That’s obviously not true, men don’t have 7x more grey matter.

> In general, men have approximately 6.5 times the amount of gray matter related to general intelligence than women, and women have nearly 10 times the amount of white matter related to intelligence than men.

    > This means that the brain differences between large- and small-headed men are as great Well, kind of like a shorter male is still shorter than a taller male yet males are taller than females on average ... which makes it a bit of a 'duh' assessment. Obviously these are distributions. > And importantly, none of these size-related differences can account for familiar behavioral differences between men and women, such as empathy or spatial skills. That's a rather unscientific assertion and certainly false, besides the fact that it doesn't even seem to follow from the study itself. If more gray matter by itself already explains autism, then certainly the gray matter and brain size differences between the sexes must account at least in part for similar cognitive and behavioral differences between the sexes.

  The key part here is "related to general intelligence" (not sure how they measured that as I haven't read the whole study). They obviously don't have 6.5 times more gray matter as a whole.

    What do you mean by 'obviously' here? How precisely has that manifested to you in such obvious manner? Genuinely curious since you seem to take that as a given.
