Also, this just in, women love jerks.
In high school, I found this truism to be particularly bewildering. WTF? Why? What is going on with this?
IMO, a few things at play there:
There is an element of danger, or excitement, in dating a jerk.
Being a jerk often gives the illusion of commanding authority, which can be an attractive quality.
Some women, especially when younger, see it as a challenge. A really good looking guy with a personality problem can be "changed".
I think, in general, jerks tend to draw more attention to themselves then a confident but soft spoken person who walks the walk rather then talks the talk. Those types tend to fly under the radar and go unnoticed. Most teenagers are shallow. Most out-grow that phase.
And finally, and most importantly, women are crazy, there really isn't any rational reason for why they do anything :-).
