It may seem rather far-fetched to say that testosterone supplements affect moral judgment or reasoning. After all, these supplements are usually prescribed to help relieve symptoms of hypogonadism (excessively low testosterone), as well as used off-label by men who are worried about low testosterone.<\/p>\n
Yet that\u2019s what the results of some studies are suggesting. More specifically, the authors of a new study at the University of Texas at Austin propose that testosterone supplements can make men more sensitive to moral norms.<\/p>\n
According to Bertram Gawronski, a psychology professor at the University of Texas at Austin, \u201cThere\u2019s been an increasing interest in how hormones influence moral judgments in a fundamental way by regulating brain activity.\u201d In this new study, researchers evaluated the impact of testosterone on moral judgment by presenting situations to participants after they had been given testosterone or a placebo.<\/p>\n
In the double-blind study, testosterone was given to 100 participants and placebo was given to another 100 subjects. The participants were then presented with the following situation: a runaway trolley will kill five individuals unless someone chooses to pull a lever that will send the trolley to a different track, which will kill one person. Essentially, the situation was whether to allow five individuals to die or only one.<\/p>\n
The authors noted that \u201ccounter to predictions, testosterone administration led to increased inaction in moral dilemmas where harmful actions prohibited by moral norms increase overall well-being.\u201d In contrast, other analyses indicates that \u201chigher levels of endogenous testosterone [naturally occurring testosterone] were associated with lower sensitivity to moral norms.\u201d<\/p>\n
The researchers suggested that a reason for the difference between moral judgment responses from exogenous (supplemental) and endogenous testosterone may be because individuals with certain personality characteristics tend to have different levels of testosterone.\u00a0<\/strong><\/p><\/blockquote>\n
According to Gawronski, the findings of this study challenge some of the main hypotheses about how testosterone affects moral judgments. He emphasized that their results \u201cecho the importance of distinguishing between causation and correlation in research on neuroendocrine determinants of human behavior,\u201d since the impact of testosterone supplementation on moral judgments can be the opposite of that seen with endogenous testosterone.<\/p>\n
Bottom line<\/strong><\/h2>\n
Use of testosterone supplements may have an impact on a man\u2019s moral judgment and reasoning that differs from that observed with naturally occurring hormone. As another point of interest, it also turns out that other research has found the same thing seems to be true for women.<\/p>\n
