“…The social identity approach, through its contrast with interdependence and realistic conflict theories, might appear to downplay instrumental explanations, although the focus on social change strategies and beliefs arguably involves instrumental aspects (Tajfel, 1978; see also Scheepers, Spears, Doosje, & Manstead, 2002). Consistent with this, SIT suggests that collective action among the disadvantaged is most likely when group members perceive their disadvantage as "unstable," implying chances of social change (e.g., Bettencourt et al, 2001;Doosje, Spears, & Ellemers, 2002;Ellemers, van Knippenberg, & Wilke, 1990). To some degree, perceiving collective disadvantage as unstable implies a belief that the group is able to address their collective disadvantage through collective effort (e.g., Mummendey et al, 1999; see also Tajfel & Turner, 1979).…”
