Multiple layers of in-groups and out-groups in an American football stadium:
  • People in this stadium form an in-group of American football fans and professionals vs. those who are not fans of the sport.
  • Fans in attendance at the stadium vs. people spectating the match via external means, e.g. television/radio coverage.
  • Fans and professionals affiliated with one team vs. those affiliated with the opposing team.
  • Professionals on the field (players, officials, coaches, mascots and cheerleaders) vs. the paying customers in the stands who are denied access to the facility's secure nucleus except by invitation from a high-status individual.
  • Ranks of the wealthy ownership and their senior executive staff, with access to private box suites vs. high-priced talent.
  • Technical staff involved in facilities maintenance and operations vs. sporting staff (referees, timekeepers, statisticians and in-game adjudicators).
  • Media with organizational endorsement and affiliation who enjoy special player access to one team vs. non-affiliated media.

In social psychology and sociology, an in-group is a social group to which a person psychologically identifies as being a member. By contrast, an out-group is a social group with which an individual does not identify. People may for example identify with their peer group, family, community, sports team, political party, gender, sexual orientation, religion, or nation. It has been found that the psychological membership of social groups and categories is associated with a wide variety of phenomena.

The terminology was made popular by Henri Tajfel and colleagues beginning in the 1970s during his work in formulating social identity theory. The significance of in-group and out-group categorization was identified using a method called the minimal group paradigm. Tajfel and colleagues found that people can form self-preferencing in-groups within a matter of minutes and that such groups can form even on the basis of completely arbitrary and invented discriminatory characteristics, such as preferences for certain paintings.[1][2][3][4]

In neurology, there is an established literature[5] about the innate propensity of the human brain to divide the world into us and them valence categories, where the exact membership of the in-group and out-group are socially contingent (hence vulnerable to the instruments of propaganda), and the intensity exists along a spectrum from mild to complete dehumanization of the "othered" group (such as through pseudospeciation).

Associated phenomena

[edit]

The psychological categorization of people into in-group and out-group members is associated with a variety of phenomena. The following examples have all received a great deal of academic attention.

In-group favoritism

[edit]
See also: In-group favoritism; Closure (sociology); and You are either with us, or against us

This refers to the fact that under certain conditions, people will prefer and have affinity for one's in-group over the out-group, or anyone viewed as outside the in-group. This can be expressed in one's evaluation of others, linking, allocation of resources, and many other ways.[6] How we perceive the actions of others are also affected by in-group favoritism. People may perceive the same action very differently depending on whether the action was executed by a member of the same group or a member of a different group.[7] In fact, people tend to evaluate actions of their own group or team members much more favorably than those of outgroup members.[7] 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.[8] This phenomenon was demonstrated in an empirical study conducted by Molenberghs and colleagues in 2013.[7] In the study, participants were arbitrarily divided into two teams where they watched videos of individuals of competing teams and individuals from their own team perform hand actions. Participants were then asked to judge the speed of the hand movements.[7] On average participants judged members of their own teams to be faster, although the hand movements were the exact same speed across the board. Similarly, Hastorf and Cantril conducted a pioneering study in 1954, where students of both Princeton and Dartmouth viewed a contentious football game between their two teams.[9] Although they had watched the same motion picture of the game, their versions of what transpired were so starkly different it appeared as though they had watched two totally different games.[9]

Neural mechanisms of in-group favoritism and out-group bias

[edit]

Some may wonder why in-group favoritism takes place, even in arbitrarily assigned groups where group members have nothing in common other than the group to which they were assigned. Research points to unconscious decision-making processes that takes place at the neurological level, where in-group favoritism and out-group bias occurs very early in perception. This process can begin by simply viewing a person's face.[10] Research indicates that individuals are faster and more accurate at recognizing faces of ingroup vs. outgroup members.[11] For example, researchers in a cross-race recognition study recorded blood oxygenation level-dependent signal (BOLD) activity from black and white participants while they viewed and attempted to remember pictures of unfamiliar black faces, white faces and objects.[12] They found that participants in this study exhibited greater activity in the fusiform face area (FFA), an area of the fusiform gyrus located in the inferior temporal cortex of the brain linked to object and face recognition, when viewing same race faces compared to other race faces.[12] Lower activity in the FFA reflects a failure to encode outgroup members at the individual level rather than the categorical level, which comes at the expense of encoding individuating information.[13][14][15] This suggests out-group or unfamiliar faces may not be "faces" with the same intensity as in-group faces.[16] Prior research has also shown that the devaluation and dehumanization of outgroup members is exacerbated when the initial encoding and configural processing of an outgroup face is impeded.[17] So not only does this initial encoding process dehumanize outgroup members, it also contributes to a homogeneity effect, whereby outgroup members are perceived as more similar to each other than ingroup members.[18]

Group homogeneity

[edit]
Main article: Outgroup homogeneity

Categorization of people into social groups increases the perception that group members are similar to one another. An outcome of this is the out-group homogeneity effect. This refers to the perception of members of an out-group as being homogenous, while members of one's in-group are perceived as being diverse, e.g. "they are alike; we are diverse".[19][20] This is especially likely to occur in regard to negative characteristics. Under certain conditions, in-group members can be perceived as being similar to one another in regard to positive characteristics. This effect is called in-group homogeneity.[21]

Out-group derogation

[edit]

Discrimination between in-groups and out-groups is a matter of favoritism towards an in-group and the absence of equivalent favoritism towards an out-group.[22] Out-group derogation is the phenomenon in which an out-group is perceived as being threatening to the members of an in-group.[23] This phenomenon often accompanies in-group favoritism, as it requires one to have an affinity towards their in-group. Some research suggests that out-group derogation occurs when an out-group is perceived as blocking or hindering the goals of an in-group. It has also been argued that out-group derogation is a natural consequence of the categorization process.[24]

Social influence

[edit]
Main article: Social influence

People have been shown to be differentially influenced by in-group members. That is, under conditions where group categorization is psychologically salient, people will shift their beliefs in line with in-group social norms.

Group polarization

[edit]
Main article: Group polarization

This generally refers to the tendency of groups to make decisions that are more extreme than the initial inclination of its members, although polarization toward the most central beliefs has also been observed. It has been shown that this effect is related to a psychologically salient in-group and outgroup categorization.

Postulated role in human evolution

[edit]

In evolutionary psychology, in-group favoritism is seen as an evolved mechanism selected for the advantages of coalition affiliation.[25] It has been argued that characteristics such as gender and ethnicity are inflexible or even essential features of such systems.[26][27] However, there is evidence that elements of favoritism are flexible in that they can be erased by changes in social categorization.[28] One study in the field of behavioural genetics suggests that biological mechanisms may exist which favor a coexistence of both flexible and essentialist systems.[29]
