Vegetarianism and veganism are increasingly prevalent in Western countries, yet anecdotal expressions of negativity toward vegetarians and vegans are common. We empirically tested whether bias exists toward vegetarians and vegans. In Study 1 omnivores evaluated vegetarians and vegans equivalently or more negatively than several common prejudice target groups (e.g., Blacks). Bias was heightened among those higher in right-wing ideologies, explained by heightened perceptions of vegetarian/vegan threat. Vegans (vs. vegetarians) and male (vs. female) vegetarians/vegans were evaluated more negatively overall. In Study 2 omnivores evaluated vegetarians and vegans more negatively than several nutritional outgroups (e.g., gluten intolerants) and evaluated vegan/vegetarians motivated by animal rights or environmental concerns (vs. health) especially negatively. In Study 3, vegetarians and especially vegans reported experiencing negativity stemming from their diets. Empirically documenting antivegetarian/vegan bias adds to a growing literature finding bias toward benign yet social norm-challenging others.
