The research, plainly
Hedwig von Restorff showed in 1933 that an isolated, distinctive item in a list — one red word among black — is recalled far better than its uniform neighbors. Distinctiveness earns memory; sameness forfeits it.

What it means for events
Your event competes inside a list: the attendee's season of near-identical conferences. The one that breaks pattern — in format, in venue, in a single unforgettable choice — is the one that survives recall. Different isn't decoration; it's the memory strategy.
Where to run it
Event positioning
Audit the category's sameness and break exactly one expectation loudly: the venue, the format, the length, the opening.
Agenda design
One session that looks nothing like the others — no slides, different room, different rules. It will be the one they cite.
Sponsorship & booths
In a hall of demo stations, the booth doing literally anything else wins the memory war before lunch.
