial reasoning subscale than the reference group (β=–1.70, 95% CI –2.29 to –1.11; P <.001). In contrast, participants with lobar CMB did not show associations with any domain score under both command and copy conditions of the DCT. The results were similar when including participants with dementia or stroke in the analysis (Table S2 in Multimedia Appendix 1 ).

Robust multivariate linear regression models were applied with DCT scores (overall score and domains) and CMB subtypes (lobar-only, deep-only, and any deep). The reference group were participants without CMB (n=956). The overall DCT score (percentage) was rescaled to a z score (mean 0, SD 1) after logit transformation and other DCT scores were rescaled to z scores (mean 0, SD 1) after logit transformation. Participants with dementia or stroke were excluded from the analysis (see sensitivity analysis with inclusion in Table S2 in Multimedia Appendix 1 ). All models were adjusted for age, sex, education, MCI, WMHs, and the time difference between brain MRI and the DCT. The results are shown as standardized β coefficients (β) with 95% CI. P values for statistical significance are indicated.

Next, we used all facets to explore the diagnostic potential of the DCT for CMB, with the subtypes of CMB as the predicted outcomes (lobar, deep, or mixed). In addition to including all facets in the analysis, we investigated which specific facet score had a relationship with the 3 CMB subtypes (ie, lobar-only, deep-only, and mixed; Tables S2 and S3 in Multimedia Appendix 1 ). Some features from the command condition were mainly associated with deep CMB, whereas the features from the copy condition were more likely to be associated with lobar CMB ( Figure 1 ). For example, in the command condition, the features including vertical spatial placement, horizontal spatial placement, clock face circularity, component placement, max speed, initiation speed, average speed, ink length, and drawing size were associated with deep CMB but not with lobar CMB. Whereas oscillatory motion was lower among participants with lobar CMB, this feature was higher among participants with deep CMB in the command condition. In the copy condition, the features long latency count, stroke count conformity, and noise were positively associated with lobar-only CMB, but not with deep-only CMB. The mixed (lobar+deep) CMB was significantly associated with lower oscillatory motion, lower horizontal spatial placement, higher clock face circularity, and higher component placement scores in the command condition and higher noise score in the copy condition ( Figure 1 and Tables S3 and S4 in Multimedia Appendix 1 ).

In the ROC curve analysis, the results indicated that DCT facet scores alone demonstrated discrimination, as evidenced by the AUCs between individuals without CMB and those with lobar CMB (AUC 0.74, 95% CI 0.66-0.82), deep CMB (AUC 0.80, 95% CI 0.63-0.98), and mixed CMB (AUC 0.89, 95% CI 0.68-1.00; Figure 2 A). After adjusting for sex and age, the AUC values were further improved. The AUC (95% CI) values for individuals without CMB and those with lobar CMB, deep CMB, or mixed CMB were 0.77 (0.71-0.84), 0.85 (0.73-0.98), and 0.97 (0.95-0.99), respectively ( Figure 2 B). Further adjustment for the time difference between brain MRI and DCT measurement and the prevalence of MCI at the brain MRI scan yielded similar AUC values for individuals without CMB and those with lobar CMB (0.76, 95% CI 0.69-0.83), deep CMB (0.88, 95% CI 0.78-0.98), or mixed CMB (0.98, 95% CI 0.96-1.00; Figure 2 C). Notably, the highest AUC was observed for the mixed CMB group, followed by a modest increase for the deep CMB group, and the lobar CMB group when compared to the no CMB group, highlighting the enhanced discriminatory ability of DCT facets in identifying different CMB subtypes after adjusting for relevant covariates.

This cross-sectional study in the FHS reveals the potential of the DCT as a cost-effective and objective screening tool for detecting CMB in different brain regions. Unlike the traditional CDT, the DCT offers detailed insights into cognitive function and demonstrates significant associations with CMB, particularly deep and mixed subtypes. The study highlights the limitations of traditional cognitive tests in detecting subtle brain abnormalities such as CMB and underscores the DCT’s value in early prediction of dementia risk.

Principal Findings

To our knowledge, our study is the first to evidence that the DCT reveals detailed, nuanced, and hidden information and can serve as a potentially useful screening tool to detect the presence of CMB in different brain regions. As CMB is a risk factor for AD [ 28 ] but is accompanied by no or very subtle clinical symptoms, it is costly for clinicians to use neuroimaging to detect CMB. In comparison, the DCT is more cost-effective and can be completed by patients within a couple of minutes with minimal assistance. Another advantage of the DCT is that it objectively captures detailed brain functions through automated digital collection and analysis, while the manual traditional counterpart depends on the subjective assessment by trained testers. Using the DCT may be useful for in future clinical practice for early screening and detection of CMB, triggering interventions that can delay the progress of the disease or prevent AD onset [ 35 ].

Comparison to Prior Work

Whereas the traditional CDT has low sensitivity and specificity to screen or diagnose participants with CMB, the DCT scores were significantly associated with CMB in our study, especially deep and mixed CMB, including across 3 different measurement levels (ie, overall score, domains, and facets of the DCT). Previous studies have reported inconsistent associations between CMB and the traditional CDT. For example, whereas 1 study found that CMB were a risk factor for low performance on the CDT [ 36 ], 2 others did not find a relationship [ 37 , 38 ]. Another study that did not exclude participants with dementia illustrated that lobar, but not deep, CMB were associated with CDT [ 39 ]. It is possible that CDT’s crude measurements contain mixtures of different cognitive functions that cannot be broken down into more detailed measurements such as facet scores of DCT and thus may not be able to clearly detect fine brain abnormalities like CMB.

Strengths and Limitations

There were several strengths in our study. First, in our study, the diagnostic discriminability using the DCT facet scores was able to differentiate those with and without CMB, especially the mixed subtype, independent from MCI. Second, the DCT is simple, can be self-administered, and could serve as a screening test before administering costly neuroimaging tests. Third, our study found that participants with lobar CMB and deep CMB had different DCT performance patterns. Whereas the command condition was more strongly associated with deep or mixed CMB, the copy condition may be more associated with lobar CMB. Since deep but not lobar CMB have been identified as risk factors for dementia development in previous studies [ 28 ], the DCT may be a valuable tool for the early prediction of dementia risk. By capturing multiple facets of cognitive function as well as their fine-grained interrelations, the DCT affords substantially more sensitive analyses compared to typical measures of domain-specific cognitive functions that are observed in isolation (or aggregated in sum scores that overlook fine-grained interrelations).

This study had several limitations. First, the sample size of deep and mixed CMB cases is relatively small, potentially limiting the generalizability of findings and statistical power to detect associations. Future studies should aim for larger and more diverse cohorts. Second, the associative study design restricts the ability to establish causal relationships between variables, despite efforts to control for confounding factors. Future research could benefit from longitudinal or interventional approaches to explore causality further. Lastly, the lack of diversity in the FHS cohort may limit the applicability of findings to broader populations. Future studies should strive to include more diverse cohorts to enhance generalizability and reduce potential biases.

Future Directions

Large cohorts with multiethnicities should be used to confirm that the DCT and other digital tools detect CMB and similar pathologies in different brain regions and can serve as a cost-effective screening tool to better identify people at risk earlier in the preclinical stages of the disease [ 11 ]. More importantly, user-oriented assessment devices such as the DCT may promote objectivity and equity within public health research, especially in underserved populations.
