Risk and Rationality: Philosophical Foundations for Populist Reforms offers a rigorous philosophical reconstruction of how societies should evaluate and govern technological hazards. K. S. Shrader-Frechette charts a "middle path" between cultural relativism and naive positivism, demonstrating why risk evaluation is neither a mere social construct nor a value-free technical exercise. After situating modern risk analysis in its institutional history (NEPA, OSHA, RARADA), she dissects the value judgments embedded in all three stages of assessment-identification, estimation, and evaluation-showing how methodological choices shape policy outcomes. Through targeted critiques of prevailing strategies-expert/lay splits between "perceived" and "actual" risk, probability-only decision rules, Bayesian-utilitarian maximization under deep uncertainty, producer-favoring default choices, and the "isolationist" discounting of Third-World harms-Shrader-Frechette argues that lay aversion to involuntary, catastrophic, or inequitably distributed risks is often more rational than experts concede.The book's constructive core advances "scientific proceduralism," a normative framework that weds empirical objectivity to democratic ethics. Risk evaluations, Shrader-Frechette contends, can be objective-insofar as they are probabilistically revisable and open to critical testing-while also answerable to principles of equity, consent, and due process. She proposes methodological reforms (ethically weighted risk-cost-benefit analysis; performance-based ranking of expert judgments by predictive accuracy) and procedural reforms (free, informed consent for imposed risks; compensation and due-process rights; market-share liability) that realign assessment and management with public reason. Bridging philosophy of science, environmental ethics, and policy analysis, Risk and Rationality supplies scholars and practitioners with a defensible account of rational risk governance-one that explains persistent public opposition to hazardous sitings without pathologizing citizens, and that equips analysts to design evaluations and institutions capable of earning democratic legitimacy.This title is part of UC Press's Voices Revived program, which commemorates University of California Press's mission to seek out and cultivate the brightest minds and give them voice, reach, and impact.
