Domestic or Wild, Edible or Friend? Empathy, Speciesism, and the Psychological Boundaries of Moral Concern for Animals

Human relationships with animals are marked by striking inconsistencies: while some animals are cherished as companions, others are consumed as food. In this pre-registered study, we investigated how empathy, speciesism, and animal categorization (domestication, edibility) jointly shape emotional and moral responses to animal suffering. Two hundred and sixty-seven participants took part in this study, each exposed to six vignettes depicting harm inflicted on animals systematically varied by domestication (domestic vs. wild) and edibility (edible, mixed, non-edible). Participants completed the Interpersonal Reactivity Index (IRI; trait empathy) and the Caviola Speciesism Scale. State empathy and related emotions (anger toward humans, justification of harm, concern for animals, perceived suffering) were measured after each vignette. Linear mixed-effects models tested the influence of animal categories and individual differences. Domesticated animals evoked more empathy than wild animals. Trait empathy predicted stronger empathy, while speciesism predicted weaker empathy and less moral condemnation. Trait empathy especially predicted empathic responses among participants low in speciesism. Edibility effects were less pronounced but aligned with expectations: food animals evoked weaker moral concern. Women and younger participants reported higher empathy overall. The “meat paradox” highlights the psychological mechanisms behind empathy and speciesism, showing inconsistent moral concern across categories. Interventions like humanizing farmed animals and challenging speciesist ideologies can broaden the moral circle and support animal welfare. This study highlights the impact of human–animal relations on ethics, diets, and public policy.
