Abstract
Using the tenets of social cognitive theory, this study attempts to examine the potential positive relationship between trait psychopathy and group performance. The literature lacks empirical investigation into any favorable relationship between psychopathy and group performance. We propose and test a model suggesting how psychopathic tendencies positively impact group performance directly and via social and collective efficacy. We found good support for the proposed hypotheses using multi-wave and multi-sourced data collected from 506 employees comprising 81 groups. The results aligned with the expectations, indicating a strong positive connection between psychopathy and social and collective efficacy, positively impacting group performance. As expected, a negative effect has been found between the direct relationship of psychopathy and group performance such that the psychopath's group performance diminishes on the direct path. The social efficacy and collective efficacy sequentially mediate the positive effect of psychopathy on group performance.
