Maybe this will be helpful? (unless you already have this one).

Neat topic - very suggestive, thank you. Various "schisms" exhibit almost an "escape" from a sort of anticipatory myopia (even if those breaks are maladaptive with respect to the continuing external world). Is SZ, then, an attempt by "nature" to free itself from a cognitive compulsion (an "unnatural" but requisite causal process) which cannot be won? Thoughts? Just trying a unique perspective. As in the above case, SZ is non-normative, but somehow "more natural and objective" and less inclined to inattentive, expectational bias. A break from basal loops which are not getting anywhere (but with no alternate place to go).

Being both schizotypal and ASD myself, I would say that it is *any* non-normal state of consciousness which allows one to bypass normal expectations (cultural or personal), and the only "advantage" that SZ itself might have is that it is non-normal; however, it is not recommended (as if it were choice-based) due to its chaotic effects. There are very many other ways of achieving sufficiently non-normal states which can be controlled: trance, certain drugs, meditation, and ritual practices. In my own case, my obsessive tendencies urge me toward confirmatory bias, but my state-altering practices tend to balance such urges, more or less. I see that I am even doing that here, in composing this note.
