Ageism commonly denotes discrimination of the elderly, but recent studies suggest the need for a second definition in the form of youth discrimination. Society often treats adolescents and young adults according to stereotypes which portray young people as irresponsible, irresolute and untrustworthy. This hampers a recognition of the positive attributes of young people, and of the problems they face.
Adults often fear youth, often because of misrepresentative stereotypes, and their fear is reflected in policy decisions. Studies show, however, that it is more true to say that young people fear adults, that it is the young people who are the victims and the adults, the aggressors.
