Cognitive Reflection Test Practice Test : Free Exam Questions & Study Guide
The cognitive reflection test (CRT) is often called the world's shortest IQ test, designed to measure a person's ability to override an intuitive "gut" response and engage in deeper analytical thinking. Originally developed by Shane Frederick in 2005, this simple yet deceptive assessment challenges your cognitive processing skills.
Whether you are preparing for a job assessment or simply want to test your mental sharpness, our cognitive reflection test questions provide the perfect practice ground. Understanding the mechanics behind the cognitive reflection test can significantly improve your problem-solving abilities and help you avoid common intuitive traps.
The Cognitive Reflection Test is unique because its questions are designed to trigger an immediate, incorrect intuitive answer. Success requires suppressing this "System 1" impulse and activating "System 2" analytical reasoning.

To pass the cognitive reflection test crt, you must understand the difference between intuitive and analytical thinking. This study guide breaks down the core components of the frederick cognitive reflection test.
Cognitive Reflection Test Format
The structure of the cognitive reflection test is deceptively simple. Unlike lengthy exams, the CRT focuses on a few potent questions that effectively separate intuitive thinkers from analytical thinkers.
The "Bat and Ball" problem tests your ability to handle simple linear equations without falling for surface-level number association.
- Topics: Cost difference, variable isolation
- Questions: 1 key question
The "Widgets" problem assesses your understanding of independent rates versus collective output time.
- Topics: Production rates, time management
- Questions: 1 key question
The "Lily Pad" problem tests your grasp of geometric progression and backward reasoning in growth scenarios.
- Topics: Geometric series, backward induction
- Questions: 1 key question
The test is designed to trigger System 1 (fast, intuitive) thinking, which provides the incorrect "lure" answers.
- Topics: Cognitive bias, heuristic error
- Questions: Applied to all items
Success requires activating System 2 (slow, analytical) thinking to verify and correct the initial impulse.
- Topics: Critical thinking, error correction
- Questions: Required for correct answers
Newer versions like the extended cognitive reflection test add non-math verbal questions to test semantic inhibition.
- Topics: Linguistic traps, belief bias
- Questions: 4-7 additional items
The single most effective strategy for the CRT is to distrust your first answer. If an answer comes to you instantly without any calculation, it is almost certainly the "lure" answer designed to trick you.
