The role of values in scientific research has become an important topic of discussion in both scholarly and popular debates. Pundits across the political spectrum worry that research on topics like climate change, evolutionary theory, vaccine safety, and genetically modified foods has become overly politicized. At the same time, it is clear that values play an important role in science by limiting unethical forms of research and by deciding what areas of research have the greatest relevance for society. Deciding how (...) to distinguish legitimate and illegitimate influences of values in scientific research is a matter of vital importance.Recently, philosophers of science have written a great deal on this topic, but most of their work has been directed toward a scholarly audience. This book makes the contemporary philosophical literature on science and values accessible to a wide readership. It examines case studies from a variety of research areas, including climate science, anthropology, chemical risk assessment, ecology, neurobiology, biomedical research, and agriculture. These cases show that values have necessary roles to play in identifying research topics, choosing research questions, determining the aims of inquiry, responding to uncertainty, and deciding how to communicate information. Kevin Elliott focuses not just on describing roles for values but also on determining when their influences are actually appropriate. He emphasizes several conditions for incorporating values in a legitimate fashion, and highlights multiple strategies for fostering engagement between stakeholders so that value influences can be subjected to careful and critical scrutiny.

Recent psychology research has established that people do not employ a simple unidimensional scale for attributions of personhood, increasing from non-sentient rocks to mentally complex humans. Rather, there are two personhood dimensions: agency (e.g. planning, deciding, acting) and experience (e.g. feeling, desiring, experiencing). Here we show that this subtle distinction also occurs in the semantic space of natural language. We develop computational-linguistics tools for measuring variation in agency and experience in language and validate the measures against human judgments. To demonstrate (...) the usefulness of the method, we map both dimensions of personhood in historical English-language corpora over the last 200 years. First, we show that while women are now perceived as having similar levels of agency as men, they are still perceived as more patient-like. Second, we show that domesticated animals have gradually gained higher attributions of experience, but not agency, over time. -/- . (shrink)

_Current Controversies in Values and Science_ asks ten philosophers to debate five questions that are driving contemporary work in this important area of philosophy of science. The book is perfect for the advanced student, building up her knowledge of the foundations of the field while also engaging its most cutting-edge questions. Introductions and annotated bibliographies for each debate, preliminary descriptions of each chapter, study questions, and a supplemental guide to further controversies involving values in science help provide clearer and richer (...) snapshots of active controversies for all readers._ _.

Recent efforts to argue that nonepistemic values have a legitimate role to play in assessing scientific models, theories, and hypotheses typically either reject the distinction between epistemic and nonepistemic values or incorporate nonepistemic values only as a secondary consideration for resolving epistemic uncertainty. Given that scientific representations can legitimately be evaluated not only based on their fit with the world but also with respect to their fit with the needs of their users, we show in two case studies that nonepistemic (...) values can play a legitimate role as factors that override epistemic considerations in assessing scientific representations for practical purposes.

This book brings together eleven case studies of inductive risk-the chance that scientific inference is incorrect-that range over a wide variety of scientific contexts and fields. The chapters are designed to illustrate the pervasiveness of inductive risk, assist scientists and policymakers in responding to it, and productively move theoretical discussions of the topic forward.

Both scientists and philosophers of science have recently emphasized the importance of promoting transparency in science. For scientists, transparency is a way to promote reproducibility, progress, and trust in research. For philosophers of science, transparency can help address the value-ladenness of scientific research in a responsible way. Nevertheless, the concept of transparency is a complex one. Scientists can be transparent about many different things, for many different reasons, on behalf of many different stakeholders. This paper proposes a taxonomy that clarifies (...) the major dimensions along which approaches to transparency can vary. By doing so, it provides several insights that philosophers and other science studies scholars can pursue. In particular, it helps address common objections to pursuing transparency in science, it clarifies major forms of transparency, and it suggests avenues for further research on this topic. (shrink)

Could low-level exposure to polluting chemicals be analogous to exercise -- a beneficial source of stress that strengthens the body? Some scientists studying the phenomenon of hormesis claim that that this may be the case.s A Little Pollution Good For You? critically examines the current evidence for hormesis.

