The social identity theory of leadership: Theoretical origins, Research findings, And conceptual developments

Over the past decade the social identity theory of leadership (Hogg, 2001a; Hogg & van Knippenberg, 2003) has reinvigorated social psychological research on leadership by reconnecting leadership to the social psychology of influence, and by explicitly elaborating on the (social) identity function, and associated social cognitive and social interactive processes, associated with leadership. The main tenet is that group prototypical leaders are better supported and more trusted, and are perceived as more effective by members than are less prototypical leaders; particularly when group membership is a central and salient aspect of members’ identity and members identify strongly with the group. This hypothesis has attracted unequivocal support across numerous studies, research teams, and research paradigms. In this article we describe the social identity theory of leadership and its conceptual origins, and overview the state of evidence. The main focus of the article is on new conceptual developments and associated empirical advances; including the moderating roles of uncertainty, group innovation and creativity, deviance, ‘‘norm talk’’, charisma, fairness, as well as the extension of the social identity theory of leadership to an intergroup context. Throughout we identify directions for future empirical and conceptual advances.
