The precautionary principle is an emerging principle of international law but has only recently been proposed in North America as a new basis for environmental policy. On the surface it is a simple, common-sense proposition: in the face of possible harm, exercise precaution. But the enthusiasm the principle has stirred among public advocates suggests it has a deeper appeal. It is, in fact, based on values related to “forecaring for life” and the natural world. The principle cannot effectively be invoked (...) without stating these values up front. The principle makes it clear that decisions and developments in science and technology are based first of all on values and only secondarily on scientific and technological fact and process. Moreover, a precautionary approach is best carried out in the context of goals that embody the values of communities and societies. (shrink)

Ulrich Beck and other theorists of reflexive modernization are allies in the general project to reduce technocracy and elitism by rendering decision making more democratic and robust. However, this study of U.S. climate politics reveals complexities and obstacles to the sort of democratized decision making envisioned by such theorists. Since the early 1990s, the U.S. public has been subjected to numerous media-driven campaigns to shape understandings of this widely perceived threat. Political interests have instigated an important part of these campaigns, (...) frequently resorting to ethically problematic tactics to undermineattemptsat policy action designed to avert or reducethe threat. The disproportionate in fluence of such interests suggests the need for a more level political playing field characterized by more equalized access to power and influence. (shrink)

"This volume emerged from workshops held at Pennsylvania State University in 2003 and Stanford University in 2005"--P. vii.

The U.S. scientific community has long led the world in research on such areas as public health, environmental science, and issues affecting quality of life. These scientists have produced landmark studies on the dangers of DDT, tobacco smoke, acid rain, and global warming. But at the same time, a small yet potent subset of this community leads the world in vehement denial of these dangers. -/- Merchants of Doubt tells the story of how a loose-knit group of high-level scientists and (...) scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades. Remarkably, the same individuals surface repeatedly-some of the same figures who have claimed that the science of global warming is "not settled" denied the truth of studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole. "Doubt is our product," wrote one tobacco executive. These "experts" supplied it. -/- Naomi Oreskes and Erik M. Conway, historians of science, roll back the rug on this dark corner of the American scientific community, showing how ideology and corporate interests, aided by a too-compliant media, have skewed public understanding of some of the most pressing issues of our era.

Since skepticism is a familiar and critical feature of the realm of science, scientists generally presume that criticisms — even vigorous, cutthroat criticisms — are offered in the spirit of advancing scientific understanding and without hidden ...

These are just some of the many controversial and timely questions that Sheila Jasanoff asks in this study of the way science advisers shape federal policy.
