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.

As John Hick put it, pluralism is the belief that no one religion has a monopoly of the truth or of the life that leads to salvation. In the poetic words of the great Sufi, Rumi, speaking of the religions of the world, "The lamps are different but the Light is the same; it comes from beyond" (Rumi: Poet and Mystic, trans. R.A. Nicholson, London and Boston: Unwin, p. 166).
