So what does it mean by four "factors"? If you have some or all of these symptoms, you're on the psychosis spectrum? Because I definitely have cognitive disorganization and impulsive noncomformity, and some unusual experiences. I hallucinated once during a bad panic attack, and I do have some odd beliefs that I can't explain. Then again, so do religious people. There's a big gray line there, to me.
And if the ones who say schizotypy is a genetic vulnerability to psychosis are right, I'm screwed. Dementia runs in the family, and my grandmother who didn't have dementia would sometimes tell stories that never happened, or change major details, without seeming to know it.
