This book tackles the prevailing contradiction within policy analysis, that rigorous thought should be uncontaminated by values, despite policy analysis being inherently values based. In resolving the issue, this book provides a new, solid foundation for policy analysis. Many policy analysts — and citizens interested in public issues — believe that rigorous thought should be uncontaminated by values, which are merely subjective. Policy analysis, however, is about what is worth doing and therefore inherently values based. This accessible book reveals the damage that this contradiction inflicts on policy analysis and society. It also demonstrates the real-world failings of various influential alternatives to the ‘value-free’ ideal. By showing that values are amenable to critical analysis, this book provides a solid foundation for a comprehensive approach that reimagines the scope and role of policy analysis in contemporary society.
