Veg*ns’ and omnivores’ reciprocal attitudes and dehumanization: The role of social dominance orientation, ingroup identification, and anticipated reproach

Two studies compared omnivores’ and veg*ns’ attitudes and dehumanization tendencies toward each other and identified the social psychological factors explaining them. Study 1 (N = 208, Italians) showed that veg*ns’ hold less positive attitudes toward omnivores than the reverse, and attributed to them less human uniqueness and nature; these differences were explained by veg*ns’ stronger identification with the ingroup and higher perceptions of reproach from the outgroup, even if omnivores’ higher levels of social dominance orientation worsened their attitude toward veg*ns. Study 2 (preregistered, N = 200, mostly from UK) overall replicated Study 1 findings at the explicit level. Interestingly, omnivores’ and veg*ns’ implicit attitudes were equally positive (but less positive than self-reported attitudes) and not predicted by the same mediators associated with the explicit measures. This work suggests that neither veg*ns nor omnivores hold negative attitudes toward each other: they were both positive or neutral toward the outgroup, even if at the explicit level this positivity is greater for omnivores.
