الملخص	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.	A randomized controlled trial (RCT) is the gold standard experimental design in clinical and health research, in which participants are randomly allocated to a treatment group or a control group so that the effect of an intervention can be measured with the highest possible degree of internal validity. The modern parallel-group RCT was formalized by Austin Bradford Hill and the Medical Research Council in their landmark streptomycin trial of 1948, and its reporting is governed today by the CONSORT 2010 guidelines (Schulz et al., 2010).
