Recent research and theorizing suggest that desires for group-based dominance underpin biases towards both human outgroups and (non-human) animals. A systematic study of the common ideological roots of human-human and human-animal biases is, however, lacking. Three studies (in Belgium, UK, and USA) tested the Social Dominance HumanAnimal Relations Model (SD-HARM) proposing that Social Dominance Orientation (SDO) is a key factor responsible for the significant positive association between ethnic outgroup attitudes and speciesist attitudes towards animals, even after accounting for other ideological variables (that possibly confound previous findings). Confirming our hypotheses, the results consistently demonstrated that SDO, more than right-wing authoritarianism (RWA), is a key factor connecting ethnic prejudice and speciesist attitudes. Furthermore, Studies 2 and 3 showed that both SDO and RWA are significantly related to perceived threat posed by vegetarianism (i.e., ideologies and diets minimizing harm to animals), but with SDO playing a focal role in explaining the positive association between threat perceptions and ethnic prejudice. Study 3 replicated this pattern, additionally including political conservatism in the model, itself a significant correlate of speciesism. Finally, a meta-analytic integration across studies provided robust support for SD-HARM and offers important insights into the psychological parallels between human intergroup and human-animal relations.
Belief in conspiracy theories is associated with negative outcomes such as political disengagement, prejudice, and environmental inaction. The current studies – one cross‐sectional (N = 253) and one experimental (N = 120) – tested the hypothesis that belief in conspiracy theories would increase intentions to engage in everyday crime. Study 1 demonstrated that belief in conspiracy theories predicted everyday crime behaviours when controlling for other known predictors of everyday crime (e.g., Honesty–Humility). Study 2 demonstrated that exposure to conspiracy theories (vs. control) increased intentions to engage in everyday crime in the future, through an increased feeling of anomie. The perception that others have conspired may therefore in some contexts lead to negative action rather than inaction.
Stronger beliefs in human supremacy over animals, and stronger perceived threat posed by vegetarianism to traditional practices, are associated with stronger speciesism and more meat consumption. Both variables might also be implicated in the moral exclusion of animals. We tested this potential in a 16‐month longitudinal study in the USA (N = 219). Human supremacy showed longitudinal effects on the moral exclusion of all animals. Vegetarianism threat only predicted moral exclusion of food animals (e.g., cows and pigs), and, unexpectedly, appealing wild animals (e.g., chimps and dolphins). These findings demonstrate the importance of both human supremacy and perceived threat in explaining moral exclusion of animals and highlight potential paradoxical negative consequences of the rise of vegetarianism.
Belief in conspiracy theories about societal events is widespread and has important consequences for political, health, and environmental behaviour. Little is known, however, about how conspiracy theorizing affects people's everyday working lives. In the present research, we predicted that belief in conspiracy theories about the workplace would be associated with increased turnover intentions. We further hypothesized that belief in these organizational conspiracy theories would predict decreased organizational commitment and job satisfaction. Finally, we hypothesized that these factors would mediate the relationship between organizational conspiracy theories and turnover intentions. In three studies (one correlational and two experiments, Ns = 209, 119, 202), we found support for these hypotheses. The current studies therefore demonstrate the potentially adverse consequences of conspiracy theorizing for the workplace. We argue that managers and employees should be careful not to dismiss conspiracy theorizing as harmless rumour or gossip.
The period following UK's European Union referendum in 2016 foreshadows significant social and political change in the UK. The current research draws on social psychological theories to empirically examine the drivers of voting decisions during the referendum. We report the results of a prospective study using structural equation modelling with data (N = 244) collected just before, and self‐reported voting behaviour immediately following (N = 197), the European Union referendum. We employ a person and social approach to examine the additive roles of worldview, conservatism, social identity, and intergroup threat as predictors of voting intentions and behaviour. Results showed that person factors (worldview and conservatism) predicted voting intentions through social factors (European identity and realistic threat) and that intentions predicted behaviour. The results highlight the importance of addressing threat‐based intergroup rhetoric and the potential of common in‐group identity to mitigate psychological threat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
