自Allport发表他的原始研究报告以来,多年来,研究人员一直试图通过经验检验与其他群体的接触是否可以减少偏见。 在2006年的一篇论文中,Thomas Pettigrew和Linda Tropp进行了荟萃分析:他们回顾了500多项以前的研究的结果(约有25万研究参与者),并为接触假说提供了支持。 此外,他们发现这些结果不是由于自我选择(即,偏见较少的人选择与其他群体接触,而偏见较大的人选择避免接触),因为即使参与者参加,接触也具有有益的作用。 尚未选择是否与其他团体的成员联系。 虽然在种族偏见的背景下最经常研究接触假说,但研究人员发现,接触能够减少对各种边缘群体成员的偏见。

Since Allport published his original research report, researchers have been trying for years to empirically test whether contact with other groups can reduce bias. In a 2006 paper, Thomas Pettigrew and Linda Tropp conducted a meta-analysis: they reviewed the results of more than 500 previous studies (about 250,000 study participants) and provided support for the contact hypothesis. In addition, they found that these results were not due to self-selection (ie, people with less prejudice chose to contact other groups, while those with greater bias chose to avoid contact) because contact had a beneficial effect even if participants participated. Have not chosen to contact members of other groups. Although the contact hypothesis is most often studied in the context of racial prejudice, the researchers found that exposure can reduce prejudice against members of various marginal groups.
