conformity

Conformity is the act of matching attitudes, beliefs, and behaviors to group norms. Norms are implicit, unsaid rules, shared by a group of individuals, that guide their interactions with others. This tendency to conform occurs in small groups and/or society as a whole, and may result from subtle unconscious influences, or direct and overt social pressure. Conformity can occur in the presence of others, or when an individual is alone. For example, people tend to follow social norms when eating or watching television, even when alone.
