Group norms refer to the rules and expectations governing the behavior of members of the group. For example, within a corporate setting, individual group members are expected to dress and act professionally. They should not wear overly casual clothes, engage in illegal behavior, drink alcohol, or behave in explicitly sexual or violent ways. They are expected to display a strong work ethic. In contrast, in adolescent street gangs, group members are expected to show unquestionable loyalty, present themselves as tough and ready for violence, and show little deference to conventional authority.
