Social identity theory

Social identity is the portion of an individual's self-concept derived from perceived membership in a relevant social group. As originally formulated by social psychologists Henri Tajfel and John Turner in the 1970s and the 1980s, social identity theory introduced the concept of a social identity as a way in which to explain intergroup behaviour. Social identity is the portion of an individual's self-concept derived from perceived membership in a relevant social group. As originally formulated by social psychologists Henri Tajfel and John Turner in the 1970s and the 1980s, social identity theory introduced the concept of a social identity as a way in which to explain intergroup behaviour. Social identity theory is described as a theory that predicts certain intergroup behaviours on the basis of perceived group status differences, the perceived legitimacy and stability of those status differences, and the perceived ability to move from one group to another. This contrasts with occasions where the term 'social identity theory' is used to refer to general theorizing about human social selves. Moreover, and although some researchers have treated it as such, social identity theory was never intended to be a general theory of social categorization. It was awareness of the limited scope of social identity theory that led John Turner and colleagues to develop a cousin theory in the form of self-categorization theory, which built on the insights of social identity theory to produce a more general account of self and group processes. The term social identity approach, or social identity perspective, is suggested for describing the joint contributions of both social identity theory and self-categorization theory. Social identity theory suggests that an organization can change individual behaviors if it can modify their self-identity or part of their self-concept that derives from the knowledge of, and emotional attachment to the group. Social identity theory states that social behavior will vary along a continuum between interpersonal behavior and intergroup behaviour. Completely interpersonal behaviour would be behaviour determined solely by the individual characteristics and interpersonal relationships that exists between only two people. Completely intergroup behaviour would be behaviour determined solely by the social category memberships that apply to more than two people. The authors of social identity theory state that purely interpersonal or purely intergroup behaviour is unlikely to be found in realistic social situations. Rather, behaviour is expected to be driven by a compromise between the two extremes. The cognitive nature of personal vs. social identities, and the relationship between them, is more fully developed in self-categorization theory. Social identity theory instead focuses on the social structural factors that will predict which end of the spectrum will most influence an individual's behaviour, along with the forms that that behavior may take. A key assumption in social identity theory is that individuals are intrinsically motivated to achieve positive distinctiveness. That is, individuals 'strive for a positive self-concept'. As individuals to varying degrees may be defined and informed by their respective social identities (as per the interpersonal-intergroup continuum) it is further derived in social identity theory that 'individuals strive to achieve or to maintain positive social identity'. The precise nature of this strive for positive self-concept is a matter of debate (see the self-esteem hypothesis). Both the interpersonal-intergroup continuum and the assumption of positive distinctiveness motivation arose as outcomes of the findings of minimal group studies. In particular, it was found that under certain conditions individuals would endorse resource distributions that would maximize the positive distinctiveness of an ingroup in contrast to an outgroup at the expense of personal self-interest. Building on the above components, social identity theory details a variety of strategies that may be invoked in order to achieve positive distinctiveness. The individual's choice of behaviour is posited to be dictated largely by the perceived intergroup relationship. In particular the choice of strategy is an outcome of the perceived permeability of group boundaries (e.g., whether a group member may pass from a low status group into a high status group), as well as the perceived stability and legitimacy of the intergroup status hierarchy. The self-enhancing strategies detailed in social identity theory are detailed below. Importantly, although these are viewed from the perspective of a low status group member, comparable behaviours may also be adopted by high status group members. It is predicted that under conditions where the group boundaries are considered permeable individuals are more likely to engage in individual mobility strategies. That is, individuals 'disassociate from the group and pursue individual goals designed to improve their personal lot rather than that of their ingroup'. Where group boundaries are considered impermeable, and where status relations are considered reasonably stable, individuals are predicted to engage in social creativity behaviours. Here, low-status ingroup members are still able to increase their positive distinctiveness without necessarily changing the objective resources of the ingroup or the outgroup. This may be achieved by comparing the ingroup to the outgroup on some new dimension, changing the values assigned to the attributes of the group, and choosing an alternative outgroup by which to compare the ingroup.
