Question

Quizplus · Accepted Answer

Herrnstein and Murray argue in The Bell Curve that heredity plays a considerable role in individual and social class differences in IQ. They claim that IQ is largely inherited and that genetics account for approximately 60% of IQ differences among individuals. They also assert that the relatively stable IQ differences across ethnic groups are, in part, due to genetic differences in intelligence.
