The climate and ecological crisis poses an unprecedented challenge, with scientists playing a critical role in how society understands and responds. This study examined how 27 environmentally concerned scientists from 11 countries construct the future in the context of climate change, applying a critical discursive psychology analysis. The degree to which the future is constructed as predetermined or transformable impacts both the urgency and scope of proposed actions.

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 Dietarian Identity Questionnaire and ideological markers related to dark humour, social dominance orientation (SDO), speciesism, male-role norms, moral relativism, and attitudes toward science.

Many children care about animals yet are accepting of meat consumption. This may reflect a disconnect between children's meat eating, food-systems knowledge, and their moral evaluations. A theoretical framework is proposed for understanding the developmental trajectory of this disconnection.

Plant-forward diets offer a potential solution to many of the health and ecological crises that we find ourselves facing today. A key barrier to the adoption and maintenance of plant-forward diets is an anticipated lack of support from family members, friends and romantic partners. The present study examined how relational climate (i.

There is much disagreement about the claim that impurity constitutes a moral domain. We propose a set of minimal criteria that could help re-orient the field to a direction of consensus in the assessment of this claim. We illustrate how the criteria apply to aspects of the current literature.

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 obstinate.

Animal minds are of central importance to debates about their rights and welfare. Remaining ignorant of evidence that animals have minds is therefore likely to facilitate their mistreatment. Studying samples of adults and students from the UK and US we found that, consistent with motivational perspectives on meat consumption, those who were more (vs.

Consumers in modern society are often less exposed to meat that resembles the animal, and thus are less familiar with it, making it difficult to disentangle the influence of these two inputs (familiarity vs. animal resemblance) on meat appetite. Across three studies, we sought to systematically disentangle the impact of familiarity and animal resemblance on meat appetite using inductive (Study 1) and experimental (Studies 2a-2b) approaches.

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.

It is controversial whether ordinary people regard beliefs about the wrongness of harmful actions as objectively correct. Our deflationary hypothesis, consistent with much of the evidence, is that people are objectivists about harmful actions : when two parties disagree about whether such an action is wrong, people think that only one party is correct (the party believing that the action is wrong). However, Sarkissian and colleagues claimed that this evidence is misleading, showing that when the two disagreeing parties are from radically different cultures or species, people tend to think that both parties are correct (a non-objectivist position).

The current study modeled the attributions underlying moral concern for animals during childhood and adulthood with the aim of better understanding how concern for animals develops. In total, 241 children aged 6-10 years and 152 adults appraised a range of animals on seven appraisal dimensions and, subsequently rank-ordered which animals they would save in a medicine allocation task. Structural equation modeling revealed several developmental continuities and discontinuities in the dimensions children and adults used to evaluate animal lives.

Most infectious diseases are zoonotic, "jumping" from animals to humans, with COVID-19 no exception. Although many zoonotic transmissions occur on industrial-scale factory farms, public discussions mainly blame wild animal ("wet") markets or focus on reactionary solutions, posing a psychological obstacle to preventing future pandemics. In two pre-registered studies early in the 2020 pandemic, we examined whether British adults fail to recognize factory farming in causing epidemics, and whether such dismissal represents motivated cognition.

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, the Motivations to Eat Meat Inventory (MEMI), that fit a four-factor model in three samples (total N = 2175), including one with a large number of vegetarians.

Understanding consumer perceptions of meat alternatives is key to facilitating a shift toward more sustainable food consumption. Importantly, these perceptions may vary according to the characteristics of the consumer (e.g.

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.

There has been increasing interest in the study of human-animal relations. This contrasts with the lack of normative resources and materials for research purposes. We present subjective norms for a set of 120 open-source colour images of animals spanning a total of 12 biological categories (e.

Theories that view emotions as being related in some way to moral judgments suggest that condemning moral emotions should, at a minimum, be understood by laypeople to coincide with judgments of moral disapproval. Seven studies (total  = 826) tested the extent to which anger and disgust align with this criterion. We observed that while anger is understood to be strongly related to moral disapproval of people's actions and character, disgust is not (Studies 1a, 1b, 2a, 2b, and 3), and that, in contexts where disgust expressions are thought to coincide somewhat with moral disapproval, part of the reason is that the expression is perceived as anger (Study 4).

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.

It is clear that harmful agents are targets of severe condemnation, but it is much less clear how perceivers conceptualize the agency of harmful agents. The current studies tested two competing predictions made by moral typecasting theory and the dehumanization literature. Across six studies, harmful agents were perceived to possess less agency than neutral (non-offending) and benevolent agents, consistent with a dehumanization perspective but inconsistent with the assumptions of moral typecasting theory.

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.

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.

Anger and disgust may have distinct roles in sexual morality; here, we tested hypotheses regarding the distinct foci, appraisals, and motivations of anger and disgust within the context of sexual offenses. We conducted four experiments in which we manipulated whether mutual consent (Studies 1-3) or desire (Study 4) was present or absent within a counter-normative sexual act. We found that anger is focused on the injustice of non-consensual sexual acts, and the transgressor of the injustice (Studies 1 and 3).
