Because behavior is multidetermined, racism most likely has biological, psychological, and sociological origins. However, the psychiatric community has been reluctant to consider whether or not some forms of racism are manifestations of psychiatric disorders or constitute a psychiatric disorder. Maybe the question of racism as a mental illness is so contentious that it precludes consideration of the issue at all. We should let science, not our personal opinions, answer these questions. Maybe we should go a step further, and if some types of racism are found to be a mental illness or a symptom of a mental illness, developers of the next DSM should consider including other extreme prejudices, such as sexism, ageism, and heterosexism. Accordingly, some have proposed to examine "pathological bias" in a clinical context, because such an approach may lead to effective intervention with and treatment of individuals who manifest such problems.
