Which is to say, not really. I say this as someone who has been diagnosed as autistic, and identifies as autistic. All of these diagnoses are presented as clear, well defined constructs that exist in the world, but in reality they’re fictions that that committees have drawn around a vast gradient of human traits.
No individual human truly fits any single diagnosis. For example, I have two family members that depending on how you frame their behaviors could be described as either autistic or narcissistic, yet these are supposedly completely different disorders. Prior to being diagnosed as autistic, I’d been diagnosed with some of the ones suggested in the article as well. Was I misdiagnosed? I don’t think so. None of those constructs are real either. So, they’d not even wrong. For a time, some were useful. Some were harmful. But seeing myself as autistic has been a lot more useful.
What matters to me about identifying as autistic is that it allowed me to find other people who experience the world similarly to me. Until I found other autistic people, I felt like I was a single alien stranded on Earth, alone. Finding other autistic people was like finding out that there were millions of other aliens like me hiding in plain sight.
I hope that someday we can move beyond the 1950s-style nosology of the DSM and have a more rigorous science of mental health, but right now, it’s what we’re stuck with.
Something being a table is a label we slap on it to abstract certain attributes, that allows us to reason about it without having to think about all of the non-table-attributes it has. What do tables do? What can we do with them? We can put things on, eat off them. We can’t feed them to our pets. We can’t use them as a trampoline. The object being “a table” is just a categorization we make to allow us to think about the object; it isn’t something that the object is.
Similarly, people aren’t “autistic”. They’re just people, who have certain traits, which psychiatrists have decided should be lumped into a category called “autism”, because they’ve noticed a cluster of other people who have similar traits. So, from this standpoint, someone “being autistic” does not tell us anything. We can already see that person’s traits or characteristics. That categorization might be helpful to some people, and it might be harmful to other people; and they should use or avoid using it accordingly. But they can choose to do that, because “autism” isn’t a “thing” - it’s a mental construct.
