persisting cultures: pluralistic ignorance
pluralistic ignorance is the tendency for people to collectively misinterpret the thoughts that underlie other people’s’ behaviours (ex. Feeling like everyone enjoys drinking at campus parties when in reality some people don’t, but just don’t say anything because it would be socially undesirable to do so → leads others to create a false impression) → we’re influenced by what we believe people feel rather than by what they actually feel → allows cultural practices to persist even if the majority of people don’t actually agree with them (ex. Prohibition)
