The notion that intelligence is somehow related to race is a notoriously tenacious issue in America. Anthropologist Alexander Alland provides the most comprehensive overview of the recent history of research on race and IQ, offering critiques of the biological determinism of Carlton Coon, Arthur Jensen, Cyril Burt, Robert Ardrey, Konrad Lorenz, William Shockley, Michael Levin, and others. This reasoned, authoritative history also explains the basis of evolutionary genetics for the general reader, concluding that biologically, race cannot explain human variation. Written in a lively, conversational style, Alland imparts real, substantive scientific arguments, cuts through the ideological posturing and jargon that so often characterizes discussions about race, and shows us a more nuanced and scientifically valid way to understand the diversity that is the human condition.
