The research, plainly
George Miller's 'The Magical Number Seven' established working memory's brutal budget — roughly seven items, and for meaningful retention, far fewer. Chunking — grouping items into a handful of bundles — is how anything complex survives in a human head.
The receipt: Miller, 1956
What it means for events
The agenda with ten priorities has none. Three takeaways per session, three moments per event, three-part frameworks — the discipline isn't dumbing down; it's packaging for the only container the audience brought: a small one.
Where to run it
Content architecture
Every session answers: what are the three things? If the speaker can't say, the audience certainly can't.
Event messaging
One theme, three pillars, everywhere — signage, opener, closer, follow-up. Repetition of the chunk builds the memory.
Frameworks
Name your three-part model and it travels: attendees can carry 'Signal, Shift, Proof' into a meeting; they cannot carry a slide of twelve arrows.
