Cognitive Reflection Test

Updated: Feb 18, 2025

The Cognitive Reflection Test (CRT) is a unique assessment designed to measure a specific cognitive ability, the ability to reflect on a question and resist the temptation to provide the first, intuitive response that comes to mind. Unlike traditional IQ tests, the CRT focuses on cognitive reflection, which involves deliberate and logical thinking.

Cognitive Reflection Test Instructions

Read each question carefully, pay close attention to the details of each question and resist the urge to answer instinctively.

Take time to analyze the problem logically. While the CRT is brief  with 3 questions, focusing on accuracy rather than speed is crucial for accurate results. Ready to test your cognitive reflection skills? Take the test below and see how you perform!

About Critical Race Theory Test

A CRT (Critical Race Theory) test online typically refers to assessments or quizzes designed to evaluate a person's understanding of Critical Race Theory, its concepts, and its implications in various fields, such as education, law, and social justice.

These tests might cover topics like:

  • The history and development of Critical Race Theory
  • Key concepts, such as systemic racism, intersectionality, and the social construction of race
  • The impact of race and racism on societal structures and individual experiences
  • Critiques and debates surrounding Critical Race Theory

Features off the CRT test

The Cognitive Reflection Test (CRT) is widely regarded as one of the most reliable and scientifically validated cognitive assessments. Here are some key points about its validity:

  • Short and Effective: The CRT is the world’s shortest scientifically validated test, requiring only a few minutes to complete while maintaining high predictive validity.
  • Predictive Power: Despite its brevity, the CRT’s predictive accuracy rivals or exceeds other cognitive tests, making it a valuable tool in psychological and decision-making research.
  • Exposure Effect: Familiarity with the CRT questions can improve performance, as 44–51% of test-takers have encountered the original questions before. To address this, revised versions such as the CRT-Long, CRT-7, and CRT-2 have been developed, featuring new questions to ensure fairness and accuracy.

How Does the CRT Test Relate to Your IQ?

While the Cognitive Reflection Test (CRT) is not specifically designed as an intelligence test, it does have a moderate correlation with IQ scores. Here’s how the CRT connects to your IQ and cognitive abilities:

  • Reflection vs. Impulsiveness: The CRT measures your ability to suppress impulsive, intuitive answers and engage in reflective thinking. This cognitive skill overlaps with certain aspects of IQ, particularly in problem-solving and logical reasoning. A high CRT score often indicates strong analytical thinking, a trait commonly associated with higher IQ levels.
  • Executive Function and Response Inhibition: The CRT assesses response inhibition, one of the key executive functions. This ability to pause and critically evaluate a situation before responding is also integral to many tasks on IQ tests, such as pattern recognition and logical problem-solving.
  • Predictive of Decision-Making Ability: CRT scores are strongly correlated with decision-making abilities, such as those explored in expected utility theory and prospect theory. Since IQ tests also measure reasoning skills and decision-making, CRT performance can provide insight into your cognitive processes in these areas.
  • Numerical and Verbal Reasoning: While CRT employs cognitive reflection primarily, reasoning and basic Math literacy tie it with sub paradigms of IQ, such as math and word.

When taking the Cognitive Reflection Test (CRT), you have the opportunity to assess how reflective you are and how easily you can avoid impulsive decisions. This is your chance to discover how logical your thinking process is. Take the test today and see how good a thinker you are before jumping to conclusions!
