You may have dark moods, or you may have tried to get your driving license. Both are signs of intelligence, according to studies. But are you really as smart as you think you are? The Cognitive Reflection Test (CRT) is the world's shortest intelligence test with only three questions and can determine whether you are a genius or not.
It was developed in 2005 by Princeton psychologist Shane Frederick and assesses your ability to process information received slowly and rationally. To do well, you need to take the time to answer the questions and do not jump to conclusions quickly.
Keep in mind that the answers are not as simple as they seem. A 2003 study found that students at the most prestigious US universities failed to find the right answer to all three questions. Only 17% found all three correctly.
