Document Summary

Local competition individuals interact + compete with the same partners: fitness between partners is relative and zero-sum my success = failure, vice versa, decreases cooperation. Global competition individuals interact with a subset of partners, and compete more broadly: fitness between partners is absolute and nonzero-sum we can both succeed together. Priso(cid:374)er"s dile(cid:373)(cid:373)a as competition goes from global local, the instability of tft increases. In local competition, i have no incentive to cooperate with my partner: local: participants only interact and compete within subgroups, global: participants interact within subgroups, but compete with everyone, cooperation almost doubles with global competition vs local competition. Local increase self-interest demands, the better you do, the worse i do. Not passed down through teachers, higher powers, or derived from reason: ex. Reason serves moral intuition, rather than the other way around: ex. solve series of causal inference problems some are neutral, others polarizing.
