When a map stops matching the territory, most leaders redraw reality to fit the map. The 11th-century Persian polymath Al-Biruni noticed this same failure mode while documenting Indian science for the Abbasid court — scholars kept forcing foreign knowledge into familiar Greek categories, and in doing so, lost exactly what made it interesting. Modern organizational theorists call this 'category lock,' but Al-Biruni named it more precisely: the refusal to tolerate a period of genuine not-knowing before classifying. His method was radical for its time — he learned Sanskrit, lived among Indian scholars, and suspended his own framework long enough for a new one to form. For product leaders, the equivalent moment is when your existing mental model of a user problem starts requiring too many workarounds to hold. That's not a signal to explain harder. It's a signal to go back to the territory — a user call, a raw support log, a session recording — and let the categories dissolve before you rebuild them.

Name the mental model you've been defending longest in your current role. What evidence have you quietly been explaining away?
