People with "analytical
autism" are autistic people who used to be diagnosed with Asperger's syndrome. They are verbal and thoughtful, especially interested in structured, predictable systems, including logic, patterns, categories, and rules.
Primanauts is short for Primary Analytical
Autism, the main group.
Extanauts is short for Extended Analytical
Autism, nerdier people, including those excelling in academic disciplines, including math, science, and law- often earning graduate degrees.
My brother and I went to a
special school for kids on the
autism spectrum, those with analytical
autism. They put me with the other extanauts, since I like more challenging material. My brother is with the primanauts.
