Despite our many differences, one superordinate category we all belong to is ‘humans’. To strip away or overlook others’ humanity, then, is to mark them as ‘other’ and, typically, ‘less than’. We review growing evidence revealing how and why we subtly disregard the humanity of those around us. We then highlight new research suggesting that we continue to blatantly dehumanize certain groups, overtly likening them to animals, with important implications for intergroup hostility. We discuss advances in understanding the experience of being dehumanized and novel interventions to mitigate dehumanization, address the conceptual boundaries of dehumanization, and consider recent accounts challenging the importance of dehumanization and its role in intergroup violence. Finally, we present an agenda of outstanding questions to propel dehumanization research forward.

尽管我们存在许多差异，但我们都属于的一个上级类别是“人类”。因此，剥夺或忽视他人的人性，就是将他们标记为“其他”，通常是“小于”。我们回顾了越来越多的证据，揭示了我们如何以及为什么巧妙地无视周围人的人性。然后，我们强调新的研究表明，我们继续公然非人化某些群体，公然将它们比作动物，这对群体间的敌意具有重要意义。我们讨论了在理解被非人化的经历和减轻非人化的新干预措施方面的进展，解决非人化的概念边界，并考虑最近挑战非人化的重要性及其在群体间暴力中的作用的账户。最后，
