Those involved in the mental health "Recovery Movement" believe the patient is the expert on treatment rather than the doctor and that there is no need for clinical evaluation or evidence-based treatment. This model does not accommodate the needs of individuals with severe mental illness who may lack insight into their illness and are unable to make appropriate treatment choices.
Current anti-stigma campaigns emphasize that most people with mental illnesses aren't violent. This is very true. They also point out that people with mental illnesses are much more likely to be the victims of violence rather than the perpetrators. Also true. But the research is clear that people with untreated psychosis are a greater danger to themselves and others than people who aren't psychotic. People with untreated psychotic disorders have a higher rate of violence than do the general population.
