Deliberative scholars have suggested that citizens should be able to exchange arguments in public forums. A key element in this exchange is the rational mode of communication, which means speaking through objective argumentation. However, some feminists argue that this mode of communication may create or intensify epistemic injustices. Furthermore, we should not assume that everyone is equally equipped to take part in deliberation. Certain groups, such as Indigenous peoples, for instance, who may not be versed in rational forms of argumentation, (...) may not be listened to or involved sufficiently in the deliberative process. Therefore, it seems we need an alternative mode of communication, such as storytelling, which is a first-person or collective narrative. Given this, how should we pursue this goal? This article aims to answer this question by analysing a local conflict involving an Indigenous tribe and a neighbouring community in Brazil and exploring the underlying testimonial and hermeneutical injustices. I argue that storytelling has an important normative and institutional role in public deliberation and show that its applied version could overcome epistemic injustices and lead to better public policies.
