Its not random. The neurodivergent brain lacks the ability to perceive (some aspects of) the virtual social reality as something real and to focus on that. In a startup, where the problems at hand are objectively real, the ADHD hyperfocus can excel. In a typical corporation, where the situation is the opposite, it struggles.
It's obviously true that making outcomes more immediately tangible helps make them more appealing to the ADHD brain (that's a very clear kind of "gamification") but I'm not sure how that disagrees with what I said.
