“Scientific racism” is a slur in the academy, roughly analogous to calling something “psuedoscientific” in the mainstream scientific community. Largely because there are observed differences in the results of IQ tests of different races, it is politically correct in many academic circles to refer to general intelligence under the euphemism “whatever it is that IQ tests measure.”
And, in fact, it’s solid science that performance on such tests is strongly influenced by individuals’ own perceptions of their ability. Blacks taking a test that is presented as a “laboratory exercise” outperform those taking the same test presented as an exam. In Predictably Irrational, Dan Ariely relates an even more intriguing experimental result. Researchers seeking to understand the effect that stereotypes have on math test performance decided to see if they could study the interaction between two conflicting stereotypes: that Asians are good at math; and that women are bad at it.
