Pluralistic Ignorance Плюралістичне невігластво (ua)
a phenomenon of people having a false impression of what others think about various matters. The phenomenon occurs when people have an incorrect belief about the preferences of the members of a group they belong to or aspire to be part of. It may occur in a situation of information deficit – lack of communication between members of a group, when we have an impression that other members know better than us and are able to use substantive arguments in discussion. In this situation we rely on ‘their opinions’, even though those opinions do not actually exist.
