Effects of absolute levels of neighbourhood ethnic diversity vs. changes in neighbourhood diversity on prejudice: Moderation by individual differences in personality

International audienceThis paper examines drivers of prejudicial attitudes among adults in the UK, focusing on the interaction between ethnic out-group size and personality traits. Leveraging data from the National Child Development Study (NCDS), we use two survey waves carried out in 2000 and 2008, just before and after the EU enlargement policy that drove a wave of immigration in the UK. We test the extent to which personality traits moderate the relationship between both absolute levels and changes in ethnic diversity at the local level, respectively, and prejudice. Key findings suggest that personality traits, in particular one's agreeableness, are important for conditioning how the proportion of non-white British in one's neighbourhood affects out-group attitudes. We observe a tendency towards polarisation in prejudicial attitudes between low-/high-agreeableness residents as their neighbourhoods become more diverse. These findings have important implications for theorising how contextual and individual characteristics jointly affect intergroup relations
