This reminds me of the bicameral mind hypothesis. Certain people (corresponding to your “schizophrenic side of the schizophrenic-autistic spectrum”) may well still receive the results of unconscious processing as “voices in their head” rather than a coherent deliberation on all facets of the truth. (The bicameral mind hypothesis holds that said “voices” are the ancestral condition, which is probably unprovable but intriguing nevertheless.)
