> Dr Barack and his colleagues collected data from 457 adults who completed an online foraging game where they had to collect as many berries as possible within eight minutes.

So as I understand it, ADHD in that setup basically introduces chaos / randomness to avoid falling into local optima.

It immediately follows that having ADHD may be a major disadvantage in environments where there is only one global optimum (for example, a highly regulated and deterministic academic environment like school or undergraduate studies, or an established corporate environment).
