They aren't always charming and intelligent, sometimes they are repulsive and brutal.

I'd say the big warning signs are cruelty, a repulsion of weakness while also finding it irresistible, rapidly changing tactics (sometimes within seconds) that shift between dominance and attempting to garner empathy that begin to appear shallow after the first few salvos, highly manipulative to ends that don't really matter, and always "clever".

I agree, but I immediately avoid the one's that exhibit negative traits. The problematic ones for me are those that are charming and intelligent. I forgot about the rapidly changing tactics within seconds. That's really astonishing when you see it. I've never met a psychopathic woman. The couple crazy girlfriends I've had were borderline personalities, which I found even more difficult to deal with.

There are plenty of female psychopaths out there. The difference is that women are more socialized than men (hiding more obvious traits) and they seldom take the macho (sometimes violent) route to feed their egos.
