This is a unique, groundbreaking collection of autobiographical essays by leading women in philosophy. It provides a glimpse at the experiences of the generation that witnessed, and helped create, the remarkable advances now evident for women in the field.

Experts often tout highly subjective methods of policy analysis as scientific and value‐free. In The Myth of Scientific Public Policy, Robert Formaini exposes the uncertainties in two of these methods, cost‐benefit analysis and risk assessment. Because of these deficiencies, he concludes that ethics and political philosophy, not science, are the proper foundation for public policy. While Formaini is right to emphasize the value‐ladenness of cost‐benefit analysis and risk assessment, his rejection of scientific methods of policy analysis is questionable. His criticisms, (...) especially in his study of the swine‐ßu case, seem to establish that experts have misused such methods, not that the methods themselves are seriously ßawed. Also, his rejection of cost‐benefit analysis and risk assessment would be more realistic if he offered a well‐developed alternative to these two methods. One such alternative, for example, is ethically weighted cost‐benefit analysis. (shrink)

Verification and validation of numerical models of natural systems is impossible. This is because natural systems are never closed and because model results are always nonunique. Models can be confirmed by the demonstration of agreement between observation and prediction, but confirmation is inherently partial. Complete confirmation is logically precluded by the fallacy of affirming the consequent and by incomplete access to natural phenomena. Models can only be evaluated in relative terms, and their predictive value is always open to question. The (...) primary value of models is heuristic. (shrink)

Comparing alternative scientific theories obviously is relevant to theory assessment, but are comparativists (like Laudan) correct when they also make it necessary? This paper argues that they are not. Defining rationality solely in terms of theories' comparative problem-solving strengths, comparativist philosophers of science like Laudan subscribe to what I call the irrelevance claim (IC) and the necessity claim (NC). According to IC, a scientific theory's being well or poorly confirmed is "irrelevant" to its acceptance; NC is the claim that "all (...) evaluations of research traditions and theories must be made within a comparative context," how any theory "compares with its competitors" (Laudan 1977, 21, 120). Using current competing theories (T1 and T2) of population viability assessment (PVA) for the Florida panther, the paper investigates IC/NC. In part because dominant T2 panther biologists accept IC/NC (which T1 theorists reject), the paper argues that they appear both to have accepted flawed T2 and to have contributed to flawed panther science and policy. Correcting Laudan's Comparativist Philosophy of Science (LCPS), underlying the T1-versus-T2 debate, thus may hold promise for helping resolve both the scientific and policy controversy over panther PVA.

Workers generally face higher levels of pollution and risk in their workplace than members of the public. Economists justify the double standard on the grounds of the compensating wage differential . The CWD, or hazard-pay premium, is the increment in wages, all things being equal, that workers in hazardous environments receive, as compared to other workers. Economists defend the CWD by asserting that workers willingly trade safety for extra money. This essay examines the theory behind the CWD, presents and evaluates (...) economists' Market-Efficiency Argument for the CWD, offers several reasons for questioning the CWD, and applies the Market-Efficiency Argument to a real-world case, that of U. S. nuclear workers. The essay concludes that this argument fails to justify the CWD, at least in the case of U. S. nuclear workers. (shrink)

Who is right? In Risk and Rationality, Kristin Shrader-Frechette argues that neither charges of irresponsible endangerment nor countercharges of scientific illiteracy frame the issues properly.

A leading international expert on environmental issues, Shrader-Frechette brings a new standard of rigor to philosophical discussions of environmental justice in her latest work. Observing that environmental activists often value environmental concerns over basic human rights, she points out the importance of recognising that minority groups and the poor in general are frequently the biggest victims of environmental degradation, a phenomenon with serious social and political implications that the environmental movement has failed to adequately address. She argues for their (...) equal rights to 'environmental justice' and maintains that they should not have to bear most of the weight of the burdens of pollution and resource depletion. Advocating a greater awareness on the part of professionals in a position to help these victims, Shrader-Frechette proposes a more equitable distribution of environmental resources and, in doing so, makes an important contribution to the fields of environmental ethics and applied philosophy.

