0 supported 2 partly supported 0 contradicted 5 not checkable as stated how the 7 claims stand · each chip opens the sources

7 assertions · 7 insights · 4 disclosures · 1 what if · every statement was checked. The predictions and assertions are the 7 claims: statements the public record can support or contradict. 2 are resolved, and 5 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 Jenny 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

none yet certainty 1
none yet certainty 2
50% certainty 3
50% certainty 4
none yet 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

How they sound: not measured why? →

We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Jenny Just on measured tape to publish a rate. This says nothing about how they speak.
