Incommensurability is a human-made concept in philosophy of science and decision theory denoting the absence of a shared measure or common standard for comparing two or more values, theories, or frameworks. It carves the condition where no single metric exists that can fairly rank alternatives across domains — for example, utility versus justice, or paradigm A versus paradigm B. The concept persists through philosophical argument, scientific methodology, and institutional decision processes that must handle trade-offs across incommensurable grounds.

Incommensurability is the property of things that cannot be measured on a common scale. It is defined entirely in relation to measurement systems — without measurement, the concept is meaningless. Remove measurement and incommensurability cannot operate; the dependency is CONSTITUTIVE.