This Element introduces the philosophical literature on values in science by examining four questions: How do values influence science? Should we actively incorporate values in science? How can we manage values in science responsibly? What are some next steps for those who want to help promote responsible roles for values in science? It explores arguments for and against the “value-free ideal” for science and concludes that it should be rejected. Nonetheless, this does not mean that value influences are always acceptable. (...) The Element explores a range of strategies for distinguishing between appropriate and inappropriate value influences. It concludes by proposing an approach for managing values in science that relies on justifying, prioritising, and implementing norms for scientific research practices and institutions. (shrink)

Philosophers of science readily acknowledge that nonepistemic values influence the discovery and pursuit of scientific theories, but many tend to regard these influences as epistemically uninteresting. The present paper challenges this position by identifying three avenues through which nonepistemic values associated with discovery and pursuit in contemporary pollution research influence theory appraisal: (1) by guiding the choice of questions and research projects, (2) by altering experimental design, and (3) by affecting the creation and further investigation of theories or hypotheses. This (...) analysis indicates that the effects of these values are sufficiently complex and epistemically significant to merit further attention. †To contact the authors, please write to: Kevin Elliott, Department of Philosophy, University of South Carolina, Columbia, SC 29208; e‐mail: [email protected] .

In recent papers and a book, Heather Douglas has expanded on the well-known argument from inductive risk, thereby launching an influential contemporary critique of the value-free ideal for science. This paper distills Douglas’s critique into four major claims. The first three claims provide a significant challenge to the value-free ideal for science. However, the fourth claim, which delineates her positive proposal to regulate values in science by distinguishing direct and indirect roles for values, is ambiguous between two interpretations, and both (...) have weaknesses. Fortunately, two elements of Douglas’s work that have previously received much less emphasis provide resources for developing a more promising approach for regulating values in science. (shrink)

Although many philosophers have employed the distinction between “direct” and “indirect” roles for values in science, I argue that it merits further clarification. The distinction can be formulated in several ways: as a logical point, as a distinction between epistemic attitudes, or as a clarification of different consequences associated with accepting scientific claims. Moreover, it can serve either as part of a normative ideal or as a tool for policing how values influence science. While various formulations of the distinction may (...) contribute to a normative ideal, they have limited effectiveness for regulating how values influence science. (shrink)

Private companies provide by far the most funding for scientific research and development. Nevertheless, relatively little attention has been paid to the dynamics of industry‐funded research by philosophers of science. This paper addresses this gap by providing an overview of the major strengths and weaknesses of industry research funding, together with the existing recommendations for addressing the weaknesses. It is designed to provide a starting point for future philosophical work that explores the features of industry‐funded research, avenues for addressing concerns, (...) and strategies for making research funded by the private sector as fruitful as possible.

Philosophers of science are increasingly interested in engaging with scientific communities, policy makers, and members of the public; however, the nature of this engagement has not been systematically examined. Instead of delineating a specific kind of engaged philosophy of science, as previous accounts have done, this article draws on literature from outside the discipline to develop a framework for analyzing different forms of broadly engaged philosophy of science according to two key dimensions: social interaction and epistemic integration. Clarifying the many (...) forms of engagement available to philosophers of science can advance future scholarship on engagement and promote more strategic engagement efforts. (shrink)

We argue that the analysis of cognitive attitudes should play a central role in developing more sophisticated accounts of the proper roles for values in science. First, we show that the major recent efforts to delineate appropriate roles for values in science would be strengthened by making clearer distinctions among cognitive attitudes. Next, we turn to a specific example and argue that a more careful account of the distinction between the attitudes of belief and acceptance can contribute to a better (...) understanding of the proper roles for values in a case study from paleoanthropology.

There has been relatively little effort to provide a systematic overview of different forms of exploratory experimentation (EE). The present paper examines the growing subdiscipline of nanotoxicology and suggests that it illustrates at least four ways that researchers can engage in EE: searching for regularities; developing new techniques, simulation models, and instrumentation; collecting and analyzing large swaths of data using new experimental strategies (e.g., computer-based simulation and "high-throughput" instrumentation); and structuring an entire disciplinary field around exploratory research agendas. In order (...) to distinguish these and other activities more effectively, the paper proposes a taxonomy that includes three dimensions along which types of EE vary: (1) the aim of the experimental activity, (2) the role of theory in the activity, and (3) the methods or strategies employed for varying experimental parameters.

