People’s proclivity for favoring their ingroups over outgroups has negative consequences for individuals, groups, and societies. Social psychologists have explored a variety of techniques to reduce these intergroup biases. Emerging research suggests that mindfulness may be effective for this purpose. Mindfulness is defined as present-moment attention and awareness with an accepting attitude, and it is often cultivated through meditation. Our systematic review of the mindfulness-intergroup literature suggests that, across the heterogeneity of paradigms, mindfulness attenuates intergroup bias. Supporting this supposition, for all studies in the current review, regardless of operationalization of mindfulness (i.e., mindfulness-based intervention, brief mindfulness induction, expert meditators, dispositional mindfulness), the overall effect size was g = +.29 (k-number of studies = 36; 95% CI [0.20, 0.39]; Z = 5.94, p < .0001), suggesting a small but significant effect of mindfulness on improved levels of intergroup bias. In the current work, we review the eligible studies and their findings in detail and conclude by discussing critical issues and implications for future research.

人们倾向于偏爱自己的群体而不是群体，这会对个人，群体和社会产生负面影响。社会心理学家已经探索了各种减少这些群体间偏见的技术。新兴研究表明，正念可能对此有效。正念被定义为当前时刻的注意力和意识，并带有一种接受的态度，并且通常通过冥想来培养。我们对正念-群体间文献的系统回顾表明，在范式的异质性中，正念减轻了群体间的偏见。支持这种假设的是，对于本综述中的所有研究，无论正念的可操作性（即基于正念的干预，短暂的正念诱导，专家冥想者，性格正念），总的影响大小均为g = +.29（k项研究= 36； 95％CI [ 0.20，0.39 ]；Z = 5.94，p <.0001），表明正念对小组间偏见水平的提高有很小但很明显的影响。在当前的工作中，我们将详细审查符合条件的研究及其发现，并通过讨论关键问题及其对未来研究的意义进行总结。
