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?

    73 67 79

    High confidence, 94 factual claims resolved. From 18 documents, 2008 to 2025; 19 documents sampled from 33 candidates found.

    Not scored: 65 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?

    Insufficient record: 0 predictions resolved, 5 needed for a score.

    Not scored: 11 unresolvable. 2 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: 0 promises resolved, 5 needed for a score.

    Not scored: 1 checkable only against their own records.
