Intergroup and intragroup aspects of leardership in social dilemmas: A relational model of cooperation

Two experiments investigated how leadership shapes individual contributions in small groups facing public goods dilemmas. We predicted that the influence of leaders would be determined by their ability to fulfill both instrumental needs (solve the free-rider problem) and relational needs (contribute to the identity) of group members. The relative importance of these two needs was expected to vary with the salience of group membership (social vs personal identity). This hypothesis was supported in two experiments. Experiment 1 revealed that leaders showing group commitment and fairness toward members were more effective at raising contributions when social identity was salient. Furthermore, Experiment 2 showed that highly committed leaders were more influential when social identity was salient, whereas leaders with intrinsic leadership skills were more influential when personal identity was salient. This suggests that the effectiveness of leader solutions to social dilemmas depends upon the fit between leader characteristics and member expectations.
