Here's a strange failure mode that almost no one catches in themselves: the more expert you become at something, the more likely your mental models are to *stop updating* — because expertise feels like arrival. Hegel called this the trap of 'Verstand,' the understanding that fixes and freezes what is actually fluid and alive. Meanwhile, Charles Sanders Peirce, the pragmatist, argued that a belief is only meaningful insofar as it changes what you'd do when confronted with new evidence. Put those two ideas together and you get a sharp diagnostic: if your mental model of something — your team, your health, your relationship, a market — hasn't been revised in the last six months, it's probably a relic, not a map. The Hegelian move isn't to throw the model out; it's to treat contradiction as signal, not noise. When reality pushes back today, ask whether you're updating your model or defending it.

When did you last genuinely revise a mental model you hold — not tweak it around the edges, but actually change the underlying structure? What would have to happen today for you to do that?
