Robert Axelrod (born 1943) is an American political scientist and professor at the University of Michigan, best known for his landmark work on the evolution of cooperation using game theory and computer tournaments. His research demonstrated that cooperative strategies can emerge and persist among self-interested agents without central authority, influencing fields from political science and evolutionary biology to economics and philosophy.
Organized iterated Prisoner's Dilemma tournaments showing Tit-for-Tat as a robust cooperative strategy
Authored 'The Evolution of Cooperation' (1984), a foundational text in evolutionary game theory
Demonstrated that cooperation can evolve among egoists without central enforcement
Contributed formal analysis of replicator dynamics and their failure to guarantee convergence to evolutionarily stable states
