775 claims collected, 234 researched, 81 resolved. Report of 4 November 2026, method 0.1.0+8bea457b.

Scores by kind of claim

Each kind of claim is scored on its own, out of 100: the share that held up, with the range it likely falls in. Fewer resolved claims give a wider range.

  • Factual claims

    Statements about the present or the past, checked against the record: did they hold up?

    80 72 88

    Medium confidence, 35 factual claims resolved. From 10 documents, 2014 to 2026; 15 documents sampled from 35 candidates found.

    Not scored: 46 unresolvable, 9 checkable only against their own records.

  • Predictions

    Statements about events outside the person's control, checked once they fell due: did they come true?

    70 62 78

    Medium confidence, 44 predictions resolved. From 7 documents, 2016 to 2025; 15 documents sampled from 35 candidates found.

    Not scored: 67 unresolvable, 10 checkable only against their own records. 19 more fall due later.

    Does not yet allow for how likely each prediction was when made.

  • Promises

    Commitments to the person's or organisation's own future action, with something to deliver: was it delivered?

    Insufficient record: 2 promises resolved, 5 needed for a score.

All types combined: 75 (likely 69 to 80, high confidence), from 79 claims: 35 factual claims, 44 predictions. It mixes kinds of claim in different proportions for different people, so compare people kind by kind.
