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.
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".
