Evidence-based Policymaking

Evidence-based policymaking is the idea that governments should choose and adjust policies using research, data, and evaluation instead of guesswork or habit. It covers how problems become priorities, how ideas spread between governments, and how pilots and studies show what works. Agencies, legislatures, researchers, and statistical offices all contribute.

People usually ask how government decides what to do, when evidence should outweigh values, and how policies are tested, compared, and scaled up. They also ask who shapes policy in practice and how statistics from agencies inform choices.
