The Evolution of Trust.

The Evolution of Trust is Nicky Case’s playable explanation of cooperation and game theory. You choose between cooperating and cheating, then explore repeated encounters, different strategies and populations. The small games make assumptions visible: the payoff table, the number of encounters and mistakes can change the outcome. Use the controls as experiments, and read what each model holds fixed before generalizing from it.

Start with the payoff table

A single cooperate-or-cheat choice has a defined result for both participants. Read those values before judging a strategy by its label. The result of one encounter and the total across repeated encounters answer different questions. Keep both in view when the explanation introduces strategies with a memory of previous moves.

Repeat encounters before drawing a conclusion

The project’s sequence explores what changes when players meet more than once. An action can influence a later response, so a successful one-round choice need not produce the same advantage over a longer run. Compare runs under the same settings before attributing a difference to a strategy alone.

Keep the model’s limits visible

This is an interactive model, with explicit payoffs and rules that simplify social decisions. Use its experiments to understand those assumptions and how outcomes depend on them. It does not measure the trustworthiness of a real person or provide a universal rule for relationships. Third-party sound credits also remain separate from the public-domain original artwork.

A FEW USEFUL ANSWERS

Before the next click.

Is it an online multiplayer game?

Its main experience is a sequence of interactive game-theory experiments, not matchmaking with human opponents.

Can I change assumptions?

Later experiments expose model settings. Read the active controls and compare one change at a time.
