The policy sciences as science

The preceding evaluation of the policy sciences by Schneider, Stevens, and Tornatzky is based on a rather narrow conception of science that emphasizes quantitative and rigorous methods. It overlooks the limitations of such methods, as revealed by the results of applications, and certain adjustments to these limitations. The latter include the adoption of more modest but realizable aspirations and the synthesis of diverse methods-qualitative as well as quantitative, exploratory as well as confirmatory. It also overlooks differences and trends in epistemological preconceptions that underlie the conduct of research and the interpretation of research results. This article reviews the relevant literature in the hope that it might eventually contribute to more enlightened evaluations of the emerging discipline.
