I don't think it's an entailment of schizophrenia that the sufferer is unaware that their beliefs are delusional. Even with that awareness, a schizophrenic idea can be very compelling. Even people who don't suffer from schizophrenia can get irrational ideas that interfere with their life despite decent self-awareness about these ideas. While schizophrenia can have many very strong symptoms and is obviously not 'psychogenic' (e.g. in a Freudian sense), schizophrenics can and do learn skills to help them feel better and pass better and intelligence is an asset there. I will agree that autism seems MUCH vaguer than schizophrenia as a diagnostic category, but that is also true of most other psychological disorders...
