How do we explain the abnormal prevalence and persistence of schizophrenia? There's the theory that our tribes needed shamans and a religion to maintain unity so it was incentivized, there's another theory that it's a byproduct of language evolution, or perhaps the other one that says that promoting extreme delusions can be highly beneficial for personal gain in primitive societies, or maybe the other 10 or so all saying the same thing - the evolutionary benefits outweigh the negatives.
So what's happening here, /sci/?

>Contrary to the previous view, there are models rooted in theories that view schizophrenia as granting beneficial powers to patients, their kin, or their social groups. This view attempts to explain the prevalence and persistence of schizophrenia over time and across cultures. Researchers, Joseph Polimeni and Jeffrey Reiss, argue that the existence of schizophrenia in humans is not random, basing this argument on the fact that the 1% prevalence rate is higher than gene mutation rates.
