Comparing the morally relevant capacities (e.g., intelligence, emotional capacities) of an animal that is frequently eaten by Americans (pig) & one that is not (dog) shifted participants’ moral beliefs about eating meat

Abstract: Coherence-based interventions can change people’s moral beliefs about abstract moral principles, but it is unclear whether these interventions would be similarly effective for everyday moral beliefs that can impact routine behavior. In the present research, we examined whether coherence-based “memes” highlighting the moral similarities of pigs and dogs can likewise shift moral beliefs about consuming meat. Across three experiments, we found beliefs about the permissibility of eating some animals can be subtly shifted by brief coherence-based interventions which highlight moral similarity. Comparing the morally relevant capacities (e.g., intelligence, emotional capacities) of an animal that is frequently eaten by Americans (pig) and an animal that is typically considered forbidden to eat by Americans (dog) shifted participants’ moral beliefs. We discuss the implications of these findings for psychological and ethical theory.
