Neither does impulse control and attention span imply anything about intelligence. Framing it like this is kinda offensive to the many smart people who have a flavour of adhd.
Previous science regarding gaming habits of young kids concluded that those that gamed more then x hours a day had improved problem solving skills, cognitive skills and also lower attention span.
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. There is no indication of a proper IQ tests being involved.
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.
