Cognitive Reflection Test

Test your ability to resist intuitive-but-wrong answers. Based on the Cognitive Reflection Test — one of the most-cited cognitive tests ever created. How It Works: - You'll see 15 problems, one at a time - Every problem has an answer that "feels right" but is actually wrong - The correct answer requires a moment of reflection - You choose from 4 options The Science: Psychologist Shane Frederick developed this test in 2005 to measure whether people can override their intuitive System 1 thinking and engage deliberate System 2 reasoning. It's one of the shortest cognitive tests ever created — but one of the most predictive. Why It Matters: CRT scores predict performance on a huge range of real-world outcomes — from financial decision-making to belief in conspiracy theories to willingness to take risks. The core skill measured is the ability to notice when your gut is wrong. Tips: When you see an answer that jumps out immediately, pause. That's usually the trap. Ask yourself: does this hold up if I check the math? Benchmarks: Average adult scores 5-7 out of 15. Scores above 10 are excellent. Above 13 is exceptional.
