Although dehumanization research first emerged following the overt and conscious denials of humanity present during war and genocide, modern dehumanization research largely examines more subtle and implicit forms of dehumanization in more everyday settings. We argue for the need to reorient the research agenda toward understanding when and why individuals blatantly dehumanize others. We review ...

The concept of dehumanization lacks a systematic theoretical basis, and research that addresses it has yet to be integrated. Manifestations and theories of dehumanization are reviewed, and a new model is developed. Two forms of dehumanization are proposed, involving the denial to others of 2 distinct senses of humanness: characteristics that are uniquely human and those that constitute human na...

Dehumanization is a central concept in the study of intergroup relations. Yet although theoretical and methodological advances in subtle, "everyday" dehumanization have progressed rapidly, blatant dehumanization remains understudied. The present research attempts to refocus theoretical and empirical attention on blatant dehumanization, examining when and why it provides explanatory power beyond...

Research suggests that members of advantaged groups who feel dehumanized by other groups respond aggressively. But little is known about how meta-dehumanization affects disadvantaged minority group members, historically the primary targets of dehumanization. We examine this important question in the context of the 2016 U.S. Republican Primaries, which have witnessed the widespread derogation an...

Dehumanization is endemic in medical practice. This article discusses the psychology of dehumanization resulting from inherent features of medical settings, the doctor-patient relationship, and the deployment of routine clinical practices. First, we identify six major causes of dehumanization in medical settings (deindividuating practices, impaired patient agency, dissimilarity, mechanization, ...

Two studies address the role of hormonal shift across menstrual cycle in female dehumanization of other women. In Study 1, normally ovulating women (NOW) and women who use hormonal contraceptives (HCW) are compared in terms of how much they dehumanize other women and two other control targets (men and elderly people). In NOW, the level of dehumanization of other women, but not of men and elderl...

The present research explores the distinct effects of animalistic and mechanistic dehumanization on willingness to help natural disaster victims. We examined Japanese and Haitians, two national groups recently struck by earthquakes. We showed that Italian participants differently dehumanized the two outgroups: Japanese were attributed low human nature (dehumanized as automata), whereas Haitians...

Historically, dehumanization has enabled members of advantaged groups to 'morally disengage' from disadvantaged group suffering, thereby facilitating acts of intergroup aggression such as colonization, slavery and genocide. But is blatant dehumanization exclusive to those at the top 'looking down', or might disadvantaged groups similarly dehumanize those who dominate them? We examined this ques...

People not only dehumanize others, they also dehumanize the self in response to their own harmful behavior. We examine this self-dehumanization effect across four studies. Studies 1 and 2 show that when participants are perpetrators of social ostracism, they view themselves as less human compared with when they engage in nonaversive interpersonal interactions. Perceived immorality of their beha...

Although the act of dehumanizing an outgroup is a pervasive and potent intergroup process that drives discrimination and conflict, no formal research has examined the consequences of being dehumanized by an outgroup—that is, “metadehumanization.” Across 10 studies (N 3,440) involving several real-world conflicts spanning 3 continents, we provide the first empirical evidence that metadehumanizat...
