This paper surveys the current philosophical discussion of the ethics of risk imposition, placing it in the context of relevant work in psychology, economics and social theory. The central philosophical problem starts from the observation that it is not practically possible to assign people individual rights not to be exposed to risk, as virtually all activity imposes some risk on others. This is the ‘problem of paralysis’. However, the obvious alternative theory that exposure to risk is justified when its total (...) benefits exceed its total costs faces the standard distributional challenges of consequentialism. Forms of contractualism have been proposed as a solution, but how exactly such theories can be formulated remains problematic, especially when confronted with the difficult cases of mass, novel, risk such as climate change.

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.