The literature on values in science struggles with questions about how to describe and manage the role of values in scientific research. We argue that progress can be made by shifting this literature’s current emphasis. Rather than arguing about how non-epistemic values can or should figure into scientific assessment, we suggest analyzing how scientific assessment can accommodate non-epistemic values. For scientific assessment to do so, it arguably needs to incorporate goals that have been traditionally characterized as non-epistemic. Building on this (...) insight, we show how the adequacy-for-purpose framework recently developed for assessing scientific models can provide a general framework for describing scientific assessment so that it goes beyond purely epistemic considerations. Adopting this framework has significant advantages and opens the possibility of effecting a partial rapprochement between critics and proponents of the value-free ideal. (shrink)

This response addresses the excellent responses to my book provided by Heather Douglas, Janet Kourany, and Matt Brown. First, I provide some comments and clarifications concerning a few of the highlights from their essays. Second, in response to the worries of my critics, I provide more detail than I was able to provide in my book regarding my three conditions for incorporating values in science. Third, I identify some of the most promising avenues for further research that flow out of (...) this interchange. (shrink)

A number of scholars have recently drawn attention to the importance of iteration in scientific research. This paper builds on these previous discussions by drawing a distinction between epistemic and methodological forms of iteration and by clarifying the relationships between them. As defined here, epistemic iteration involves progressive alterations to scientific knowledge claims, whereas methodological iteration refers to an interplay between different modes of research practice. While distinct, these two forms of iteration are related in important ways. Contemporary research on (...) the biological effects of nanomaterials illustrates that methodological iteration can help to “initiate,” “equip,” and “stimulate” epistemic iteration. (shrink)

In recent years, many philosophers of science have rejected the “value-free ideal” for science, arguing that non-epistemic values have a legitimate role to play in scientific inquiry. However, this philosophical position raises the question of how to distinguish between legitimate and illegitimate influences of values in science. In this paper, we argue that those seeking to address this “new” demarcation problem can benefit by drawing lessons from the “old” demarcation problem, in which philosophers tried to find a way of distinguishing (...) between science and non-science. Many of those who worked on this problem ultimately found that efforts to provide necessary and sufficient conditions for defining science failed, and most concluded that the best solution to the problem was to characterize scientific hypotheses, theories, and research programs in terms of some common norms. We suggest that those seeking to distinguish between legitimate and illegitimate value influences on science would do well to adopt a similar approach. Rather than attempting to establish necessary and sufficient conditions for identifying appropriate value influences, it will be more fruitful to evaluate scientific activities based on their adherence to a set of epistemic and ethical norms that can be implemented in scientific practice by means of rules, conventions, policies, and procedures.

Scholars working in science and technology studies have recently argued that we could learn much about the nature of scientific knowledge by paying closer attention to scientific ignorance. Building on the work of Robert Proctor, this article shows how ignorance can stem from a wide range of selective research choices that incline researchers toward partial, limited understandings of complex phenomena. A recent report produced by the International Assessment of Agricultural Knowledge, Science, and Technology for Development serves as the article’s central (...) case study. After arguing that the forms of selective ignorance illustrated in cases like this one are both socially important and difficult to address, I suggest several strategies for responding to them in a socially responsible manner.

Is voting a duty of democratic citizenship? This article advances a new argument for the existence of a duty to vote. It argues that every normative account of electoral representation requires universal turnout to function in line with its own internal normative logic. This generates a special obligation for citizens to vote in electoral representative contexts as a function of the role morality of democratic citizenship. Because voting uniquely authorizes office holding in representative democracies, and because universal turnout contributes powerfully (...) to representation being fair, to be a good citizen of such democracies requires one to vote. Whereas previous arguments for a duty to vote have invoked basic moral principles like fairness or a Samaritan duty of rescue, this account is based on citizens occupying a vital functional role within electoral representative institutions. This institutional duty solves the “specificity problem” of justifying a duty to vote better than competing accounts and also immunizes the duty to objections that there is no duty to vote when there are only bad choices and that there is a no duty to vote but rather duty to vote well. By emphasizing the tight connection between institutions and individual conduct, the role morality approach used here supplies a less abstract and more realistic framework than much previous research on the ethics of democratic citizenship and brings the debate closer to constitutive features of democratic politics.

