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?

  83 77 88

  High confidence, 79 factual claims resolved. From 17 documents, 2014 to 2026; 19 documents sampled from 35 candidates found.

  Not scored: 31 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?

  67 49 83

  Low confidence, 8 predictions resolved. From 6 documents, 2018 to 2026; 19 documents sampled from 35 candidates found.

  Not scored: 91 unresolvable. 60 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: 1 promise resolved, 5 needed for a score.

  Not scored: 3 not yet due.

All types combined: 81 (likely 76 to 86, high confidence), from 87 claims: 79 factual claims, 8 predictions. It mixes kinds of claim in different proportions for different people, so compare people kind by kind.
