Does Testosterone Effect Economic Preferences? This paper says no:

Participants were randomly allocated to receive a single dose of either placebo or intranasal testosterone. They thereafter carried out a series of economic tasks capturing social preferences, competitiveness and risk preferences. We fail to find any evidence of a treatment effect for any of our nine primary outcome measures, thereby failing to conceptually replicate several previous studies reporting positive findings that used smaller sample sizes. In line with these results, we furthermore find no evidence of an association between basal testosterone and economic preferences, failing to also conceptually replicate previous correlational studies.

People really love the nature account, possibly because it absolves us of personal responsibility. But nature is nurture and vice versa, and genetics always seems to get pushed further into the margins.V
