====Criticism by Noam Chomsky====

In 1995, [[Noam Chomsky]], a founder in the field of [[cognitive science]], criticized the book and its assumptions on IQ. He takes issue with the idea that IQ is 60% heritable, arguing that the "statement is meaningless" because [[heritability]] does not have to be genetic. Chomsky gives the example of women wearing [[earrings]]:

{{blockquote|To borrow an example from [[Ned Block]], "some years ago when only women wore earrings, the heritability of having an earring was high because differences in whether a person had an earring was due to a chromosomal difference, XX vs. XY." No one has yet suggested that wearing earrings, or ties, is "in our genes," an inescapable fate that environment cannot influence, "dooming the liberal notion."<ref name=Rollback>[https://chomsky.info/199505__/ Rollback, Part II] Noam Chomsky, 1995</ref>}}He goes on to say there is almost no evidence of a genetic link, and greater evidence that environmental issues are what determine IQ differences.
