Endowment Effect Exercise
This role-playing game helps teams understand the endowment effect, where customers value a product more highly once they consider it theirs. Participants explore how to leverage this bias in marketing and sales strategies to enhance customer retention and satisfaction.
Learning Objective
Teams explore the endowment effect — how customers value something more once they feel they own it — and practise using psychological ownership ethically to deepen attachment.
How to Play
Setup
- Give half the room a small item or a simulated 'owned' product; give the other half only the option to acquire it.
- Ask owners to name a selling price and non-owners a buying price.
- Capture the predictable gap between the two on a shared board.
Rules of play
- Run the trade simulation and reveal the price gap created purely by ownership.
- Teams then design product or marketing moments that create a sense of ownership before purchase (trials, personalisation, configuration).
- Each design must distinguish genuine value from artificial lock-in.
- The room votes on which tactics build attachment without trapping the customer.
Debrief
- How large was the gap between owners' and non-owners' prices?
- Where does fostering ownership help the customer versus merely raising switching costs?
- Which moments in your journey could let customers 'own' the product sooner?
CX Principle Reinforced
The endowment effect means people demand more to give up something than they would pay to acquire it. Free trials, personalisation and configuration all work partly by triggering early psychological ownership.
Used ethically, ownership cues help customers experience real value sooner; used cynically, they become lock-in. The distinction is whether the customer would still choose you with no friction to leave.