In this book Shrader-Frechette reveals how politicians, campaign contributors, and lobbyists--and their power over media, advertising, and public relations--have conspired to cover up environmental disease and death.

This is the first book on practical philosophy of science and how to practically evaluate scientific findings that have life-and-death consequences. Showing how to uncover scores of scientific flaws -- typically used by special interests who try to justify their deadly pollution -- this book aims to liberate the many potential victims of environmentally-induced disease and death.

The accidents at Three Mile Island and Chemobyl have slowed the development of commercial nuclear fission in most industrialized countries, although nuclear proponents are trying to develop smaller, allegedly “fail-safe” reactors. Regardless of whether or not they succeed, we will face the problem of radioactive wastes for the next million years. After a brief, “revisionist” history of the radwaste problem, Isurvey some of the major epistemological and ethical difficulties with storing nuclear wastes and outline four ethical dilemmas common to many (...) technological and environmental controversies. I suggest two solutions to these ethical dilemmas and show why they are also economical and realistic proposals. (shrink)

What Will Work makes a rigorous and compelling case that energy efficiencies and renewable energy-and not nuclear fission or "clean coal"-are the most effective, cheapest, and equitable solutions to the pressing problem of climate change.

While their strength, electrical, optical, or magnetic properties are expected to contribute a trillion dollars in global commerce before 2015, nanomaterials also appear to pose threats to human health and safety. Nanotoxicology is the study of these threats. Do nanomaterial benefits exceed their risks? Should all nanomaterials be regulated? Currently nanotoxicologists cannot help answer these questions because too little is known about nanomaterials, because their properties differ from those of bulk materials having the same chemical composition, and because they differ (...) so widely in their applications. Instead, this paper answers a preliminary ethical question: What nanotech policies are likely to contribute to society’s ability to give or withhold free informed consent to the potential risks associated with production and use of nanomaterials? This paper argues that at least four current policies appear to jeopardize the risk-disclosure condition that is required for informed consent. These are the funding problem, the conflict-of-interest problem, the labeling problem, and the extrapolation problem. Apart from future decisions on how to ethically make, use, and regulate nanomaterials, this paper argues that, at a minimum, these four policies must be modified. Government must spend greater monies on nanotoxicology; ensure independent nanotoxicology research; label consumer products containing nanomaterials; and avoid assuming that nanotoxicological properties are based merely on mass and chemical composition. Otherwise free informed consent to these new technologies and materials may be jeopardized. (shrink)

Neoclassical economists have been telling us for years that if we behave in egoistic, individualistic ways, the invisible hand of the market will guide us to efficient and sustainable futures. Many contemporary Greens also have been assuring us that if we behave in holistic ways, the invisible hand of ecology will guide us to health and sustainable futures. This essay argues that neither individualism nor holism will provide environmental sustainability. There is no invisible hand, either in economics or in ecology. (...) Humans have no guaranteed tenure in the biosphere. Likewise there is no philosophical quick fix for environmental problems, either through the ethical individualism of Feinberg, Frankena, and Regan, or through the ecological holism of Callicott and Leopold. The correct path is more complex and tortuous than either of these ways. The essay argues that the best way to reach a sustainable environmental future probably is through a middle path best described as "hierarchical holism.". (shrink)

We examine the evolution of the concept of stability in community ecology, arguing that biologists have moved from an emphasis on biotic communities characterized by static balance, to one of dynamic balance (returning to equilibrium after perturbation), to the current concept of stability as persistence. Using Wimsatt's (1987) analysis of how false models can often lead to better ones, we argue that failed attempts to link complexity with stability have significant heuristic value for community ecologists. Nevertheless, we argue that, (A) (...) because there is no common characteristic that stability terms presuppose, community ecology might be better served by abandoning the concept of stability and by employing instead specific terms such as 'persistence', 'resistance', and 'variability'. (B) The current emphasis (of stability terms) on persistence of species provides little basis for explaining possible mechanisms that might account for persistence. (shrink)

