The predictions and assertions are the 37 claims: statements the public record can support or contradict. 16 are resolved, 4 are not yet assessed, and 17 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.

none yet certainty 1
none yet certainty 2
100% certainty 3
61% certainty 4
100% 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

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. This is the score that measures thought. Every scored exchange, scores shown → · The rubric and its checks →

How they sound: speaking style how? →

292 words/min while actually speaking · 7.2 um and uh per 1k words · 13.5 false starts per 1k · 27.4% of pauses land inside a clause

English is their second language (first language: Polish). These numbers measure fluency in English. They do not measure thought; the argument clarity score above is read from substance alone.

Measured by listening to the audio itself: 16,198 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.
