The research, plainly
B.F. Skinner's operant conditioning work found variable-ratio reinforcement — rewards on an unpredictable schedule — produced the most persistent behavior of any pattern, far outlasting predictable payoffs. Uncertainty of reward, strangely, strengthens pursuit.

What it means for events
Guaranteed swag is priced in before it's received; unpredictable delight compounds. Random upgrades, surprise guests, mystery unlocks — a lean layer of genuine unpredictability keeps attendees leaning forward all day, checking, hoping, engaged.
Where to run it
Engagement mechanics
Random seat upgrades and surprise perks announced through the day — the checking behavior is the engagement.
Agenda design
One unannounced moment per event, reliably unreliable: attendees learn that anything might happen, so attention stays on.
Gamification
Prize draws beat point-buys — the raffle's uncertainty out-motivates the catalog's certainty at equal cost.
