The article is devoted to the problem of discrimination of immigrants in the socioeconomic domain, which can be considered the main obstacle by the host society for the socio-economic adaptation of immigrants. Contrasting three reputed approaches to the study of prejudice and discrimination, and exploring for groups of mainstream population with similar acculturation characteristics (acculturation profiles), using the sample of 576 Russians non-immigrants, the relationship between social worldview (dangerous worldview and competitive worldview), ideological attitudes (right-wing authoritarianism, social dominance orientation, multicultural ideology) and willingness for intergroup contact was examined. The hypothesis of moderation by the acculturation profile (bicultural, alternate-bicultural, and assimilated) to the considered relationships was not supported, the proposed conceptual model across all groups was same. In general, the results showed that representations of individuals about the social world as a dangerous and competitive place, which is formed by individual differences originating from the personal experience of socialization and impact of the existing social environment, may also be associated with the support of multicultural ideology and willingness for intergroup contact that in turn to some extent influence the endorsement of discrimination of immigrants in the socioeconomic domain.
