More of the same, not that it would convince the Lunatic Left.
Only those moving into diverse communities – presumably voluntarily – do not suffer the negative effects. Although for even this group, I can imagine those forced to move toward diversity for economic reasons would suffer; thus, only those who move toward diversity because they (stupidly) value diversity itself would be unaffected. The abstract:
Studies demonstrate a negative association between community ethnic diversity and indicators of social cohesion (especially attitudes towards neighbours and the community), suggesting diversity causes a decline in social cohesion. However, to date, the evidence for this claim is based solely on cross-sectional research. This article performs the ﬁrst longitudinal test of the impact of diversity, applying ﬁxed-effects modelling methods to three waves of panel data from the British Household Panel Survey, spanning a period of 18 years. Using an indicator of affective attachment, the ﬁndings suggest that changes in community diversity do lead to changes in attitudes towards the community. However, this effect differs by whether the change in diversity stems from a community increasing in diversity around individuals who do not move (stayers) or individuals moving into more or less diverse communities (movers). Increasing diversity undermines attitudes among stayers. Individuals who move from a diverse to a homogeneous community report improved attitudes. However, there is no effect among individuals who move from a homogeneous to a diverse community. This article provides strong evidence that the effect of community diversity is likely causal, but that prior preferences for/against out-group neighbours may condition diversity’s impact. It also demonstrates that multiple causal processes are in operation at the individual-level, occurring among both stayers and movers, which collectively contribute to the emergence of average cross-sectional differences in attitudes between communities. Unique insights into the causal impact of community disadvantage also emerge.
