The Eighteen Foundational Postulates
Postulate 18 Domain Principle
Statement
The principles of the MMCM SHALL be applicable across different medical domains and diagnostic contexts.
Definition
A Domain is a defined area of medical practice, knowledge, or diagnostic activity within which a particular medical question is considered.
Examples of domains may include
- neurology,
- orthopedics,
- internal medicine,
- radiology,
- psychiatry,
- laboratory medicine,
- or other medical fields.
The Domain Principle concerns the applicability of the MMCM across such different domains. It does not require the diagnostic methods, expertise, or criteria within those domains to be identical.
Principle
The fundamental principles of medical reasoning defined by the MMCM SHALL remain applicable when the medical domain, diagnostic method, or clinical context changes.
Domain-specific medical knowledge may differ substantially.
The MMCM therefore provides a general methodological framework, while the actual medical content remains domain-specific.
Rationale

Key Message
The medical domain may change. The principles of sound diagnostic reasoning remain.
