Matching Decisions to Decision-Makers: via Our Testosterone Levels

Hormones can play a role in decision-making, particularly testosterone, which when present in high levels can lead to more utilitarian decisions being made. In a study where participants were made to answer philosophical questions involving morality, high-testosterone individuals were consistently more willing to endorse a difficult decision, if there was some ‘greater good’ involved. On the other hand, this made them more likely to violate a moral norm in doing so. So can we match decisions to decision-makers based on an individual’s chemical make-up?
