群体间接触的影响长期以来一直是社会科学家的核心问题。随着政治和技术变革带来国际移民的增加，了解群体间接触对于科学和政策辩论变得越来越重要。不幸的是，使用观察数据进行因果推断的局限性以及实际上无法通过实验操纵人口多样性限制了学者们解决群体间接触影响的能力。在这里，我报告了一项随机对照试验的结果，该试验测试了反复群体间接触的因果影响，其中讲西班牙语的同盟者被随机分配到生活在美国同质社区的不知情的盎格鲁白人的日常生活中一段时间，从而模拟人口变化的条件。这项实验的结果是，接受治疗的受试者的排斥态度发生了重大转变。这个实验表明，即使是非常微小的人口变化也会引起强烈的排斥反应。随着国际移民带来群体间接触的增加，发达国家和政治自由的地方单位预计将经历政治保守的转变。
The effect of intergroup contact has long been a question central to social scientists. As political and technological changes bring increased international migration, understanding intergroup contact is increasingly important to scientific and policy debates. Unfortunately, limitations in causal inference using observational data and the practical inability to experimentally manipulate demographic diversity has limited scholars' ability to address the effects of intergroup contact. Here, I report the results of a randomized controlled trial testing the causal effects of repeated intergroup contact, in which Spanish-speaking confederates were randomly assigned to be inserted, for a period of days, into the daily routines of unknowing Anglo-whites living in homogeneous communities in the United States, thus simulating the conditions of demographic change. The result of this experiment is a significant shift toward exclusionary attitudes among treated subjects. This experiment demonstrates that even very minor demographic change causes strong exclusionary reactions. Developed nations and politically liberal subnational units are expected to experience a politically conservative shift as international migration brings increased intergroup contact.
