2 supported 1 partly supported 0 contradicted 2 not yet assessed 5 not checkable as stated how the 10 claims stand · each chip opens the sources
3 predictions · 7 assertions · 12 opinions · 20 insights · 7 disclosures · every statement was checked. The predictions and assertions are the 10 claims: statements the public record can support or contradict. 3 are resolved, 2 are not yet assessed, and 5 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 Marc argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.
Their most notable supported claim
Expressed certainty vs assessment result
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

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? →
347 words/min while actually speaking · 30.2 um and uh per 1k words · 36.6 false starts per 1k · 28.4% of pauses land inside a clause
Measured by listening to the audio itself: 16,529 words across 1 episode 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.
