We are what ‘we’ eat
Navigating family dynamics in the transition to a plant-forward diet
While sustainable diets have predominantly been examined through the lens of individual decision-making, growing evidence underscores the critical role of relational dynamics in the adoption and maintenance of such practices. This study examined the role of relational climate (i.e. cohesion and flexibility) in governing how family units navigate dietary change. Eighty-four individuals who were pursuing a plant-forward diet participated in a 14-da…
Is being anti-vegan a distinct dietarian identity? An investigation with omnivores, vegans, and self-identified “anti-vegans”
Adding to research on the form and content of anti-vegan sentiment, recent scholarship has identified a group of individuals who self-subscribe as "anti-vegan". Here, we sought to determine whether anti-veganism might reflect a distinct dietarian identity with its own unique ideological profile. Two-hundred and fourteen vegans, 732 omnivores, and 222 self-identified "anti-vegans" were assessed using a survey methodology that included the Dietaria…
How bad is it to eat an intelligent chicken? Children's judgments of eating animals are less ‘self‐serving’ than adults
Research shows that adult meat eaters strategically distort or disregard information about animals (e.g., their intelligence) that is problematic for meat consumption. However, the development of such behaviours is not well understood. Two studies tested whether primary‐school‐age children exhibit motivated use of information about food animals as adults do ( N = 148 children, 410 adults). Using experimental methods that manipulated participants’…
How conflicted are farmers about meat? livestock farmers’ attachment to their animals and attitudes about meat
Livestock farmers depend on animal slaughter for their livelihood while also being responsible for their animals’ welfare. This study explored how farmers psychologically manage this ambivalent relationship with their animals. Seventy-two meat-eating livestock farmers participated, as well as 99 meat-eating and 103 meat-avoiding, non-farmer pet owners, living in the UK. Participants were assessed on their attachments to their pets and farmed anim…
An appetite for meat? Disentangling the influence of animal resemblance and familiarity
Unpalatable truths
Monitoring a meat-free pledge with smartphones
Pledges are a popular strategy to encourage meat reduction, though experimental studies of their efficacy are lacking. Three-hundred and twenty-five participants from three different countries (UK, Germany, Australia) were randomly assigned to pledge 28 days meat-free or not, and their behavior was tracked via smartphones. Participants answered daily surveys regarding their eating behavior, meat cravings, and shared photos of their meals. Baselin…
Against the cult of veganism’
Despite the established health and ecological benefits of a plant-based diet, the decision to eschew meat and other animal-derived food products remains controversial. So polarising is this topic that anti-vegan communities - groups of individuals who stand vehemently against veganism - have sprung up across the internet. Much scholarship on veganism characterizes anti-vegans in passing, painting them as ill-informed, uneducated, or simply obstin…
The role of meat appetite in willfully disregarding factory farming as a pandemic catalyst risk
Development and validation of the motivations to Eat Meat Inventory
Previous research suggests that there are four primary motives to eat meat: that it is natural, normal, necessary, or nice. However, these motives have not yet been distinguished empirically; the lack of a measurement tool that can distinguish these motives has contributed to a literature that focuses primarily on meat-eating motivation or justification in general, as opposed to differences between these motives. We developed a 19-item measure, t…
Consumer perceptions of conventional and alternative protein sources
From Pets to Pests
Positive relationships with pets can sometimes foster more positive judgments of other animals. The present study sought to examine the scope of this “pets as ambassadors” effect in relation to four meaningful animal categories (companion, farmed, predator, and pest) derived from the Animal Images Database (Animal.ID). The Animal.ID contains ratings from 376 Portuguese individuals on pet attachment and several dimensions related to animal attribu…
Butchers’ and deli workers’ psychological adaptation to meat
In many societies today, the average consumer is largely removed from the earlier stages of meat production wherein meat, in many ways, resembles an animal. The present study examined the emotional and psychological consequences of recurrent meat handling. Fifty-six individuals with commercial experience handling meat (butchers and deli workers) were contrasted with 103 individuals without such experience. Participants were presented images of me…
Reevaluating Moral Disgust
Disgust-sensitive individuals are particularly morally critical. Some theorists take this as evidence that disgust has a uniquely moral form: disgust contributes to moralization even of pathogen-free violations, and disgust’s contribution to moralization is unique from other emotional states. We argue that the relationship between disgust sensitivity (DS) and moral judgment is not special in two respects. First, trait sensitivity to many other af…
Which Appraisals Are Foundational to Moral Judgment? Harm, Injustice, and Beyond
Harm-centric accounts of judgments of moral wrongdoing argue that moral judgments are fundamentally based on appraisals of harm. However, past research has failed to operationally discriminate harm appraisals from appraisals related to injustice. Four studies carefully discriminated harm qua pain/suffering from injustice, alongside appraisals related to impurity, authority, and disloyalty. Appraisals of injustice outperformed appraisals of harm a…
Are Baby Animals Less Appetizing? Tenderness toward Baby Animals and Appetite for Meat
Three studies investigated whether thoughts and feelings generated by baby animals might oppose appetite for meat. A prestudy established babyness as an important factor predicting moral concern for farmed animals. Study 1 showed that presenting images of baby animals, versus adult animals, as the source of meat reduced appetite for meat, but this effect was weak and found exclusively among women. Study 2 replicated and extended study 1 using a l…
When It’s Bad to Be Friendly and Smart
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 wo…
When Meat Gets Personal, Animals’ Minds Matter Less
Why are many Westerners outraged by dog meat, but comfortable with pork? This is particularly puzzling, given strong evidence that both species are highly intelligent. We suggest that although people consider intelligence a key factor in determining animals’ moral status, they disregard this information when it is self-relevant. In Study 1, we show that intelligence plays a major role in the moral concern afforded to animals in the abstract. In S…

Rationalizing meat consumption. The 4Ns
Religiosity, Political Orientation, and Consequentialist Moral Thinking
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…
Further challenges to the “authentic”/“hubristic” model of pride
The Authentic and Hubristic Pride Scales (AHPS) are the methodological core of an influential perspective on pride. The Authentic Pride (AP) scale purportedly measures a distinct facet of pride rooted in attributing success to effort (but not ability), and related to prestige (but not dominance). The Hubristic Pride (HP) scale purportedly measures a complementary facet rooted in attributing success to ability (but not effort), and related to domi…
CAD Revisited
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 a…
Conceptual and empirical challenges to the “authentic” versus “hubristic” model of pride
An increasingly influential perspective in the study of pride holds that there are two distinct facets characterized by distinct ways of appraising the causes of achievement. "Authentic Pride" has been characterized as attributing success to one's temporary effort, whereas "Hubristic Pride" purportedly attributes success to one's stable, innate ability. In Studies 1a and 1b, perceptions of not genuinely meriting credit for successes significantly…
Moral character predominates in person perception and evaluation
What sorts of trait information do people most care about when forming impressions of others? Recent research in social cognition suggests that "warmth," broadly construed, should be of prime importance in impression formation. Yet, some prior research suggests that information about others' specifically moral traits--their moral "character"--may be a primary dimension. Although warmth and character have sometimes been conceived of as interchange…

If You Love Me Keep My Commandments”
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 prefe…
