Socially mobile minority members (i.e., those who acquire a higher status membership) adjust their social identities, and eventually show negative attitudes towards minorities, as compared to non-mobile members. We examined whether these changes could be understood as the result of individual mobility achievements, or if they already occur at an earlier stage of the mobility process, when individuals are motivated and thus psychologically anticipate achieving mobility. In two studies, we looked at Portuguese immigrants in Switzerland (Ns = 180 and 241) at three mobility stages, that is, (1) Swiss naturalized Portuguese immigrants (socially mobile), (2) non-naturalized Portuguese who strongly wished to be naturalized (high anticipators), and (3) those who wished it less (low anticipators). First, we hypothesized a progressive assimilation to (distancing from) the Swiss (Portuguese) identity and culture (from the low anticipators to the high anticipators to the mobile). As expected, increasing levels of individual mobility were associated with stronger identification with Swiss identity and adoption of the Swiss culture. Conversely, increasing levels of individual mobility were associated with gradual distancing from the Portuguese culture, but against expectations, not with disidentification from the Portuguese identity. Second, we investigated how individual mobility stages were associated with a progressive deterioration of inter-minority relations. Results showed that increasing levels of individual mobility were not associated with more negative attitudes toward immigration (Study 1) but with less collective action intentions (Study 2). We discuss the consequences of anticipated and achieved individual mobility on asymmetric intergroup relations and support for social change.
