I the schizophrenic people I know are afraid of authority and avoid anything that might diagnose them. It takes a forceful family member to get them to a doctor (or in one case the prison system), and constant attention to get them to take the treatments. In general if they are not a harm to society or themselves it is best to let them live alone in a small town (small town because it gives the town gossips something useful to talk about: the talk helps ensure everybody knows to watch out for the victim, and small ensures even new people in town know about the situation)

Note, my sample size is far too small to draw universal conclusions about schizophrenic.
