Another question for the distributed systems engineers here: what kind of computation would be required for a system of people to rigorously identify and disprove their myths? In order for Person A to efficiently disprove Myth X in Person B, Person A needs (1) to know that Person B believes Myth X; (2) to know and employ some action (such as a conversation) that will be effective; and (3) not have something better to do (opportunity cost).
