Can you correctly answer the Cognitive Reflection Test? (83 percent of people miss at least 1 question of this “IQ Test”)
The Cognitive Reflection Test (CRT) is a task designed to measure a person’s tendency to override an incorrect “gut” response and engage in further reflection to find a correct answer. It was first described in 2005 by psychologist Shane Frederick.
The CRT has a moderate positive correlation with measures of intelligence, such as the Intelligence Quotient test, and it correlates highly with various measures of judgment.
In a survey of 3,428 people, an astonishing 33 percent missed all three questions. Most people–83 percent–missed at least one of the questions.
Even very educated people made mistakes. Only 48 percent of MIT students sampled were able to answer all the questions correctly.
In a 2003 study, only 17 percent achieved a perfect score. If you don’t get all the answers right, don’t be too hard on yourself.
Three questions separate you from being of average intelligence and full-blown brainiac— but are they as easy as they seem?
This test has been hailed as the world’s shortest IQ test as it features just three questions.
Each one is designed to assess your abilities to identify a simple problem that might actually be harder than it first appears.

Not only do experts claim that getting the right answer is a sign of genius, but also the time frame in which you come up with your solution. So think fast!
The Quiz
1. A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?
2. If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?
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?
Once you have your answers, scroll down to see if you got them right!
The Answers
1. 5 cents – There’s a very good chance you guessed 10 cents.
The answer is actually a little less – a 5 cent ball plus a bat costing $1.05 will set you back $1.10. And, of course, $1.05 is exactly $1 more expensive than 5 cents.
(A Princeton study found that people who responded 10 cents were “significantly” less patient than those who got the right answer.)
2. 5 minutes – Your gut instinct might be to say 100 minutes. Fortunately, it wouldn’t take quite so long. From the question, we can determine it takes exactly 5 minutes for 1 widget machine to make 1 widget. Therefore, it would take 5 minutes to make 100 widgets from 100 widget machines.
3. 47 days – You might have guessed 24 days. It seems intuitive to half the number of days because you’re halving the size of the lilypad patch.
But if the area of the lake covered in lilypads doubles every day, it would only take one day for it to go from being half covered to fully covered.
Take one day away from 48 days and you’re left with 47.
