The most-watched TED talk scores 6/10 for confidence. Early nervousness, pacing too fast, and a Wright Brothers tangent that nearly derails it. The idea carries the talk.

Confidence 5, Impact 10. The Jobs Paradox. He read from a script the entire time. His flat delivery on "it was devastating" scored congruence 5. Yet the Death segment at 8:55 hits 7/9/8 as monotone becomes accidental authenticity.

85 filler words. 4/10 on confidence in a talk about confidence. But her personal narrative climax at 17:29? A 9/9/9. That moment alone makes the entire talk.

45 filler words. But the Gillian Lynne story at 15:04 is a masterclass. Flat in the analytical sections, then suddenly electric. Comedy timing masks genuine craft underneath.

The Performative Paradox. A speaking coach whose technique is so polished it becomes visible. Highest engagement of any speaker (9), but rehearsal artifacts drag congruence to 7. His gestures sometimes arrive before his words.

Strong engagement, weak congruence. The product demo lights up the room (8/10 engagement), but rehearsed confidence collapses when sharks push back. The gap between polished pitch and genuine conviction becomes visible under pressure.
