Taking an IQ test shouldn't look like a hole during the SAT (University Acceptance Test) marathon In fact, what has been hailed as the world's shortest IQ test in the world is three complete questions. Yes, you can take it now and start bragging with your friends within 30 minutes.
Deceptive question
The Cognitive Reflection Test (CRT) was developed by psychologist Shane Friedrich in 2005. In a paper published in The Economic Perspectives, Frederick describes that he picked the three questions because "they all give wrong impulsive responses". This means that questions make it easier for people to quickly jump to conclusions, rather than analyze seemingly simple test items.
This type of mental deception is how a few people can triumph each of the three questions. Beginning in January 2003, the CRT was administered to 3,428 respondents in 35 separate studies over a 26-month period. During that experience, only 17% of students from the best universities in the world (such as Yale and Harvard) earned an ideal score in CRT questions.
Based on the results of this 26-month experiment, Frederick introduced the full CRT test to the world in 2005. This short test is designed to test a person's ability to ignore the response of his intuitive intuition and think more rationally.
