(Not read the article, apologies if I miss something.) >They take more risks because it works. Agreed. >I doubt it has anything to do with testosterone, and much more to do with perceived reward This makes it seem like a conscious decision, which I don't buy. "Pretty woman will like me" is just one more factor in the risk/reward calculation, which is made subconsciously. I would say it's more likely that testosterone is one variable in the risk/reward calculation, and is released in the presence of pretty women (among other things) because that turns out to be what works.
