My guess is because we have to develop creative problem solving skills in order to mask symptoms to avoid the stigma of ADHD or accomplish a similar level of productivity or accomplishment in work/life as those without ADHD.
Creativity and ADHD/neurodiversity has long been associated with each other but I don’t think the reason is predominately due to the brain wiring but more due to the environment in which we live. It is a coping mechanism for living in a world not built to accommodate.
True as well, it is most likely a combination of many things, both nature and nurture related.
When is there ever a single cause for a behavior when we are studying a complex disorder with decades of unique life experiences layered on top of each person that affect the symptoms of that disorder?
There are an infinite number of variations and to boil it down to one thing is not helpful.
I didn’t intend for my statement to infer that, apologies if it did.
