Here is what you would never know about the Minnesota study from reading Jensen and Rushton, or, for that matter, Saletan. It held neither race nor expected IQ constant; the black children were adopted at a later age than the other children, which the study’s own authors note is associated with depressed IQ; the black children’s mothers had lower educational levels than those of the white children; the “quality of placement” for the white children was higher than for the other children; and as the study’s own authors have noted, the black and mixed-race children experienced severe adjustment problems as they grew up. -- http://www.slate.com/id/2179073 http://www.slate.com/id/2179073
