Quick Answer: An evidence-based practice is any practice that relies on scientific evidence for guidance and decision-making. Practices that are not evidence-based may rely on tradition, intuition, or other unproven methods. Evidence-based practices have been gaining ground since the formal introduction of evidence-based medicine in 1992, and have spread to the allied health professions, education, management, law, public policy, and other fields. In light of studies showing problems in scientific research, there is also a movement to apply evidence-based practices in scientific research itself. Research into the evidence-based practice of science is called metascience. The movement towards evidence-based practices attempts to encourage, and in some instances to force, professionals and other decision-makers to pay more attention to evidence to inform their decision-making.
