Conformity is the act of matching attitudes, beliefs, and behaviors to group norms or politics. Norms are implicit, specific rules, shared by a group of individuals, that guide their interactions with others. People often choose to conform to society rather than to pursue personal desires because it is often easier to follow the path others have made already, rather than creating a new one. This tendency to conform occurs in small groups and/or society as a whole, and may result from subtle unconscious influences (predisposed state of mind), 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.

People often conform from a desire for security within a group—typically a group of a similar age, culture, religion, or educational status. This is often referred to as groupthink: a pattern of thought characterized by self-deception, forced manufacture of consent, and conformity to group values and ethics, which ignores realistic appraisal of other courses of action. Unwillingness to conform carries the risk of social rejection. Conformity is often associated with adolescence and youth culture, but strongly affects humans of all ages.
