Standing: what the evidence certainty means
Established≥ 85%Strong, consistent evidence. Unlikely to change.
Likely70–84%Well supported, with some gaps or indirect evidence.
Uncertain50–69%Mixed or limited evidence. Genuinely open.
Doubtful30–49%Little support; the weight of evidence leans against it.
Refuted< 30%The evidence contradicts it. Confidently false as stated.
A standing changes only when the score moves past a boundary by more than 4 points, the re-scoring noise floor; a score within 4 points of a boundary keeps its previous standing.
