Hormones influence morality by
modulating the emotional and cognitive processes underlying moral judgments, though the research is still developing and complex. For example, testosterone is linked to more utilitarian, outcome-focused decisions, potentially by reducing empathy or increasing a drive for status, while oxytocin may promote trust, affiliation, and emotional responses relevant to "caring for others". Cortisol, the stress hormone, has shown a negative association with altruism in emotionally charged situations. However, these relationships are nuanced, with individual differences and environmental factors playing a moderating role, and some studies show conflicting results.
