Everyone has some of the traits, but they don’t have ADHD unless it has enough negative impact to be a disorder.

The problem being a lot of people with it might think the negative impact is a personal failing.
Plus it raises the question of people who would otherwise be said to have it but have developed successful coping mechanisms independently, but what else are you going to do for something you can’t physically test for?
