Conformity

Conformity is the adjustment of behavior or beliefs to align with group expectations. It can arise from a desire to be accepted or from treating others as sources of information.

Normative social influence: Influence arising from the desire for acceptance or to avoid social rejection. It explains conformity motivated by fitting in, even when private beliefs remain unchanged.
Compliance (psychology): A public change in behavior in response to a direct request, without necessarily changing private belief. Compliance can look like conformity, but it follows a request rather than group expectations alone.
Independence (social psychology): Resistance to social influence when forming or expressing a judgment or behavior. It names the alternative to aligning one's response with the group's position.
Groupthink: A decision-making failure in which pressure for group agreement undermines critical evaluation. Conformity can suppress doubts that a group needs to make sound decisions.
Informational social influence: Influence arising from treating other people as evidence about what is correct. It explains why uncertainty can make group judgments seem more reliable than one's own.
Obedience (psychology): Behavioral compliance with a command from an authority figure. Unlike conformity to a group, obedience centers on a directive from an authority.
Minority influence: The process by which a smaller group affects the beliefs or behavior of a majority. It reverses the usual direction of conformity, examining how dissenters can change group views.
Bystander effect: The tendency for individuals to be less likely to help when other people are present. People may follow the group's apparent inaction when deciding whether an emergency requires help.
Asch conformity experiments: Solomon Asch's studies in which participants judged line lengths after hearing unanimous group answers. The experiments showed that a unanimous majority can sway even an obvious perceptual judgment.
Social influence: The ways people affect one another's beliefs, feelings, and behavior. Conformity is one form of this broader process of interpersonal influence.
