The Impact of Group Norms and Generalization of Risks across Groups on Judgments of War Behavior

This paper investigates the effects of war experiences across three different levels (individuals, groups, and contexts) on moral judgments related to violations of humanitarian norms. Competing hypotheses derived from different theoretical perspectives are empirically evaluated. Social psychological studies of war traditionally highlight a reversal of morality and group norms justifying violence against outgroups. Rationalistic models insist on the importance of realistic costs on the choice of individuals. As a complement to these traditions, we suggest that situations in which risks are generalized across group boundaries tend to provoke a strengthening of principles, such as humanitarian norms, that enable the protection of the material and symbolic integrity of a community. Multilevel analyses of the international People on War survey dataset (N = 8,121) show that support for the ingroup's struggle, at both individual and group levels, predicts stronger justification of violence. Simultaneously, at the context level, generalization of war‐related risks predicts stronger condemnation of violations of humanitarian principles. These findings are consistent with a collective vulnerability model and, only in part, with the intractable conflict model.     

Creative innovation or crazy irrelevance? The contribution of group norms and social identity to creative behavior

This paper develops an analysis of innovative behavior and creativity that is informed by the social identity perspective. Two studies manipulated group norms and analyzed their impact on creative behavior. The results of Study 1 show that when people are asked to make a creative product collectively they display conformity to ingroup norms, but that they deviate from ingroup norms when group members make the same products on their own. A parallel result was found in group members’ private perceptions of what they consider creative. In Study 2, the social identity of participants was made salient. Results showed conformity to group norms even when group members worked on their own creations. Findings suggest that innovative behavior is informed by normative context, and that in contexts in which people operate as members of a group (either physically through collective action, or psychologically through social identity salience) innovation will respect normative boundaries.     

Portraits in painting and photography

In this paper, we offer an analysis of ‘group intentions.’ On our proposal, group intentions should be understood as a state of equilibrium among the beliefs of the members of a group. Although the discussion in this paper is non-technical, the equilibrium concept is drawn from the formal theory of interactive epistemology due to Robert Aumann. The goal of this paper is to provide an analysis of group intentions that is informed by important work in economics and formal epistemology.     

Group transformation: How demonstrability promotes intra-group cooperation in social dilemmas

Intra-group cooperation in a social dilemma is increased after a group has discussed and reached a decision, especially if the dilemma is easily understood (‘demonstrable’). This paper examines how demonstrability affects the decision of a group that consists entirely of participants who are initially non-cooperative. Thirty-eight 6-person groups with unanimous prior preference for cooperation or non-cooperation discussed a prisoner’s dilemma before making a group decision. When demonstrability was low groups reflected the prior (either cooperative or non-cooperative) preferences of their members. When demonstrability was high we found that groups showed no effect of prior preference. Specifically, groups of prior non-cooperators made more cooperative group decisions and subsequently their members remained cooperative when asked to express preferences individually. The combined advantages of group process and high demonstrability for facilitating optimal cooperation are discussed.     

The impact of individualist and collectivist group norms on evaluations of dissenting group members

Two experiments were conducted to investigate the impact of individualist and collectivist norms on evaluations of dissenting group members. In the first experiment (N = 113), group norms prescribing individualism or collectivism were manipulated and participants were asked to evaluate a group member who expressed an attitude dissenting from or concordant with the group. In line with predictions, group members with concordant attitudes were evaluated more positively than group members with dissenting attitudes when norms prescribed collectivism. However, for high identifiers, we found an attenuation of the preference for concordant over dissenting attitudes when norms prescribed individualism. These findings were replicated in a second experiment (N = 87), where dissent was operationalized in a way that did not reveal the content of the attitude. The discussion focused on the importance of individualist norms for broadening latitudes of acceptable group member behavior.     

Still underdetected – Social norms and collective efficacy predict the acceptance of electric vehicles in Germany

The role of social identity variables for predicting environmental decisions may often be underdetected by psychological lay people. Applying this to the acceptance of electric vehicles (EVs) in Germany we investigated whether social norms and collective efficacy predict EV acceptance and what psychological laypersons who are either EV experts or EV non-experts think predicts EV acceptance. In preliminary interview studies we explored the beliefs of EV experts and EV non-experts. In a survey study, we then tested whether cost-related advantages and disadvantages were predictive of EV acceptance and whether norms and collective efficacy have independent effects even when controlling for cost-related factors and demographic variables. Results suggest that both EV experts and EV non-experts considered cost-related factors as much more important than social identity processes. However, hierarchical regression analyses of the survey data showed that norms and collective efficacy have equal or even stronger effects on acceptance than cost-related factors. We discuss the theoretical and practical implications of these findings.     

