Think you're smart?
Don't get too full of yourself before taking this IQ test. Despite the fact that it's only 3 questions long, over 80 percent of people who take the test fail to score 3 out of 3.
The test is the world's shortest IQ test and was created by MIT professor Shane Frederick. It was first introduced in 2005 and people have yet to do better.
Only 17 percent of takers answered all 3 questions correctly. Described as a Cognitive Reflection Test, the MIT professor describes it is easy to pass 3 out of 3. Figures for him, he made it!
The first question is "A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?"
You're probably thinking 10 cents is the correct answer...
Well, that'd be way too simple. You're actually wrong. The correct answer is not 10 cents, but you are not alone in answering incorrectly. 4 out of 5 people who take the test answer this very question wrong.
