"No one is more concerned with social norms than teenagers," explains psychologist Dominique Berger. At school, teenagers blend into a "clique" to which they belong. Those who remain on the outside run the risk of being stigmatized. By positioning themselves as role models, adults have a major role to play in combating the stigmatization of young people by their peers. Furthermore, it is important not to overreact to the situation: the vast majority of teenagers do not stigmatize others any more than they themselves are stigmatized.
