When I bring up that autism has no consistent biomarker and is diagnosed on behavior alone, one of the ways I get pushback is that it's still a group of symptoms that occurs together often and allows people to benefit from the same advice. Now, even if that was true, I still think it's dangerous to tell people they have different brains without real evidence, but, whatever, let's put that aside for now.
Is the premise even true? Is any of the advice actually good? I've heard a bit of it here and there, and it sounds like it's mostly some variation of "stop masking", with "masking" being their word for making an attempt to learn social skills and follow social norms.
I'm aware they have some research they use to justify the claim that "masking" is bad, but it's really shaky. Basically, they have some questionnaire called the CAT-Q that is supposed to measure how hard you're "masking" and a high score is correlated with lower well being. You can read the questions online, they're phrased to measure how awkward someone feels in social interactions, so obviously it's gonna correlate with more stress, and they use that to jump to the conclusion you should just not bother following social norms.
Surely that can't be right? I can't possibly imagine how it could be helpful to tell people who are already struggling socially to just give up and intentionally commit social faux pas.
