Perceptions of a defendant’s psychopathic personality traits can impact mock jurors’ decision making, yet findings on the relationship of jurors’ and defendants’ gender on legal decision making have been inconsistent. This study investigates the relationship between defendant prototypical gender-congruent or -incongruent psychopathic traits and mock jurors’ perception and sentencing recommendations. In a between-subject design, participants (N = 1,721) rendered a verdict and rated the extent to which they perceived the defendant as legally responsible, morally responsible, and their recidivism risk. Participants prescribed harsher punishments and held more negative perceptions of a defendant with psychopathic traits than a defendant without these traits. However, the defendant received similar punishment and was judged equally negatively in both gender-congruent and -incongruent conditions. Finally, while men were more likely to choose the death verdict, women held more negative views of the defendant. Thus, portrayal of psychopathic traits seems related to harsher sentencing independent of gender-specific trait variations.
