Multilingualism and Out

In this research, we systematically study multilingualism as a predictor of acceptance of ethnic out-groups. It is argued that people who speak more languages are more cognitively flexible, that is, they have an enhanced flexibility in understanding and representing information. Higher cognitive flexibility is in turn expected to be related to higher deprovincialization: a reevaluation of one’s ethnocentric worldview. Deprovincialization is then expected to result in more openness toward ethnic out-groups, evidenced by a more inclusive notion of the national identity and reduced out-group dislike. Cross-sectional survey data among a representative sample of native Dutch participants from the Netherlands (N = 792) provide convincing support for these hypotheses and show that multilingualism is an important yet understudied factor in social–psychological research on prejudice reduction
