metrologisia

Metrologisia is a term encountered in some scholarly and speculative writings to denote an integrative approach to measurement that aims to unify theory, practice, and governance of measurement across disciplines. It is not a formally established field in major metrology literature, and there is no single accepted definition.

Proposed definitions describe metrologisia as the study of how measurement concepts are formed, validated, and applied in physical experiments, manufacturing, digital data systems, and decision-making contexts. It emphasizes traceability, measurement uncertainty, calibration, and the interaction between instruments, methods, and data interpretation.

The scope is intentionally broad: foundational questions about what constitutes a measurement, methods for evaluating and propagating uncertainty, the design of measurement infrastructures, standards development, and the governance and ethics of measurement in society.

The term appeared sporadically in the 2000s and 2010s in discussions about expanding metrology to new frontiers like quantum measurement, digital twins, and AI-driven instrumentation. However, it has not achieved widespread adoption and remains one of several conceptual frameworks for thinking about measurement.

In practice, metrologisia is often discussed as complementary to traditional metrology rather than a replacement, with emphasis on interdisciplinarity and the social dimensions of measurement accuracy and reliability.

Proponents argue it helps coordinate cross-disciplinary measurement efforts; critics note lack of consensus and potential semantic confusion with established terms. Related topics include metrology, measurement, and calibration.
