What do you think?
As I said, the jerk could be goofy or "cool". The latter is basically another way of saying "confident". I agree that the underlying image of (real or fake) confidence is a big part of the attraction. However, the "aggressive" part has its own independent contribution, based on evolutionary pressures, as I indicated before. The same evolutionary pressures can result in more than one "solution", and the degree and kind of evolutionary pressure can vary from place to place, hence the variety of "tastes". No need to overdo this analysis. I just wanted to state that many apparently curious human behaviors can be explained in terms of evolutionary processes.
