(Not) just policy success: Incorporating justice in policy evaluation

Despite the recognition that policy evaluations are inherently normative as they are shaped by political and social values, justice is rarely addressed systematically in policy evaluation practice or research. By overlooking structural inequities and failing to scrutinize power dynamics, this omission risks hindering accountability, legitimizing injustice, and inhibiting policy learning. To help bridge this gap, we build on the policy success heuristic, which is a multidimensional approach for assessing programmatic, process, and political outcomes of public policy. Drawing on the philosophical literature on justice, we link three prominent categories—distributive, procedural, and recognition justice—with the dimensions of policy success. Based on this linkage, we propose a reflective framework that uniquely integrates justice principles into each dimension of the policy success heuristic. The framework can be applied ex-ante or ex-post to assess whether a policy is, or is likely to be, not only successful but also just, contributing to navigating the is/ought distinction at the heart of policy evaluation.
