Most of the maps in your head were drawn by someone else. Confucius, in the Analects, kept returning to a practice he called 'rectifying names' — the insistence that before you act or judge, you check whether the word you're using actually fits the thing in front of you. The mental model isn't wrong because it's old; it's wrong because the territory shifted and you never updated the label. Today, pick one belief you're using to navigate a recurring problem — about your body, your work, your relationships — and ask honestly: did I test this, or did I inherit it? The map and the ground are different things, and Sunday is a good day to notice the gap.

What is one mental model you are currently using that you have never actually tested against your own experience — only assumed to be true?
