> Shizophrenia was a good trait for aeons, when it came to beeing a priest/shaman, a artist or simply some loner hunter, who could follow prey for weeks without the onslaught of isolation anxiety.
I'm not sure how useful schizophrenia would be as a hunter. Being a hunter requires a high degree of inhibitory control and some level of metacognitive ability. Wouldn't constantly hearing voices all the time distract the hunter from hunting and tracking his prey down?
My only half-serious musing is that, as with autism, we're all somewhere on the schizophrenic spectrum, in some sense. Hearing one voice in your head is a step above hearing none. Having multiple voices, sourced from different subconscious processes, yet only heard one a time and that you can't distinguish between thus perceiving as a single "you", might be a step above just one.
AFAIK schizophrenic voices are perceived as indistinguishable from actual, external voices of other people talking. It's a different thing than hearing a voice in one's head and this is what sets schizophrenics apart, not the number of distinct voices.
