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 threatening to their self-perceptions or worldviews and are consequently highly motivated to reduce the distress they feel by denying or avoiding the issue – a multi-faceted response known as White fragility. When White individuals enact a White fragility response, they risk jeopardizing the well-being of Black members of their community and weakening their own motivation for systemic change. Given its stark costs, it is critical to understand White fragility. In this article, we argue that White fragility can be usefully viewed through the lens of emotion regulation theory. In particular, we describe the emotion response and emotion regulation that characterize White fragility, summarize the wide-ranging consequences of White fragility, 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.
