Is IQ so controversial?
"IQ tests only tell you how good you are at doing IQ tests". This refrain is heard whenever people bring up the idea of cognitive testing, but it turns out that it is completely contrary to the evidence. Intelligence tests in fact tell us a lot about educational and occupational success, and recent work in the field of ‘cognitive epidemiology’ has informed us about how cognitive abilities can even predict health. In this talk, Dr. Stuart Ritchie (The University of Edinburgh) discusses the psychological, neuroscientific, and genetic data on intelligence testing, separates fact from fiction, and, explores the many reasons—political, sociological, and otherwise—that the controversy surrounding IQ testing has obscured solid science.
Stuart J. Ritchie is a Postdoctoral Fellow at the Centre for Cognitive Ageing and Cognitive Epidemiology at the University of Edinburgh. His research is on intelligence differences—both between people and across the life span—and what might explain them. He has published papers in many peer-reviewed scientific journals on the psychological, neural, genetic, and social aspects of human cognitive ability.
