Now, admittedly I haven't seen a whole lot of evidence in this area, but I've seen some, and I couldn't name a single woman I know personally who has ever, in my presence or by report that I've heard, gone for a jerk.

I could name a fair number (in the "doesn't care about hurting others" sense, not the "wears motorcycle jackets" sense,) but none of them have been girls or women I would want to date me instead.

I suspect that the perceived trend owes a lot to a horns effect that guys build up around other guys who're dating girls they want to be dating.
