Heredity, environment, and race differences in IQ: A commentary on Rushton and Jensen (2005).

J. P. Rushton and A. R. Jensen (see record 2005-03637-001) ignore or misinterpret most of the evidence of greatest relevance to the question of heritability of the Black-White IQ gap. A dispassionate reading of the evidence on the association of IQ with degree of European ancestry for members of Black populations, convergence of Black and White IQ in recent years, alterability of Black IQ by intervention programs, and adoption studies lend no support to a hereditarian interpretation of the Black-White IQ gap. On the contrary, the evidence most relevant to the question indicates that the genetic contribution to the Black-White IQ gap is nil. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
