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.

“The culture wars will continue to be marked by both sides scoring an unrelenting series of own-goals, with the victory going to whoever can make their supporters shut up first.”

Scott Alexander, blog author 15 February 2018 Five More Years (Slate Star Codex)

The culture wars will continue with both sides scoring own-goals, victory going to whichever side first gets its supporters to shut up.

Mixed Partly true and partly false in roughly equal measure.

The second judge would not resolve this claim; the verdict shown is the first judge's.

What would count as true or false

This is judged over Feb 2018 to Feb 2023 and has two parts: (1) the culture wars continued and both sides kept making widely recognised self-defeating moves (own-goals); (2) outcomes went to whichever side got its more vocal supporters to quiet down first. TRUE if commentary and events over the period show both parts: own-goals by both sides were persistent, and the side that restrained its activists gained ground in observable outcomes such as elections, public opinion or policy. MIXED if part (1) is well supported but part (2) cannot be shown or is contradicted by mixed outcomes. MOSTLY FALSE if the culture wars continued but own-goals were plainly one-sided, or part (2) is clearly contradicted. FALSE if the culture wars visibly subsided, or the dynamic described was largely absent.

    “The result is that Republicans have gotten to fill this void with an image of Democrats as out-of-touch cultural extremists.”

Reasoning

Part (1) has reasonable support. The commentary shows Democrats making self-inflicted culture-war mistakes, such as "Defund the Police" being called political poison (E10, E11). It also shows a Republican one: Trump-endorsed challengers fared poorly and the expected "red wave" did not come (E8). Part (2) rests mainly on one sociologist's blog. It says Democrats tried to "course correct" and that running moderates won in 2022 (E3, E7), and NBC reports that many in the party saw Adams' primary win as a sign voters were done with anti-police rhetoric (E9). That is not enough to show a consistent pattern where the side that quieted its activists won. Scott Alexander's own grading (E1) says "all of this is basically true" but is not independent, and the quoted text does not name this specific claim.
