4 predictions · 22 assertions · 2 opinions · 16 insights · 2 disclosures · every statement was checked. The predictions and assertions are the 26 claims: statements the public record can support or contradict. 15 are resolved, and 11 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.

How they sound: speaking style how? →

286 words/min while actually speaking · 17 um and uh per 1k words

No argument clarity score for Sean Duffy: no 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: 10,222 words across 3 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.
