A model that worked in one domain gets copied into another and quietly stops being true.
A useful law travels because it names a structure, not a costume. If it only works when you keep the original vocabulary, it is a local habit. Carry the mechanism — feedback, constraint, selection — and leave the brand behind. The test is whether a stranger in another field can run it this week.
Practice
Take one model you trust. Restate it in one sentence with no house terms. If you cannot, it is not portable yet.
