ABSTRACT
The most powerful attempt to topple the second pillar of Jensenism was the notorious Burt Affair. The late Sir Cyril Burt, a founder of the hereditarian London School of psychology, had published a number of studies showing that the correlation in IQ for identical twins reared apart was 0.77. Arthur R. Jensen, in his 1969 Harvard Educational Review article, cited this figure and other similar findings by Burt on the inheritance of mental ability. The American Psychological Association itself has published an introduction to the genetics of individual differences, Nature, Nurture, and Psychology, edited by Robert Plomin and Gerald McClearn, which also agrees with that consensus. MieleAnd is that consensus reflected in psychology textbooks. There are a few exceptions, but on the whole, undergraduate psychology textbooks are misinforming hundreds of thousands of college students on this subject every year.
