This is an exploratory study of the efficacy of Inside Criminal Justice (ICJ), an eight-week long course for incarcerated students and public prosecutors that fosters respectful and open discussions about the criminal-legal system in order to rethink public safety. ICJ’s impact falls within applied contact theory, intergroup relations, and interventions aimed at reducing bias. The ICJ course was founded in 2018 as a joint initiative between three key institutions in the Tri-State Area (New York, New Jersey, Connecticut): the District Attorney’s Office, the Department of Corrections and Community Supervision (DOCCS), and Columbia University. ICJ brings current prosecutors inside correctional facilities to learn about and discuss issues of criminal justice alongside incarcerated students while developing joint policy proposals centered on improving the justice system. This program is the first of its kind in the area. Through semi-structured interviews of students and prosecutors from across the seven cohorts and qualitative data analysis, this dissertation considers the impact of ICJ on three domains: pre-existing beliefs related to the justice system, changes to concrete behaviors, and network building/transformation. It presents evidence of a reciprocal humanizing experience for its participants that helps shift perceptions, as suggested by Allport's (1954) contact hypothesis. It then examines the translation of that shift to individual and larger-scale changes resulting from ICJ involvement, and explores the distinct forms of credibility ICJ networks give to its participants as well as the ways network failure contribute to justice involvement. There is limited literature about programs that bring these types of criminal justice actors together in an educational setting. In addition to informing a larger, more systematic program evaluation, this exploratory study identifies key themes for future exploration, and presents evidence about the program’s efficacy.
