“The Terman results are deeply distressing. Let's not forget how highly gifted the C group was. If you had met them at five or six years of age, you would have been overwhelmed by their curiosity and mental agility and sparkle. They were true outliers. The plain truth of the Terman study, however, is that in the end almost none of the genius children from the lowest social and economic class ended up making a name for themselves.”
