Even so, those archetypes aren't fitting, they're more reversed.I feel like he's talking more about archetypes rather than where they fall on the spectrum of 'little autism or lots of autism' in the strict diagnostic sense.
Low functional autists are often more manipulative than high functioning ones.
Reason being that high functional autists both understand and exert empathy, while low functional usually don't even understand or know of such ideas.
Low functional autists will usually attempt do manipulate people around them by screaming, crying, defecating, lashing out violently selfdestructively. Some bite their hands or hit themselves in the head to provoke concerns from their caretakers.
High functional autists are the ones that often won't stop talking about their favorite subjects, that movie they love, their favorite toy or how much they like that one person.
Anecdotal example, I had to spend 3 hours listening to someone who was considered highly functional explain down to the most minute detail how to wash their clothing.
