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.
William E. Connolly
Over the course of the last four decades Connolly has helped to remake the theory of pluralism. Connolly challenges older theories of pluralism by arguing for pluralization as a goal rather than as a state of affairs. Connolly's argument for the "multiplication of factions" follows James Madison's logic in engaging groups, constituencies, and voters at both the micro and macro level. Essentially, he has shifted the theory from a conservative theory of order, to a progressive theory of democratic contestation and engagement. By engaging Nietzsche and Foucault, Connolly explores the nature of democratic contestation and its relation to pluralism. A more comprehensive look on pluralism can be found in the work "Pluralism".
