To address anti-Black racism, systemic change across many domains in American life will be necessary. There are many barriers to change, however, and progress requires identifying these barriers and developing tools to overcome them. Given that White individuals disproportionately occupy 'gatekeeping' positions of power, one key barrier to systemic change is rooted in White individuals' emotional (and emotion-regulatory) responses when considering their own role in racism (e.g., involvement in racist systems, biased actions). White people often experience such moments as a jeopardy to their valued goals and are consequently highly motivated to reduce the negative emotions they feel by denying or avoiding the issue -a multi-faceted response known as a White fragility response. When White individuals enact a White fragility response, they can further damage the well-being of Black members of their community and weaken their own motivation for systemic change. Given its stark costs, it is critical to understand White fragility responses. In this article, we argue that White fragility can be usefully viewed through the lens of emotion and emotion regulation theory. In particular, we describe the emotion and emotion regulation responses that characterize White fragility, summarize the wide-ranging consequences of White fragility responses, highlight more sustainable ways forward, and end by considering a broader fragility framework that acknowledges multiple dimensions of power. Although emotion regulation lies at the heart of White fragility, emotion regulation is also a tool that can be leveraged for greater justice.
