Mentalism or sanism is a form of discrimination and oppression   because of a mental trait or condition a person has, or is judged to have. This may or may not be described in terms of mental disorder or disability. The discrimination is based on numerous factors such as: stereotypes about neurodivergence (e.g. autism, ADHD, bipolar, schizophrenia, personality disorder diagnoses), specific behavioral phenomena (e.g. stuttering, tics), or supposed intelligence.
