Inherited systems persist not because they work but because changing them requires admitting they never did.

Inherited benchmarks crumble
Observation
We keep measuring things that stopped meaning anything.
A measurement is really just a vote from the past about what matters now. When BMI persists nearly two hundred years after invention, when Mercedes builds a 1,150-horsepower electric SUV as if horsepower still signals utility instead of theater, when psychology circles back to Robbers Cave experiments to argue about frames instead of asking whether the frame itself has rotted, we're watching systems run on inertia. The mechanism reveals itself in what doesn't change.
We preserve measurement systems not because they predict the future accurately but because they require no argument to implement, no consensus to replace, no hard conversation about what we actually want to know.

BMW's electric performance SUV performs power in the old gasoline register because the language of horsepower sells better than the language of efficiency, even when efficiency is what the machine actually does. The measurement outlasts the reality it measured.

Anyone building something new who still uses someone else's old yardstick is already compromising the thing they're trying to make, because the metric was designed for a problem that no longer exists in the form it did.
