Decision Science in Public Policy: Evidence, Values, and Accountable Judgment
Decision Science in Public Policy examines how analytical frameworks, behavioral insight, and systems thinking shape the design, evaluation, and implementation of policies that affect collective outcomes. The article argues that public policy is especially demanding for decision science because choices must be made under uncertainty, political constraint, institutional complexity, and competing objectives such as efficiency, equity, resilience, and legitimacy. It develops this through policy analysis tools, behavioral approaches such as nudging, systems thinking, robust decision-making under uncertainty, explicit treatment of trade-offs, implementation dynamics, and public-policy-specific mathematical and computational workflows. The article emphasizes that stronger policy decisions depend not only on better analysis, but on building transparent, adaptable, and accountable architectures of collective judgment that can respond to feedback, institutional limits, and unequal social impacts over time.
