“My supervisor said my dissertation needs to be more critical. What does that actually mean?”
This is one of the most common questions postgraduate students ask after receiving dissertation feedback. The phrase “be more critical” does not mean simply disagreeing with researchers or adding negative comments to every paragraph. It means demonstrating that you can evaluate, compare and interpret academic evidence rather than simply describe it.
For students writing a literature review, methodology, discussion or other dissertation chapters, critical thinking is essential for developing a convincing academic argument.
What Does “Be More Critical” Mean in a Dissertation?
Critical writing involves examining the strengths, weaknesses, assumptions, limitations and implications of existing research.
A descriptive sentence might say:
Smith (2024) found that artificial intelligence improved productivity among small businesses.
A more critical approach could consider the research design, sample, context and whether the findings can be generalised to other businesses.
The key difference is that descriptive writing tells the reader what a researcher found, while critical writing explains how convincing that evidence is and why it matters to your research.
1. Stop Writing One Study at a Time
One reason supervisors say “be more critical” is that students structure their literature reviews as a sequence of summaries.
For example:
- Study A found X.
- Study B found Y.
- Study C found Z.
This demonstrates reading, but not necessarily critical analysis.
Instead, bring studies into conversation with one another. Identify whether their findings agree, contradict each other or differ because of their samples, methods, theories or research contexts.
2. Compare Different Perspectives
Critical writing often involves comparison.
Ask questions such as:
- Do researchers agree on this issue?
- Why do their findings differ?
- Which argument has stronger evidence?
- Are different theories explaining the same phenomenon?
- Does the research apply to the population being studied?
These questions help transform a literature review from a summary into an analytical discussion.
3. Evaluate Research Methods
Being critical does not mean criticising researchers personally. It means evaluating whether the research methods were appropriate for answering the research question.
For example, consider:
- Was the sample sufficiently large?
- Was the sample representative?
- Was the study conducted in the appropriate context?
- Were the variables measured reliably?
- Were there methodological limitations?
- Could another research method have produced different results?
This type of evaluation demonstrates academic judgement.
4. Question Generalisations
A study may produce an interesting finding, but that does not automatically mean its conclusion applies everywhere.
For example, research conducted among employees in one organisation may not necessarily represent employees across an entire industry.
Critical writing therefore considers context and transferability rather than accepting every finding at face value.
5. Explain Why the Evidence Matters
Another important part of critical writing is interpretation.
After presenting evidence, explain what it means for your research.
Instead of ending a paragraph with a citation, ask:
So what?
Why is this finding important? Does it support your argument? Does it reveal a contradiction? Does it expose a limitation in previous research? Does it help establish your research gap?
This is where your own academic reasoning becomes visible.
6. “Critical” Does Not Mean “Negative”
A common misconception is that critical writing means finding something wrong with every article.
It does not.
You can write positively about high-quality research while still being critical. For example, you might explain that a study uses a strong research design but has limited generalisability because of its specific geographical context.
The objective is balanced evaluation, not constant criticism.
Descriptive vs Critical Writing
A simple way to understand the difference is:
Descriptive:
“Several studies found that employee motivation influences job satisfaction.”
Critical:
“Although several studies report a positive relationship between employee motivation and job satisfaction, the strength of this relationship varies across organisational contexts. Differences in measurement approaches and sample characteristics may partly explain these inconsistent findings, suggesting that the relationship requires further investigation in the context examined by the present study.”
The second version does more than report findings. It compares evidence, identifies variation and explains why further research may be necessary.
How Can You Respond to “Be More Critical”?
When revising your dissertation, do not simply add more citations. Instead, review each major paragraph and ask:
- What is the main argument?
- What evidence supports it?
- Are there contrasting findings?
- What are the limitations of the evidence?
- How reliable or relevant is the evidence?
- What does the comparison reveal?
- How does this connect with my research question?
If your paragraph answers these questions where appropriate, it is more likely to demonstrate genuine critical analysis.
Final Takeaway
When your supervisor says “be more critical,” they usually want to see more than evidence that you have read the literature. They want to see your ability to evaluate evidence, compare perspectives, recognise limitations, identify contradictions and develop a reasoned academic argument.
Critical writing is therefore not about writing more. It is about thinking more deeply about the evidence you already have.

FAQs
What does “be more critical” mean in academic writing?
It means evaluating and interpreting evidence rather than simply describing what previous researchers have said.
Does critical writing mean disagreeing with researchers?
No. Critical writing involves balanced evaluation. You can identify both strengths and limitations in previous research.
How can I make my literature review more critical?
Compare studies, discuss conflicting findings, evaluate methodologies, identify limitations and explain how the literature relates to your research question.
Why does my supervisor say my writing is too descriptive?
Your writing may be reporting individual studies without sufficiently comparing, evaluating or synthesising their findings.
How do I turn descriptive writing into critical writing?
After presenting evidence, ask questions such as “How convincing is this evidence?”, “Why do these findings differ?” and “What does this mean for my research?” Then incorporate your analysis into the paragraph.
