Are thinking problems a category of problems? It’s a kind of problem. What makes a problem a thinking problem? How do they relate to all kinds of problems? Are all problems a thinking problem? They’re in our heads so we think about them. Even if it’s subconscious or not.
Us being not aware of thinking problems is an issue. That’s something to work on. That’s what postmortems are for. I think they help us find the problem.
Also, us not being aware of thinking problems sets up the problem in two parts: There’s identifying the problem and then fixing it. If we knew all our problems then we can just get right to fixing but that’s information we don’t know about. Is learning about problems knowledge about the problem? That way it helps us solve the problem better? Karl Popper dealt with that in a way when solving induction. He had to reformulate the problem first before finding a solution for it.
It’s also important to note that the thinking problems in the quote are “important”. They may be holding us back in some ways that prevents us from reaching our goals. I think they’re related to us making many of our errors.