One way to do socially relevant investigations of science is through conceptual analysis of scientific terms used in special-interest science (SIS). SIS is science having welfare-related consequences and funded by special interests, e.g., tobacco companies, in order to establish predetermined conclusions. For instance, because the chemical industry seeks deregulation of toxic emissions and avoiding costly cleanups, it funds SIS that supports the concept of "hormesis" (according to which low doses of toxins/carcinogens have beneficial effects). Analyzing the hormesis concept of its (...) main defender, chemical-industry-funded Edward Calabrese, the paper shows Calabrese and others fail to distinguish three different hormesis concepts, H, HG, and HD. H requires toxin-induced, short-term beneficial effects for only one biological endpoint, while HG requires toxin-induced, net-beneficial effects for all endpoints/responses/subjects/ages/conditions. HD requires using the risk-assessment/regulatory default rule that all low-dose toxic exposures are net-beneficial, thus allowable. Clarifying these concepts, the paper argues for five main claims. (1) Claims positing H are trivially true but irrelevant to regulations. (2) Claims positing HG are relevant to regulation but scientifically false. (3) Claims positing HD are relevant to regulation but ethically/scientifically questionable. (4) Although no hormesis concept (H, HG, or HD) has both scientific validity and regulatory relevance, Calabrese and others obscure this fact through repeated equivocation, begging the question, and data-tri mm ing. Consequently (5) their errors provide some undeserved rhetorical plausibility for deregulating low-dose toxins. (shrink)

Because of the problems associated with ecological concepts, generalizations, and proposed general theories, applied ecology may require a new "logic" of explanation characterized neither by the traditional accounts of confirmation nor by the logic of discovery. Building on the works of Grunbaum, Kuhn, and Wittgenstein, we use detailed descriptions from research on conserving the Northern Spotted Owl, a case typical of problem solving in applied ecology, to (1) characterize the method of case studies; (2) survey its strengths; (3) summarize and (...) respond to its shortcomings; and (4) investigate and defend its underlying "logic".

Many people argue that uncertain science—or controversial policies based on science—can be clarified primarily by greater attention to social/political values influencing the science and by greater attention to the vested interests involved. This paper argues that while such clarification is necessary, it is not a sufficient condition for achieving better science and policy; indeed its importance may be overemphasized. Using a case study involving the current, highly politicized controversy over the shape of dose‐response curves for biological effects of ionizing radiation, (...) the paper argues that the conflict could be significantly resolved through specific methodological improvements in the areas of metascience and philosophy of science. These improvements focus on taking account, respectively, of scale, data trimming, aggregation, measurability, and simplicity. (shrink)

Eighty percent of (commercial) genetically engineered seeds (GES) are designed only to resist herbicides. Letting farmers use more chemicals, they cut labor costs. But developing nations say GES cause food shortages, unemployment, resistant weeds, and extinction of native cultivars when “volunteers” drift nearby. While GES patents are reasonable, this paper argues many patent policies are not. The paper surveys GE technology, outlines John Locke’s classic account of property rights, and argues that current patent policies must be revised to take account (...) of Lockean ethical constraints. After answering a key objection, it provides concrete suggestions for implementing its ethical conclusions. (shrink)

Within the last 20 years, the US has mounted amassive campaign against invasions bynon-indigenous species (NIS) such as zebramussels, kudzu, water hyacinths, and brown treesnakes. NIS have disrupted native ecosystemsand caused hundreds of billions of dollars ofannual damage. Many in the scientificcommunity say the problem of NIS is primarilypolitical and economic: getting governments toregulate powerful vested interests thatintroduce species through such vehicles asships' ballast water. This paper argues that,although politics and economics play a role,the problem is primarily one of scientificmethod. (...) Even if commercial interests werewilling to spend the necessary funds to controlNIS, and even if government were willing toregulate them, ecological theory is notadequate to provide clear direction for eithereffort. The paper argues there is nocomprehensive, predictive theory ofinvasibility, as part of a larger theory ofcommunity structure, that might guideecological decision making regarding NIS, andfor at least three reasons. (1) There is nofirm definition of NIS, native, exotic,and so on, and ecologists do not use the termsconsistently; as a result, biologists debatingvarious accounts of community structure andecological explanation often do not even makelogical contact with each other. (2) Thedominant theory used to understandinvasibility, island biogeography, has noprecise predictive power and is unable toclarify when NIS might promote biodiversity andwhen they might hinder it. (3) There are nofirm, empirical generalizations that revealwhen a colonizer or a NIS might be likely totake over a new environment, and when it mightnot succeed in doing so. As a result,scientists have only rough rules of thumb toshore up their arguments against NIS. Given theincompleteness of current ecological theory,the paper closes with several suggestions forways that study of NIS might enhanceunderstanding of basic commmunity structuresand vice versa.

