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?

    67 61 73

    High confidence, 94 factual claims resolved. From 11 documents, 1995 to 2026; 19 documents sampled from 30 candidates found.

    Not scored: 44 unresolvable, 17 checkable only against their own records.

  • Predictions

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

    60 44 76

    Low confidence, 11 predictions resolved. From 6 documents, 1995 to 2025; 19 documents sampled from 30 candidates found.

    Not scored: 41 unresolvable, 1 checkable only against their own records. 4 more fall due later.
