Testimonial Injustice

A form of epistemic injustice, articulated by Miranda Fricker, in which a speaker's credibility is unjustly deflated because of prejudice attached to their identity. In accessibility and aging research, testimonial injustice occurs when researchers treat older adults' or disabled people's accounts of their own experience as unreliable, confused, or symptomatic — for example, re-coding a participant's refusal to use VR as "technology aversion" rather than as a valid design critique. Recognising testimonial injustice is a prerequisite for participatory and design-justice-aligned research practice.
