Test your critical thinking

The test uses nine skills, the same nine named in the focus menu. Logical fallacies: whether a step matches a named mistake, such as a straw man or a false dilemma, rather than a conclusion you dislike. Cognitive biases: whether a judgement is being tugged by a habit the library files, such as confirmation, availability, anchoring, or framing. Evaluating arguments: whether the reasons offered actually support the conclusion. Identifying assumptions: the claim the step needs and does not state. Fact versus opinion: which part could be checked, and which part is a verdict, without pretending that every opinion is empty. Interpreting an argument: what this passage is doing, not what a louder slogan near it usually means. Applying a principle: using a rule the question gives you on a new case, including when the result is inconvenient. Numbers and chance: percentages, risk, samples, averages and charts. Evidence and sources: studies, headlines, experts, photos and quotations, and how to weigh them.

You can sit all nine or one of them. Difficulty is mixed, or foundation, intermediate, or advanced. The questions are the bank this site already uses.

Length is 10, 20, or 30 questions. Timing is untimed, 45 seconds each, or 25 seconds each. Untimed is the ordinary way to learn, because the explanation after each answer is the point of the sitting. A clock, when you choose one, is per question. It does not add a second, overall limit. If the skill you picked has fewer questions than the length, the next screen says so and the test uses all of them. This practice test has no pass mark. Mastery Tests and the Certificate Test pass at 80%. This page will not invent a percentage that “most people” reach.

The test costs nothing and does not ask you to sign in. The question bank is fetched when you press Start, not with this page. Your score, the review of each answer, and the daily streak are stored in this browser. Clearing the site’s data clears them. A higher number means more of these questions right, at the difficulty and length you picked. It is not a qualification, and it is not a comparison with other people, because other people’s scores are not here.

After a sitting you can read each question with your answer, the correct answer, and the explanation, then retry the ones you missed. That review is the same local record. The streak on the home page is a habit around the short daily three, not a grade for this longer test.
