Toward a socially just diversity science: Using intersectional mixed methods research to center multiply marginalized Black, Indigenous, and People of Color (BIPOC).

Objective Plaut's breakthrough 2010 publication on diversity science-the study of meaningful human differences-set in motion a generative field of theory and research. Yet, to move diversity science forward, innovative methods that explicitly center the experiences of Black, Indigenous, and People of Color (BIPOC) who encounter multiple forms of marginalization must be adopted. One such approach is intersectional mixed methods research-a methodological approach that uses intersectionality theory to guide the use of both quantitative and qualitative methods within a single study. Conclusions We argue that intersectional mixed methods research includes four tenets: (1) research questions prioritize multiply marginalized BIPOC individuals, (2) the multiple realities of BIPOC individuals are honored and embraced, (3) identity-related variables (e.g., self-reported discrimination) are studied alongside systems-level variables (e.g., structural racism), and (4) scholars engage in critical reflexivity. We also propose that intersectional mixed methods research can advance scholarship on multiply marginalized BIPOC individuals by fulfilling one of five purposes: Triangulation, complementarity, expansion, development, and initiation. We close with a discussion of tensions and recommendations. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
