In-group favoritism, sometimes known as in-group–out-group bias, in-group bias, intergroup bias, or in-group preference, is a pattern of favoring members of one's in-group over out-group members. This can be expressed in evaluation of others, in allocation of resources, and in many other ways.
Intergroup bias is a preference for one's in-group over the out-group. Derived from the social identity approach to intergroup behaviour, the common ingroup identity model is rooted in the process of social categorization, or how people conceive of group boundaries. The model describes how intergroup bias can be reduced if members of different ...
An illustrative example of the way this phenomenon takes place can be demonstrated just by arbitrarily assigning a person to a distinct and objectively meaningless novel group; this alone is sufficient to create intergroup biases in which members of the perceiver's own group are preferentially favored.

Social identity is the portion of an individual's self-concept derived from perceived membership in a relevant social group. [1] [2]As originally formulated by social psychologists Henri Tajfel and John Turner in the 1970s and the 1980s, [3] social identity theory introduced the concept of a social identity as a way in which to explain intergroup behaviour.
The common ingroup identity model, first outlined in 1993, describes how recategorization can mitigate bias; intergroup contact theory, introduced five years later, describes how recategorization can be achieved. [4] [5] Under the contact hypothesis, intergroup contact under certain conditions will reduce intergroup prejudice.
In psychology and cognitive science, a memory bias is a cognitive bias that either enhances or impairs the recall of a memory (either the chances that the memory will be recalled at all, or the amount of time it takes for it to be recalled, or both), or that alters the content of a reported memory. There are many types of memory bias, including:
The tendency to favor one's own social group is called an ingroup bias, and it can be both explicit (conscious and controllable) and implicit (unconscious and instinctual). The realistic conflict theory, social identity theory, and optimal distinctiveness theory aim to explain the ingroup bias and its possible negative impacts on the outgroups.
Optimal distinctiveness theory was built upon and further extended the assumptions of social identity theory and other models that examine ingroup bias and favoritism. [1] [2] [7] Social identity theory, proposed by Tajfel and Turner in 1979, describes the psychological basis of such bias and discrimination.
