2 predictions · 15 assertions · 2 opinions · 5 insights · 5 disclosures · 1 what if · every statement was checked. The predictions and assertions are the 17 claims: statements the public record can support or contradict. 9 are resolved, and 8 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 Mateo 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
Jaramillo: Iron-air raw materials cost under $1/kWh versus $30/kWh for lithium
“You're starting with a raw cost of materials that's less than a dollar per kilowatt hour, right? This is as compared to, let's say, unprocessed minerals for lithium mine that sitting on a table is, you know, 30 bucks a kilowatt hour, something like that.”

Expressed certainty vs assessment result

none yet certainty 1
none yet certainty 2
none yet certainty 3
93% 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 Mateo Jaramillo on measured tape to publish a rate. This says nothing about how they speak.
