This Is The Shortest IQ Test And It Is Just Three Questions! Can You Answer Correctly?

The Cognitive Reflection Test (CRT) is considered to be the shortest IQ test ever. Apparently, you'll only need to answer three questions, and the test will tell you whether you're a genius or not.


The quiz, created in Princeton in 2005 by psychologist Shane Frederick, will test your ability to ignore your gut response and give well-thought, logical answers. Or in psychology terms, are you able to ignore system 1 (intuition) and think in favor of system 2 (analytic) thinking? To succeed in the test, you need to spend time reflecting on your answer and always question your intuitive response.


Of course, if you want to be proven a genius, you should get all three questions correct, but your speed also matters. Speedier but well-thought answers is another sign of a higher IQ.


So, how intelligent are you? Remember, the questions may not be quite as simple as they'' first seem. Even students of the top universities in the world (including Yale and Harvard) failed to answer all three answers correct in a 2003 study. Actually, only 17% achieved a perfect score.


Take the quiz below:


1. A bat and a ball cost $1.10 in total. If the bat costs $1 more than the ball, then how much does the ball cost?


2. If 5 machines need 5 minutes to make 5 widgets, then how long would 100 machines need to make 100 widgets?


3. In a lake, there is one patch of lily pads. The patch doubles in size every day. If it takes 48 days for the patch to cover the entire lake, then how long would it take for the patch to cover half of the lake?

The Answers


1. 5 cents – Most people would answer 10 cents. The answer is a little less – a 5 cent ball plus a bat that costs $1.05 will set you back $1.10. Sure enough, $1.05 is exactly $1 more expensive than 5 cents. (A Princeton study discovered that those who responded 10 cents were "significantly" less patient than the people who got the right answer.)


2. 5 minutes – Your gut instinct may be to say 100 minutes. Luckily, it wouldn't take quite so long. From the question, one can determine it takes exactly 5 minutes for one widget machine to make one widget. Therefore, it'd take 5 minutes to make a hundred widgets from a hundred widget machines.


3. 47 days – You may have guessed 24 days. It might seem intuitive to half the number of days as you're trying to think about half the size of the lilypad patch. However, if the area of the lake covered in lilypads doubles every day, it'd only take 1 day for it to go from being half covered to being fully covered. Take one day away from 48 days and what's left is 47.
