Evolutionary game theory studies how strategies evolve and change over time, unlike classical game theory which focuses on static strategies. Natural selection, not rational choice, drives the evolution of strategies in biological systems. Initially, defectors outcompete cooperators but repeated interactions allow cooperation to evolve through strategies like tit-for-tat and generous tit-for-tat. Indirect reciprocity through reputation systems also enables cooperation in larger groups where people do not interact repeatedly. The evolution of cooperation through reciprocity, reputation, and social norms is a defining feature of human societies.
Evolutionary game theory focuses on the dynamics of strategy change over time and how strategies evolve, whereas classical game theory focuses on static strategies.
In evolutionary game theory, players do not act rationally but strategies that survive over time are considered optimal.
Defection is often the optimal strategy in a single-shot game, but cooperation can evolve in repeated games through punishment of non-cooperation and reward of cooperation.
The tit for tat strategy, which is cooperative but also quick to retaliate against defectors, is often successful in repeated prisoner’s dilemma games.
Generous tit for tat, a more forgiving version of tit for tat, can be an evolutionary stable strategy in noisy environments.
Indirect reciprocity through reputation systems can enable cooperation in large societies where people only interact once.
Reputation systems favor cooperators who then have more opportunities and success.
Humans have mastered indirect reciprocity and developed social intelligence and institutions to a greater extent than other species.
Norms, guilt, and shame help enforce cooperation and good behavior in groups.
Socio-cultural institutions enable advanced forms of human cooperation.
