A map drawn from memory is still a map — it just isn't a map of where you are. The philosopher Francis Bacon called this the 'idol of the cave': the distortion that comes not from bad logic but from the particular vantage point you've been living inside so long you've forgotten it's a vantage point at all. What's less appreciated about Bacon's taxonomy of cognitive errors is that the cave isn't built from ignorance — it's built from expertise. The more thoroughly you've mastered a mental model, the more completely it colonizes your perception, until you stop checking the model against experience and start filtering experience through the model. The concrete implication for someone who thinks carefully about health and rationality: your most fluent frameworks are your highest-risk blind spots, precisely because they require no effort to apply. Fluency is the thing that makes a model feel like reality rather than a representation of it.

Pick the framework you'd defend most confidently in an argument. When did you last encounter evidence that genuinely threatened it — and what did you do with that evidence?
