> I've related before one observational study of men picking up women in bars. When the men were prompted to act "confident," they had limited luck in getting dates. When they were told to act "arrogant" they had much better success. That's rather dismaying to me in what it says about women.

I think that it says something about what many men think "acting confident" means. It also says that you have to boost the signal in a noisy environment.
