Ideas of Eysenck and his supporters
According to the concept of Eysenck, the human creativity index is determined by the level of his intelligence. Hans Jürgen Eysenck, based on IQ's connection with Guildford's tests on divergent thinking, suggested that creativity is one of the components of overall mental development.

Supporters of Eysenck and his suggestion, in order not to be unfounded, conducted several practical studies, one of the most serious among which was the work of the American psychologist Lewis Madison Termen. In 1926, together with another , he conducted an analysis of the biographies of 282 famous people in order to evaluate their IQ based on their achievements at the age of 17 to 26 years. In their studies, scientists also relied on the Stanford-Binet scale, which allows them to assess their intelligence in their childhood.
