A measurement regime is the total system of proxies, metrics, and evaluation frameworks that governs a particular domain, together with the institutional infrastructure that produces, validates, and enforces them. It includes not just the proxy measures themselves but the organizations that collect data, the software that aggregates it, the protocols that validate it, and the incentive structures that reward compliance. Measurement regimes are not neutral technical apparatuses. They are systems of power that determine what counts as valid knowledge and what counts as legitimate action.

The performative character of measurement regimes is their most consequential property. A credit score does not merely assess creditworthiness; it shapes the economic opportunities available to the scored, which in turn shapes their creditworthiness. A hospital readmission rate does not merely measure care quality; it reshapes discharge protocols, patient triage, and even who gets admitted. The regime brings into being the condition it purports to describe. This is performative measurement: the production of reality through the act of measuring it.

The political question is not whether measurement regimes are accurate but whether they are contestable. A regime whose proxies are treated as objective facts rather than designed instruments is a form of epistemic closure. The task of critical systems theory is to render these regimes visible as designed systems — to ask not just is
