Sanism, saneism or mentalism refers to the systemic discrimination against or oppression of individuals perceived to have a mental disorder or cognitive impairment. This discrimination and oppression are based on numerous factors such as stereotypes about neurodiversity. Mentalism impacts individuals with autism, learning disorders, ADHD (attention deficit hyperactivity disorder), FASD (fetal alcohol spectrum disorder), bipolar, schizophrenia, personality disorders, stuttering, tics, intellectual disabilities, and other cognitive impairments.
Mentalism may cause harm through a combination of social inequalities, insults, indignities, and overt discrimination. Some examples of these include refusal of service and the denial of human rights.
Mentalism does not only describe how individuals are treated by the general public. The concept also encapsulates how individuals are treated by mental health professionals, the legal system and other institutions.
The term "sanism" was coined by Morton Birnbaum, a physician, lawyer, and mental health advocate. Judi Chamberlin coined the term "mentalism" in a chapter of the book Women Look at Psychiatry.
The terms mentalism, from "mental", and sanism, from "sane", have become established in some contexts, although concepts such as social stigma, and in some cases ableism, may be used in similar but not identical ways. While mentalism and sanism are used interchangeably, sanism is becoming predominant in certain circles, such as academics. Those who identify as mad, mad advocates and in a socio-political context where sanism is gaining ground as a movement. The movement of sanism is an act of resistance among those who identify as mad, consumer survivors, and mental health advocates. In academia evidence of this movement can be found in the number of recent publications about sanism and social work practice.
The term "sanism" was coined by Morton Birnbaum during his work representing Edward Stephens, a mental health patient, in a legal case in the 1960s.
