25 assertions · 3 opinions · 11 insights · 6 disclosures · every statement was checked. The predictions and assertions are the 25 claims: statements the public record can support or contradict. 13 are resolved, 2 are not yet assessed, and 10 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 Sir 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
Dyson: Lloyds Bank lent Dyson £600,000 to launch manufacturing
“Whereas I went to a clearing bank, Lloyds Bank, and by some miracle, they agreed to lend me 600,000 pounds.”

Expressed certainty vs assessment result

none yet certainty 1
none yet certainty 2
75% certainty 3
85% 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 Sir James Dyson on measured tape to publish a rate. This says nothing about how they speak.

Dyson: Vacuum makers rejected bagless cyclone to protect paper bag profits
“And one or two of them said they actually rather like selling paper bags. It's like, you know, Gillette selling a razor blade. They can make a lot of money out of bags. So, essentially, they were curious, but didn't want to license it.”
