This entry examines how testimony transmits knowledge and how identity prejudice, institutional authority, and platforms distribute credibility.
1.Knowledge was never a solo project
Our knowledge of history, medicine, and even our own birthdays depends on testimony. Reductionists require independent evidence for a speaker’s trustworthiness. Anti-reductionists hold that intelligible testimony provides prima facie justification when no defeater is present.
2.Who gets treated as credible
Credibility is not always allocated according to evidence. Identity prejudice may systematically discount some speakers, while institutional roles can invite excessive trust. Epistemic injustice therefore expands epistemology from individual belief to the social conditions of speaking and being heard.
3.Major Positions
Reductionism
Testimonial warrant must be supported by perception, memory, or experience of speakers.
Anti-reductionism
Absent defeaters, understood testimony has default epistemic authority.
Social epistemology
Knowledge assessment must examine how institutions and identities distribute credibility.
