Therefore, do not believe the Internet, which call the IQ level of Pythagoras, Napoleon and other people who died long before the introduction of the concept of intelligence quotient. In fact, the results of all these tests are quite controversial and you can talk about what mental age is and what it depends on for a long time.

    And measuring the theoretical coefficient is something irrational. You can measure weight, distance, even time (although you can also argue here). So, if we are going to answer this question, then the answer completely fits in the first sentence.