The potential for financial conflicts of interest (COIs) to damage the credibility of scientific research has become a significant social concern, especially in the wake of high-profile incidents involving the pharmaceutical, tobacco, fossil-fuel, and chemical industries. Scientists and policy makers have debated whether the presence of financial COIs should count as a reason for treating research with suspicion or whether research should instead be evaluated solely based on its scientific quality. This paper examines a recent proposal to develop criteria for (...) evaluating the credibility of research without considering its source of funding. It concludes that proposals of this sort are likely to be either ineffective or impractical in many cases. Nevertheless, this does not imply that all research funded by those with an interest in the outcome must be placed under a cloud of suspicion; there are conditions under which research is at much more serious risk of being corrupted than in other cases, and attention to these conditions can guide productive responses to financial COIs.

The field of science communication is plagued by challenges. Communicators face the difficulty of responding to unjustified public skepticism over issues like climate change and COVID-19 while also acknowledging the fallibility and limitations of scientific knowledge. Our goal in this paper is to suggest a new model for science communication that can help foster more productive, respectful relationships among all those involved in science communication. Inspired by the pragmatist philosophy of John Dewey, we develop an experience model, according to which (...) science communication consists in people’s experiences with science and the meanings they develop from those experiences. Three principles are central to the model: experience is cumulative, context matters, and audiences have agency. We argue that this model has significant implications both for communication research and practice, which we illustrate by applying it to the phenomenon of vaccine hesitancy. We show how science communicators can help to identify and alleviate structural factors that contribute to skepticism as well as fostering opportunities for meaning making around shared experiences.

. The potential for financial conflicts of interest to influence scientific research has become a significant concern. Some commentators have suggested that the development of standardized study protocols could help to alleviate these problems. This paper identifies two problems with this solution: scientific research incorporates numerous methodological judgments that cannot be constrained by standardized protocols; and standardization can hide significant value judgments. These problems arise because of four weaknesses of standardized guidelines: incompleteness, limited applicability, selective ignorance, and ossification. Therefore, the (...) standardization of study designs should not serve as an alternative to addressing the interests and power relations that pervade science policy-making. Policy makers should take at least two steps to prevent powerful interest groups from co-opting standardized guidelines. First, their development and review should be made as transparent as possible and should be subjected to broadly-based deliberation. Second, standardized guidelines should be supplemented with efforts to scrutinize the conditions under which financial COIs tend to have the most worrisome effects so that additional steps can be taken to eliminate and mitigate those conditions.

Ethicists widely accept the notion that scientists have moral responsibilities to benefit society at large. The dissemination of scientific information to the public and its political representatives is central to many of the ways in which scientists serve society. Unfortunately, the task of providing information can often give rise to moral quandaries when scientific experts participate in politically charged debates over issues that are fraught with uncertainty. This paper develops a theoretical framework for an “ethics of expertise” (EOE) based on (...) the notion that scientists have responsibilities to provide information in a way that promotes autonomous decision-making on the part of the public and its representatives. Moreover, insofar as the principle of informed consent has developed in biomedical ethics as a way for physicians to promote autonomous decision-making on the part of their patients, this paper suggests that the informed-consent concept may suggest a set of criteria and guidelines that can help scientists to fulfill their similar ethical responsibilities to the public. In order to illustrate how the resulting EOE could provide practical guidance for scientific experts, the paper examines a case study involving the dissemination of information about the low-dose biological effects of toxic chemicals and carcinogens.

The discovery and ongoing investigation of microRNAs suggest important conceptual and methodological lessons for philosophers and historians of biology. This paper provides an account of miRNA research and the shift from viewing these tiny regulatory entities as minor curiosities to seeing them as major players in the post-transcriptional regulation of genes. Conceptually, the study of miRNAs is part of a broader change in understandings of genetic regulation, in which simple switch-like mechanisms were reinterpreted as aspects of complex cellular and genome-wide (...) processes. Among them are the activities of small RNAs, previously regarded as non-functional. Methodologically, the miRNA story suggests new ways of characterizing biological research that should prove helpful to philosophers of science who seek to develop more pluralistic, pragmatic models of scientific inquiry. miRNA research displays iterative movements between multiple modes of investigation that include not only the proposal and testing of hypotheses but also exploratory, technology-oriented and question-driven modes of research. As an exemplary story of scientific discovery and development, the miRNA case illustrates transitions from genetics to genomics and systems biology, and it shows how diverse configurations of research practice are related to major scientific advances.

