Heterogeneity and centrality of "dark personality" within teams, shared leadership, and team performance: A conceptual moderated-mediation model

Shifting from the much-studied five-factor model of personality, this paper focuses on dark personality (i.e. the "Dark Triad": Machiavellianism, psychopathy, and narcissism) to advance understanding of team composition, processes, and performance. The research responds to a call to explore dark personality's manifestation within - and impact on - teams. Specifically, this paper will examine the impact of within-team heterogeneity in dark personality on team performance, with shared leadership as mediator of this relationship. Additionally, I propose two moderators of the relationship between within-team dark triad heterogeneity and shared leadership - team network centrality of the team member scoring highest on the Dark Triad, and team mean Dark Triad score. This research aims to make a uniquely valuable contribution to scholarship on leadership within teams through bridging literatures on social network analysis, teams, leadership, and the dark triad and should have implications for team selection and performance.
