The CRT was introduced by Shane Frederick in a 2005 paper and is now one of the most cited papers in behavioral economics. CRT performance predicts willingness to accept uncertainty, financial literacy, and resistance to cognitive biases. It is a measure of "thinking disposition," not raw intelligence.
What does the Cognitive Reflection Test test measure?
The Cognitive Reflection Test (CRT) presents problems with intuitive but incorrect answers. The classic example: "A bat and ball cost $1.10. The bat costs $1 more than the ball. How much does the ball cost?" Most say 10¢ (wrong); the answer is 5¢. It measures the tendency to override System 1 (fast, intuitive) thinking with System 2 (slow, deliberate) reasoning.
How to improve your Cognitive Reflection Test score
- → For each question, actively ask: "What is my first instinct telling me - and why might it be wrong?"
- → Work the math explicitly. The bat-and-ball problem requires algebra, not intuition.
- → CRT score correlates with financial decision quality, patience, and scientific thinking - it's worth training.
