Argumentative Turn in Policy Analysis

_This§book describes argumentative tools and strategies that can be used to guide§policy decisions under conditions of great uncertainty. Contributing authors§explore methods from philosophical analysis and in particular argumentation§analysis, showing how it can be used to systematize discussions about policy§issues involving great uncertainty.§§The first part of the work explores§how to deal in a systematic way with decision-making when there may be plural§perspectives on the decision problem, along with unknown consequences of what§we do. Readers will see how argumentation tools can be used for prioritizing§among uncertain dangers, for determining how decisions should be framed, for§choosing a suitable time frame for a decision, and for systematically choosing§among different decision options. Case studies are presented in the§second part of the book, showing argumentation in practice in the areas of§climate geoengineering, water governance, synthetic biology, nuclear waste, and§financial markets. In one example, argumentation analysis is applied to§proposals to solve the climate problem with various technological manipulations§of the natural climate system, such as massive dispersion of reflective§aerosols into the stratosphere. Even after a thorough investigation of such a§proposal, doubt remains as to whether all the potential risks have been§identified. In such discussions, conventional risk analysis does not have much§to contribute since it presupposes that the risks have been identified, whereas§the argumentative approach to uncertainty management can be used to systematize§discussions.§
