Cognitive Reflection Test
Twelve short puzzles that each have an obvious — and wrong — intuitive answer. Take a breath and check your arithmetic. Your score reflects how often you override that gut response with deliberate thought.
About the Cognitive Reflection Test
The cognitive reflection test was popularized in 2005 as a way to measure whether people pause to check an easy-looking answer. Every question plants a fast, intuitive answer that feels right, that a moment of reflection overturns.
Our 12 questions follow the same pattern but use different numbers and settings, so the test stays fair. You type a number for each question, and we track how many you get right, how often you give the intuitive trap answer, and your average time per question.
About
The Cognitive Reflection Test presents twelve short puzzles that each have an intuitive but incorrect answer. The test measures a person's tendency to override an immediate gut response and engage in deliberate, analytical thinking. By requiring the solver to pause and verify the first impulse, it reveals how automatically someone shifts from fast, heuristic processing to slower, logical reasoning.
Each item is framed as a simple word problem or arithmetic question that looks trivial at first glance. The deceptive ease of the surface answer tempts quick responding, while the correct solution demands a brief moment of self-checking. Performance on the set therefore reflects the habit of monitoring one's own thinking rather than raw intelligence or math knowledge alone.
How your result is scored
The result is the total number of puzzles answered correctly out of twelve. Each correct response indicates that the test-taker recognized the trap answer and applied a more careful reasoning step before finalizing the choice.
A higher count suggests a stronger disposition to question initial impressions and re-evaluate problems before concluding. A lower count simply shows a greater reliance on fast, intuitive responses in these specific items; it does not diagnose any cognitive deficit or predict broader intellectual ability.
Tips to improve
- Pause for a few seconds after reading each puzzle before writing an answer.
- Ask yourself what assumption the quick answer relies on and test that assumption.
- Re-read the wording carefully; the trick often hides in a single word or phrase.
- Practice similar riddles to train the habit of second-guessing intuitive jumps.
- Work in a quiet setting to reduce pressure to respond rapidly.

Frequently asked questions
- Is this the original three-question CRT by Frederick?
- No, this version expands the concept to twelve items while keeping the same principle of intuitive traps.
- Do I need math skills beyond basic arithmetic?
- Only elementary arithmetic is required; the difficulty lies in spotting the misleading intuition.
- Can my score change if I retake the test?
- Yes, familiarity with the trap patterns usually raises scores on repeat attempts.
- Does a low score mean I have poor reasoning ability?
- Not necessarily; it only shows a tendency to accept the first answer on these specific puzzles.
