13 predictions · 7 assertions · 5 opinions · 4 insights · 14 disclosures · every statement was checked. The predictions and assertions are the 20 claims: statements the public record can support or contradict. 6 are resolved, and 14 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.

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 Jack Clark on measured tape to publish a rate. This says nothing about how they speak.
