Everyone's a little bit ADHD
This is a phrase I've run into a lot, and ... well, I'd like to talk about it a bit, because I think there's some nuance there that's worth appreciating.
Because it's technically correct (the best kind of correct) but practically wrong.
Technically correct
ADHD is a spectrum disorder - there's people with it hitting them harder than others, and it's all about a threshold of 'Significant Life Impact' for that last "D" - Psychiatric Disorder - to 'kick in'.
So there's also a load of people who are sub clinical for ADHD out there. Who don't cross the threshold at this time in their life. But might later. Or might not.
And more still who are a 'little bit' ADHD, because ADHD hits executive function, and no one has perfect executive function. (Well, ok, maybe there are some people, but I'm pretty sure they're very rare).
The difference though between working memory being a little bit impaired, and it being almost useless, almost all the time is huge though. It's the same thing at a fundamental level but one is mildly inconvenient, and the other is a disability.
So I do appreciate - sometimes - where a person is coming from when they say 'everyone is a bit ADHD' - because they might well be trying to show empathy, rather than trying to invalidate a very real disability.
It also makes a pretty good conversation opener, to explore quite why that statement is so loaded, and how the nuance is important to understanding ADHD.
Yes-but-no
Ignorance is fixable, especially if the person already shows empathy. Willful ignorance though? Well, that just makes you a bad person.
