For example, you spend years in school being instructed as efficiently as possible in the one right way to do things that was already discovered. You are only rarely or never shown the messy process of trial and error needed to get there, and many really big errors are hardly covered at all (the history of communism didn't even get a look-in when I was at school!).
Another: you're instructed near exclusively by specialists, who are definitionally always right (if you argue with the teacher, you lose).
Yet another: as you progress through the system, you're rewarded as the ideas you handle get more complex. You aren't rewarded for simplicity. You are also rewarded for bullshitting, because just like RLHF, exams don't award points for saying "I don't know" but they can award points for a lucky guess.
These sorts of systems inevitably lead to an assumption that progress is linear, mistakes rare, complexity intrinsically has value, that expertise is nearly infallible, that guessing is OK if you don't know and the situation seems important etc. The longer one spends in education the further from reality these intuitions become, until you reach academia and become a public intellectual who produces the most complex/radical ideas possible based on educated guessing and then ignores whether they work or not.
Life outside the training environment eventually starts to correct these false ideas. You see how many things are tried that fail, how nuanced and ambiguous the value of ideas really is, how complexity blows up in people's faces due to problems they didn't anticipate and so on. You start to value incrementalism, evolutionary processes, systems that gather and aggregate the wisdom of the crowds. You become less impressed with ivory tower intellectuals who think they got it all figured out in advance on a blackboard. You become conservative, and end up railing against the young radicals who have some bright idea for reshaping society by force.
