Stereotypes are biased preconceived notions about how people from certain groups will behave. They are influenced by parents and developed through categorization of people. While stereotypes are often negative, some can be positive like saying French people are good cooks. Stereotypes are not always about minorities and can exist within one's own group. They also change over time and are not always entirely false despite sometimes being exaggerations. The document addresses how youth culture can be positively or negatively stereotyped, such as with the London riots where youth were largely blamed by the media.
