There is no flavour of adhd that does this, their intelligence spans the same ranges as any other people. But they do have a lower attention span which is why I referred to them,

The article literally refers to “lower measured attention span” as “being dumber” and thats just unapologetically incorrect.

That said there are so many different kinds of intelligence that we don’t measure or have tests for, being bad a one that does have tests is indeed nothing to be ashamed for, you are correct on that part.
