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.
State (polity)
Pluralists view society as a collection of individuals and groups, who are competing for political power. They then view the state as a neutral body that simply enacts the will of whichever groups dominate the electoral process. Within the pluralist tradition, Robert Dahl developed the theory of the state as a neutral arena for contending interests or its agencies as simply another set of interest groups. With power competitively arranged in society, state policy is a product of recurrent bargaining. Although pluralism recognizes the existence of inequality, it asserts that all groups have an opportunity to pressure the state. The pluralist approach suggests that the modern democratic state's actions are the result of pressures applied by a variety of organized interests. Dahl called this kind of state a polyarchy.
