Simone Weil spent years studying factory labor not to understand economics, but to understand what repetition does to the mind — specifically, how it produces what she called 'affliction': a state where a person can no longer imagine alternatives to their current condition. The factory worker stops conceiving of the floor differently because the floor never changes. Weil's insight maps cleanly onto something organizational psychologists call 'cognitive entrenchment' — the mechanism Barry Staw documented in his escalation-of-commitment research, where the longer we've invested in a framework, the less we can generate genuinely novel readings of the same situation. The model doesn't fail loudly. It just quietly stops producing new signals while you keep consulting it. For a PM or leader, the practical implication isn't 'use more models.' It's that the mental models you've held longest deserve the most adversarial scrutiny — not because they're wrong, but because they've had the most time to fuse with your perception of reality rather than remaining instruments for examining it. The check isn't whether the model still explains the data. It's whether you can still surprise yourself with it.

Name the mental model you have held the longest in your work. When did it last produce a genuinely unexpected prediction or reframe — not a confirmation?
