Abstract
There has been a great deal of theoretical discussion about the merits and faults of greater public involvement in technology policy decisions but comparatively less case-based empirical consideration. This article assesses the theoretical and practical implications of two decision styles—technical adversarialism and participatory collaboration—in decision making on the U.S. Chemical Weapons Disposal Program. This case is useful in that it allows for a longitudinal assessment of these two distinct decision approaches applied to the same policy issue and provides an opportunity to evaluate the differential outcomes produced by each. In addition, the high degree of technical complexity and risk involved offers insight into the role lay citizens can play in even the most complicated technical decisions. Comparing the practical consequences of both decision-making approaches suggests that increasing collaboration among citizens and experts can produce decisions that are both politically viable and technically safer than more insular, adversarial forms.
