Rethinking Intergroup Conflict: An Intersectional Methodological Critique

Theories such as Social Identity Theory (SIT) and Realistic Group Conflict Theory (RGCT) have been foundational in the study of intergroup relations. These frameworks help explain group-based prejudice, resource-driven conflict, and identity-based polarization. Yet, despite their theoretical elegance and empirical utility, these models often adopt a single-axis approach to identity—treating race, gender, or class as isolated variables. This simplification poses serious limitations for understanding how prejudice operates in the lives of individuals who occupy multiple marginalized identities, such as Black women, queer immigrants, or low-income transgender individuals. Intersectionality, originally developed in legal scholarship by Kimberle Crenshaw (1989), offers a critical methodological lens for addressing these shortcomings.

Rather than viewing identities as additive or mutually exclusive categories, intersectionality emphasizes how systems of oppression interact to produce unique forms of marginalization. From a research design standpoint, this perspective challenges the assumption that population subgroups can be analytically disaggregated without loss of meaning. It calls for methodological innovation that recognizes the compounded, non-linear ways in which discrimination manifests.

A closer inspection of SIT and RGCT reveals that both theories tend to privilege relatively homogenous identity categories—e.g., “women” or “Black people”—that overlook intra-group heterogeneity. SIT posits that group-based identification drives intergroup bias, but does not specify how group membership becomes salient when multiple identities intersect. RGCT, while grounded in material competition and threat perception, similarly falls short in accounting for how structural inequalities condition perceptions of threat differently across intersecting identities. In practice, this often leads to the exclusion of multiply marginalized individuals from both experimental samples and analytical models. Integrating intersectionality into intergroup theory necessitates a methodological shift.

One path forward is the intentional design of studies that conceptualize social groups not as static categories, but as relational and structurally embedded. For instance, survey experiments or vignette designs could manipulate intersectional cues—such as varying both racial and gendered attributes of a hypothetical target—to examine how respondents’ prejudice shifts in response. Multilevel modeling and interaction terms can help capture these dynamics statistically, but even more fundamentally, intersectionality invites researchers to reexamine the categories themselves: who gets to define “ingroup” and “outgroup,” and on what basis? This perspective also urges researchers to move beyond cognitive bias and incorporate power and social structure into explanations of prejudice. While social psychological theories have traditionally emphasized mental shortcuts and identity threats, an intersectional approach asks: Who benefits from group hierarchies? How do institutions reinforce selective group boundaries? What role does invisibility play in maintaining status quo biases in data collection and interpretation? The implications for public opinion and survey research are significant. Standard demographic questions—typically restricted to mutually exclusive boxes for race, gender, and sexuality—risk obscuring the very populations most vulnerable to discrimination. Moreover, when survey weights or subgroup analyses are conducted without attention to intersectional configurations, the resulting findings may reinforce dominant-group norms rather than illuminate marginal perspectives.

As the field moves toward more inclusive and equitable methodologies, intersectionality offers not just a critical framework, but a practical imperative. It challenges researchers to rethink how intergroup categories are constructed, operationalized, and interpreted. By doing so, it opens space for more nuanced understandings of prejudice and, crucially, for more targeted interventions. Theories that ignore intersecting identities risk mischaracterizing both the mechanisms and the targets of discrimination. By engaging with intersectionality as a methodological stance, public opinion researchers can better account for the complexity of lived experience—and, in turn, generate insights that are more empirically valid and socially meaningful.
