“Be more critical” is one of the most common pieces of feedback UK students receive, yet it is rarely explained. Critical writing is how you put critical thinking on the page: analysing and evaluating rather than simply describing. This guide shows you the difference, how to move from description to analysis, and the language that signals critical writing to your marker.
Descriptive vs Critical Writing
Descriptive writing tells the reader what happened or what a source says — it reports facts. Critical writing goes further: it examines why something matters, how strong the evidence is, how ideas compare, and what the implications are. Some description is necessary to set the scene, but higher marks come from spending most of your words analysing and evaluating. A common trap is writing a detailed summary and mistaking it for analysis.
How to Move From Description to Analysis
A simple test is to keep asking “so what?” of every point. Once you have stated a fact or a source’s claim, push on: why is it significant, how does it support your argument, what are its limitations, and how does it relate to other evidence? Turning “Smith found X” into “Smith found X, which suggests… although this is limited by…” transforms description into analysis.
Building a Critical Argument
Critical writing is organised around an argument, not a list of facts. Make a clear claim, support it with evidence, evaluate that evidence, consider alternative views or counter-arguments, and reach a reasoned judgement. Weighing competing perspectives — and explaining why you find one more convincing — shows the independent thinking that examiners reward. Each paragraph should advance your argument rather than simply add more information.
The Language of Critical Writing
Certain phrases signal that you are analysing rather than describing. Use evaluative language such as “this suggests,” “a strength of this approach is,” “however, a limitation is,” “in contrast to,” “this is significant because” and “on balance.” Cautious, hedged language — “this may indicate” rather than “this proves” — also shows academic maturity. These phrases are not a formula to paste in, but markers of the analytical moves your writing should be making.
A Before-and-After Example
Descriptive: “Smith (2023) found that remote workers reported higher productivity.” Critical: “Smith (2023) found that remote workers reported higher productivity; however, because the data were self-reported, they may reflect perception rather than measured output. This limitation matters when comparing Smith’s findings with Jones (2024), whose objective measures showed no clear difference.” The second version evaluates the evidence and connects it to other research — that is critical writing.
Frequently Asked Questions
What is critical writing?
Critical writing analyses and evaluates evidence and arguments rather than just describing them. It weighs strengths and weaknesses, compares views and reaches a justified conclusion.
How do I make my writing more critical?
Keep asking “so what?” after each point, evaluate the strength of your evidence, consider alternative views and limitations, and use evaluative language such as “this suggests” and “however.”
Why does my feedback say “too descriptive”?
It usually means you are reporting information without analysing it. Spend fewer words summarising and more explaining why it matters, how strong it is, and how it supports your argument.
