According to Simon Baron-Cohen (Sacha Baron Cohen's psychologist cousin) men tend towards systemizing, which basically means they're more interested in stuff and how stuff works, while women tend toward empathizing, which means they're more interested in people and what makes them tick.

On his scale autistic people have the most macho brains while psychotic people have the most feminine brains. It's true that most people on the autistic spectrum (something like 80 percent) are men (though some people speculate there's more autistic women than is commonly believed by researchers), but people with psychotic disorders like bipolar and schizophrenia are about equally likely to be male or female, and if anything may have a slight male surplus as well for whatever reason.

Like men compared to women, autistic people tend to be more self centered than neurotypical people (I'm not saying they are bad people, they're just mentally less involved with thinking about others). Psychotic people on the other hand are constantly thinking about others and what their intentions might be, to the point of paranoia.

In your experience, does it ring true that men are more into "stuff" and women are more into people? Do you think the characteristics of autistic people (sensitivity to physical stimuli, a low threshold for frustration, missing key social cues, special interests) can be generalized to neurotypical men if it's a given these traits are present to a lesser degree? Can psychotic characteristics (heightened pattern recognition, high alertness to potential threats, reading more into people's actions than is probably there) be generalized about women if it's given these traits are present to a lesser degree?
