Pluralistic ignorance
Pluralistic ignorance can be contrasted with the false consensus effect. In pluralistic ignorance, people privately disdain but publicly support a norm (or a belief), while the false consensus effect causes people to wrongly assume that most people think like they do, while in reality most people do not think like they do (and express the disagreement openly). For instance, pluralistic ignorance may lead a student to drink alcohol excessively because she believes that everyone else does that, while in reality everyone else also wishes they could avoid binge drinking, but no one expresses that due to the fear of being ostracized. A false consensus for the same situation would mean that the student believes that most other people do not enjoy excessive drinking, while in fact most other people do enjoy that and openly express their opinion about it.
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".
