How to argue about the new public management

Hood and Jackson's (1991) distinction between administrative argument and administrative philosophy has been largely overlooked in writings on NPM. This seemingly subtle distinction flows from the more obvious one between “practical argument” and “social scientific explanation.” These terms refer to different scholarly practices. Practical reasoning is a highly-developed form of scholarship in law, public policy, and political theory. Explanation is a highly-developed scholarly activity in political science and related disciplines. The fact that practical argument and explanation are, in principle, complementary scholarly activities in practically-oriented fields such as public management is not a reason to overlook the distinction between them. If scholars writing on NPM made more of this distinction, it might prove easier for their readers to see precisely how social science explanations and practical arguments are interrelated. Discussion of how well claims have been supported would then be facilitated. Also, it would be easier for writers to decide how to engage the NPM literature. Not only would the issues be clearer, but it would also be easier to discuss the merits of alternative approaches to tackling them. If more weight is given to the distinction between practical argumentation and social scientific research by scholars of NPM, an urgent question is: how should the scholarly practice of practical argumentation be characterized?
