The conclusion is the last thing your reader, reviewer, or examiner reads — it shapes their final impression of your work. A weak conclusion undersells your contribution; an overconfident one damages your credibility. A strong conclusion does three things clearly: it summarises what you found, explains why it matters, and points to what comes next. This guide gives you the tools to write all three with confidence.
Structure of a Research Paper Conclusion
| Component | Content | Approx. Length |
|---|---|---|
| Opening summary | Restate the research objectives and what you did — briefly | 2–3 sentences |
| Key findings summary | The 2–4 most important findings — concisely, not repeating the Results section | 3–5 sentences |
| Significance / Contribution | What these findings add to theory, practice, or policy | 3–4 sentences |
| Limitations | Brief, constructive acknowledgement of constraints | 1–2 sentences |
| Future research | What should be investigated next, and why | 2–3 sentences |
| Closing statement | Memorable final sentence reinforcing broader significance | 1–2 sentences |
Before and After: Weak vs Strong Conclusions
Weak Conclusion Example
"In conclusion, this study examined the relationship between social media use and academic performance among university students. The results showed that there was a negative correlation. Future research could look at other factors. This study had limitations including the small sample size."
Problems: repetitive, vague, no contribution articulated, ends on a limitation, no implications stated.
Strong Conclusion Example
"This study investigated the relationship between social media use patterns and academic performance among undergraduate students in Indian universities, addressing a gap in the literature on technology use in non-Western higher education contexts. The findings reveal that passive social media consumption — browsing without active engagement — is negatively associated with GPA outcomes, while active, academically-focused social media use (such as study group participation) shows no significant negative effect. These results extend [Author]'s (2021) model by distinguishing use patterns that prior studies had treated as uniform, offering a more nuanced theoretical framework for understanding digital technology's educational impact. For educators and institutions, the findings suggest that digital literacy programmes targeting passive consumption habits — rather than blanket social media restriction — may be the most effective intervention. Future research should employ longitudinal designs to establish directionality and examine disciplinary differences in these relationships. As social media becomes increasingly embedded in academic environments, understanding the mechanisms behind its effects on learning will grow only more critical."
Common Conclusion Mistakes
- Starting with 'In conclusion' — hackneyed; find a more engaging entry point
- Introducing new information — everything in the conclusion must have been discussed in the paper body
- Repeating the abstract — the conclusion should synthesise, not replicate
- Over-claiming — "this study definitively proves" is almost never warranted
- Ending on a limitation — end on your contribution, not your weakness
- No future research direction — reviewers expect this; it shows intellectual modesty and forward thinking
Mirror Your Introduction
A well-crafted conclusion answers the questions the introduction raised. Read your introduction, then your conclusion — do they match? The introduction says 'we don't know X'; the conclusion should say 'we now know X, and this means Y for the field'. This mirror structure gives your paper a satisfying intellectual coherence that reviewers and examiners notice.

Frequently Asked Questions

A research paper conclusion should include: (1) Brief summary — a concise restatement of the research objectives and key findings (not a repetition of the Results section); (2) Significance — what your findings mean and why they matter for theory, practice, or policy; (3) Contributions — what this study adds to the existing body of knowledge; (4) Limitations — a brief acknowledgement of the study's constraints (if not already covered in Discussion); (5) Recommendations — practical implications for practitioners, policymakers, or future researchers; (6) Future research directions — what questions remain unanswered and what should be studied next; (7) Closing statement — a memorable final sentence that reinforces the broader significance of the work. Do NOT introduce new arguments, data, or citations in the conclusion.
Conclusion length depends on paper length and journal requirements: Short journal articles (4,000–6,000 words): conclusion typically 300–500 words. Standard journal papers (6,000–8,000 words): 400–700 words. PhD thesis chapter conclusions: 400–800 words. PhD thesis final chapter (overall conclusion): 1,000–3,000 words — much longer because it synthesises all chapters and discusses the overall contribution. Review articles: 500–1,000 words. The conclusion should be proportional — typically 5–10% of the total paper. Avoid padding with excessive repetition; but also don't rush through it. The conclusion is the section editors and reviewers read most carefully after the abstract.
Discussion: interprets and explains findings in relation to the research questions and prior literature; explores why findings are what they are; compares to other studies; addresses limitations in depth. Conclusion: synthesises and summarises the overall contribution of the study; focuses on what was achieved and what it means for the field; looks forward (future research, implications); does not re-interpret data in detail. Some journals combine Discussion and Conclusion into one section; others require separate sections. In PhD theses, most universities require both. If combined: begin the section with interpretation (Discussion) and end with synthesis and forward-looking statements (Conclusion).
Do NOT include in a research conclusion: (1) New data or evidence not previously presented in the paper; (2) New citations that haven't appeared in the paper body; (3) New arguments or interpretations not developed in the Discussion; (4) Lengthy repetition of the Results section — summarise, don't repeat; (5) Vague, unsupported generalisations that go far beyond your data; (6) Over-claiming (e.g., 'This study proves conclusively...'); (7) Apologies for your limitations that undermine your contribution (mention limitations briefly, constructively); (8) Clichéd openers like 'In conclusion, this paper has shown...' — find a more engaging summary statement.
The final sentence of your research paper is your last word to the reader — make it count. Strong closing strategies: (1) Broaden out — from your specific findings to the bigger picture: 'These findings suggest that [specific finding], with important implications for how we understand [broader phenomenon] in [field/context]'; (2) Call to action — especially for applied research: 'If these findings inform future policy interventions, [specific positive outcome] may become achievable for [population]'; (3) Forward-looking — point to the research frontier: 'As [technology/phenomenon] continues to evolve, the questions raised by this study will only grow in importance'; (4) Reinforce the contribution: 'By demonstrating [X], this research provides both [theoretical advance] and a practical foundation for [applied development]'. Avoid trailing off with a limitation — end on a contribution, not an apology.
