It was a long time ago, but I recall reading once that in some cultures the voices and delusions of schizophrenics tend to be of a more positive nature. In our culture they tend to be almost entirely menacing, paranoid, accusatory, etc.

Makes me think about set and setting with psychedelics. Maybe our schizophrenics have menacing delusions because our culture is full of hostility and negativity.

There are counterexamples in our culture though. You find them in the new age, occult, and some religious communities. I think some channelers, alien contactees, prophets, etc. probably are schizophrenic but some of them relate positive experiences and messages. Maybe high functioning schizophrenia is just a very non-neurotypical edge case.

I'm not downplaying the other aspects of this case though. In this case actual novel and objectively verifiable information seems to have been learned. It's a particularly compelling one because it happened under the loose observation of medical professionals, but if you talk to people you hear less extreme anecdotal experiences like this all the time. I've heard tons of parents tell me stories about spooky parental intuition, things like "knowing" that a child is in danger and going and saving the child just in time.

I'm an open minded skeptic on this stuff. I tend toward the skeptical but don't completely dismiss it. Speaking of delusions, the idea that after methodically doing science for only ~200 years we know everything is a peculiar delusion of our culture.

Always makes me think of this:
