Together to Welcome, Together to Exclude

This preregistered study examined whether positive and negative intergroup contact with migrants relates to collective action supporting and opposingmigrants as well as to interpersonal exclusion toward them via the key processes identified in the Social Identity Model of Collective Action. Structural equation models conducted on cross-sectional data from 506 Italian and English participants showed that positive (negative) contact related to higher (lower) collective inclusion and lower (higher) collective and interpersonal exclusion of migrants via group anger, identification, and efficacy. Considering positive and negative contact, collective action pro and againstmigrants and interpersonal behaviors simultaneously, this study provided a nuanced picture of the antecedents and processes underlying the advantaged group members’ behaviors toward migrants.
