Pictures of Sexy Women + Studly Men = Poor Bargaining

Hmm.. I'm noticing a subject matter trend here for me...

"It seems that the more macho a man is, at least according to his hormones, the more the sight of an attractive woman will affect his judgement."
"Researchers at the University of Leuven in Belgium asked men to play an ultimatum game, in which they split a certain amount of money between them. High-testosterone men drove the hardest bargain, unless they had previously viewed pictures of bikini-clad models, in which case they were more likely to accept a poorer deal. The sight of flesh had less effect on the bargaining tactics of low-testosterone men."

I don't think I agree with their reasoning as to why men become less aggressive when a beautiful woman is present.

"The sight of a potential mate might therefore actually make men more sensible, Van den Bergh says. "Since a few coins is better than no coins at all, men thus become more economically rational after exposure to lingerie or sexy women," he says."

This seems a little counter intuitive since it makes more sense to assume that men would want to come out ahead of someone else to show their "prowess" to a beautiful woman. This could totally be an effect of attention - men are thinking about sex more than the task at hand...Bargaining.
