A surrounding web of assertions often accompanies this seemingly objective information. As stated sharply in the bestselling book The Bell Curve (Herrnstein and Murray, 1994), individuals are thought to be born with a certain intellectual potential; it is difficult to change that potential; and psychometricians can tell us from an early age how smart we are. Authors Richard Herrnstein and Charles Murray went on to trace various social ills to those with low intelligence levels and to hint that IQ scores may be related to race. The latter claims led to the sales and the furor surrounding the book.
