What Is the Cognitive Reflection Test (CRT)?
The Cognitive Reflection Test, also known as the CRT, was designed to measure an individual's cognitive reflective ability of individuals. It is designed to identify how well a person is able to suppress an intuitive response, which often leads to a wrong answer, and provide a correct answer by using analytical skills.
In other words, it assesses whether a person is able to identify their initial, instinctive answer that might be incorrect and then apply more deliberate and analytical thinking to arrive at the correct solution.
CRT consists of just three questions.
Despite its brevity, the CRT is challenging and requires logical thinking. It measures cognitive reflection — the ability to suppress an intuitive but incorrect answer in favor of a more reflective and correct one.
This quick, free IQ test is popular among researchers and educators for its effectiveness and simplicity, making it an excellent tool for exploring the intricacies of human thought and decision-making.

Remember, the goal is to think deeply and avoid jumping to the first answer that comes to mind. Take your time to reflect on each question carefully and consider the possibility that the most obvious answer might not be correct.
The Cognitive Reflection (CRT) 3-Question IQ Test
Question 1. A bat and a ball cost $1.10 in total. The bat costs $1.00 more than the ball. How much does the ball cost?
Question 2. If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?
Question 3. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

Understanding the CRT Questions and Answers
Each question in the CRT is designed to be a "cognitive tripwire." The initial response seems obvious and is often quickly produced, but it is incorrect.
To answer correctly, individuals must engage in cognitive reflection. This process involves rethinking the problem, suppressing the intuitive response, and finding an accurate solution.
Before we get to the answers, we think you should know that, according to test creator Shane Frederick, only 17% of the population pass the test, getting all three questions correct!
CRT Question #1: The Bat and Ball Problem
This question tests your ability to perform basic algebra and resist the immediate but incorrect answer.
- Correct Answer (5 cents): Approximately 20% of people answer correctly.
- Incorrect Answer (10 cents): Approximately 80% of people answer incorrectly.
The intuitive answer is $0.10 because it quickly satisfies the condition of the total cost.
However, upon reflection, you realize that if the ball costs $0.10, the bat would cost $1.10, totaling $1.20. Therefore, the correct calculation shows the ball costs $0.05 and the bat costs $1.05.
CRT Question #2: The Widget Problem
This question tests your understanding of rates and scalability.
- Correct Answer (5 minutes): Approximately 30% of people answer correctly.
- Incorrect Answer (100 minutes): Approximately 70% of people answer incorrectly.
The intuitive answer of 100 minutes is incorrect because it fails to consider the rate at which the machines produce widgets.
If 5 machines make 5 widgets in 5 minutes, each machine makes 1 widget in 5 minutes. Therefore, 100 machines would still take 5 minutes to make 100 widgets.
CRT Question #3: The Lily Pad Problem
This question tests your understanding of exponential growth.
- Correct Answer (47 days): Approximately 20% of people answer correctly.
- Incorrect Answer (24 days): Approximately 80% of people answer incorrectly.
The intuitive answer is 24 days, as it seems logical to halve the total time.
However, since the patch doubles in size each day, the lake is half-covered one day before it is fully covered, making the correct answer 47 days.
How Many Did You Answer Correctly? Interpreting CRT Scores and the Connection to IQ Scores
While the CRT is not a comprehensive measure of intelligence, nor does it assess the many different types of intelligence, it provides valuable insights into one's cognitive reflection abilities.
For example, research indicates ADHD symptoms of inattention, hyperactivity, and impulsivity negatively affect CRT performance, with inattention being the most significant predictor. This finding highlights the critical role of working memory in reasoning ability, supporting the executive function model of ADHD.
That said, let's explore what your CRT score reveals about your cognitive reflection skills and how it correlates with IQ.
0 Correct Answers
Not getting any questions correct indicates a strong tendency to rely on intuitive responses without engaging in the deeper reflective thinking required to arrive at the correct answers.
This CRT score suggests lower levels of cognitive reflection, which can correlate with below-average IQ scores. It indicates a need for improvement in critical thinking and problem-solving skills. People who do not get any questions correct may benefit from practicing more reflective thinking strategies.
1 Correct Answer
Only one correct answer is most common for individuals with average IQ scores, showing some ability to engage in reflective thinking. It indicates that you have some ability to engage in reflective thinking and suppress your initial intuitive response.
A CRT score of 1 suggests a moderate level of cognitive reflection, but it is not a strong indicator of high IQ on its own. It may show that you have the potential to improve your reflective thinking skills.
2 Correct Answers
Getting two questions correct shows a higher level of cognitive reflection and an ability to question intuitive answers more effectively. This score indicates a good level of cognitive reflection, which correlates with higher IQ scores.
People who get two questions correct are often better at critical thinking and decision-making.
3 Correct Answers
Getting all three questions correct is rare and demonstrates a strong ability to engage in reflective thinking and to consistently overcome intuitive but incorrect answers.
A significant correlation exists between getting all three questions correct and having a high IQ. This indicates a high level of cognitive ability, critical thinking, and problem-solving skills. People who achieve this will likely perform well on traditional IQ tests and exhibit strong cognitive reflection.
CRT and IQ Testing: Role of Cognitive Reflection in Intelligence Tests
The Cognitive Reflection Test shares some similarities with traditional IQ tests but also has distinct differences.
While IQ tests measure a broad range of cognitive abilities, including logical reasoning, spatial ability, and verbal skills, the CRT focuses specifically on cognitive reflection. This makes the CRT a valuable complement to traditional IQ tests, providing a more nuanced understanding of an individual's cognitive abilities.
Performance on the CRT has been found to correlate with IQ scores, suggesting that individuals with higher IQs are generally better at reflective thinking. However, the CRT also reveals that even people with high IQs can fall prey to intuitive but incorrect answers if they do not engage in reflective thinking.
Many IQ tests include questions requiring you to think critically and reflectively. Understanding how cognitive reflection contributes to problem-solving and decision-making provides a more comprehensive picture of one's mental abilities and highlights areas for potential improvement.
