No convincing evidence outgroups are denied uniquely human characteristics: Distinguishing intergroup preference from trait-based dehumanization

Still no convincing evidence for cognitive map use by honeybees.

Intergroup bias toward “Group X”: Evidence of prejudice, dehumanization, avoidance, and discrimination against asexuals

Although biases against homosexuals (and bisexuals) are well established, potential biases against a largely unrecognized sexual minority group, asexuals, has remained uninvestigated. In two studies (university student and community samples) we examined the extent to which those not desiring sexual activity are viewed negatively by heterosexuals. We provide the first empirical evidence of inter...

Symbols are not uniquely human

Modern semiotics is a branch of logics that formally defines symbol-based communication. In recent years, the semiotic classification of signs has been invoked to support the notion that symbols are uniquely human. Here we show that alarm-calls such as those used by African vervet monkeys (Cercopithecus aethiops), logically satisfy the semiotic definition of symbol. We also show that the acquis...

Toward a Comprehensive Taxonomy of Dehumanization: Integrating Two Senses of Humanness, Mind Perception Theory, and Stereotype Content Model

We review and integrate existing literature on perceptions of humanness and dehumanization. Synthesizing three independent lines of research (Haslam’s two senses of humanness, mind perception theory, the stereotype content model), we provide a taxonomy of different phenomena (e.g., animalistic and mechanistic dehumanization, objectification, demonization, etc.) that all fall under the broad cat...

They see us as less than human: Metadehumanization predicts intergroup conflict via reciprocal dehumanization.

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 metadehumaniz...
