The World’s Shortest IQ Test: Find Out How Smart You Are In Just 3 Steps

About 83% of people miss at least one of the questions on the “IQ Test.”

Do you think you can provide correct answers for the Cognitive Reflection Test (CRT)?

According to Wikipedia, the CRT is a task that measures individual’s tendency to interrupt a wrong intuitive response and try to find a correct answer.

Back in 2005, psychologist Shane Frederick was the first one who described it. This Cognitive Reflection Test has a balanced positive correlation with measures of intelligence, like the Intelligence Quotient test. Also, it correlates in a high way with many measures of judgment.

In one survey in which there were 3,428 people, surprisingly there were 33% of people who missed all three questions. About 83% of the people answered at least one question incorrectly. And, interestingly, even well-educated people provided wrong answers.

About 48% of MIT students managed to answer all of the questions correctly. In a study from 2003, only 17% of the participants provided correct answers to all questions. However, if you do not answer correctly all of the questions, do not beat yourself up.

There are just three questions between being of an average intelligence and a Brainiac. But, are the questions easy?

Since this test has only three questions, it has been called as the shortest IQ test. Every question assesses your abilities to identify a problem that may be harder than it seems.

Experts claim that providing the correct answers means the person is a genius, but remember that the time in which you get the solution, also matters. So, think quickly.

The Cognitive Reflection Test Questions

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?

  • The answer to the first question is 5 cents. You may have answered 10 cents, but the answer is a little less. When you have a ball that costs 5 cents, and a bat that costs 1.05 cents you get to $1.10. So, it is clear that 1$.05 is $1 more expensive than 5 cents.

According to a study from the University of Princeton, people who answered “10 cents” were less patient than              others who answered correctly.

  • The answer to the second question is 5 minutes. You may feel like you should say 100 minutes, but it would not take that long. Since 5 minutes are needed for one machine to produce one widget, a hundred machines would need 5 minutes to produce a hundred widgets.
  • The answer to the last question is 47 days. Even though because of your intuition, you may have answered 24 days, keep in mind that the area of the lily pads patch doubles each day. So, the lake needs just a day to go from half covered to fully. When you take a day from 48, you get 47.

So, did you answer correctly?
