A stereotype is a generalized perception of first impressions: behaviors presumed by a group of people judging with the eyes, criticizing ones outer appearance (or a population in general) to be associated with another specific group. Stereotypes, therefore, can instigate prejudice and false assumptions about entire groups of people, including the members of different ethnic groups, social classes, religious orders, the opposite sex, etc. A stereotype can be a conventional and oversimplified conception, opinion, or image, based on the assumption that there are attributes that members of the “other group” have in common. Stereotypes are sometimes formed by a previous illusory correlation, a false association between two variables that are loosely correlated if correlated at all. Though generally viewed as negative perceptions, stereotypes may be either positive or negative in tone.
