Simplicity is not natural. Over-complication is the default, people assume social reasons are the main reason for over-complication but I think it’s an unparsimonious and false model.
I dislike overcomplication and spend a significant amount of my time on trying to come up with more simple understandings or portrayals of topics that other people find complicated.
But I think the most common lay model of overcomplication is wrong. I think a lot of people have a natural tendency/theology of "simplicity" that I covered in the plain language section of my writing styles guide, something like:
The truth is simple and obvious. Smart alecs try to overcomplicate things, either due to personal insecurities or institutional/social reasons (can't get tenure/promotions from doing easy things),
Because the truth is obvious, anybody can find it. Children often find it first. They haven’t learned to complicate things.
I disagree. I think the reason things are (over)complicated are due more to a combination of "territory" and cognitive reasons than due to social or institutional reasons.
Put a different way, I think finding the truth is often hard. And once you do find the truth, finding a simpler way to express the same truth is also hard (and requires significant cognitive effort, parallel searches, and in some cases significant serial time).
Calculus went from something that the greatest minds of Newton's generation could barely understand to something that's a rite of passage for smart high-schoolers. I think the difficulty change is mostly due to coming up with better explanations, pedagagogy, and advances in the conceptual technology of intermediate steps, not due to social reasons like people being too arrogant to understand the deep truths of calculus.[1]
I don't currently have a great model of why simplicity is difficult. Two models I'm playing around with are the Lottery Ticket Hypothesis-adjacent models and Grokking-adjacent models. (I currently think the former is more plausible).
I'm not saying people never overcomplicate things for non-epistemic reasons. Motivated reasoning, for example, is a real, commonplace, and persistent problem (see here for an example). But in situations where nobody proffers a good explanation (rather than just some people "mysteriously" not understanding obvious concepts, or running interference), I think the more parsimonious explanation is a combination of the lack of skill and lack of motivation/effort/serial time invested so far in coming up with a better explanation, rather than that the good explanations are out there and individual or institutional factors actively hide it.
(This is also another angle in which I disagree with the implicit telos of the midwit meme).
People being individually smarter via better nutrition and and lower parasite load also plays a role, but I think lower
I think people overcomplicate explanations because they don't arrive to the truth immediately (e.g. by enumerating all possible answers, ordered by length) but basically by semi-randomly walking in a maze of hypotheses and finally stumbling upon the truth -- so their path is not necessarily the shortest path.
(Later people travel the maze more, and notice shortcuts.)
Like, someone considers an option A, it is wrong, but seems kinda correlated. So afterwards they try "A and B", and it works. They don't notice that B alone would have worked too, because they a... (read more)
