نقش انزجار میان گروهی در پیش بینی ارزیابی های منفی نسبت به برون گروه

We introduce intergroup disgust as an individual difference and contextual manipulation. As an individual difference, intergroup disgust sensitivity (ITG-DS) represents affect-laden revulsion toward social outgroups, incorporating beliefs in stigma transfer and social superiority. Study 1 (5 samples, N = 708) validates the ITG-DS scale. Higher ITG-DS scorers demonstrated greater general disgust sensitivity, disease concerns, authoritarian/conservative ideologies, and negative affect. Greater ITG-DS correlated with stronger outgroup threat perceptions and discrimination, and uniquely predicted negative outgroup attitudes beyond well-established prejudice-predictors. Intergroup disgust was experimentally manipulated in Study 2, exposing participants (n = 164) to a travel blog concerning contact with a disgust-evoking (vs. neutral) outgroup. Manipulated disgust generated negative outgroup evaluations through greater threat and anxiety. This mediation effect was moderated: Those higher (vs. lower) in ITG-DS did not experience stronger disgust, threat, or anxiety reactions, but demonstrated stronger translation of aversive reactions (especially outgroup threat) into negative attitudes. Theory development and treatment implications are considered.► Introduce intergroup disgust concept (repulsion toward social outgroups). ► Develop individual difference measure and establish reliability and validity. ► Manipulate group-relevant disgust, determine causal effects, mediators, moderators. ► Intergroup disgust sensitivity moderates disgust reaction-to-attitudes effect.
