About Critical Thinking
Critical thinking examines how conclusions follow from evidence, including claims, assumptions, arguments, inferences and relevant facts. Questions ask you to identify hidden assumptions, distinguish strong from weak evidence, assess cause and effect, recognise common reasoning errors, and decide which statement strengthens or weakens an argument.
