A publicized series of police (and other) violence against unarmed Black people over the last decade has fueled unprecedented mass protest as well as political and policy debate in the United States, and beyond. Given this ethical dispute over whether democratic society upholds its cardinal values of freedom and equality for all, sentiment toward Black Lives Matter is suggestive of what people believe police killings, and protest against them, say about the state of democracy itself. In this review, we use the latest empirical evidence in psychology and related sociobehavioral sciences to document sentiment regarding Black Lives Matter. Because continuing racial inequity is a foundational assumption of Black Lives Matter, we will also review the most relevant studies of attention to, knowledge of, and beliefs and feelings about police violence and related acts and issues that may be viewed as indicating racial inequity. Much of this work shows a dramatic divergence of sentiment across racial and political lines, as increased social and political polarization and insulation evidences in divergent attention, cognition, affect, emotion, motivation, and action regarding relevant events and social issues. In this way, examinations of the psychology of such sentiment reveal just how deep the social and political rifts run in society.

了解对“黑人的命也是命”的看法

在过去十年中，针对手无寸铁的黑人的一系列公开的警察（和其他）暴力行为在美国及其他地区引发了前所未有的大规模抗议以及政治和政策辩论。鉴于关于民主社会是否维护其人人享有自由和平等的基本价值观的伦理争议，对“黑人的命也是命”的情绪暗示了人们对警察杀戮和抗议的看法，以及对民主状态本身的看法。在这篇评论中，我们使用心理学和相关社会行为科学的最新经验证据来记录关于 Black Lives Matter 的情绪。因为持续的种族不平等是 Black Lives Matter 的一个基本假设，我们还将回顾最相关的关注、知识、以及对可能被视为表明种族不平等的警察暴力和相关行为和问题的信念和感受。这项工作的大部分显示出跨种族和政治路线的情绪存在巨大差异，因为社会和政治两极分化的增加以及对相关事件和社会问题的不同关注、认知、情感、情感、动机和行动的隔离证据。通过这种方式，对这种情绪的心理学研究揭示了社会和政治裂痕在社会中的深度。和有关事件和社会问题的行动。通过这种方式，对这种情绪的心理学研究揭示了社会和政治裂痕在社会中的深度。和有关事件和社会问题的行动。通过这种方式，对这种情绪的心理学研究揭示了社会和政治裂痕在社会中的深度。
