Women are nicer than men. I'm sure most people will agree. Of course there are the nasty, heartless, scheming ones -- but there are plenty of men who fit that description. On average, though, women are better at empathizing with others, and better at picking up on others' moods and caring about how they are doing.
Men, meanwhile, are better at analyzing systems and building things.
That's how natural selection made our brains.
