Risk Assessment in Environmental Policymaking

Audrey M. Armour

Review of Policy Research, 1993, vol. 12, issue 3‐4, 178-196

Abstract: A problem in policymaking for prevention of harm to persons and the environment concerns the probability of harm occurring—that is, the measure of risk involved. Policymakers have almost always sought to calculate the risk involved in proposed courses of action. Their methods have often been irrational and their estimates erroneous. Explicit analysis of risk to society and systematic methods for estimating it emerged with the advent of science as more reliable procedures for prediction and decision‐making. However, as with many other forms of analysis, the assessment of risk has carried its own risk—namely an undue reliance on logical quantitative techniques which fail to address the root causes of public concern and apprehension. Common‐sense assessments of risk tell us more what risks people regard as acceptable and risks arouse anxiety and protest. Carnage from accidents on the nation's highways arouse much less apprehension than nuclear accidents even though actual risk from automobiles is much greater than injury or death from nuclear reactors. The following paper makes the case that the art and science of risk assessment will fall short of social and political realities until the psychological and cultural aspects of risk receive more adequate attention.
