Group Differences in IQ (Intro Psych Tutorial #121)

www.psychexamreview.com In this video I consider group differences in IQ scores and the history of how group differences by race and nationality have been interpreted. This includes discussion of the eugenics movement, social Darwinism, the Army Alpha and Army Beta tests created by Robert M. Yerkes, Henry Goddard, and Lewis Terman, and problems of bias and standardization in early tests. Finally I consider the implications of these results for social policies including immigration laws and "artificial selection" via forced sterilization.
