Get it together, now you have to pass the world's shortest intelligence assessment test! It is called Cognitive Reflection Test (CRT), that is, a test of cognitive reflection. It was invented by Yale University professor Shane Frederick to assess how a person is able to perceive complex, which at first glance seems simple.

So let's go!

Question 1

A baseball bat and ball cost $1.10 together. The bat costs $1 more than the ball. How much is the ball worth?

Question 2

5 machines produce 5 things in 5 minutes. How long does it take 100 machines to produce 100 gizmos?

Question 3

The pond is overgrown with water lilies. Every day their area doubles. The entire lake will be overgrown in 48 days. How many days will the flowers absorb half of its surface?

And now the correct answers

Answer 1

How much did you get - 10 cents? Like most hurry-ups who think they're too smart for that simple question. Judge for yourself: if the ball really cost 10 cents, and the bat cost a dollar more, then it alone would cost ten dollars, and this is the total cost of the items. In fact, the price of the ball is 5 cents.

Answer 2

Did you succumb to the temptation and automatically answer “100”? In vain, the question was a trick. In fact, it takes a hundred machines to produce a hundred things the same amount of time as it takes five units to create five things. That is 5 minutes. From a change in the number of machines, the time for making gizmos does not change!

Answer 3

Oh, how many of them - those who answered "24 days" - have sunk into oblivion! You too? Do not be sad, this question is the pinnacle of the test. Let's think logically: if every day the area of ​​\u200b\u200bthickets doubles, then they will occupy half the surface of the pond a day before the expiration of the 48-day period required by the flowers in order to completely cover the reservoir. That is 47 days.

We have tested 3 151 654 human!

Intelligence quotient (eng. IQ - intelligence quotient) - a quantitative assessment of the level of intelligence of a person: the level of intelligence relative to the level of intelligence of an average person of the same age. It is determined using special tests. IQ tests are designed to assess mental abilities, not the level of knowledge (erudition). The IQ is an attempt to measure the general intelligence factor (Wikipedia).

The IQ test lasts 30 minutes and contains 40 simple questions!

When performing the test, you can not use paper, a calculator, a pen, a cheat sheet, the Internet and friend's tips :) IQ tests are designed so that the results are described by a normal distribution with an average IQ of 100 and such a spread that 50% of people have an IQ between 90 and 110 and 25% each below 90 and above 110. Average IQ of graduates American universities is 115, excellent students - 135-140. An IQ value of less than 70 often qualifies as mentally retarded.
