14 not checkable as stated how the 14 claims stand · each chip opens the sources

7 predictions · 7 assertions · 8 opinions · 18 insights · 11 disclosures · every statement was checked. The predictions and assertions are the 14 claims: statements the public record can support or contradict. 0 are resolved, and 14 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.

This is a score against a rubric. It is not a rank. Every host question → answer exchange is scored with names hidden on directness, coherence, precision and compression, 1–5 each, on meaning alone: disfluencies are ignored, and only raw unedited episodes count.

How they sound: speaking style how? →

240 words/min while actually speaking · 10.2 um and uh per 1k words · 9.2 false starts per 1k · 26.3% of pauses land inside a clause

Measured by listening to the audio itself: 9,506 words across 2 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.
