Ape (especially chimpanzee) social intelligence, the authors say, has been routinely mismeasured because apes are tested in comprehensively different circumstances from the children with whom they are compared - and against whose performance theirs is found to be lacking. Hopkins of Georgia State University have framed their new Animal Cognition article, " The mismeasure of ape social cognition," around Gould's book. Bard of the University of Portsmouth, and William D. Leavens of the University of Sussex, Kim A. The Mismeasure of Man ignited ferocious discussion (and the occasional subsequent correction) that has continued even in recent years across biology, anthropology, psychology and philosophy: Its argument mattered not only for how we do science, but how science entangles with issues of social justice. Different environmental histories across human groups, in fact, affect testing outcomes in significant ways: There is no innate superiority due to genes. In 1981, the evolutionary biologist Stephen Jay Gould's book The Mismeasure of Man hit the presses.Ī take-down of studies purporting to demonstrate that the intelligence of humans is genetically determined - and that some human groups (read "white Western Europeans") are innately superior - the book exposed interpretive bias and scientific racism in the measurement of human intelligence. ![]()
