Women tend to be analytical, thus the constant threats of your gf leaving you because she found a pink cupcake and you'd totally not eat something pink. Problem is they focus it on things like that instead of anything with substance. Or, if it is focused on something worthwhile, things get so overanalyzed they become repetitive and the data convoluted by circles. Risk taking also ties in here, most women won't just accept their first highly feasible result.
I feel like women's intelligence is more socially tuned, while male is more for tool use and hunting. Obviously women also do those things and men also socialize, but each one does more of one.
So men tend to zoom in on the explicit things that can lead them to a certain conclusion, whereas women tend to take in loads of information and shuffle around all of the possibilities. I think in hunting, simple, straightforward rationality is the way to go, while in maintaining favor in your social group, you have to be aware of a bunch of possibilities at once (like when you want to say something to a group of people, but one person's gonna take it x way and you don't want them to, so you word it differently, but then another person is gonna take it y way, so you word it differently again).
Besides, early hominids were about three feet tall and other mammals were way bigger, so you had to be as logical as possible. If you left anything to chance, you could get stomped to death by some animal (the brute force of a three foot tall ape that is the weakest out of all apes doesn't do much against a 140+ pound wolf).
But then again, humans are pretty malleable behaviorally. Human males can be less violent than chimp females (who will murder each other's babies).
Anyways, I feel like this is why the typical miscommunications between the sexes I tend to hear are "why are women so complicated/crazy," and "why are men so stupid?" Men get mad that women don't see about the explicits of a situation, which leads to things like, "you're not ugly, I'm obviously into you." Whereas women get mad that men don't see the implications, like that how attractive they feel isn't necessarily about how attracted to them you are. (Yes this is from experience)
