Social norms function as incentive-shifters against free-rider defection in collective action

Evidence

Social norms remain one of the most powerful tools we have for fighting against the forces that want to further carve out the blank space. Humans have always used norms to rebalance social rewards and punishments, ensuring that self-interest doesn’t erode the collective good. This means we can use norms to reward invention and discourage cynical, exploitative uses of culture. Consider the Mafia’s omertà—a code of silence designed to prevent snitching. By threatening dishonor (and worse) to anyone who squeals, the omertà shifts the incentives of the classic prisoner’s dilemma, ensuring nobody talks. — W. David Marx, Blank Space, 855
