Barriers to multiculturalism: In-group favoritism and out-group hostility are independently associated with policy opposition

© 2017, © The Author(s) 2017. Bias in favor of the in-group is a key determinant of discrimination and is thought to be largely independent of, and qualitatively distinct from, out-group hostility. One key difference, according to realistic conflict theory, is that in-group preferences become more closely associated with discrimination when intergroup threat is salient. The current study presents a direct comparison of the level of association of in-group favoritism and out-group hostility with opposition to multiculturalism policies in New Zealand. With both predictors operationalized as affect ratings of warmth and anger across separate models, in-group favoritism and out-group hostility were independently associated with European New Zealanders’ (N = 10,869) opposition to both resource-specific and symbolic policies. Furthermore, in-group favoritism was more strongly associated with opposition to resource-specific policies that represent high realistic threat (compared with symbolic policies). In contrast, out-group hostility was more consistently associated with both policy domains.
