ABSTRACT

It is in the United States that racial and ethnic differences in intelligence have been most extensively researched. There is a considerable literature on these differences, much of which is given in Loehlin, Lindzey and Spuhler (1975), Vernon (1979, 1982), Jensen (1980) and Flynn (1980). The groups which obtain low mean IQs are the Blacks, the American Indians and the Hispanics. The groups which obtain high IQs are the Whites, the Jews and the Orientals.
