Harmony (The Rare Good Game)

Harmony (The Rare Good Game) is a Harmony and Aligned Incentives scenario. The core lesson: Sometimes everyone's incentives align, and the only thing to do is notice.

DecisionPlay maps the players, payoffs, and equilibrium dynamics that shape how this situation typically resolves.

The situation

You and a colleague are working on a project where your success and their success are completely aligned. There's no trade-off. Every move that helps one of you helps the other. What do you do?

Background

Harmony games are the rarest and most underappreciated. Everyone's dominant strategy is cooperation, and cooperation is also the best outcome. The interesting thing is that people often don't recognize Harmony, importing Prisoner's Dilemma assumptions into situations where defection is not something either side would choose. The result: wasted energy on non-existent conflicts.

What this reveals

The cost of misreading Harmony as competition

When someone's success is genuinely aligned with yours, defensive posturing is pure waste. The antidote is to believe the alignment until you have concrete evidence otherwise.

How to counter it: When someone's success seems aligned with yours, believe it. Defensive posturing in Harmony games is pure waste, you're paying an insurance premium against a threat that doesn't exist.

A question to sit with

Where in your life are you treating a Harmony game like a Prisoner's Dilemma? What would change if you trusted the alignment?