Assessing the hydrogeological modeling at the Yucca Mountain and Maxey Flats nuclear repositories reveals a number of important ways in which theory choice can go wrong. The two cases suggest that there are at least six important criteria for evaluating the suitability of scientific models to be used for predictions intended to serve public policy. More generally, the paper argues that applied philosophy of science, as practiced in environmental policymaking, requires one to employ ethical rationality as well as scientific rationality, (...) to heed the advice of the moral philosopher, not merely that of the epistemologist or philosopher of science.

Many scientists, businessmen, and government regulators believe that the criteria for acceptable societal risk are too stringent. Those who subscribe to this belief often accept the view which I call the probability-threshold position. Proponents of this stance maintain that society ought to ignore very small risks, i.e., those causing an average annual probability of fatality of less than 10–6.After examining the three major views in the risk-evaluation debate, viz., the probability-threshold position, the zero-risk position, and the weighted-risk position, I focus (...) on the arguments for the first of these views, since it is the position which currently undergirds most public policy (especially in the U.S.) regarding acceptable risk. After analyzing Arrow's argument from decision theory, Comar's and Gibson's argument from ontology, and Starr's and Whipple's argument from epistemology, I conclude that these defenses of the probability-threshold position err in a variety of ways. Most commonly, they fail because they tacitly accept the assumption that magnitude of probability, alone, provides a sufficient condition for judging the acceptability of a given risk. In the light of these errors, I suggest that it might be more desirable for risk assessors, decision theorists, and policymakers to weight various risk-cost-benefit parameters according to alternative ethical criteria, rather than to evaluate risks solely in terms of mathematical considerations.

Conservation planning is only as good as the science on which it relies. This paper evaluates the science underlying the least-cost-path model, developed by Meegan and Maehr (2002) , for the Florida panther, Puma concolor coryi. It also assesses the resulting claim that private lands in central Florida are desirable for panther colonization (Maehr et al. 2002a , p. 187; Maehr 2001 , pp. 3–4; Maehr and Deason 2002 , p. 400). The paper argues that panther conservation planning, as proposed (...) by Maehr, is flawed because of its (1) poor analysis of panther-habitat requirements, owing largely to use of only daytime telemetry, a black-box model, and failure to take account of spatial and temporal uncertainties; (2) use of stipulative and misleading definitions of key biological terms, such as “forest obligate” and panther “dispersal”; (3) employment of question-begging value judgments to rank habitat; (4) weak testing of the model; (5) inconsistency in evaluation of forest habitat; (6) inconsistency in evaluation of agricultural lands; and (7) inconsistency in assessing effects of highways on panther habitat.

On August 22, 2005 the U.S. Environmental Protection Agency issued proposed new regulations for radiation releases from the planned permanent U.S. nuclear-waste repository in Yucca Mountain, Nevada. The goal of the new standards is to provide public-health protection for the next million years — even though everyone admits that the radioactive wastes will leak. Regulations now guarantee individual and equal protection against all radiation exposures above the legal limit. Instead E.P.A. recommended different radiation exposure-limits for different time periods. It also (...) recommended using only the arithmetic mean of the dose distribution, to assess regulatory compliance during one time period, but using only the median dose to assess compliance during another period. This piece argues that these two changes — in exposure-limits and in methods of assessing regulatory compliance — have at least four disturbing consequences. The changes would threaten equal protection, ignore the needs of the most vulnerable, allow many fatal exposures, and sanction scientifically flawed dose calculations. (shrink)

