My dad and his siblings are very smart (graduate degrees, doctors, all of them). However, the way my dad tells it, my uncle was exceptionally smart growing up, and I wonder if it was due to pre-schizophrenia traits (or pre-diagnosis... who knows).
Despite being asian, my dad was always 'afraid' of smart children. In his mind, schizophrenia was caused by lack of rest and relaxation. He always encouraged my brother and I to relax, and not work too hard. Apparently, it is now known that schizophrenia is correlated with sleep disorders as well.
I guess we are lucky in that my uncle has never been able to do anything wrong. He did attempt murder I suppose (in paranoid delusion), but luckily his brothers stopped him. I suppose it helps living near family and having a lot of siblings. Nowadays he's mostly limited (due to old age) to gathering apostles on the internet for his new religions. Probably the best outcome you can hope for.
I believe the biggest lesson from this article though, is that it is dangerous when we legislate based on hope. The 1950s and 60s saw the beginnings of the desire to eliminate asylums due to civil rights concerns. The 'solution' was a technology that at the time didn't exist, but which they hoped would exist after the law was passed. It is dangerous to create law while ignoring current reality, and depending on hope.
