5 supported 0 partly supported 4 contradicted 1 not yet assessed 9 not checkable as stated how the 19 claims stand · each chip opens the sources
13 predictions · 6 assertions · 2 opinions · 9 insights · 1 disclosure · 2 what ifs · every statement was checked. The predictions and assertions are the 19 claims: statements the public record can support or contradict. 9 are resolved, 1 is not yet assessed, and 9 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 Dennis 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
Their most notable contradicted 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 Dennis Mortensen: 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 28 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 12,616 words across 3 episodes, but every recording we have of Dennis Mortensen 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 →
