To prove that you are truly a genius you must get all three questions correct but speed also matters. The quicker you are able to correctly answer the questions the higher your IQ is.
The Cognitive Reflection Test (CRT) has been crowned as the world’s shortest IQ test. Apparently, it only takes three questions to know if you are any Einstein or a Homer Simpsons of this world. The quiz was developed in Princeton in 2005 by psychologist Shane Frederick. It is designed to test your ability to ignore your gut response and think slower and more rationally. To succeed in this test, you must spend time reflecting on your answer and question your intuitive response.
Remember the questions might not be quite simple as they first seem. In 2005 study students at the world’s top universities, including Harvard and Yale, failed to get all three answers correct. In fact, only 17 percent achieved a perfect score.
Before you start the quiz ensure you put your timer on to measure how long it takes you to answer all three questions. Try it with your friends and family to see who is the fastest and has the highest IQ among you all. I will put the answers right after the test so you can check to see how smart you are. Enjoy!
1. A bat and a ball cost $1.10 in total. The baa costs $1 more than the ball. How much does the ball cost?
2. If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?
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?
Write your answers in the comment section below.
1. 5 cents
Most people would have guessed 10 cents. The bat costing $1.05 plus a 5 cents ball will amount to exactly $1.10. (The study found that people who responded 10 cents were significantly less patient that those who got the right answer)
2. 5 minutes
From the question, we can determine it takes exactly 5 minutes for one widget machine to make one widget; therefore it would take 5 minutes to make 100 widgets from 100 widget machines.
3. 47 days
It seems correct to half the number of days because you are halving the size of the lily pad patch, but if the area of the lake covered in lily pads doubles everyday, it will only take one day for it to go from being half covered to fully covered.
How many did you get correct?
