Abstract

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.

Highlights

To deny or overlook the humanity of others is to exclude them from one of the core category memberships that all people share. Still, research suggests that individuals engage in dehumanization surprisingly often, both in subtle ways and, in certain contexts, by blatantly associating other groups with ‘lower’ animals.

We review evidence highlighting the plethora of distinct ways in which we dehumanize, the consequences dehumanization imposes on its targets, and intervention efforts to alleviate dehumanization.

We provide a framework to think about different operationalizations of dehumanization and consider how researchers’ definitions of dehumanization may shape the conclusions they draw about key questions such as the association between dehumanization and violence.

We address a number of theoretical challenges to dehumanization research and lay out several important questions dehumanization researchers need to address in order to propel the field further forward.
