2 predictions · 37 assertions · 1 opinion · 5 insights · 8 disclosures · 1 what if · every statement was checked. The predictions and assertions are the 39 claims: statements the public record can support or contradict. 28 are resolved, and 11 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 JoeBen 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

Assertion Supported

Expressed certainty vs assessment result

none yet certainty 1
none yet certainty 2
none yet certainty 3
89% 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

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 JoeBen Bevirt on measured tape to publish a rate. This says nothing about how they speak.
