What Is Stereotyping?

A stereotype is a held popular 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.
Theories on stereotypes
Different disciplines give different accounts of how stereotypes develop: Psychologists may focus on an individual's experience with groups, patterns of communication about those groups, and intergroup conflict. Pioneering psychologist William James cautioned psychologists themselves to be wary of their own stereotyping, in what he called the psychologist's fallacy. Sociologists focus on the relations among groups and the of different groups in a social structure. Psychoanalytically-oriented humanists have argued (e.g., Sander Gilman) that stereotypes, by definition, are representations
Joshua Aronson and Claude M. Steele have done research on the psychological effects of stereotyping, particularly its effect on African Americans and women.[9] They argue that psychological research has shown that competence is highly responsive to situation and interactions with others.[10] They cite, for example, a study which found that bogus feedback to college students dramatically affected their IQ test performance, and another in which students were either praised as very smart, congratulated on their hard work, or told that they scored high. The group praised as smart performed significantly worse than the others. They believe that there is an 'innate ability bias'. These effects are not just limited to minority groups. Mathematically competent white males, mostly math and engineering students, were asked to take a difficult math test. One group was told that this was being done to determine why Asians were scoring better. This group performed significantly worse than the control
