14 predictions · 23 assertions · 7 opinions · 15 insights · 7 disclosures · every statement was checked. The predictions and assertions are the 37 claims: statements the public record can support or contradict. 24 are resolved, 4 are not yet assessed, and 9 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 Tomasz 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
Tunguz: Unstructured job interviews predict employee success only 8% of the time
“Unstructured interviews, which is when we interview people by asking just kind of the typical questions, can only predict success in about eight percent of the cases, which is far worse than a coin flip. And so what Adam Grant, who's a professor in this field,…”

Their most notable contradicted claim

Prediction Didn’t hold up
Tunguz: DeSantis will win the Republican primary over Trump
“I don't think so. I think, I bet DeSantis wins. I think it will be tough for him to circumnavigate all the legal troubles, and I wonder if the RNC doesn't get involved.”

Expressed certainty vs assessment result

none yet certainty 1
none yet certainty 2
50% certainty 3
64% 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

This is a score against a rubric. It is not a rank. Every host question → answer exchange is scored with names hidden on directness, coherence, precision and compression, 1–5 each, on meaning alone: disfluencies are ignored, and only raw unedited episodes count. This is the score that measures thought. Every scored exchange, scores shown → · The rubric and its checks →

How they sound: speaking style how? →

285 words/min while actually speaking · 14.2 um and uh per 1k words · 11.7 false starts per 1k · 35.4% of pauses land inside a clause

English is their second language (first language: Portuguese). These numbers measure fluency in English. They do not measure thought; the argument clarity score above is read from substance alone.

Measured by listening to the audio itself: 16,310 words across 3 episodes of raw-level tape, transcribed verbatim with every um and uh kept, each one attributed only where the alignment onto our timed stream is unambiguous. These are measurements of speaking style. We do not rank them: across this corpus, fluency and argument quality are nearly uncorrelated (ρ≈0.2), and smooth talking does not signal clear thinking.
