Authority Weight

Authority weight is how much the fact that a particular authority committed should move your confidence — in a specific domain, at the moment of consumption. It is one of five orthogonal facets of trustworthiness (alongside tier, commitment status, atomicity, and epistemic uncertainty). It does not tell you whether the claim is correct; it tells you how much standing the committer brings to the bind.

Four components can each be recorded and examined: track record and qualification (epistemic — how well the committer reads evidence in domain), certification and authorisation (legitimacy — social license and entitlement to bind). Certification does not make the same judgment better; it legitimizes scope and accountability. Legitimacy chains lose standing downstream — parallel to data processing inequality — developed in When Social Stability Matters More Than Quality.

Positional authority is conferred by rank — the right to decide and make decisions stick. Epistemic authority is earned by being right — standing in the domain with no official grant. When they diverge, systems that assign weight by rank rather than standing bury valuable truths; immutability of facts at least prevents erasure from the record. Healthy systems let weight migrate toward epistemic authority on evidence — possible only when commitments are recorded and outcomes can be scored.

A committed claim is trustworthy only to the extent of its committer’s authority weight in the relevant domain — and authority weight is worth nothing until it is committed. Commitment without standing is worthless; standing without commitment is worthless opinion.
