About This Test
Critical thinking is judging arguments by weighing evidence, assumptions, and inference quality.
Critical thinking asks you to evaluate an argument rather than simply solve a puzzle. In this test you read short passages, claims, or scenarios and then decide whether a stated conclusion truly follows, whether an assumption is being taken for granted, and how strongly a piece of evidence supports a position.
Typical item types mirror the Watson Glaser tradition: recognising valid inferences, spotting unstated assumptions, judging deductions, deciding whether a conclusion is warranted, and rating the strength of competing arguments. You must separate fact from opinion, notice when a source is biased or irrelevant, and resist conclusions that merely sound persuasive. The focus is on the reasoning itself, not on your prior knowledge of the subject being discussed in the passage.
Employers value critical thinking because most senior work involves deciding under uncertainty rather than repeating a fixed procedure. Law firms, consultancies, financial analysts, and graduate management schemes use tests in this family, and the Watson Glaser assessment is especially common in legal recruitment. Journalists, researchers, policy analysts, and clinicians all rely on the same core habit: checking whether a claim is actually supported before acting on it.
Strong critical thinkers ask what evidence would change their mind, notice loaded language, and distinguish correlation from cause. Because misleading arguments appear constantly in reports, media, and negotiations, this skill protects you from being persuaded by confident but hollow reasoning, which is why it features so widely in professional selection.
To perform well, read each passage on its own terms and answer only from the information given, never from what you personally believe to be true. Identify the exact conclusion first, then trace which statements are offered to support it and whether any gap has been bridged by an unstated assumption. Watch for absolute words such as all or never, which often make an inference too strong to accept.
Treat every argument as a claim to be tested rather than a fact to be memorised. A high score suggests you evaluate evidence carefully and resist flawed persuasion; a lower score points to a tendency to accept conclusions that feel right without checking whether the supporting reasoning genuinely holds together.
What This Test Measures
Assumption spotting
Recognising the unstated ideas an argument quietly takes for granted, so you can see whether a conclusion still holds once those hidden premises are questioned.
Inference strength
Judging how firmly the evidence supports a claim, and telling a conclusion that truly follows apart from one that merely sounds persuasive on first reading.
Evaluating arguments
Weighing competing arguments on the same issue, deciding which are strong and directly relevant, and dismissing points that are trivial or beside the question.
Fact versus opinion
Separating what a source establishes as evidence from what it merely asserts, and noticing loaded language, bias, or irrelevant detail dressed up as proof.
