The CRT test was developed in 2005 by Yale University (USA) professor Shane Frederick, who at the time was working at the Massachusetts Institute of Technology.
The test is designed to assess a person’s tendency to ignore an incorrect intuitive answer and engage in further thinking in search of the correct answer.
It’s worth saying that even if you give the wrong answer, you shouldn’t feel bad about it. Scientists believe that this test has the ability to show an average level of intelligence, but does not necessarily reflect it.

Questions:
A baseball bat and ball cost a total of $1.10. The bat costs $1 more than the ball. How much does a ball cost?
If 5 machines take 5 minutes to produce 5 units, how long will it take 100 machines to produce 100 units?
There is an area in the lake where lilies grow. The area doubles every day. If it takes 48 days for the lilies to cover the entire lake, how long will it take for the patch to cover half the lake?
At first glance, these questions may seem incredibly simple, but there is something important to remember – Sh. Frederik designed them specifically to test how well you can ignore your intuition – in other words, the first answer that pops into your head – and instead apply more in-depth analytical thinking.
Test answers:
5 cents. Did you answer 10 cents? This is the answer that your intuition may have given you. A 5 cent ball and a $1.05 bat are actually $1.10. Sh. According to Frederick’s study, of nearly 3,500 people who took the test, those who answered 10 cents were “significantly less patient” than those who answered correctly.
5 minutes. The intuitive answer would be to continue the pattern of 100 minutes in which 100 machines produce 100 devices. However, a closer look reveals that each individual machine takes 5 minutes to produce one device. Increasing this number to 100 machines still takes only 5 minutes each to master a single device.
47 days. The most likely, but incorrect, intuitive answer to this question is 24 days. Intuitively, one wants to reduce the number of days by a factor of 2, but if the lily pad doubles in size every day, that means it was halved just a day before the 48th day, so the correct answer is 47 days.
