The intelligence test of only three questions that few manage to overcome

We all love to boast of our skills, knowledge and intelligence. And nothing better than trying quickly, with only three questions and on a website. The risk? Although the test seems easy, few succeed.

Professor Shane Frederick of MIT, Mbadachusetts Institute of Technology, has developed this test of intelligence considered the shortest in the world. From his study More than 3000 people participated, from different areas and with different levels of education. Some were students from prestigious universities, such as Harvard or Princeton.

Despite the qualifications, only 17% of the participants achieved the ideal score. 3 out of 3. These are the three questions of the test, based on mathematical operations that test cognitive skills.

– A bat and a ball cost $ 1.10 in total. The bat costs 1 dollar more than the ball. How much does the ball cost?

– If 5 machines take 5 minutes to make 5 devices, how long would it take 100 machines to make 100?

– In a lake, there is a segment of lily leaves. Every day, the segment doubles its size. If the segment takes 48 days to cover the entire lake, how long will it take for the segment to cover half of the lake?

If you answered all three questions thinking about 10 cents, 100 minutes and 24 days, respectively, congratulations: they are part of the majority … but the answers are incorrect.

The researchers found significant differences between responses by bad. They found that in the case of women, the scores were related to temporal preferences. In the case of men, they were related to risk preferences.

"In general terms, being smart makes women patient and requires men to take more risks," said the study's author on the basis of this badysis.

The right answers? 5 cents, 5 minutes and 47 days.
