Abstract
Objectives The population of randomized experiments in policing is used to examine
co-author and mentoring relations in the professional network of scholars and assess
if experimental criminology is on the path to creating the necessary social capital to
promote the use of randomized controlled trials in criminology and criminal justice
research.
Methods We use systematic review methods to identify the population of policing
experiments. Narrative review and descriptive statistics are used to examine the
growth of policing experiments over time. Social network analysis techniques are
used to analyze and describe the co-authoring and mentoring connections of the
scholars responsible for completing policing experiments.
Results We find that the number of policing experiments increased substantially
between 1970 and 2011. The growth in policing randomized experiments has been
largely generated by a very small number of scholars who account for the bulk of
policing experiments and have been very active in mentoring the next generation of
experimentalists. Another important factor associated with the rise in policing exper-
iment is the availability of federal funding.
