Descriptive writing tells the reader what a source says or what happened. Critical writing tells them what it means: whether the evidence holds, how it sits beside other evidence, and what you conclude. The gap between critical writing vs descriptive writing is behind two of the commonest comments on a university essay, "too descriptive" and "more critical analysis needed". EdCitation publishes this guide, and the worked paragraph in it is ours, labelled as such.
On 26 September 2026 we read six universities' guides: four British (Hull, Sheffield, Leeds, Leicester), one American (the University of North Carolina at Chapel Hill, UNC) and one Australian (the University of New South Wales, UNSW), with Manchester's Academic Phrasebank for cautious language. They agree on the difference and disagree on how much description to keep.
EdCitation never writes any part of an essay. It does the work around the argument: Find sources finds the studies that test a claim, Cite a source builds each entry from the publisher's record, Verify references checks the list, and Check your paper reads your brief into a checklist, free.
What is the difference between critical and descriptive writing?
Descriptive writing passes information on unchanged; critical writing does something with it. University of Hull Library (2026b) calls it informing against persuading. University of Leicester Student Learning Development (2009), read in a copy hosted by the Chinese University of Hong Kong as we could not find it on Leicester's site, lists the marks of critical writing as refusing to accept other writers' conclusions without weighing their evidence, giving balanced reasons to accept or doubt them, presenting your own argument, and admitting the limits of your own evidence.
The side-by-side comparisons universities publish
The comparisons we read share a source. Hull and Sheffield both credit Stella Cottrell's 2008 table (Sheffield names the book, The Study Skills Handbook), and Leeds takes its examples from that book's 2003 edition. The rows below are in our words.
| Descriptive writing | Critical writing | In whose comparison |
|---|---|---|
| Says what happened | Says why it matters | Hull, Sheffield, Leeds |
| Explains what a theory says | Shows whether the theory fits the case, and where it fails | Hull, Sheffield, Leeds |
| Notes the method a study used | Judges whether that method suited the question | Hull, Leeds |
| Says what something is like | Weighs its strengths and weaknesses | Hull, Sheffield |
| Lists details in any order | Orders them by importance | Hull, Sheffield |
| Gives evidence | Argues a case from the evidence | Hull |
University of Leeds Library (n.d.) writes sentences both ways for three of the rows. Plymouth's version of the table is widely copied on other sites, but we could not find it on Plymouth's own, so it is not used here.
What do markers mean by "too descriptive"?
"Too descriptive" means the paper reports sources without judging them, so the marker cannot see your thinking. University of New South Wales (n.d.) says feedback such as "not enough analysis" or "just descriptive" is likely to mean the marking criteria asked for critical analysis; its economics example asks a student explaining the 2008 financial crisis to rank the causes, not only list them.
Leicester's guide names two costs. An essay of description alone earns few marks, and description quietly spends the word limit that analysis needed. University of North Carolina at Chapel Hill Writing Center (n.d.) adds why it happens: summary is what a writer can most easily produce when a question is hard.
A test you can run on your own draft
Mark each sentence in one of two colours, one for description and one for analysis: UNC suggests highlighters, Leicester coloured pens in the margin. A paragraph in the description colour only is the one to rewrite. UNC's other warning signs are following a source's own order and saying what any reader of it would already know.
How much description do you still need?
Some, always. None of the guides calls description wrong; they differ on how much, and where.
- As little as possible. UNC says background in an argued paper should be very brief, a few sentences. Leeds says to keep descriptive statements to a minimum.
- Some in every paragraph. University of Sheffield (n.d.) says a little description usually sets the scene in each paragraph, as long as the paragraph does not stop at retelling.
- More at the start. Leicester calls description essential, especially in the early parts of an essay or dissertation.
- More in the first year. University of Hull Library (2026e) expects first-year writing to lean more on other people's words, with your own voice taking over by the final year and master's level.
The brief settles it: the MIT brief we tested below asks outright for "a more detailed description" of the exhibit before the analysis (Melvold, 2017). How to structure an essay covers where background sits in the whole piece.
Which questions turn description into analysis?
