How to Write a Literature Review Conclusion (With Examples)

The conclusion of a literature review carries more weight than its length usually suggests. It is the section where you demonstrate that you have not just summarised existing research but genuinely understood it well enough to identify exactly where it falls short - and that gap is what justifies your own research existing at all. This guide covers what a strong conclusion actually does, with real examples.

What a Literature Review Conclusion Needs to Do

A literature review conclusion has three specific jobs, and a genuinely strong conclusion does all three rather than just the first: summarise what the body of literature collectively shows, synthesise the overall state of knowledge (not just recap each theme separately), and explicitly identify the specific gap your own research addresses.

The third job is the one most often missing or done weakly, and it is arguably the most important, since it is what connects your literature review to the rest of your dissertation or paper. A conclusion that summarises well but never clearly states the gap leaves the reader wondering why your specific research question matters.

A Weak Example

"In summary, this review has examined the literature on remote work productivity. Several studies found that remote work increases productivity, while others found mixed or negative effects. Further research is needed in this area."

This conclusion technically summarises the review's content, but it does three things poorly: it does not synthesise the actual pattern in the findings (why do studies disagree - what specifically differs between the studies that found positive versus negative effects?), it does not identify a specific gap (which "further research" - anything could satisfy that vague sentence), and it gives the reader no real sense of what has actually been learned.

A Strong Example, Same Topic

"Taken together, the reviewed literature reveals that remote work's effect on productivity depends heavily on how productivity is measured: studies relying on self-reported employee data consistently find positive effects, while studies using objective output metrics show more mixed results. This pattern suggests the disagreement in the literature may reflect a methodological limitation rather than a genuine effect, since self-report measures are particularly susceptible to social desirability bias in this specific context. No study to date has directly compared self-reported and objectively measured productivity within the same remote-work sample, which is precisely the gap this research addresses."

Notice what changed: the conclusion identifies a genuine pattern across the literature (not just "some studies found X, others found Y"), offers an interpretation of why that pattern exists (a specific methodological explanation), and names a precise, specific gap - not "more research is needed" but a defined, addressable gap that the writer's own study fills directly.

A Second Example: A Shorter, Undergraduate-Level Conclusion

Not every literature review needs the full depth of the example above - a shorter, coursework-level review can still do all three jobs concisely:

Weak: "This review has looked at different theories of motivation in the workplace. Each theory has strengths and weaknesses. More research could explore this further."

Strong: "The theories reviewed here largely agree that autonomy and mastery are central to workplace motivation, but they diverge sharply on the role of financial incentives - a divergence this review has traced to differing underlying assumptions about whether motivation is primarily intrinsic or extrinsic. This unresolved theoretical tension is directly relevant to the case study analysed in the following section, which examines a workplace where both intrinsic and extrinsic incentive structures operate simultaneously."

Even at a shorter length, the strong version identifies a genuine point of disagreement, explains its underlying cause, and connects it forward to the rest of the paper - all three jobs, done concisely.

Common Mistakes in Literature Review Conclusions

Introducing new sources or new information. A conclusion should synthesise what has already been discussed in the body, not introduce a new study or a new point that has not appeared earlier in the review. If a source genuinely belongs in the conclusion's argument, it needed to be discussed in the body first.

Restating the introduction rather than synthesising the findings. A weak conclusion sometimes essentially repeats the review's opening framing without actually reflecting the specific content and patterns that emerged across the body. A strong conclusion demonstrably engages with what was actually found, not just what was originally planned to be covered.

Vague calls for "more research" without specificity. As shown in the weak examples above, "more research is needed" is not a gap statement - it is a placeholder for one. A genuine gap statement names what specifically is missing: an unstudied population, an untested methodological comparison, an unexamined context, or an unresolved theoretical tension.

Treating the conclusion as optional or an afterthought. Given how directly the conclusion connects the literature review to the justification for your own research, under-investing time in this section - writing it hastily as a formality - undermines the logical structure connecting your entire study together.

Length and Placement

A literature review conclusion is typically shorter than the body - often just a few paragraphs even for a lengthy review - but its brevity does not mean it should be written with less care. If your literature review is a standalone chapter within a larger dissertation, this conclusion often flows directly into your methodology chapter, since the gap you identify here is precisely what your methodology is designed to address; keeping this connection explicit in your writing (referring forward to how your study will address the identified gap) strengthens the overall coherence of your dissertation.

When Your Literature Review Genuinely Has No Gap Yet

Occasionally, students working on a preliminary literature review discover that the existing literature already answers their intended research question reasonably well, leaving no obvious gap to fill. This is a genuinely useful discovery to make early, since it means the research question itself needs refining before you can write a convincing conclusion - rather than trying to manufacture an unconvincing gap statement to fit a question the literature has already settled. If your conclusion is proving difficult to write because you cannot honestly identify a real gap, that difficulty is worth taking seriously as a signal about your research question, not just about your writing.

Getting Support With Your Literature Review Conclusion

Writing a conclusion that genuinely synthesises rather than summarises, and identifies a precise rather than vague gap, is one of the more difficult parts of a literature review to get right without feedback. If you want a second opinion on whether your conclusion does all three jobs effectively, CampusScribe's editors review literature review conclusions and full chapters for exactly this kind of analytical strength.
