Despite good intentions, some researchers reproduce oppressions towards marginalized groups in their research. This article focusses specifically on the development of allyship practices in social work research in order to avoid reproducing oppressions. Mobilizing epistemic injustices as theoretical framework, this article suggests that allyship practices should be grounded in the concept of epistemic proximity. After a critical review of the literature on the concepts of allyship and proximity, this article offers a redefinition of the concept of epistemic proximity first developed in geography and economics in light of theories of epistemic injustices. Finally, it proposes some recommendations for allyship practices.
