Globalization brings new cultural experiences and choices. Not only can people choose musical, culinary, and literary activities from other cultures, but they also can choose experiences that mix cultures together. We propose that preference for culturally mixed experiences hinges on preconceptions about cultural differences, or "diversity ideologies," namely colorblindness, multiculturalism, and polyculturalism. In Study 1, we measured participants' endorsement of these three diversity ideologies and their preferences for culturally unitary versus mixed experiences. Results showed that polyculturalism (the mindset that cultures interact and contribute to each other) was positively associated with liking of culturally mixed experiences. In Study 2, we experimentally induced these three mindsets and found that the polycultural mindset heightened preferences for culturally mixed experiences. In Study 3, we replicated the positive effect of polyculturalism on preference for cultural mixes but not other kinds of mixes. Further, the effect of polyculturalism on people's choice of cultural mixes was mediated by purity concerns. We discuss implications for the psychology of globalization. (C) 2016 Elsevier Inc.
