Take the world’s shortest IQ test to figure out where you fall in the intelligence spectrum. Have you always wondered about your IQ and where it falls on the intelligence spectrum?

If you want to know your IQ but don’t want to spend a lot of time answering a million questions, then this test is tailor-made for you. The world’s shortest IQ test is called the Cognitive Reflection Test (CRT) and has only 3 questions.

CRT was developed in 2005 by Shane Frederick from Princeton and was published in the Journal of Economic Perspectives. This IQ test aims to fulfill the following criteria:

  • The test attempts to find out how you think: do you trust your gut feelings or do you take time to think rationally?
  • CRT identifies how good you are in intuitive thinking and analytical thinking.
  • However, getting all three answers correct is not the only parameter of having a higher IQ. Your speed of answering determines this too.

Before proceeding to the world’s shortest IQ test, just be a bit careful, and don’t rush into answering the questions. Think clearly and use your common sense before zeroing in on your final answers.
