There is a certain high-level pattern of progress seen in almost every human activity, which I like to call “growth triplets”. A growth triplet follows an archetypal sequence of three stages: naive, clever, and wise, with the exact meanings of these terms varying depending on the situation. The defining feature of the pattern is that the third stage has some unexpected similarities to the first one. Because of this, most people have to actually go through the second stage before they can appreciate the third.
You can find several examples in this Scott Alexander post, and recently I hinted at many others:
life/performance/improv
thesis/antithesis/synthesis
tribalism/rationality/post-rationality
brains/computers/neural nets
