1 supported 0 partly supported 0 contradicted 2 not checkable as stated how the 3 claims stand · each chip opens the sources
3 assertions · 1 opinion · 7 insights · 4 disclosures · every statement was checked. The predictions and assertions are the 3 claims: statements the public record can support or contradict. 1 is resolved, and 2 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 Jack argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.
How they sound: speaking style how? →
263 words/min while actually speaking · 4.2 um and uh per 1k words
No argument clarity score for Jack Groetzinger: 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 30 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 4,273 words across 1 episode, but every recording we have of Jack Groetzinger 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 →
