The Smart Culture

Book excerpt: Interweaving engaging narratives with dramatic case studies, Robert L. Hayman, Jr., has written a history of intelligence that will forever change the way we think about who is smart and who is not. To give weight to his assertion that intelligence is not simply an inherent characteristic but rather reflects the interests and predispositions of those doing the measuring, Hayman traces numerous campaigns to classify human intelligence. His tour takes us through the early craniometric movement, eugenics, the development of the IQ, Spearman's "general" intelligence, and more recent works claiming a genetic basis for intelligence differences.
