    Abstract:
    In studies conducted in the US and Poland, vegans, non-vegan vegetarians, pescatarians, and omnivores described how they perceived they were treated by others as a function of their diet. We found that vegans thought that others treated them more negatively because of their diets than vegetarians or pescatarians did, and pescatarians thought that others treated them less negatively than vegans and vegetarians did. In Study 1 (N = 96), we found that vegans, vegetarians, and pescatarians thought that others treated them more negatively because of their diet than omnivores did. Moreover, perceptions of negative treatment were positively related to how much participants' diets differed from an omnivorous diet. We replicated these findings in Study 2 (N = 1744), and we also found that vegans, vegetarians, and pescatarians thought that others treated them more positively in some ways compared to omnivores. In Study 3 (N = 1322), we found that differences in perceptions of negative treatment by strangers among vegans, vegetarians, and pescatarians were larger than differences in perceptions of treatment by friends and family members.
