Mainstream Science on Intelligence - 1994
Statement signed by 52 Academics in the WSJ
5 "Intelligence tests are not culturally biased"
8 "The bell curve for whites is centered roughly around IQ 100; the bell curve for American blacks roughly around 85; and those for different subgroups of Hispanics roughly midway between those for whites and blacks. The evidence is less definitive for exactly where above IQ 100 the bell curves for Jews and Asians are centered"
14 Heritability estimates range from 0.4 to 0.8 ... indicating genetics plays a bigger role than environment in creating IQ differences"
