http://en.wikipedia.org/wiki/Stereotype
A
stereotype is a commonly held public belief about specific social groups, or types of individuals. The concepts of "stereotype" and "
prejudice" are often confused with many other different meanings. Stereotypes are standardized and simplified conceptions of groups, based on some prior assumptions.
Stereotypes are created based on some idea of abstract
familiarity. For example, the same
behavior or
trait being repeatedly observed by multiple witnesses over an extended period of time. For a stereotype to develop and 'stick' in the popular imagination, a stereotype cannot be completely false, and must have an element of
social recognition.
A stereotype can be deemed 'positive', or 'negative'. Concepts of
stereotype are rarely invoked in instances of positive stereotypes being held about a group. The moniker 'stereotype' is more likely to be deployed in relation to stereotypes deemed to be negative.
