False ? Are you sure ?

You've pointed above to this article. If you'll bother to read it to the "see also" list you'll find this link where you can read that "modern studies using MRI have shown that brain size shows substantial and consistent correlation ( r = .35 to .43 in various studies) with IQ among adults of the same sex" - with pointers to said studies. As for adults of different sexes - it's much harder to measure without bias, but it's not clear why there should not be a difference...

Of course "there's a lot inside a skull other than just the brain" and social factors are 100 times more effective segregation factor then small inborn difference in intelligence...
