I remember taking it in college and thinking even then, when I had respect for psychology, that it probably was not a useful measure of anything. One quote toward the beginning made me chuckle, which is partly why I'm sharing: ". . . the IAT falls far short of the quality-control standards normally expected of psychological instruments . . . The history of the test suggests it was released to the public and excitedly publicized long before it had been fully validated in the rigorous, careful way normally demanded by the field of psychology." Oh, yes, those rigorous standards . . .
