Episode notes
Scarcity Taps An Evolutionary Trigger
- Scarcity feels valuable because humans evolved to hoard rare resources for survival.
- Explicitly stating an end date or scarcity can significantly increase behaviour, like 36% more likely to see a movie.
Make Scarcity Specific And Novel
- Apply scarcity creatively beyond 'only X left' copy to regain novelty and impact.
- Tell customers when something will stop (e.g., end date) or limit per-person amounts to boost urgency.
Ownership Increases Value And Completion
- Feeling ownership increases perceived value (endowment/IKEA effect).
- Giving a head start or involving customers in creation boosts completion and loyalty, like pre-stamped loyalty cards driving 65% higher completion.
