Battling ingroup bias with effective intergroup leadership.

Abstract

Intergroup conflict and bias often occur between subgroups nested within a superordinate group. In these situations, the leader of the superordinate group plays a key role, as an intergroup leader, in reducing conflict. To be effective, an intergroup leader should avoid (1) threatening the subgroups' distinctive identities, and (2) being viewed by one or both groups as ‘one of them’ rather than ‘one of us’. Intergroup leadership theory (Acad Manag Rev, 37, 2012a, 232) posits intergroup leaders can improve subgroup relations by promoting an intergroup relational identity. Two studies (Ns = 178 and 223) tested whether an out‐subgroup or in‐subgroup leader could improve intergroup attitudes, even among strong subgroup identifiers, by promoting either an intergroup relational identity or a collective identity. We hypothesized an interaction of these variables demonstrating the effectiveness of an intergroup relational identity message for an out‐subgroup leader in lessening ingroup bias, especially among strong subgroup identification. Our results, and a meta‐analytic summary across both studies (N = 401), supported our hypothesis and intergroup leadership theory, demonstrating an intergroup relational identity is an effective strategy for improving intergroup relations.