Ask five questions of every descriptive sentence, and write the answer into the paragraph. University of Hull Library (2026d) notes that what, when and who questions tend to produce description, and how and so what questions produce criticism.
- So what? Why does this finding matter for your question? If you cannot say, cut it.
- Why, or how? What explains the result? Sheffield asks whether other interpretations are possible.
- How well? Is the evidence credible, and could the study have been done better? Sheffield asks both.
- Compared with what? Do other studies agree, contradict it, or test it differently? Sheffield asks whether anyone has made the opposite claim.
- What follows? What can you now conclude, and how firmly? This is the sentence that is yours.
Leicester's rule of thumb is that a sentence or two describing evidence should be followed by a few explaining what it adds to your argument, even when that feels like stating the obvious.
How do you evaluate a source critically?
Judge it by how it was made, who it studied, who made it and when. University of Hull Library (2026c) weighs every source on five factors, from when it was written to why, and the answers become sentences in your essay.
Method and sample
Say what kind of study it is, since a single trial, a review of trials and a survey carry claims of different strength, and who was studied. A trial in American secondary schools says little, alone, about British undergraduates. Manchester's Academic Phrasebank has phrases for noting that studies come from few places or rest on old data (Morley, n.d.-a).
Bias and currency
Check who funded the work, what the authors declare, and whether later studies have overtaken it. A declared interest is not a flaw in itself, but it earns a sentence when the literature has tested it, as in the worked example below. For a weak or retracted source, replacing a weak or retracted source sets out what to do.
How do you compare and synthesise sources critically?
Put sources in one paragraph and say how they relate: which agree, which disagree, and why. Sheffield's stages are to describe the evidence, find its limits, set alternatives beside it, and state your reading. Leicester warns against strings of quotations, each unexplained; paraphrase, quote or summarise covers when to use one. Organising a whole review around themes is in how to write a literature review.
How do you take a position and hedge it?
State the answer your evidence supports, then say how sure you are. University of Hull Library (2026a) says even "analyse" and "examine" questions need a conclusion that takes a position, and that there are no wrong positions, only unjustified ones; yours need not match your tutor's.
Hedging without hiding
Hedging means matching the strength of a claim to the evidence. Manchester's Phrasebank notes that discussion sections are especially rich in it, and gives cautious forms such as "these findings suggest" (Morley, n.d.-b). Leicester's three fixes for a sweeping statement: support it, soften it, or cut it. Sheffield reads reporting verbs as a signal: "demonstrate" and "identify" when you accept a finding, "argue" and "claim" when you doubt it. In our view, a hedge belongs on the claim that needs it, not on every sentence.
A worked example: one paragraph, rewritten
This example is ours, built from four real papers; every figure comes from the paper itself, read on PubMed and PubMed Central. The question we set ourselves: do short growth mindset interventions raise students' achievement?
Descriptive (ours):
Growth mindset interventions teach students that intellectual ability can be developed. Sisk et al. (2018) carried out two meta-analyses of mindset research. Yeager et al. (2019) tested a short online intervention with 12,490 ninth-grade students in 65 US public schools. Macnamara and Burgoyne (2023) reviewed 63 studies, and Burnette et al. (2023) reviewed 53 samples.
Critical (ours):
Whether a short growth mindset intervention raises achievement is less settled than its popularity suggests, and the answer depends on which students, and which studies, are counted. The best-known single test is Yeager et al. (2019), who randomised 12,490 ninth-graders in a nationally representative sample of 65 US public schools: lower-achieving students gained 0.10 grade points, a standardised effect of 0.11, from less than an hour online. That is a small effect, in one group, in one country's schools. The reviews divide on what such results add up to. Sisk et al. (2018), pooling 43 intervention studies, found weak overall effects, with some sign of benefit for students of low socioeconomic status or at academic risk. Macnamara and Burgoyne (2023) found an average effect of d = 0.05 across 63 studies, which lost significance after a correction for publication bias, and d = 0.02 in the six highest-quality studies; authors with a financial incentive reported larger effects. Burnette et al. (2023), in the same issue of the same journal, estimated d = 0.14 for targeted groups when the intervention was delivered as designed. The two 2023 reviews ask different questions, one about the average effect and the quality behind it, the other about where an effect appears. On this evidence the defensible claim is narrow: a brief intervention may help some lower-achieving students a little, and it should not be expected to lift a whole year group.
