The conception of epistemic injustice as a campaign tool has generated considerable debate. The challenge lies in identifying instances of testimonial injustice within complex real-world situations. Miranda Fricker suggests that credibility deficits and identity prejudice serve as necessary conditions for recognizing testimonial injustice. However, this approach faces conceptual generalisation: certain cases that intuitively seem to fit the definition fail to meet the criteria, while some cases that meet the criteria appear counterintuitive. Addressing this issue by introducing additional conditions alongside the original ones seems ineffective and redundant. Simply reverting to Fricker’s original definition is not a straightforward solution either. Identity prejudice plays a decisive role in Fricker’s establishment of testimonial injustice, but it is itself a broad and vague concept. The blurry boundary between heuristics and prejudices has led to many difficulties. An examination of the nature of prejudice indicates that the initial prejudice condition should be modified. It is epistemic inertia, rooted in our thought processes, that serves as the catalyst rendering heuristics unreliable and triggering various epistemic vices, including identity prejudice. Therefore, the prejudice condition is too narrow, while the superordinate concept of epistemic vice is more fundamental as a necessary condition for testimonial injustice.
