Description vs critical analysis: what "be more critical" actually means
The most common feedback on university essays is "too descriptive, not critical enough". Here's the real difference, with a worked example, and how to turn description into analysis.
If you have had an essay returned with "too descriptive", "needs more critical analysis", or "you are describing, not arguing" in the margin, you are not alone — it is the single most common piece of feedback in university marking. The frustrating part is that it rarely comes with an explanation of what to do differently.
Here is the difference, in plain terms, with an example you can copy the logic from.
The core difference
Description tells the reader what happened, what a source says, or what the data shows. It is accurate, and it is necessary — but on its own it earns middle marks at best.
Critical analysis tells the reader what it means: why sources disagree, which evidence is stronger and why, what a finding implies, what a study missed. It is the difference between reporting the pieces and explaining how they fit.
A useful way to hear it: description answers what? Analysis answers why? and so what?
A worked example
Watch what happens to the same three sources.
Descriptive version:
Smith (2019) says social media harms wellbeing. Jones (2021) says it does not. Patel (2022) found mixed results.
Everything there is true. But it is a list. The reader learns what three people concluded and nothing about why, or what to make of the disagreement. This is the paragraph that gets "too descriptive" in the margin.
Analytical version:
Smith (2019) and Jones (2021) disagree because they measure wellbeing differently — one by self-report, the other by clinical screening. Patel's (2022) mixed findings follow directly from combining both instruments.
Same three sources. But now you are explaining why they conflict, and you have turned an apparent contradiction into a coherent point. That is what your rubric means by "critical".
Notice you did not need extra research. The analysis came from interrogating what you already had.
Four moves that turn description into analysis
Whenever you have written a descriptive sentence, try adding one of these.
Ask why. Why does this source argue that? Why do two studies reach opposite conclusions? The answer is usually your analytical point.
Compare, do not just collect. Instead of summarising sources one after another, put them in conversation: where do they agree, where do they clash, and what explains the clash?
Weigh the evidence. Not all findings are equal. A study of 30 people and a study of 30,000 should not be quoted as if they carry the same weight. Say which is stronger, and why.
Answer "so what". After a point, ask what follows from it for your argument. If nothing follows, the point may not belong in the essay.
Signposting language that pushes you into analysis
The words you reach for shape the thinking. Descriptive writing leans on states, says, describes, shows. Analytical writing leans on:
- This suggests… / implies… / indicates…
- However, this is complicated by…
- A stronger explanation is…
- This matters because…
- The difference stems from…
If your paragraphs never contain phrases like these, you are probably still describing.
A quick test
Take any paragraph and highlight every sentence that only reports what a source said. If most of the paragraph is highlighted, it is description. Add the why and the so what, and you have written analysis.
