Dehumanization

Dehumanization is the process, practice, or act of denying full humanity in others, along with the cruelty and suffering that accompany it. It involves perceiving individuals or groups as lacking essential human qualities, such as secondary emotions and mental capacities, thereby placing them outside the bounds of moral concern. In this definition, any act or thought that regards a person as either "other than" and "less than" human constitutes dehumanization.

Dehumanization can be overt or subtle, and typically manifests in two primary forms: animalistic dehumanization, which denies uniquely human traits like civility, culture, or rationality and likens others to animals; and mechanistic dehumanization, which denies traits of human nature such as warmth, emotion, and individuality, portraying others as objects or machines.

It has historically facilitated a broad range of harms, from discrimination and social exclusion to slavery, colonization, as well as other crimes against humanity, and is recognized as a significant form of incitement to genocide.
