Beraldo, Sergio – Intelligence, 2010

Peer reviewedWolff, JosePh L. – Intelligence, 1979
Explanations of differences in IQs of Northern and Southern Blacks focus on selective migration (hereditarians) or environmental causes such as education, discrimination and cultural deprivation. In this paper the environmentalist position is questioned and certain neglected features of Lee's data are construed as providing strong evidence for…
