Racial Versus Socioeconomic Groups Within the U.S.

More than 40 years ago, Davis and Dollard (1937) contrasted the social systems of caste and class. Among castes there is no individual mobility; one is born into a caste and stays there regardless of individual merit. Races are castes in the U.S. Social classes exist within castes, and individuals can move up or down the class structure according to criteria of individual merit. Dobzhansky (1962) spelled out the implications of this differentiation for genetics: Genetic differences are less likely to arise between castes because all of the genetic individual variability is kept within them—there are few ways out of one racial group into another. By contrast, there are permeable boundaries among social class groups, not perfect mobility according to individual merit, but sane 30 to 40% changes of status in each generation. The individuals who move socially take their genes with than, mate, and reproduce in their achieved status. Thus, there is a far higher probability of social class than racial group differences in those characteristics that contribute to individual mobility (Scarr-Salapatek, 1971a, 1971b).

The implication of the differences between race and social class for intellectual achievement is that there are more likely to be genetic differences in IQ scores between social class than racial groups. Let us review the recent research on this issue.
