Standing — what the evidence certainty means
Established≥ 85%Strong, consistent evidence. Unlikely to change.
Likely65–84%Well supported, with some gaps or indirect evidence.
Uncertain40–64%Mixed or limited evidence. Genuinely open.
Doubtful15–39%Little support; the weight of evidence leans against it.
Refuted< 15%The evidence contradicts it — confidently false as stated.
