Understanding Everyday Psychopathy: Shared Group Identity Leads to Increased Concern for Others among Undergraduates Higher in Psychopathy

Psychopathy can be considered as a dimension anchored on one end by a lack of concern for others. Even in its milder forms, psychopathy can lead to everyday antisocial behavior, such as plagiarism and cheating or getting into fistfights. Although a lack of concern for others is central to the concept of psychopathy, it is unclear whether this stems from differences in ability or motivation. In two studies, participants made decisions for themselves and others simultaneously following a manipulation of shared identity, which is known to increase the motivation for cooperative behavior. When the others were described as in-group members, participants higher in psychopathy showed greater concern for those others. This indicates that the lack of concern for others produced by everyday psychopathy is due to a lack of motivation to care about others, rather than a lack of ability to do so.