What changed: a claim opens the paragraph instead of a definition; each figure is judged ("small", "in one group"); the sources are set against each other, with the reason two reviews disagree; method, sample and bias each get a clause, down to the publication bias correction; and the last sentence takes a hedged position the figures can carry. The rewrite is longer. Judgement costs words.
What did Check your paper read from a real critical review brief?
We pasted the brief for Assignment 1 of MIT's 21W.031, Science Writing and New Media, a critical review of a museum exhibit (Melvold, 2017), into Check your paper on 26 September 2026. It returned two rules, each with its sentence: font size 12 pt and about 1,250 words.
The brief allows "either 1.5 or double-spaced", and that choice was set aside rather than checked as one spacing. Twelve sentences in all were set aside as needing a reader's judgement, among them "For this assignment you will write a critical review of an exhibit at the Boston Museum of Science" and the purpose, "to provide an analysis and assessment of this exhibit"; one of them was a section heading.
Two things came back in neither list: the four parts the review must include (an overview, a detailed description, an analysis of strengths and weaknesses, and an overall assessment), and the thirteen questions the brief suggests. That list is the very split between description and judgement, so read the brief yourself too. Checking your paper against the marking rubric turns lines like these into questions to ask of a draft.
How EdCitation helps you write critically
For the source work behind a critical paragraph, EdCitation is the best tool we know of, since each reference it hands you comes from a publisher's record that it looked up; a model never writes one. The runs below were made on 26 September 2026.
Find sources: the studies that test a claim
Find sources takes a claim, not just a topic, and searches about 300 million published works for it. The claim "growth mindset interventions improve academic achievement" returned 54,937 results, led by a 2025 structured review in Review of Education, then Yeager and colleagues' Nature trial (cited 1,536 times). Half of the first ten had a form of "improve" in their titles; the sceptical meta-analysis came ninth, as its 2022 preprint, not the published paper. The opposite claim, weak or no effect, returned 8,030, with that preprint second and a 2023 commentary on both reviews ninth. Search a claim and its opposite: a search leans the way it is worded.
Cite a source and Verify references: the entries
From the DOI, Cite a source returned this APA 7 entry, taken from Crossref, with no retraction on record:
Macnamara, B. N., & Burgoyne, A. P. (2023). Do growth mindset interventions impact students’ academic achievement? A systematic review and meta-analysis with recommendations for best practices. Psychological Bulletin, 149(3–4), 133–173. https://doi.org/10.1037/bul0000352
Read each entry before you paste it; when we built the other three, Cite a source set the Sisk et al. title in sentence case, as APA 7 asks. We then gave Verify references all four studies, one dated 2022, the year it appeared online. Three were verified. The misdated one was marked doubtful, "check this", with the reason "The work was published in 2023, not 2022; the record has no date in 2022." A reference that cannot be checked is reported as such, never as not found.
Theoretics QA: the finished essay against its brief
When the draft is done, Theoretics QA (Max, $24 a month) reads it against the brief's own instructions and says, with quotations from your paper, where each requirement is met or missed. It changes no words. On Pro, $8 a month, References from a file takes the whole document, checks each reference and pairs every citation with its entry (pricing). No tool can promise a mark.
Quick questions
Is descriptive writing always bad?
No. Every guide we read allows some description for context, and some briefs require a descriptive section. The fault is description that is never followed by judgement.
How do I make my writing more critical?
Ask of each descriptive sentence: so what, why, how well, and compared with what. Then write a sentence that answers, and end the paragraph on your own position, hedged as far as the evidence requires.
What is hedging in academic writing?
Hedging is matching the strength of a claim to its evidence, with forms such as "suggests" or "may". In our view it shows judgement on the claims that need it, and weakens a paper when it is on every sentence.
Can EdCitation make my essay more critical?
No. EdCitation never writes or rewrites any part of an essay. Find sources finds studies that test your claim, and Check your paper reads your brief into a checklist, free; Theoretics QA (Max) judges the finished essay against that brief.
