Etymology

The term combines "evidence," from Latin evidentia (clearness, proof), derived from evidens ("obvious," from e- "out" + videre "to see"), with "based," the past participle of "base" (from Old French baser, ultimately from Latin basis "foundation"). The compound emerged in the late 20th century, reflecting a shift toward empirical rigor in fields like medicine and policy-making. The logic is straightforward: practices "founded" on visible, verifiable "proof."
