1 assertion · 3 opinions · 19 insights · 1 disclosure · every statement was checked. The predictions and assertion are the 1 claim: statements the public record can support or contradict. 0 are resolved, and 1 names 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 John 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? →

244 words/min while actually speaking · 0.7 um and uh per 1k words

No argument clarity score for John McMahon: 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. Their coarse estimate from 24 exchanges on the produced feed is ≈4.5/5, shown at half point precision because the sample is small and produced tape scores higher.

Measured by listening to 9,682 words across 1 episode, but every recording we have of John McMahon is the aired feed, and an editor cleaned that audio before release. Some of the hesitation was cut before we ever heard it, so read these as floors: the true rates are at least this high. These are measurements of speaking style, not scores. How it's measured →

McMahon: Win-loss reports are useless when sales teams lack core skills
“Why would I care, as an example, about somebody's win-loss reports when your sales force sucks? I'm trying to change your sales force. Why would I look at the win-loss reports when people really don't know why they won and certainly don't know why they lost?”
