Interculturalism: A new diversity ideology with interrelated components of dialogue, unity, and identity flexibility

Increased cultural diversity has led to considerable debate on how to best promote intergroup harmony within pluralistic nations. In the current research, we consider the nature of interculturalism, a new diversity ideology extensively discussed by political philosophers and policy‐makers in Europe and beyond. Interculturalism consists of three interrelated components of dialogue, unity, and identity flexibility. Using data (N = 2,364) from three national surveys in two ethnically diverse nations (Netherlands and USA), we test a new measure of interculturalism and establish its independence from multiculturalism and assimilation. We then demonstrate that interculturalism predicts positive intergroup outcomes, over and above multiculturalism, and is in a theoretically meaningful way related to various criterion measures. Collectively, these studies establish the uniqueness of interculturalism from multiculturalism and demonstrate its promise for improving intergroup relations in culturally diverse nations.
