Research shows that money favors the men.
Little is known about the role of the endocrine system in financial risk taking. Here, we report the findings of a study in which we sampled, under real working conditions, endogenous steroids from a group of male traders in the City of London. We found that a trader’s morning testosterone level predicts his day’s profitability. We also found that a trader’s cortisol rises with both the variance of his trading results and the volatility of the market. Our results suggest that higher testosterone may contribute to economic return, whereas cortisol is increased by risk. Our results point to a further possibility: testosterone and cortisol are known to have cognitive and behavioral effects, so if the acutely elevated steroids we observed were to persist or increase as volatility rises, they may shift risk preferences and even affect a trader’s ability to engage in rational choice.
I will refrain from comment.

Yep. Very similar to how Sarah Palin seems to affect many supposedly rational men. (Hormonal: Not just for women anymore.)
I think it’s the glasses.
Susan Hutchinson, the local Republican Sarah Palin clone, does nothing for me.
Brendan, don’t be an idiot.
Read the paper. They used 18 men. Only men.
No tests of women were made.
It also seems to look at within-subject data, so within a single guy, as testosterone varies, so does his success at the market.
