Abstrakt: Psychopaths are suggested to be more likely to favor utilitarian outcomes over non-utilitarian (i.e., deontological) choices. Here we re-test this hypothesis and investigate whether oxytocin, a hormone associated with empathy, can counter this utilitarian effect. Forensic psychopathic patients and non-psychopathic controls participated in a sacrificial moral decision-making paradigm. Psychopathic patients performed the task in a double-blind cross-over placebo-controlled oxytocin administration paradigm. We found no evidence for psychopathic patients to act more utilitarian (or sacrificial) or any effect of oxytocin administration. Psychopathic traits within the control group, particularly traits associated with lack of empathy and failure to consider consequences, were however associated with more utilitarian choices, but only when these actions were low in emotion. In contrast, psychopathy severity in psychopathic patients, particularly impulsivity-related traits, predicts deontological choices, but only in highly emotional actions. Thus, although psychopathic traits do predict utilitarianism when emotional investment is low, this is not the case in full-blown psychopathy. Instead, there is a link between impulsivity and deontological choices in psychopathic patients, but only when emotional investment is high, and self-interest is not at stake. These preliminary results are discussed to whether utilitarian outcomes align with the personal goals of psychopathic individuals.
