While it might not seem like much to most the CRT is the world’s shortest IQ test and is one of the hardest. It consists of a mere three questions, three questions that hardly anyone can answer correctly.

This quiz came about back in 2005 and was created by psychologist Shane Frederick. He designed it to test a person’s ability to ignore their gut response. He wanted to make them slow down and give themselves a reality check.

While this might not sound all that hard, these three questions are some that only 17 percent of those who participated in his study were able to get right. While some people were able to answer one or two of them hardly anyone was able to answer all three. These questions generate an incorrect intuitive answer that many just cannot get over to reveal the correct answer, if you are able to question yourself you might be able to get them all right.

# The CRT Quiz Questions Are As Follows:

**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? ___ cents**

**2. If it takes 5 machines 5 minutes to make 5 widgets, how long would it take**

**100 machines to make 100 widgets? ___ minutes**

**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? ___ days**

Now, if you want to take some time to think these questions over feel free to do so. Below you will find the answer to each one. While these answers might not be what you’d expect they are very much correct.

# The Answers To The CRT Quiz:

## 1. 5 cents

While right off the bat you would think 10 cents would make the perfect answer it isn’t. The answer is actually around 5 cents because the bat would cost about $1.05 if it were to cost exactly one dollar more than the ball.

## 2. 5 minutes

Sure, you might want to think 100 minutes but that would be wrong. It takes 5 minutes for 1 widget machine to make 1 widget. This meaning it would take 5 minutes to make 100 from 100 machines and so forth. Crazy, right?

## 3. 47 days

No, not 27 days the answer is 47 days. While it might not seem right, it is. Take just one day away from 48 and you have 47 since the area of the lake being covered doubles each day. Don’t feel bad, I didn’t get it right my first time either.

Isn’t this whole concept of false intuition fascinating? What do you think about all of this? I for one am quite mad that I didn’t pass, how did you score?
