and you can ask the question of why schizotypy

is ignored which is that by being a developmental disability "autism" avoids the stigma that a diagnosis of severe mental ilness would bring (e.g. confirmed bipolar Kanye West thinks he is autistic, Elon Musk who sure acts like he's bipolar but is not diagnosed also thinks he is autistic) If you told the parents of the kid who's being bullied in first grade who shows some signs of anxiety and seems to be dressed oddly that he has a 10% chance of losing his mind completely as a young adult they'd be horrified. Tell them that he has autism and they can get more resources.

Schizotypy is perceived to be left-wing :)

The less flippant rewording of that is that the schizotypal mindset prefers strong-link "positive-sum" problems
