Σύνοψη	A randomized controlled trial (RCT) in criminology evaluates a justice intervention — such as hot-spots policing, a deterrence message, or a reentry program — by randomly assigning units (places, people, or cases) to receive the intervention or to serve as controls. Because assignment is by chance, treatment and control groups are statistically equivalent at baseline, so any later difference in crime or reoffending can be attributed to the intervention rather than to selection. Sherman and Weisburd's 1995 Minneapolis hot-spots patrol experiment helped establish the design as the gold standard of experimental criminology.	Deterrence analysis studies how the threat and imposition of legal punishment discourage crime. Rooted in classical criminology and formalized in Gary Becker's economic model, it distinguishes the certainty, severity, and celerity of punishment, separates perceived from objective sanction risk, and uses quasi-experimental and perceptual evidence — synthesized by Daniel Nagin — to test how much, and through what channels, punishment actually deters.
