Repeated Game, Reputation
The Boundary-Setting Choice
The Boundary-Setting Choice is a Repeated Game and Reputation scenario. The core lesson: People respect the boundaries you enforce, not the ones you announce. A friend regularly asks for favors, help moving, airport rides, last-minute babysitting, but the reciprocity has been one-sided for years. You've mentioned it twice. DecisionPlay maps the players, payoffs, and equilibrium dynamics that shape how this situation typically resolves.
The situation
A friend regularly asks for favors, help moving, airport rides, last-minute babysitting, but the reciprocity has been one-sided for years. You've mentioned it twice. They've asked again.
Background
In repeated social games, what you do matters more than what you say. Announced boundaries without enforcement teach the other person that your stated limits are not real limits. The cost of enforcing a boundary is real in the short term; the cost of never enforcing it compounds over time.
What this reveals
Announced boundaries are not boundaries
The word 'boundary' has become so common that people confuse announcing a limit with enforcing one. In a repeated social game, your pattern of behavior is the real message, not what you say you'll do. A friend who has learned that your stated limits don't hold will continue to test them. A friend who has experienced you enforcing a limit once usually stops testing.
How to counter it: The next time you catch yourself saying 'I really need to set a boundary with X,' ask: what would it look like to actually enforce it? Then do that thing, once, and observe what changes.
A question to sit with
What's a boundary you've announced repeatedly but never actually enforced? What would enforcing it look like?
