Employing the principles of social cognitive theory, this study treats psychopathy as both a trait and an agentic process, rather than conceptualizing personality solely as a cluster of specific traits. This study entrenched the grand challenge and attempted to examine the efficacy and dark traits as dynamic personality concepts. Study has used social and collective efficacy as interventions of psychopathy personality traits to promote its potential positive effect at group performance. The literature lacks any favorable relationship between psychopathy and group performance. The study propose and test a model suggesting how psychopathic tendencies positively impact group performance directly and via social and collective efficacy. Study found good support for the proposed hypotheses using multi-wave and multi-sourced data collected from 506 employees comprising 81 groups of 29 service-oriented companies in Pakistan. 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 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.
