Increasing diversity and the anticipation of its resulting cultural change is raising vociferous protestations among White Americans. Here, we explore moderation and mediation of its intergroup implications. Among a nationally representative sample of White Americans, Study 1 (n = 2,257) revealed that living in a region that experienced a greater (vs. lesser) increase in racial diversity in recent years was associated with more anti-immigrant attitudes, but only among those who were highly White-identified. In an experiment, Study 2 (n = 420, White Americans) revealed that collective nostalgia (i.e., longing for the ingroup’s past) mediated the relation between anticipated cultural change resulting from shifting demographics and anti-immigrant attitudes, but only for those who were highly White-identified. Thus, anti-immigrant sentiment among White Americans in response to changing demographics and culture is seen primarily among those personally invested in their White racial identity, an effect partly explained by a longing for bygone days.

日益增长的多样性以及由此产生的文化变革的预期正在美国白人中引发强烈抗议。在这里，我们探讨了其群际影响的适度和调解。在具有全国代表性的美国白人样本中，研究 1 ( n = 2,257) 显示，生活在近年来种族多样性增加较多（相对较少）的地区与更多的反移民态度相关，但仅在那些高度认同白人的人。在一个实验中，研究 2 ( n= 420，美国白人）揭示了集体怀旧（即对内群体过去的渴望）调节了人口结构变化导致的预期文化变化与反移民态度之间的关系，但仅限于那些高度认同白人的人。因此，美国白人对人口结构和文化变化的反移民情绪主要体现在那些个人投资于白人种族身份的人中，这种影响部分可以解释为对过去日子的渴望。
