207 predictions · 379 assertions · 186 opinions · 276 insights · 60 disclosures · 11 what ifs · every statement was checked. The predictions and assertions are the 586 claims: statements the public record can support or contradict. 234 are resolved, 18 are not yet assessed, and 334 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.

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

How they sound: speaking style how? →
324 words/min while actually speaking · 30.7 um and uh per 1k words · 39.2 false starts per 1k · 26.8% of pauses land inside a clause
Um and uh per 1,000 words, year by year. Hover a point for the year's tape.
Measured by listening to the audio itself: 607,998 words across 77 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.
