The record, in short
What the tape says about how Keller argues and how the claims held up. Everything they said, and everything said about them, is in the tabs below.
How they sound: speaking style how? →
274 words/min while actually speaking · 9.8 um and uh per 1k words
No argument clarity score for Keller Rinaudo Cliffton: no usable question→answer exchanges on raw tape (a fair score needs 8+). We do not score a sample that small. Roundtable and news formats yield far fewer direct exchanges than interviews.
Measured by listening to the audio itself: 4,081 words across 2 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.
