Surprise is qualitative. I was ready for this (left the country 3 years ago, still voted from abroad) but I was fully ready to have been wrong all this time. I'm not used to being this prescient, and it doesn't bode well for the rest of what I think I need to be ready for.
It's not the first I've heard of professionals hating the DSM, the whole of scientific thought exists within capitalism and so its tendencies can't ever be entirely free of capitalistic slant. Being critical minded and well educated (as you appear to be, if I may say so) is perhaps the best we can do.
ADHD is, as I understand it with my shitty, distantly earned BS in psychology, congenital and not acquired. You can't just "catch" ADHD, your brain was born with a neurochemical issue - not that I understand neuroscience well, but the dopamine isn't doing its job of keeping your thoughts on target, hence why only immediately rewarding things seem to be possible sometimes.
There are a lot more diagnoses of late, but I've read that part of it is the war on drugs making the Rx systematically scarce so it's just easier to blame people for seeking care rather than addressing the systemic issues. Sort of akin to blaming the consumer for climate change.
TikTok is probably not helping, and it is easy to become addicted. This is a separate matter however.
Okay folks, I've got the pallet of conical hats with the word DUNCE on them, everyone surprised by this please form an orderly queue.
