I think what happens is that researchers often don't report on - or at least don't highlight - uninteresting results, partly because of the difficulty getting uninteresting results published. So given that gender differences in IQ in general are eliminated for validity, a lack of gender differences in IQ amongst a seemingly arbitrary sub-population such as ...
