Propinquity

People build relationships with whoever they keep ending up next to.

The research, plainly

Festinger, Schachter, and Back mapped friendships in MIT student housing and found proximity was destiny: neighbors became friends, people near stairwells knew everyone, and a few extra feet of distance measurably cut connection. Repeated accidental contact is how relationships actually start.

The receipt: Festinger et al., 1950

What it means for events

Stop hoping networking happens and start engineering collision. Who sits near whom, which cohorts share rooms and hotel floors, where the coffee forces lingering — proximity design is relationship design with a floor plan.

Where to run it

Seating strategy

Same tables across multiple sessions. Familiarity needs repetition, and repetition needs assignment.

Venue layout

One shared coffee point beats four convenient ones — inconvenience that causes collision is a feature.

Multi-day events

Cohort hotels and shared shuttles quietly do more networking than the networking reception.

Seen in the wild

Pixar's building was famously designed around a central atrium to force cross-team collisions, and MIT's legendary Building 20 bred breakthroughs from cramped adjacency. Both are propinquity used as innovation strategy — events can rent the same effect by the day.
