Confucius's most underrated line isn't about virtue — it's about language. In the Analects, when asked about governance, he replies: 'If names are not correct, speech does not accord with truth.' This is the doctrine of zhengming, the rectification of names — and it has a sharp edge for anyone who builds products or leads teams. Every mental model is, at its core, a naming decision. When you call something a 'funnel,' you've already decided it's linear, that volume is the primary variable, and that leakage is the failure mode. The name recruits the model; the model recruits the strategy. You aren't choosing a framework after perceiving reality — the name shapes what you perceive. The practical consequence is uncomfortable: before you deploy a mental model, the more useful question is not 'does this model apply?' but 'what does this model's name make invisible?' Funnels erase network effects. 'Sprints' erase the compounding value of slow work. 'Stakeholders' erase the difference between someone with a vote and someone with skin in the game. Zhengming isn't pedantry — it's the upstream act that determines everything downstream.

Pick the mental model you've used most this week — what does its name assume that you've never explicitly agreed to?
