philosopher v syag, I agree with each on separate issues – there is COVID but not ADHD or 80% of it, to be more accurate.
To add to on ADHD/creativity connection, fMRI seem to show that ADHD connection “misfire” so that a signal goes to multiple locations instead of (intended?) one. Of course, one might argue whether activating multiple connection is a bug or a feature, as programmers say.
Historically, it may have been more important for 99% of population to memorize and follow instructions to survive. 1% had a luxury to be creative. In industrial age, machines were built for right-handed only. Currently, we have computers to make computations, google to look up statistics, Sefaria to look up Mishna, and so many people having more “free” time on their hands than ever.
So, the people who make those unusual connections are more and more valuable.
Of course, you don’t just “ignore it” – you need first to build the kid’s confidence after all negative feedback he was getting from school. Best is to study something interesting with the kid, until he becomes good at it, better than peers and teachers. Then, you need to give him skills to use his abilities: build something tangible rather than just imagine something that does not make sense. Then to deal with the lack of skills – practice at least some attention to detail, search Internet for things he does not remember, make lists of things not to forget, partner with others with different skills.
