Pluralistic ignorance
In social psychology, pluralistic ignorance is a situation in which a majority of group members privately reject a norm, but go along with it because they incorrectly assume that most others accept it. This is also described as "no one believes, but everyone thinks that everyone believes". In short, pluralistic ignorance is a bias about a social group, held by the members of that social group.
The Book of Animal Ignorance
The Book of Animal Ignorance is the second title in a series of books based on the intellectual British panel game "QI", written by series-creator John Lloyd and head-researcher John Mitchinson. It is a trivia book, consisting largely of little-known facts about various animals, alongside factual corrections to "other" pieces of supposedly "well-known" trivia that, although widely believed, are not always accurate. It is a sequel to "The Book of General Ignorance".