Cues to intention: the role of movement information

Body movement provides a rich source of cues about other people’s goals and intentions. In the present research, we investigate how well people can distinguish between different social intentions on the basis of movement information. Participants observed a model reaching toward and grasping a wooden block with the intent to cooperate with a partner, compete against an opponent, or perform an individual action. In Experiment 1, a temporal occlusion procedure was used as to determine whether advance information gained during the viewing of the initial phase of an action allowed the observers to discriminate across movements performed with different intentions. In Experiment 2, we examined what kind of cues observers relied upon for the discrimination of intentions by masking selected spatial areas of the model (i.e., the arm or the face) maintaining the same temporal occlusion as for Experiment 1. Results revealed that observers could readily judge whether the object was grasped with the intent to cooperate, compete, or perform an individual action. Seeing the arm was better than seeing the face for discriminating individual movements performed at different speeds (natural-speed vs. fast-speed individual movements). By contrast, seeing the face was better than seeing the arm for discriminating social from individual movements performed at a comparable speed (cooperative vs. natural-speed individual movements, competitive vs. fast-speed individual movements). These results demonstrate that observers are attuned to advance movement information from different cues and that they can use such kind of information to anticipate the future course of an action.     

On collective intentions: collective action in economics and philosophy

Philosophers and economists write about collective action from distinct but related points of view. This paper aims to bridge these perspectives. Economists have been concerned with rationality in a strategic context. There, problems posed by “coordination games” seem to point to a form of rational action, “team thinking,” which is not individualistic. Philosophers’ analyses of collective intention, however, sometimes reduce collective action to a set of individually instrumental actions. They do not, therefore, capture the first person plural perspective characteristic of team thinking. Other analyses, problematically, depict intentions ranging over others’ actions. I offer an analysis of collective intention which avoids these problems. A collective intention aims only at causing an individual action, but its propositional content stipulates its mirroring in other minds.     

Intuitive theories of group types and relational principles

Three studies investigated perceivers’ beliefs about the principles by which different kinds of social groups govern interactions among group members. In Study 1, participants rated a sample of 20 groups on a set of group properties, including measures of relational principles used within groups. Results showed that people believe that interactions in different types of groups are governed by different blends of relational principles unique for each type of group. Study 2 experimentally demonstrated that perceivers could use minimal group property characteristics of different types of groups (i.e., extent of group member interaction, group size, duration, and permeability) to make inferences about the relational principles used in different types of groups. Study 3 demonstrated that relational style information influences people’s judgments of a group’s entitativity and collective responsibility.     

But Affirmative Action hurts Us! Race-related beliefs shape perceptions of White disadvantage and policy unfairness

Drawing on social identity theory, we examine how Whites’ race-related beliefs drive their reactions to race-based Affirmative Action Policies (AAPs). Across laboratory and field settings, we find that Whites with relatively high modern racism (MR) or collective relative deprivation (CRD) beliefs perceive greater White disadvantage in organizations that have race-based AAPs, than in organizations that do not. Alternatively, race-based AAPs do not lead to perceptions of White disadvantage among Whites with relatively low MR and CRD beliefs. We also find that White disadvantage mediates the relationship between the combined effects of race-based AAPs, MR beliefs, and CRD beliefs and the perceived fairness of the organization’s selection and promotion policies. Our findings suggest that race-based AAPs do not necessarily lead to perceptions of White disadvantage, but are contingent upon the interpretive lens of Whites’ MR and CRD beliefs, and also offer practical insights for preventing negative reactions to race-based AAPs.     

Can confidence come too soon? Collective efficacy,conflict and group performance over time

Groups with a strong sense of collective efficacy set more challenging goals, persist in the face of difficulty, and are ultimately more likely to succeed than groups who do not share this belief. Given the many advantages that may accrue to groups who are confident, it would be logical to advise groups to build a high level of collective efficacy as early as possible. However, we draw on Whyte’s (1998) theory of collective efficacy and groupthink, to predict that when confidence emerges at a high level toward the beginning of a group’s existence, group members may be less likely to engage in process conflict; a form of conflict that may be beneficial in the early phase of a group project. We found support for this prediction in two longitudinal studies of classroom project teams.
