Authority Without a Wikipedia Page

Authority Without a Wikipedia Page
The question: do you need formal credentials — or a Wikipedia page — for an author to count as authoritative on YMYL topics? The strong version of this advice gatekeeps: no degree, no notability, no authority. The QRG does not say that.

Per the guidelines, expertise is topic-dependent and can be everyday. The document gives explicit examples: people with lived experience of an illness, or hobbyists with deep practical knowledge, can be expert sources for certain questions. Formal credentials matter most for what the QRG calls clear YMYL medical, legal, or financial advice — not for the full breadth of consequential topics.

Two distinctions the advice collapses:
— Credentials vs. reputation. The QRG asks raters to find reputation from independent sources; a credential is one input, not the requirement.
— Notability vs. expertise. A Wikipedia page is evidence of notability, which is rarer than competence. Most legitimate experts have no encyclopedia entry.

Counter-evidence: in high-stakes medical results, credentialed authors are over-represented. True — but this reflects the topic's harm potential, where the QRG genuinely raises the bar, not a universal rule.

Caveat: 'everyday expertise counts' is not a license to publish unsourced medical claims. For the narrow band of clear YMYL advice, the guidelines do expect formal qualification or strong institutional backing.

What we still don't know: how ranking systems operationalize 'everyday expertise' for entities with no formal credential trail — the signal is easy to state and hard to detect at scale.
