Heuristic
Weight evidence by traceability, not popularity
Popularity is a retrieval signal, not a reliability model.
When it fits
- A verification workflow ranks sources mainly by frequency, search position or the number of pages agreeing.
When to avoid it
- Institutional status is not immunity from error; strong provenance improves accountability and traceability, not infallibility.
Why it matters
Give more weight to evidence with clear origin, methods, accountability and correction mechanisms. Reduce weight when origin is obscure, circular or synthetic. Keep contrary high-quality evidence visible even if fewer pages mention it. Use provenance as one dimension of source quality, not as a permanent authority score.
An example
Prefer an official specification and test result over fifty SEO pages repeating an undocumented configuration claim.
Check your result
Source ranking can be explained through provenance and method rather than page count alone.
Keep this limit in mind
- Institutional status is not immunity from error; strong provenance improves accountability and traceability, not infallibility.
Evidence and sources
The 2026 framework recommends weighting verification evidence by traceable origin, source credibility and institutional accountability rather than treating all retrieved sources as equally reliable.
Credibility signals can themselves be imperfect and should not become a permanent whitelist that blocks contrary evidence.
