Jensen and Bernard Davis argued that if the g factor (general intelligence factor) were replaced with a model that tested several types of intelligence, it would change results less than one might expect. Therefore, according to Jensen and Davis, the results of standardized tests of cognitive ability would continue to correlate with the results of other such standardized tests, and that the intellectual achievement gap between black and white people would remain. James R. Flynn, a researcher critical of racial theories of intelligence, repeated the arguments of Arthur Jensen about the second edition of The Mismeasure of Man. Flynn wrote that "Gould's book evades all of Jensen's best arguments for a genetic component in the black–white IQ gap, by positing that they are dependent on the concept of g as a general intelligence factor. Therefore, Gould believes that if he can discredit g no more need be said. This is manifestly false. Jensen's arguments would bite no matter whether blacks suffered from a score deficit on one or ten or one hundred factors." Rather than defending Jensen and Rushton, however, Flynn concluded that the Flynn Effect, a nongenetic rise in IQ throughout the 20th century, invalidated their core argument because their methods falsely identified even this change as genetic. According to psychologist Ian Deary, Gould's claim that there is no relation between brain size and IQ is outdated. Furthermore, he reported that Gould refused to correct this in new editions of the book, even though newly available data were brought to his attention by several researchers.
