 A particular form of recognitional injustice is epistemic injustice as diagnosed by Miranda Fricker (Fricker 2007). This occurs when someone is wronged in their capacity as a source of knowledge, and it takes two main forms: testimonial injustice and hermeneutic injustice. As Fricker explains ‘testimonial injustice occurs when prejudice causes a hearer to give a deflated level of credibility to a speaker’s word; hermeneutical injustice occurs at a prior stage when a gap in collective interpretive resources puts someone as at an unfair disadvantage when it comes to making sense of their social experiences’ (Fricker 2007, p. 1). She argues that testimonial injustice matters for two reasons. First, the person who suffers from it is less able to protect or advance their interests – for example they are less likely to be believed when having to defend themselves in court. Second, since others are unwilling to regard them as competent sources of knowledge, they may lose trust in their own capacity to know, leading in some cases to ‘prolonged self-doubt and loss of intellectual confidence’.
