In the target article, we presented the hypothesis that parasite-stress variation was a causal factor in the variation of in-group assortative sociality, cross-nationally and across the United States, which we indexed with variables that measured different aspects of the strength of family ties and religiosity. We presented evidence supportive of our hypothesis in the form of analyses that controlled for variation in freedom, wealth resources, and wealth inequality across nations and the states of the USA. Here, we respond to criticisms (...) from commentators and attempt to clarify and expand the parasite-stress theory of sociality used to fuel our research presented in the target article. (shrink)

Recently, many critics have argued that disgust is a morally harmful emotion, and that it should play no role in our moral and legal reasoning. Here we defend disgust as a morally beneficial moral capacity. We believe that a variety of liberal norms have been inappropriately imported into both moral psychology and ethical studies of disgust: disgust has been associated with conservative authors, values, value systems, and modes of moral reasoning that are seen as inferior to the values and moral (...) emotions that are endorsed by liberal critics. Here we argue that the meta-ethical assumptions employed by the critics of disgust are highly contentious and in some cases culture bound. Given this, we should avoid adopting simplified meta-ethical positions in experimental moral psychology, as these can skew the design and interpretation of experiments, and blind us to the potential value of moral disgust harnessed in the service of liberal ends.

Vaccine refusers often seem motivated by disgust, and they invoke ideas of purity, contamination and sanctity. Unfortunately, the emotion of disgust and its companion ideas are not directly responsive to the probabilistic and statistical evidence of research science. It follows that increased efforts to promulgate the results of vaccine science are not likely to contribute to increased rates of vaccination among persons who refuse vaccines because of the ‘ethics of sanctity’. Furthermore, the fact that disgust-based vaccine refusal is not monolithic (...) – vaccine refusers manifest disgust at different objects and invoke different ideas about purity and contamination – further complicates public health efforts to increase vaccination rates.

Contemporary moral psychology has focused on the notion of a universal moral sense, robust to individual and cultural differences. Yet recent evidence has revealed individual differences in the psychological processes for moral judgment: controlled cognition, mental-state reasoning, and emotional responding. We discuss this evidence and its relation to cross-cultural diversity in morality.

Moral foundations research suggests that liberals care about moral values related to individual rights such as harm and fairness, while conservatives care about those foundations in addition to caring more about group rights such as loyalty, authority, and purity. However, the question remains about how conservatives and liberals differ in relation to group-level moral principles. We used two versions of the moral foundations questionnaire with the target group being either abstract or specific ingroups or outgroups. Across three studies, we observed (...) that liberals showed more endorsement of Individualizing foundations with an outgroup target, while conservatives showed more endorsement of Binding foundations with an ingroup target. This general pattern was found when the framed, target-group was abstract and when target groups were specified about a general British-ingroup and an immigrant-outgroup. In Studies 2 and 3, both Individualizing-Ingroup Preference and Binding-Ingroup Preference scores predicted more Attitude Bias and more Negative Attitude Bias toward immigrants, more Implicit Bias, and more Perceived Threat from immigrants. We also demonstrated that increasing liberalism was associated with less Attitude Bias and less Negative Bias toward immigrants, less Implicit Bias, and less Perceived Threat from immigrants. Outgroup-individualizing foundations and Ingroup-Binding foundations showed different patterns of mediation of these effects. (shrink)

Legal ethics theories give competing and exclusive accounts of the ethical foundations of the lawyer’s role. They disagree about the relationship between morality and law, about the content of the lawyer’s central ethical duties and about how specific ethical problems should be resolved. Each theoretical account asserts that the others are mistaken in some fundamental way. Yet all legal ethics theories are theories of action; legal ethics theorists do not seek merely to enlighten, they also seek to influence how lawyers (...) and the legal profession respond to ethical issues. This creates a problem of disagreement: the problem created by the divergent but exclusive claims made by different ethical theories at the point when those theories are to be translated into action. This paper considers how, given the problem of disagreement, legal ethics theories can have any impact on individual ethical decision-making or public policy. Specifically, it considers how theories can have any impact given a) that they fundamentally disagree; and b) what experimental psychology tells us about how people make ethical decisions in fact, and the nature of lawyer regulation.

Despite burgeoning interest in employee silence, there are still significant gaps in our understanding of (a) the antecedents of employee silence in organizations and (b) the implications of engaging in silence for employees. Using two experimental studies (Study 1a, N = 91; Study 1b, N = 152) and a field survey of full-time working adults (Study 2, N = 308), we examined overall justice as an antecedent of acquiescent (i.e., silence motivated by futility) and quiescent silence (i.e., silence motivated by (...) fear of sanctions). Across the studies, results indicated that overall justice is a significant predictor of both types of silence in organizations. Furthermore, Study 2 indicated that the implications of silence extend beyond the restriction of information flow in organizations to include employee outcomes. Specifically, acquiescent silence partially or fully mediated the relationship between overall justice perceptions and emotional exhaustion, psychological withdrawal, physical withdrawal, and performance. Quiescent silence partially mediated these relationships, with the exception of performance. The theoretical and practical implications of these findings for both the justice and silence literatures are discussed. (shrink)

Food has become a prominent object of everyday moral discussions. This study examines how gender, political orientation, and country of origin are connected to moral foundation endorsement in food-related moral thinking. Respondents were university students (N = 371) from Finland, Denmark, and Italy who completed a word association task, in that given stimulus words were “ethical food” and “unethical food.” Results showed a presence of five moral foundations in the data, and indicated high prevalence of the Purity/Sanctity foundation in food-related (...) moral thinking. As expected, gender differences emerged in the endorsement of the Fairness/Reciprocity and the Purity/Sanctity foundations. Also, between-country differences emerged in four of the five moral foundations, indicating that even within Europe countries may differ from each other in their endorsement of foundations. The results also verified the previously found effect of political orientation in three of the five moral foundations, although the study used a completely new and different type of method compared with previous studies. The study concludes by proposing more cross-national comparative studies where the focus is on the specific objects of moral thinking. (shrink)

Outside Western, predominantly secular‐liberal environments, norms restricting bodily and sexual conduct are widespread. Moralization in the so‐called purity domain has been treated as evidence that some putative violations are victimless. However, respondents themselves disagree: They often report that private yet indecent acts incur self‐harm, or harm to one's family and the wider community—a result which we replicate in Study 1. We then distinguish two cognitive processes that could generate a link between harmfulness and immorality, and recreate them in Studies 2 (...) and 3: Colombian and British participants were randomly assigned to either reflect (decide whether acts are harmful and reconsider their initial moral judgments) or rationalize (decide whether acts are immoral and reconsider their initial harmfulness beliefs). In both countries, reflection promoted opposition to unjust, but not impure, behavior. Additionally, in both countries, ruminating on the moral status of impure acts elevated beliefs in the acts' harmfulness. We conclude by suggesting that rationalization aggravates, while reflection mitigates, intergroup disagreement regarding putative violations of purity and decency. (shrink)
