Nonconformality

Nonconformality denotes the state or quality of not conforming to a standard, rule, symmetry, or expectation. It is a cross-disciplinary term used to describe deviations from established norms in technology, science, or society. The precise meaning depends on context: it may refer to a defect in a product, a physical theory that lacks scale or conformal symmetry, or a social attitude that resists norms.

In quality management and manufacturing, a nonconformity is a tangible deviation from requirements. When detected, it is recorded in a nonconformance report, segregated from conforming products, and subjected to investigation, disposition, corrective action, and preventive action to restore compliance.

In physics, nonconformality often describes systems or theories that are not invariant under conformal transformations. Nonconformal field theories exhibit scale dependence and running coupling constants; their behavior differs from conformal theories, affecting critical phenomena and hydrodynamic properties. In high-energy and condensed matter contexts, nonconformality arises from intrinsic scales such as mass terms, temperature, or a running coupling, and has implications for calculations and dual descriptions.

In social and cultural contexts, nonconformity (the broader concept) refers to behavior or beliefs that do not align with prevailing norms or expectations. It can reflect individuality, dissent, or alternative subcultures and is studied in sociology and psychology for its social and psychological dynamics.

The term is often paired with its antonym, conformity, and is subject to domain-specific standards.
