Previous research has demonstrated that intra-group respect can strengthen people's group identification, and encourage them to exert themselves on behalf of their group. In the present contribution, we focus on the possibility that those who are not respected by other group members (i.e., the disrespected) can also display group beneficial behavior. Experiment 1 (N = 159) confirms this paradoxical premise and reveals that systematically disrespected group members indeed exert themselves on group-serving tasks. These findings were replicated in Experiment 2 (N = 110). Additional indicators in Experiment 2 demonstrate that the effort by systematically disrespected group members cannot be attributed to a desire to improve their acceptance in the group, but should be interpreted as attempts to assert the worth of the self separately from the group. Results are discussed in relation to the group-value model and insights on marginal group membership and social exclusion. © 2005 Elsevier Inc. All rights reserved.
