Philosophy of Scientific Evidence

A branch of epistemology that investigates the nature, justification, and limits of evidence in science. It asks: what is the relationship between evidence and hypothesis? What makes something evidence? Can evidence be theory‑laden, and if so, does that undermine objectivity? It explores concepts like confirmation, induction, Bayesian updating, and the problem of underdetermination. It also examines the ethics of evidence (e.g., what evidence must researchers disclose?). Unlike sociology (descriptive), philosophy of scientific evidence is normative: it evaluates what good evidence should be and how it should be used.

Philosophy of Scientific Evidence Example: “The philosophy of scientific evidence debates whether a single randomized controlled trial counts as ‘evidence’ for a policy, or whether we need a systematic review. The answer affects whether we trust new drugs—or wait decades.”
