...study authors hypothesized that participants taking testosterone would engage in riskier, more aggressive behavior - that is, offer their fellow participant a lesser amount of money. What happened instead was that the women who received testosterone made significantly more equitable offers than those who received a placebo, offering their partners an average of 3.9 money units out of 10, vs. 3.4 money units...
...give a lizard testosterone, it becomes more aggressive. But we are not lizards. Our social interactions are nuanced and complex," explains lead author Michael Naef of the Experimental Economics Lab at Royal Holloway College at the University of London. "In many human interactions, it is social rather than antisocial behavior that secures status...

But John Coates, a former Wall Street trader and researcher at Cambridge University, warns against extrapolating too much from the study. Coates' own measurements of testosterone levels in the saliva of male traders found a link between higher levels of the hormone and risky behavior. He says there is a "dose-response curve" for testosterone...
