Cooperative and conformist behavioural preferences predict the dual dimensions of political ideology

Decades of research suggest that our political differences are best captured by two dimensions of political ideology. The dual evolutionary framework of political ideology predicts that these dimensions should be related to variation in social preferences for cooperation and group conformity. Here, we combine data from a New Zealand survey and a suite of incentivised behavioural tasks (n = 991) to test whether cooperative and conformist preferences covary with a pair of widely used measures of the two dimensions of political ideology-Social Dominance Orientation (SDO) and Right Wing Authoritarianism (RWA)-and related policy views. As predicted, we find that cooperative behaviour is negatively related to SDO and economically conservative policy views, while conformist behaviour in the form of social information use is positively related to RWA and socially conservative policy views. However, we did not find the predicted relationships between punitive and rule following behaviours and RWA or socially conservative views, raising questions about the interpretation of punishment and rule following tasks and the nature of authoritarian conformist preferences. These findings reveal how cooperative and conformist preferences that evolved to help us navigate social challenges in our ancestral past continue to track our political differences even today.

Can ingroup love harm the ingroup? Collective narcissism and objectification of ingroup members

We examined how collective narcissism (a belief in ingroup greatness that is underappreciated by others) versus ingroup identification predicts treatment of ingroup members. Ingroup identification should be associated with favorable treatment of ingroup members. Collective narcissism, however, is more likely to predict using ingroup members for personal gain. In organizations, collective narcissism predicted promoting one’s own (vs. group) goals (prestudy: N = 179), and treating coworkers instrumentally (Study 1: N = 181; and longitudinal Study 2: N = 557). In Study 3 ( N = 214, partisan context), the link between collective narcissism and instrumental treatment of ingroup members was mediated by self-serving motives. In the experimental Study 4 ( N = 579, workplace teams), the effect of collective narcissism on instrumental treatment was stronger when the target was an ingroup (vs. outgroup) member. Across all studies, ingroup identification was negatively, or nonsignificantly, associated with instrumental treatment. Results suggest that not all forms of ingroup identity might be beneficial for ingroup members.

Tell Me Who You Vote for, and I'll Tell You Who You Are? The Associations of Political Orientation With Personality and Prosocial Behavior and the Plausibility of Evolutionary Approaches

Blatantly observable in the U.S. currently, the political chasm grows, representing a prototype of political polarization in most if not all western democratic political systems. Differential political psychology strives to trace back increasingly polarized political convictions to differences on the individual level. Recent evolutionary informed approaches suggest that interindividual differences in political orientation reflect differences in group-mindedness and cooperativeness. Contrarily, the existence of meaningful associations between political orientation, personality traits, and interpersonal behavior has been questioned critically. Here, we shortly review evidence showing that these relationships do exist, which supports the assumption that political orientation is deeply rooted in the human condition. Potential reasons for the premature rejection of these relationships and directions for future research are outlined and implications for refinements and extensions of evolutionary informed approaches are derived.

We, Them, and It: Dictator Game Offers Depend on Hierarchical Social Status, Artificial Intelligence, and Social Dominance

We investigated the influence of social status on behavior in a modified dictator game (DG). Since the DG contains an inherent dominance gradient, we examined the relationship between dictator decisions and recipient status, which was operationalized by three social identities and an artificial intelligence (AI). Additionally, we examined the predictive value of social dominance orientation (SDO) on the behavior of dictators toward the different social and non-social hierarchical recipients. A multilevel model analysis showed that recipients with the same status as the dictator benefited the most and the artificial intelligence the least. Furthermore, SDO, regardless of social status, predicted behavior toward recipients in such a way that higher dominance was associated with lower dictator offers. In summary, participants treated other persons of higher and lower status equally, those of equal status better and, above all, an algorithm worst. The large proportion of female participants and the limited variance of SDO should be taken into account with regard to the results of individual differences in SDO.

The benefit of virtue signaling: Corporate sleight-of-hand positively influences consumers' judgments about "social license to operate"

When confronted with concerns or backlash as a result of their environmental or sustainability performance, companies may elect to address them head-on by directly correcting their real or perceived misdeeds. However, it is often the case that businesses are unwilling or unable to address their transgressions directly; in these cases, they may elect to draw attention to indirect substantiality benefits unfolding in areas unrelated to where the concerns or backlash initially arose. In this study, we sought to test the effect of these indirect and direct responses to sustainability challenges on two dependent variables: public perception of company reputation, and their willingness to grant a company "social license" for future business activities. Compared to a business-as-usual control condition, and across three company contexts, consumers provided favorable ratings of reputation, and were willing to grant social license, when companies responded indirectly to a sustainability challenge. These results highlight the powerful effect of indirect responses, which may be perceived as "greenwash", and the importance of intuitive judgmental heuristics and individual value orientations when consumers form impressions about corporate sustainability.

The dual evolutionary foundations of political ideology

Research over the last fifty years has suggested that political attitudes and values around the globe are shaped by two ideological dimensions, often referred to as economic and social conservatism. However, it remains unclear why this ideological structure exists. Here we highlight the striking concordance between these dual dimensions of ideology and independent convergent evidence for two key shifts in the evolution of human group living. First, humans began to cooperate more and across wider interdependent networks. Second, humans became more group-minded, conforming to social norms in culturally marked groups and punishing norm-violators. We propose that fitness trade-offs and behavioural plasticity have maintained functional variation in willingness to cooperate and conform within modern human groups, naturally giving rise to the two dimensions of political ideology. Supported by evidence from across the behavioural sciences, this evolutionary framework provides insight into the biological and cultural basis of political ideology.

Parochial Versus Universal Cooperation: Introducing a Novel Economic Game of Within- and Between-Group Interaction

Engaging in personally costly within-group cooperation benefits one’s in-group members but also impacts other groups by benefiting, neglecting, or harming out-group members, leading to a range of potential consequences for between-group relations (e.g., collaboration vs. competition). We introduce the Intergroup Parochial and Universal Cooperation (IPUC) game to investigate the prevalence of the individual preferences underlying these different expressions of within-group cooperation: universalism, weak parochialism, and strong parochialism. In two online experiments with natural groups, we show that the IPUC has value beyond existing economic games in measuring these preferences separately. In a third experiment conducted in the lab, we show how dispositional measures traditionally associated with within- and between-group cooperation, that is, social value orientation, social dominance orientation, honesty-humility, and empathic concern, predict different preferences. Thus, the IPUC provides a tool to better understand within- and between-group interactions and to test interventions to overcome intergroup conflict.