This article shows why it is important to do normative or practical philosophy of science, especially philosophy of science that criticizes and evaluates contemporary use of scientific methods to analyze welfare-affecting societal problems. The article introduces the scientific, ethical, and social problem of environmental injustice—disproportionate environmental and pollution threats that are responsible for roughly 40% of all preventable disease and death. Next it explains that many deadly threats continue in part because of “special-interest science”, methodologically flawed science that is done (...) to promote corporate profits, rather than truth, then argues that philosophers of science should use normative or practical philosophy of science to critique and expose special-interest science. To illustrate special-interest science, the article provides two case studies, on diesel-particulate-matter pollution and on organophophate-pesticide pollution, and shows how diesel and pesticide polluters use special-interest science. For instance, they often ignore observational data, illegitimately demand statistically significant evidence of harm from observational data, use small sample sizes, do the wrong tests, or demand certainty—rather than a preponderance of evidence—to justify a conclusion about pollution harm. They also use flawed normative arguments to defend both diesel and pesticide pollution. The article concludes that, given the epistemic, scientific, human-welfare toll of special-interest science, philosophers of science need to do normative or practical philosophy of science that exposes these scientific flaws.

Merck suppressed data on harmful effects of its drug Vioxx, and Guidant suppressed data on electrical flaws in one of its heart-defibrillator models. Both cases reveal how financial conflicts of interest can skew biomedical research. Such conflicts also occur in electric-utility-related research. Attempting to show that increased atomic energy can help address climate change, some industry advocates claim nuclear power is an inexpensive way to generate low-carbon electricity. Surveying 30 recent nuclear analyses, this paper shows that industry-funded studies appear to (...) fall into conflicts of interest and to illegitimately trim cost data in several main ways. They exclude costs of full-liability insurance, underestimate interest rates and construction times by using overnight costs, and overestimate load factors and reactor lifetimes. If these trimmed costs are included, nuclear-generated electricity can be shown roughly 6 times more expensive than most studies claim. After answering four objections, the paper concludes that, although there may be reasons to use reactors to address climate change, economics does not appear to be one of them. (shrink)

US testing of nuclear weapons has resulted in about 800,000 premature fatal cancers throughout the globe, and the nuclear tests of China, France, India, Russia, and the UK have added to this total. Surprisingly, however, these avoidable deaths have not received much attention, as compared, for example, to the smaller number of US fatalities on 9-11-01. This essay (1) surveys the methods and models used to assess effects of low-dose ionizing radiation from above-ground nuclear weapons tests and (2) explains some (...) of the epistemological and logical problems (with these methods and models) that have caused scientists to decide against health screening of the most likely test victims. It also (3) argues that, once the faulty presuppositions and question-begging frames about testing and screening are recognized, there are compelling arguments in favor of nuclear-test nations'' screening fallout victims, at least among their citizens. Finally, it (4) suggests that logically and epistemically flawed fallout studies/recommendations against screening are more like to occur when scientists adopt a Laudan-style comparativist rationality, rather than when they adopt a metascience more like that of Kuhn and others.

Scientists are divided on the status of hypothesis H that low doses of ionizing radiation (under 20 rads) cause hormetic (or non-harmful) effects. Military and industrial scientist s tend to accept H, while medical and environmental scientists tend to reject it. Proponents of the strong programme claim this debate shows that uncertain science can be clari ed only by greater attention to the social values in uencing it. While they are in part correct, this paper argues that methodological analyses (not (...) merely attention to social values) also can help clarify uncertain science. The paper analyzes ve measurement uncertainties , as well as seven methodological value judgments, relevant to H. Using criteria of internal and external consistency, as well as predictive power, it argues that metascience also helps resolve this debate. And if so, then value-laden, policy-relevan t science may need, not only more attention to social values in order to resolve and to clarify disputes, but also more conceptual and methodological analyses of science. (This paper suggests what such methodological analyses might be like and uses the case of low-dose risks from radiation to illustrate its points, while a companion paper (“Chemical Hormesis, Conceptual Clari cation, and the Warrant for Policy-Driven Science”) in this same issue of POS suggests what such conceptual analyses might be like and uses the case of low-dose risks from chemicals to illustrate its points.) If this paper’s thesis holds in the very politicize d “hard case” of radiation hormesis, then it suggests that the metascientist s may be right about what is also often necessary to clarify scienti c disputes.
