AbstractAlthough White allies attempt to support racial justice movements, their behaviors can be interpreted as performative rather than genuine by racially minoritized individuals. In the current work, I discuss how White individuals' personal connection to their racial identity and the power it confers—White identity form—shapes their allyship behaviors. Specifically, moving beyond conceptualizations of White identity as centrality, I call for a study of White identity that incorporates power‐relevant ideologies, understanding how White individuals make meaning of their unearned privilege and incorporate it into their self‐concept. I suggest that a power‐cognizant identity form, which involves personally connecting the self to Whiteness and unearned power, is necessary for White individuals to engage in genuine anti‐racist allyship. I discuss White identity measurement issues as well as potential interventions for promoting a power‐cognizant identity form.
