This recent video makes the game theory of iterated prisoners' dilemma quite accessible. https://www.youtube.com/watch?v=mScpHTIi-kM The idea of repeating the game and seeing what is a more successful strategy over time seems related tovoting system metrics such as Bayesian Regret and Voting System Efficiency (VSE): given the strategic behavior of a voting method, what voting strategy should a faction adopt based on the previous behavior of other factions they might join with through a coalition (lower ranking)? And which voting methods reward more cooperative and generous voting strategies?
