Coined in the late 20th century, the term combines evidence (derived from Latin evidentia, meaning distinctness or plainness) and based (from Old English bäst, relating to a foundation). It originated primarily within medical contexts (evidence-based medicine) before expanding across public policy, education, and social sciences to signify practices grounded in empirical research.
