The only snippet I'd heard about this is something to do with men having more grey matter and women (quite a bit) more white matter.
In theory anyway, grey matter focuses in or is logical or something (lol I don't know about brains ok) and white matter is good at relating different topics, but doesn't focus on one topic well.
In IQ and standardized tests though, I thought it was said men and women tend excel at different things. Of course here we go with that gender stuff again -- what bugs me is being male myself, that supposedly gives me what, a really small edge in visual-spacial intelligence when I'm averaged with 10,000 other males against 10,000 other females... but am I necessarily any better at math, taller, etc than a given female no...
I guess that's why this stuff tends to bug me, it seems like it's misleading to the individual who may tend to think because they're part of the male or female "club" that they as an individual have a small edge in such areas when those edges only show up when averaged out given large numbers of people.
Well that's certainly logical...
