The research, plainly
Elizabeth Newton's tapper study: people tapped famous songs and predicted listeners would name half of them. Listeners got about one in forty. The tune playing in the tapper's head was inaudible to everyone else — and the tapper couldn't believe it.
The receipt: Newton, 1990
What it means for events
Every expert on your stage hears the song. The audience hears tapping. Speaker prep isn't slide polish — it's systematically rebuilding the talk from what the room knows, not from what the speaker knows.
Where to run it
Speaker coaching
Open every prep session with one question: 'What does this audience know on minute zero?' Build forward from that, ruthlessly.
Demo design
The demo that thrills the product team confuses the buyer. Script it for the person seeing it first, not the person who built it.
Internal events
Leadership's strategy deck is written in leadership's shorthand. Translate before broadcasting — the org can't follow taps.
