Nicky Case — The Evolution of Trust (2017)
An interactive web essay that animates the core findings of Robert Axelrod’s iterated Prisoner’s Dilemma research — particularly the conditions under which cooperative strategies (tit-for-tat, generous tit-for-tat) outcompete defective ones, and when they don’t. Through playable simulations, Case demonstrates how trust can evolve from pure self-interest given repeated interaction, sufficient memory, and appropriate payoff structures.
The essay also explores how communication errors, misreading of signals, and structural conditions (payoff ratios, shadow of the future, number of players) affect the stability of cooperative equilibria. The design is notable: the interactive format allows readers to develop genuine intuitions about the dynamics rather than merely reading about them.
For OM: Case’s essay represents the best-case presentation of coordination mechanism design — what the Moloch frame can achieve. OM’s Lovers’ Dilemma essay cites it precisely as the limit of that approach: these dynamics apply when parties are genuinely in a coordination game, but not when the problem is structural/ontological rather than coordinative.
