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.
Religious pluralism
Religious pluralism can be defined as "respecting the otherness of others". Freedom of religion encompasses all religions acting within the law in a particular region. Exclusivist religions teach that theirs is the only way to salvation and to religious truth, and some of them would even argue that it is necessary to suppress the falsehoods taught by other religions. Some Protestant sects argue fiercely against Roman Catholicism, and fundamentalist Christians of all kinds teach that religious practices like those of Paganism and witchcraft are pernicious. This was a common historical attitude prior to the Enlightenment, and has appeared as governmental policy into the present day under systems like Afghanistan's Taliban regime, which destroyed the ancient Buddhas of Bamyan.
