Intersectionality is a critical analytical framework for social psychology. I have organised this chapter into four sections. First, I provide a historical overview of intersectionality. Second, using some of intersectionality’s core tenets as a foundation, I critique some traditional assumptions of mainstream social psychological theory and research. Third, I highlight some current trends in intersectional social psychological research. Finally, I conclude with: (a) a brief discussion about why social psychology has been so slow to embrace intersectionality; (b) a summary of the advantages of a more intersectional social psychology; and (c) recommendations of some key references for further reading.
