> It is often cited as exactly the reason, and appears to be the scientific consensus. In fact you can see large swings in diagnosis numbers based on socioeconomic factors[0], which definitely hints at diagnostic bias. A counterthesis based on personal observations: let us assume that there exists a genetic reason for ASD (plausible), assume that ASD people tend to work in specific jobs in specific branch of the economy (think software development and/or research) - also very plausible. Now, additionally, assume (again very plausibly) that people look for potential partners in their social milieu and finally assume that people with similar (also slightly autistic) traits fit better together in a relationship. This, in my opinion, explains quite well why there is a lot of inbreeding between people with a slight Asperger bias which, by genetics, leads to an increase of autism presence (and thus diagnoses) in specific socioeconomic milieus without any diagnosis bias.
