About This Topic

Critical thinking is the disciplined evaluation of claims, evidence and arguments to reach well-reasoned judgments instead of accepting ideas at face value. Questions distinguish facts from opinions, identify premises and conclusions, and ask for the difference between necessary and sufficient conditions. Many items name logical fallacies such as ad hominem, straw man, false dilemma and slippery slope, or cognitive biases including confirmation bias, anchoring and availability. Decision-making questions cover cost-benefit analysis, decision matrices and weighing risk under uncertainty, along with the Socratic method of probing assumptions through questioning and the idea of epistemic responsibility for how beliefs are formed.

Below are 30 practice questions from a pool of 210 Critical Thinking & Decision Making MCQs, one of 16 topics in Problem Solving & Analytical Skills. Each shows the correct answer with an explanation; when you are ready, take a timed quiz to test recall under exam conditions.
