But you are right, the highly intelligent and passably "normal" schizophrenics all seem to be of the paranoid variety. I have a friend of some four decade's acquaintance who suffered adult onset paranoid schizophrenia. He'll call me every month or so. The entire conservation will be completely normal. And then he'll start complaining about the person who lives in the apartment below him, or above him, who is always following him from room to room and thumping the floor or ceiling to disturb him and keep him awake.
Sounds mildly plausible unless you know that he's lived in perhaps two dozen different places in six years and had the same complaint in every apartment.
White adult female, ca., 50 yrs., lesbian, well-educated, superior IQ test scores and manifest accomplishment consistent with measured intelligence:
The woman played in my blues band. We were long-term friends (>10 yrs). She spoke of vague complaints of not being able to find a lover. We worked and socialized together, routinely. She lived with her not-so-elderly mother, who was sharp and attractive. Her mother died suddenly last 2 yrs ago in a car accident. My friend said (about 4 months thereafter) that since her mother wasn't around to watch over, my friend now felt free to "overtly pursue her lover." (her words).
Her lover, my friend said, was a beautiful, sexy world-famous radio dj and vocalist who was going to perform nearby in Columbus, OH. And, who didn't really exist---purely a delusion. But my friend would simply accuse women who looked like her delusion as being her coy lover---thus so, she would pursue, relentlessly, soem innocent victim with the full conviction that that was her lover, "just being a little coy..." she would say. My friend went to the concert (a gay pride event), found her lover and ended up in the Franklin Co. jail charged with menacing with a gun, stalking, etc. She did time in the jail as her sentence and was released with two restraining orders against her being within 500 feet "her lover."
After jail, counseling and proper meds,she was just fine...
Year later: meeting at a bar for our band's new year's gig: My friend shows up at the bar with a wig on, a goatee glued to her face and dressed in a man's suit, complete with white shirt and necktie.
"Donna's in church!" Nan (my friend) said, urgently. "Drive me to the church now!"
"Nan! We're on-stage in 30 minutes, you can't go anywhere!"
"That's it, I'm outta here!" Nan corralled some nameless guy, on her way out of the bar, to "give her an emergency lift." He and her took off in his PU. Nan saw a woman who she thought was Donna, she demanded nameless guy stop the truck. Nan got out and confronted a startled innocent lady, demanded that the lady remove her disguise and show that she was really Donna.
Again, Nan went to jail, with an MO not unlike our astronaut.
