Peer reviewedRushton, J. Philippe; And Others – Intelligence, 1991
Calculation of cranial capacities for the means from 4 Mongoloid and 20 Caucasoid samples (raw data from 57,378 individuals in 1978) found larger brain size for Mongoloids, a finding discussed in evolutionary terms. The conclusion is disputed by L. Willerman but supported by J. P. Rushton. (SLD)

Peer reviewedLevin, Michael; And Others – Intelligence, 1994
Michael Levin argues that data from the study are consistent with a black/white IQ difference that is significantly genetic. Richard Lynn maintains that adoption by middle-class, white families has no effect on intelligence. Waldman, Weinberg, and Scarr respond to these criticisms and support the original conclusions.
