"The Bell Curve (Herrnstein & Murray, 1994) presented general readers an update of the evidence for the hereditarian position along with several policy
recommendations and an original analysis of 11,878 youths (including 3,022 Blacks) from the 12-year National Longitudinal Survey of Youth. It found that
most 17-year-olds with high scores on the Armed Forces Qualification Test,regardless of ethnic background, went on to occupational success by their late 20s
and early 30s, whereas those with low scores were more inclined to welfare dependency. The study also found that the average IQ for African Americans was
lower than those for Latino, White, Asian, and Jewish Americans (85, 89, 103,106, and 113, respectively; Herrnstein & Murray, 1994, pp. 273–278).
Currently, the 1.1 standard deviation difference in average IQ between Blacks and Whites in the United States is not in itself a matter of empirical dispute. A
meta-analytic review by Roth, Bevier, Bobko, Switzer, and Tyler (2001) showed it also holds for college and university application tests such as the Scholastic
Aptitude Test (SAT; N
2.4 million) and the Graduate Record Examination (GRE; N
2.3 million), as well as for tests for job applicants in corporate settings
(N
0.5 million) and in the military (N
0.4 million). Because test scores are the best predictor of economic success in Western society (Schmidt & Hunter,1998), these group differences have important societal outcomes (R. A. Gordon,1997; Gottfredson, 1997)."
