3 predictions · 16 assertions · 8 opinions · 9 insights · 4 disclosures · 2 what ifs · every statement was checked. The predictions and assertions are the 19 claims: statements the public record can support or contradict. 9 are resolved, and 10 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

The record, in short

What the tape says about how Katherine argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.

50% certainty 3
79% certainty 4
50% certainty 5

weighted support: a fully supported claim counts one, a partly supported claim counts half. Each filled bar is clickable and opens exactly those claims; "none yet" means nothing said at that certainty level has resolved yet

No argument clarity score for Katherine Boyle: only 2 usable question→answer exchanges on raw tape (a fair score needs 8+). We do not score a sample that small. Roundtable and news formats yield far fewer direct exchanges than interviews.

Measured by listening to the audio itself: 30,704 words across 15 episodes of raw-level tape, transcribed verbatim with every um and uh kept, each one attributed only where the alignment onto our timed stream is unambiguous. These are measurements of speaking style. We do not rank them: across this corpus, fluency and argument quality are nearly uncorrelated (ρ≈0.2), and smooth talking does not signal clear thinking.
