The research, plainly
John Sweller's cognitive load theory established that working memory is small and fixed — effort spent on one demand is unavailable for another. Navigation is a demand: a confusing environment consumes the exact resources your content needs.

What it means for events
Nobody arrives at your keynote with a fresh brain if they spent twenty minutes lost in the venue. Confusion is a tax collected before you say hello — and it's paid again at every unclear transition. Signage a stranger can follow at walking speed is content strategy.
Where to run it
Arrival experience
Test the route as a first-timer: parking to seat, zero questions needed. Every asked-a-staffer moment is a design failure.
Multi-room events
Color, naming, and repetition — tracks that look like what they're called, maps at every decision point.
Virtual events
One link, one click, one obvious next step. Digital wayfinding fails at the exact same cost as physical.
