Conformity involves the changing of one’s attitudes, opinions, or behaviours. It causes sound-minded individuals to go against their best judgement, to engage in behaviour which they usually would not engage in, even accept and welcome an idea they internally disagree with, all in order to not be a deviant from the group.
