Secrets of the Creative Brain
But despite the implications of the title Genetic Studies of Genius, the Termites’ high IQs did not predict high levels of creative achievement later in life. Only a few made significant creative contributions to society; none appear to have demonstrated extremely high creativity levels of the sort recognized by major awards, such as the Nobel Prize. (Interestingly, William Shockley, who was a 12-year-old Palo Alto resident in 1922, somehow failed to make the cut for the study, even though he would go on to share a Nobel Prize in physics for the invention of the transistor.) Thirty percent of the men and 33 percent of the women did not even graduate from college. A surprising number of subjects pursued humble occupations, such as semiskilled trades or clerical positions. As the study evolved over the years, the term gifted was substituted for genius. Although many people continue to equate intelligence with genius, a crucial conclusion from Terman’s study is that having a high IQ is not equivalent to being highly creative. Subsequent studies by other researchers have reinforced Terman’s conclusions, leading to what’s known as the threshold theory, which holds that above a certain level, intelligence doesn’t have much effect on creativity: most creative people are pretty smart, but they don’t have to be that smart, at least as measured by conventional intelligence tests. An IQ of 120, indicating that someone is very smart but not exceptionally so, is generally considered sufficient for creative genius.
