Imagine that Group A tests as being better at task X and therefore is viewed as being “smarter”.
But then we find that Group B tests as being better at task Y.
Notice that we have already presupposed that task Y is not important to the definition of “intelligence”. But why not?
If women wrote the IQ tests, would it still remain true that playing chess well is more important to “being smart” than communicating effectively?
What about from a societal level? Are we really able to say with any certainty that we need people who can do math more than we need people who are capable of empathy, or multitasking, or any of the traits where women are believed to outshine men?
Women and men are different, and we benefit from having both. Why then would we not also believe that people from different ethnic backgrounds might also bring complimentary benefits, even if it is true that Group A is “smarter” than Group B according to traditional measures?
If mothers had written the first IQ tests, would they have written one test for their sons and a different one for their daughters?
