An experiment was run to test if a testosterone administration would influence the political preferences of 136 healthy males.
Synthetic testosterone or placebo was administered to participants who identified the strength of their political affiliation.
Before the testosterone treatment, we found that weakly affiliated Democrats had 19% higher basal testosterone than those who identified strongly with the party (p = 0.015). When weakly affiliated Democrats received additional testosterone, the strength of their party affiliation fell by 12% (p = 0.01), and they reported 45% warmer feelings towards Republican candidates for president (p < 0.001). Testosterone administration did not affect political preferences for strongly affiliated Democrats or strong or weak Republicans.
Our results demonstrate that testosterone induces a "red shift" among weakly affiliated Democrats, providing evidence that testosterone affects political preferences.
进行一项实验，以测试睾酮给药是否会影响136名健康男性的政治偏好。
向参与者施用合成睾酮或安慰剂，这些参与者确定了他们政治归属的强度。
在睾酮治疗前，我们发现弱党派认同的民主党人的基础睾酮水平比那些强烈认同该党的人高19%（p = 0.015）。当弱党派认同的民主党人接受额外的睾酮时，他们的党派认同强度下降了12%（p = 0.01），并且他们报告对共和党总统候选人的好感度提高了45%（p < 0.001）。睾酮给药对强烈党派认同的民主党人或强弱程度不同的共和党人的政治偏好没有影响。
我们的结果表明，睾酮在弱党派认同的民主党人中引发了“红色转变”，为睾酮影响政治偏好提供了证据。
