Ahh, my apologies then. Yes, that’s the summary. You’re not the first person to point this out to me, but it turned out that the other reader stopped at ‘A Personal Take’ — which was what I thought happened here! (I was going to look at the essay again and ask myself if I made a mistake, since everyone seems to stop at that heading. It also meant my structure was badly chosen. And then I saw your reply!) Then, to address your idea more directly: I can see where you are coming from, but I think Klein and Kahneman’s definition of ‘has reliable causal cues’ + ‘provides opportunities to learn those cues’ are better filters. Klein studies some incredibly high performing individuals — experts who are able to perform well even in very complex environments. So it’s not always true that complexity of environment determines existence of expertise.
