# Idea People tend to be more rational in the following situations: When stakes are large: education, who to marry, what car/house to buy. When choices/decisions are repeated: people get closer and closer to [[optimization|optimality]] as they get more practice. When we make decisions as groups (e.g., [[crowdsourced fact-checking]]; but see [[groupthink]]). When choices are easy! [[Roger Myerson]] argued that [[rational behavior is the most important benchmark]]. # References
