Recent theorizing suggests that the 4Ns - that is, the belief that eating meat is natural, normal, necessary, and nice - are common rationalizations people use to defend their choice of eating meat. However, such theorizing has yet to be subjected to empirical testing. Six studies were conducted on the 4Ns. Studies 1a and 1b demonstrated that the 4N classification captures the vast majority (83%-91%) of justifications people naturally offer in defense of eating meat. In Study 2, individuals who endorsed the 4Ns tended also to objectify (dementalize) animals and included fewer animals in their circle of moral concern, and this was true independent of social dominance orientation. Subsequent studies (Studies 3-5) showed that individuals who endorsed the 4Ns tend not to be motivated by ethical concerns when making food choices, are less involved in animal-welfare advocacy, less driven to restrict animal products from their diet, less proud of their animal-product decisions, tend to endorse Speciesist attitudes, tend to consume meat and animal products more frequently, and are highly committed to eating meat. Furthermore, omnivores who strongly endorsed the 4Ns tended to experience less guilt about their animal-product decisions, highlighting the guilt-alleviating function of the 4Ns.

An evolutionary psychological perspective has much to offer the study of Internet behavior. However, cyber-psychologists have hitherto neglected this rich theoretical tradition and evolutionary psychologists have been slow to apply their perspective to computer-mediated behavior. This paper applies an evolutionary perspective to the study of Internet behavior in four relevant domains: (1) mating and sexual competition, (2) parenting and kinship, (3) trust and social exchange, and (4) personal information management. Both general and specific evolutionary theories are explored in relation to online behavior in each domain, with an emphasis on generating testable hypotheses for future research.

Three studies demonstrated that the moral judgments of religious individuals and political conservatives are highly insensitive to consequentialist (i.e., outcome-based) considerations. In Study 1, both religiosity and political conservatism predicted a resistance toward consequentialist thinking concerning a range of transgressive acts, independent of other relevant dispositional factors (e.g., disgust sensitivity). Study 2 ruled out differences in welfare sensitivity as an explanation for these findings. In Study 3, religiosity and political conservatism predicted a commitment to judging “harmless” taboo violations morally impermissible, rather than discretionary, despite the lack of negative consequences rising from the act. Furthermore, non-consequentialist thinking style was shown to mediate the relationship religiosity/conservatism had with impermissibility judgments, while intuitive thinking style did not. These data provide further evidence for the influence of religious and political commitments in motivating divergent moral judgments, while highlighting a new dispositional factor, non-consequentialist thinking style, as a mediator of these effects.

Previous studies investigating altruistic punishment have confounded the effects of two independent variables: information transmission (or breach of privacy) and personal identification (or breach of anonymity). Here we report findings from a brief study in which participants were asked to respond to a social norm violation (i.e., an anonymous actor had behaved selfishly in an economic game) by deciding whether to sacrifice their own endowment to punish this person. A third of the participants were told that their economic decisions would be made known to another player but could not be identified (privacy breach condition), whereas another third were informed that their decision as well as their names would be made known (anonymity breach condition). (The decisions of control participants were completely anonymous and private.) Participants also justified their economic decisions and reported their emotional experiences. The results were participants punished most in the privacy and anonymity breach conditions and least in the control condition. These findings have implications for existing evolutionary accounts of altruistic punishment.

The CAD model posits a mapping of contempt, anger, and disgust onto the moral codes of community, autonomy, and divinity, respectively. A recent study by Hutcherson and Gross posited moral disgust as the dominant other-condemning emotion across all three moral codes. However, the methodology used may have incidentally increased the relevance of disgust. In the current experiment, one condition repeated Hutcherson and Gross’s procedure, while in another condition, the authors added the word moral to three other emotions. Consistent with CAD, anger had the highest intensity ratings in response to autonomy violations, whereas “grossed out” was the dominant response to divinity violations. Furthermore, the adjective “moral” increased the relevance of anger, contempt, and fear in irrelevant domains, which suggests that the adjective moral increases any emotion’s moral relevance.

Morality, sociability, and competence are distinct dimensions in person perception. We argue that a person’s morality informs us about their likely intentions, whereas their competence and sociability inform us about the likelihood that they will fulfill those intentions. Accordingly, we hypothesized that whereas morality would be considered unconditionally positive, sociability and competence would be highly positive only in moral others, and would be less positive in immoral others. Using exploratory factor analyses, Studies 1a and 1b distinguished evaluations of morality and sociability. Studies 2 to 5 then showed that sociability and competence are evaluated positively contingent on morality—Study 2 demonstrated this phenomenon, while the remaining studies explained it (Study 3), generalized it (Studies 3-5), and ruled out an alternative explanation for it (Study 5). Study 6 showed that the positivity of morality traits is independent of other morality traits. These results support a functionalist account of these dimensions of person perception.

Anger may be more responsive than disgust to mitigating circumstances in judgements of wrongdoing. We tested this hypothesis in two studies where we had participants envision circumstances that could serve to mitigate an otherwise wrongful act. In Study 1, participants provided moral judgements, and ratings of anger and disgust, to a number of transgressions involving either harm or bodily purity. They were then asked to imagine and report whether there might be any circumstances that would make it all right to perform the act. Across transgression type, and controlling for covariance between anger and disgust, levels of anger were found to negatively predict the envisioning of mitigating circumstances for wrongdoing, while disgust was unrelated. Study 2 replicated and extended these findings to less serious transgressions, using a continuous measure of mitigating circumstances, and demonstrated the impact of anger independent of deontological commitments. These findings highlight the differential relationship that anger and disgust have with the ability to envision mitigating factors.

Two experiments demonstrated that religiosity affects the way people resolve moral dilemmas. Participants were presented a series of immoral actions and were asked to justify the wrongness of the action by appealing to either the violation of a rule (rule-based argument) or the negative consequences resulting from the action (outcome-based argument). In Study 1, it was shown both among British and American samples that religious individuals preferred rule-based moral arguments to consequentialist moral arguments more than nonreligious individuals, and covariance with political conservatism did not account for this effect. Study 2 replicated these results with revisions to the materials and extended measures. In this study, dimensions of religiosity—particularly Christian Orthodoxy—predicted rule-based morality independent of a personal need for structure, need for cognition, and right-wing authoritarianism. These results imply that religious individuals who are committed to orthodox religious teaching display a deontological style of morality for reasons that extend beyond a need for structure, cognitive simplicity, or submission to authority.

Religions have come to be intimately tied to morality and much recent research has shown that theists and nontheists differ in their moral behavior and decision making along several dimensions. Here we discuss how these empirical trends can be explained by fundamental differences in group commitment, motivations for prosociality, cognitive styles, and meta-ethics. We conclude by elucidating key areas of moral congruence.

Three studies tested the conditions under which people judge utilitarian harm to be authority dependent (i.e., whether its right or wrongness depends on the ruling of an authority). In Study 1, participants judged the right or wrongness of physical abuse when used as an interrogation method anticipated to yield useful information for preventing future terrorist attacks. The ruling of the military authority towards the harm was manipulated (prohibited vs. prescribed) and found to significantly influence judgments of the right or wrongness of inflicting harm. Study 2 established a boundary condition with regards to the influence of authority, which was eliminated when the utility of the harm was definitely obtained rather than forecasted. Finally, Study 3 replicated the findings of Studies 1-2 in a completely different context-an expert committees ruling about the harming of chimpanzees for biomedical research. These results are discussed as they inform ongoing debates regarding the role of authority in moderating judgments of complex and simple harm.
