Evidence for blatant dehumanization of mental illness and its relation to stigma

People with mental illness face stigma, and due to their low social status, they may also face blatant dehumanization that denies their status as fully evolved human beings. In the current research, three studies documented the existence of blatant dehumanization of mental illness. Study 1 (N = 112) showed that participants rated people with mental illness in general as being significantly less human than other dehumanized social groups such as Mexican immigrants and Muslims. Study 2 (N = 158) showed that dehumanization occurs for specific mental disorders but that the level of dehumanization varies widely among disorders. Study 3 (N = 223) documented significant correlations between dehumanization of mental illness and standard measures of stigma such as fear, pity, and social distance. Overall, the results establish the relevance of blatant dehumanization to mental illness stigma and suggest new directions for understanding stigma.
