4 supported 1 partly supported 1 contradicted how the 6 claims stand · each chip opens the sources
6 assertions · 2 opinions · 7 insights · every statement was checked. The predictions and assertions are the 6 claims: statements the public record can support or contradict. 6 are resolved. 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 Geoff 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

No argument clarity score for Geoff Ralston: 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. Their coarse estimate from 24 exchanges on the produced feed is ≈4.5/5, shown at half point precision because the sample is small and produced tape scores higher.
Measured by listening to 5,025 words across 1 episode, but every recording we have of Geoff Ralston is the aired feed, and an editor cleaned that audio before release. Some of the hesitation was cut before we ever heard it, so read these as floors: the true rates are at least this high. These are measurements of speaking style, not scores. How it's measured →
