Stereotype

In social psychology, a stereotype is a thought that can be adopted about specific types of individuals or certain ways of doing things. These thoughts or beliefs may or may not accurately reflect reality. However, this is only a fundamental psychological definition of a stereotype. Within psychology and spanning across other disciplines, there are different conceptualizations and theories of stereotyping that provide their own expanded definition. Some of these definitions share commonalities, though each one may also harbor unique aspects that may contradict the others.

The term stereotype derives from the Greek words στερεός (), "firm, solid" and τύπος (), impression, hence "solid impression on one or more idea/theory."

The term comes from the printing trade and was first adopted in 1798 by Firmin Didot to describe a printing plate that duplicated any typography. The duplicate printing plate, or the stereotype, is used for printing instead of the original.

Outside of printing, the first reference to "stereotype" was in 1850, as a noun that meant image perpetuated without change. However, it was not until 1922 that "stereotype" was first used in the modern psychological sense by American journalist Walter Lippmann in his work Public Opinion.

Stereotypes, prejudice, and discrimination are understood as related but different concepts. Stereotypes are regarded as the most cognitive component and often occurs without conscious awareness, whereas prejudice is the affective component of stereotyping and discrimination is one of the behavioral components of prejudicial reactions. In this tripartite view of intergroup attitudes, stereotypes reflect expectations and beliefs about the characteristics of members of groups perceived as different from one's own, prejudice represents the emotional response, and discrimination refers to actions.
