The truth of the matter in a field that still needs more thorough studies and a better understanding in the experts in the field who write the diagnosis? Barkley has a few videos on those with counterpoints, the pattern here is to look if ADHD and autism are actually their focus and in the case of studies, if they take the fundamentals into account. Fundamentals like ADHD most often being hereditary. E.g. I read a study about ADHD self-diagnosis and social media and it completely lacking numbers on how likely a self-diagnosis is correct, whether the subjects had a previous diagnosi like depression (a common mis-diagnosis) or how competent the doctors were in the field of ADHD. That study gets attention, ironically, with its claim that social media causes more self-diagnois, but it's those details you want to watch out for when reading counterpoints.

There's no contradiction between the inability to focus (at will) and hyper focus. As an analogy, a car you build for a land speed record is fantastic at the salt flats but usually really bad when it comes to corners or transporting your groceries.
