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.
Pluralism in economics
The pluralism in economics movement is a campaign to change the teaching and research in economics towards more openness in its approaches, topics and standpoints it considers. The goal of the movement is to "...reinvigorate the discipline ... [and bring] economics back into the service of society". Some have argued that economics had greater scientific pluralism in the past compared to the monist approach that is prevalent today. Pluralism encourages the inclusion of a wide variety of neoclassical and heterodox economic theories—including classical, Post-Keynesian, institutional, ecological, evolutionary, feminist, Marxist, and Austrian economics, stating that "each tradition of thought adds something unique and valuable to economic scholarship".
