When I first encountered chess as a kid I thought it was a game about thinking because that's how we played it. I was good at it. Then in high school I've met a kid that wiped the floor with me because he actually was taught how to play chess. I played with him few times until I won once just because he was lulled by a streak of wins. That was enough for me so I stopped bothering him with myself. Later in some other context I played checkers with him which I used played (and loose terribly) with my grandma as a few years old child. It turned out that I'm wiping the floor with him in checkers. He didn't even won once. Then I formed a overgeneralized opinion that games are not using any universal matter of thinking. Any thinking you do for the purposes of games is narrowly tailored to the game itself. Being good at one means you are still terrible at others. I generalized this opinion even more, into all domains of human activity. So now when highly educated geologist claims something about climate or zoologist claims something about vaccines I know that they are beginner level wrong.
