A way forward? The impact of interculturalism on intergroup relations in culturally diverse nations

Abstract

Various diversity ideologies including assimilation, colorblindness, and multiculturalism have been promoted with mixed results about their costs and benefits. In the current research, we consider the impact of a new diversity ideology, interculturalism, discussed and debated by political philosophers and policy-makers as the “way forward.” Across three experiments (N = 1230) in two ethnically diverse nations, we examined the causal impact of promoting interculturalism on intergroup relations. Data revealed that interculturalism reduced outgroup prejudice, increased willingness to engage in intergroup contact, improved implicit attitudes, and increased behavioral trust and cooperation relative to controls. Reductions in essentialist beliefs partially mediated the impact of interculturalism, highlighting one psychological mechanism underlying the benefits of interculturalism. However, interculturalism was found to be no better than multiculturalism in its impact on intergroup relations in two of three experiments. Collectively, these studies suggest that interculturalism may be a promising new diversity strategy for improving intergroup relations.
