Psychopathy and Moral-Dilemma Judgment: An Analysis Using the Four-Factor Model of Psychopathy and the CNI Model of Moral Decision-Making

A major question in clinical and moral psychology concerns the nature of the commonly presumed association between psychopathy and moral judgment. In the current preregistered study (N = 443), we aimed to address this question by examining the relation between psychopathy and responses to moral dilemmas pitting consequences for the greater good against adherence to moral norms. To provide more nuanced insights, we measured four distinct facets of psychopathy and used the CNI model to quantify sensitivity to consequences (C), sensitivity to moral norms (N), and general preference for inaction over action (I) in responses to moral dilemmas. Psychopathy was associated with a weaker sensitivity to moral norms, which showed unique links to the interpersonal and affective facets of psychopathy. Psychopathy did not show reliable associations with either sensitivity to consequences or general preference for inaction over action. Implications of these findings for clinical and moral psychology are discussed.
