Define evidence-based policing and describe how it is implemented in agency operations.

• A. Based on tradition and intuition; policies are adopted without evaluation.
• B. Using rigorous research and data to guide strategies, with evaluation and adaptation based on outcomes.
• C. Relying on anecdotes from officers; reforms are implemented without testing.
• D. Focusing solely on patrol numbers and response times.

Answer: (B)

Evidence-based policing means using rigorous research and high-quality data to guide policing decisions, with ongoing evaluation and adaptation based on what the data show. In practice, agencies implement it by identifying problems through data analysis, testing interventions in a controlled or well-monitored way, and measuring outcomes with clear metrics such as crime trends, clearance rates, community impact, and cost-effectiveness. If a strategy works, it’s scaled up; if it doesn’t, it’s adjusted or discarded. This approach also involves collaborating with researchers, employing robust study designs when possible, and creating feedback loops so policies continually improve based on evidence.

The other descriptions miss this combination of research, measurement, and adjustment. One describes relying on tradition and intuition without evaluation, another relies on anecdotes and untested reforms, and the last focuses only on patrol numbers and response times without the broader evidence-and-evaluation frame.
