In Johnston, Newman and Velez (2015), we examine how personality traits related to uncertainty aversion moderate the effect of local ethnic change on perceived cultural threat from immigrants and on immigration-related policy preferences. In two studies—one observational and one experimental—we find that ethnic change increases perceptions of threat and decreases support for immigration among uncertainty-averse citizens but has the opposite effect for the uncertainty tolerant. Neither study finds evidence for similar associations with levels of ethnic diversity.

更正：美国公众移民的种族变化、个性和两极分化

在 Johnston、Newman 和 Velez（2015 年）中，我们研究了与不确定性厌恶相关的人格特征如何缓和当地种族变化对来自移民的感知文化威胁和与移民相关的政策偏好的影响。在两项研究（一项是观察性研究和一项实验性研究）中，我们发现种族变化增加了对威胁的看法，并减少了厌恶不确定性的公民对移民的支持，但对不确定性容忍者却产生了相反的影响。这两项研究都没有发现与种族多样性水平相似的证据。
