Why might some meat-eaters and meat-avoiders express negative attitudes toward each other? We investigated intergroup attitudes and potential underpinnings of these attitudes across three different dietary groups—veg*ans (vegetarians and vegans), flexitarians (people who restrict their meat intake partially), and meat-eaters—in Turkey (NStudy 1 = 366; NStudy 2 = 450). In both studies, veg*ans showed the greatest ingroup favouritism and reported the highest ingroup identification and perceived discrimination. Meat enjoyment, moral consideration, and perceived veg*an threat (among meat-eaters) predicted dietary ingroup identification in Study 1, whereas perceived discrimination towards one’s dietary group was the strongest predictor of identification among all dietary groups in Study 2. Among meat-avoiders, but not among meat-eaters, stronger dietary ingroup identification was associated with more negative outgroup attitudes. Findings are discussed in light of social identity theories and intergroup perspectives.
