I'm not sure why they would think that in the case of willow or bean but have read that some pdocs especially at the VA get people faking it to claim disability or people who get some symptoms from illicit drug use that mirror psychosis and could be treated by cutting out those drugs but would prefer disability. The thing is they probably don't plan on taking meds long term...most people are not forced to but you kind of have to in the hospital. I read an account of one guy that did this and went back complaining to his doc after taking an AP he said he felt trapped in a box or something like that...never faked voices again.
