When a product team debates whether a feature is 'done,' they're usually arguing about two different things without knowing it — the map they built, and the territory users actually inhabit. The 13th-century Japanese Buddhist thinker Dōgen had a striking way of naming this split: he distinguished between 'thinking' and 'non-thinking' — the mind that projects its categories onto experience versus the mind that encounters experience before those categories settle in. Product managers live almost entirely in the first mode: roadmaps, personas, success metrics, all legitimate, all maps. The trap is mistaking fluency with the map for knowledge of the territory. Dōgen's move — and it's a practical one — was to periodically let the map go not to abandon rigor, but to notice what the map had been quietly hiding. Concretely: before your next user interview, try spending two minutes writing down every assumption you expect the conversation to confirm. Then treat the interview as a test of those assumptions specifically, not a search for general insight. You're not emptying your mind — you're auditing your model.

Name one belief about your users that has never been seriously challenged — not because evidence confirmed it, but because no one thought to question it.
