| Summary: | Can the impact of justice processes be enhanced with the inclusion of a heterogeneous component into an existing cost-benefit analysis app that demonstrates how benefactors and beneficiaries are affected Such a component requires (i) moving beyond the traditional cost-benefit conceptual framework of utilizing averages, (ii) identification of social group or population-specific variation, (iii) identification of how justice processes differ across groups/populations, (iv) distribution of costs and benefits according to the identified variations, and (v) utilization of empirically informed statistical techniques to gain new insights from data and maximize the impact for beneficiaries. This paper outlines a method for capturing heterogeneity. The paper tests the method and the cost-benefit analysis online app that was developed using primary data collected from a developmental crime prevention intervention in Australia. The paper identifies how subgroups in the intervention display different behavioral adjustments across the reference period, revealing the heterogeneous distribution of costs and benefits. Finally, the paper discusses the next version of the cost-benefit analysis app, which incorporates an artificial intelligence-driven component that reintegrates individual cost-benefit analysis projects using machine learning and other modern data science techniques. The paper argues that the app enhances cost-benefit analysis, development outcomes, and policy making efficiency for optimal prioritization of criminal justice resources. Further, the app advances the policy accessibility of enhanced, social group-specific data, illuminating optimal policy orientation for more inclusive, just, and resilient societal outcomes-an approach with potential across broader public policy
