Some pitfalls of an overemphasis on science in environmental risk management decisions

This paper addresses the question whether calls for "more'' and "better'' science will have the intended effect of improving the quality of decisions about environmental risks. There are reasons to be skeptical: key judgment tasks that fundamentally shape many aspects of decisions about environmental risk management lie outside the domain of science. These tasks include making value judgments explicit, integrating facts and values to create innovative alternatives, and constructively addressing conflicts about uncertainty. To bring new specificity to an old debate, we highlight six pitfalls in environmental risk decisions that can occur as the result of an overemphasis on science as the basis for management choices.
