The present thesis investigates two theoretically novel processes of change in groups relevant to agents for change. Specifically, it examines the effects of group opinion change and reintegration on group members’ evaluation of ingroup change-agents. Group opinion change is operationalized as the group adopting the position advocated by a change-agent, and reintegration is operationalized as the group responding more positively towards a change-agent. These formulations of change processes within groups extend past theorizing in opinion deviance research (e.g., Festinger, 1950; Schachter, 1951; Marques & Paez, 1994) by a) examining how contextual differences that result from changes in the group may affect group members’ reactions to opinion deviates, and b) considering contingencies that result in acceptance or rejection of change-agents and their messages. In addition, this thesis investigates the psychological processes that may mediate and moderate the effects of group opinion change and reintegration on appraisals of change-agents. Specifically, it considers attributed motives of change-agents (i.e., perceived constructiveness; Hornsey, 2005), and target prototypicality (e.g., Hogg, 1993; Turner, Hogg, Oakes, Reicher, & Wetherell, 1987) as two possible mediators of these novel effects. Finally, group members’ identification with the group is examined as a moderator of these processes. Chapter 3 presents the first two experiments that tested the effects of group opinion change on the evaluation of change-agents. Experiment 1 (N=100) was a scenario-based study that had a change-agent express a non-conformist view of giving water to an outgroup state at a time when the ingroup state was experiencing a water crisis. Experiment 2 (N=103) was a scenario-based study that looked at a change-agent who expressed pro-immigration views to the ingroup country at an earlier time when popular attitudes toward immigration were poor. In both experiments the deviants were marginalized initially because they endorsed non-conformist opinions. Depending on the condition, group opinions either shifted toward the positions advocated by the deviants or remained unchanged. Results showed group members’ target evaluations shifted as a function of group opinion change. Target evaluations became less favourable in Experiment 1, and more favourable in Experiment 2. There also was evidence that increased perceived constructiveness mediated more favourable target evaluations in Experiment 2. Chapter 4 presents the first two experiments that tested the effects of reintegration and group members’ identification on the evaluation of change-agents. Both Experiments 3 (N=103) and 4 (N=94) involved a scenario where there was a severe drought in the ingroup state. In Experiment 3, a deviant politician argued for more investment on water infrastructure 10 years earlier when water shortage was not a critical problem. Thus, the politician expressed a minority opinion. In Experiment 4, a deviant water commissioner expressed a controversial opinion to give water to an outgroup state at the height of the drought. Both deviants were marginalized/excluded initially by the group. Reintegration was manipulated by showing that popular support for the deviant had increased (Experiment 3) or the deviant was reinstated (Experiment 4), or the group did not increase support for the deviant at all (not reintegrated). Results showed that high identifiers evaluated the deviant less positively, and perceived the deviant as more destructive after he or she was reintegrated than when marginalization continued. Further, perceived destructiveness mediated the effects of reintegration and identification on trait evaluations. Experiment 4 also showed that high identifiers were less willing to support change after the deviant was reintegrated, than when marginalization continued. Finally, Chapter 5 tested the interactive effects of group opinion change and reintegration on evaluation of change-agents. I also assessed group members’ responses to change-agents in light of the group’s resistance to change even though the change-agents were right and the groups were wrong. Experiment 5 was a scenario-based study in a minimal-groups situation that had a deviant arguing for a more equitable research funding than the existing distribution. Experiment 6 was a scenario-based study on the disagreement between Galileo Galilei and the Catholic Church on planetary motion. Again, the deviants initially were marginalized by the groups. For opinion change, the groups either adopted or rejected the deviants’ opinions. For reintegration, the groups either treated the deviants more favourably or continued to reject them. Results showed that either opinion change or reintegration was sufficient to defuse negativity towards the deviants. More importantly, group members continued mistreating the deviants when the groups rejected opinion change and reintegration. That is, negativity towards the deviants was highest when opinion was unchanged, and marginalization continued. Overall, this thesis shows that group members’ evaluations of deviant agents for change can shift as a function of group opinion change and reintegration. Group opinion change and/or reintegration defuse negativity toward change-agents in the absence of psychological threat (i.e., perceived destructiveness). However, if threat is present, opinion change or reintegration may ironically elicit more group members’ negativity towards these targets. This thesis also contributes to the literature by showing how change promotes or inhibits group members’ endorsement of change-agents.