This paper argues, first, that recent studies of experimentation, most notably by Deborah Mayo, provide the conceptual resources to describe scientific discovery's early stages as error-probing processes. Second, it shows that this description yields greater understanding of those early stages, including the challenges that they pose, the research strategies associated with them, and their influence on the rest of the discovery process. Throughout, the paper examines the phenomenon of "chemical hormesis" (i.e., anomalous low-dose effects from toxic chemicals) as a case (...) study that is important not only for the biological sciences but also for contemporary public policy. The resulting analysis is significant for at least two reasons. First, by elucidating the importance of discovery's earliest stages, it expands previous accounts by philosophers such as William Wimsatt and Lindley Darden. Second, it identifies the discovery process as yet another philosophical topic on which the detailed studies of the "new experimentalists" can shed new light. (shrink)

This paper examines how ethically significant assumptions and values are embedded not only in environmental policies but also in the language of the environmental sciences. It shows, based on three case studies associated with contemporary pollution research, how the choice of scientific categories and terms can have at least four ethically significant effects: influencing the future course of scientific research; altering public awareness or attention to environmental phenomena; affecting the attitudes or behavior of key decision makers; and changing the burdens (...) of proof required for taking action in response to environmental concerns. The paper argues that deliberative forums, research-ethics training, and conceptual work by environmental philosophers could all promote more ethically sensitive responses to these features of scientific language.

As it becomes more and more doubtful that the international community will take adequate steps to mitigate climate change, interest has grown in the possibility of engineering earth’s climate to prevent catastrophic levels of warming. Unfortunately, geoengineering schemes have the potential to create grave, unintended consequences. This paper explores the extent to which the precautionary principle (PP), which was developed as a guideline for responding to uncertainty in the policy sphere, can provide guidance for responding to the potential benefits and (...) hazards associated with geoengineering. The paper argues that there are so many different versions of the precautionary principle and so many potential strategies for geoengineering that there cannot be any single, simple relationship between the two. Nevertheless, it is possible to identify a set of lessons that many versions of the PP suggest for those considering geoengineering proposals. Moreover, examination of the geoengineering case provides an opportunity to reflect on a range of important situations—what this paper will call self-defeating scenarios—in which most versions of the PP provide limited guidance compared to other ethical principles.

In recent years, industry-funded research has come under fire because of concerns that it can be biased in favor of the funders. This article suggests that efforts by philosophers of science to analyze the concept of objectivity can provide important lessons for those seeking to evaluate and improve industry-funded research. It identifies three particularly relevant criteria for objectivity: transparency, reproducibility, and effective criticism. On closer examination, the criteria of transparency and reproducibility turn out to have significant limitations in this context, (...) but the criterion of effective criticism suggests some important strategies for improving the objectivity of industry-funded science.

In this response to Robert Hudson’s article, “Should We Strive to Make Science Bias-Free? A Philosophical Assessment of the Reproducibility Crisis,” we identify three ways in which he misrepresents our work: he conflates value-ladenness with bias; he describes our view as one in which values are the same as evidential factors; and he creates a false dichotomy between two ways that values could be considered in science for policy. We share Hudson’s concerns about promoting scientific reproducibility and reducing bias in (...) science, but we reject his view that the value-free ideal provides helpful guidance for addressing these issues.

Recent philosophical literature has highlighted the complexities of handling dissent in science. On one hand, scientific dissent can be very harmful, as when “merchants of doubt” strategically appeal to dissent in order to undermine important environmental and public-health initiatives. On the other hand, scientific dissent can also be beneficial when it helps to promote scientific objectivity, progress, and public engagement. Some authors have responded to this tension by suggesting criteria for distinguishing normatively appropriate and inappropriate dissent, while other authors have (...) suggested that it is more fruitful to alter the social context in which science operates in order to alleviate the negative effects of dissent over the long term. This paper proposes another approach that may be helpful for managing particularly challenging cases of scientific dissent. It argues that instances of scientific dissent often incorporate debates over value judgments, so many difficult cases of dissent can be navigated by: (1) identifying and highlighting those value judgments; and (2) managing those value judgments by drawing strategies from the extensive literature on values and science. The paper illustrates this approach by examining a case study of dissent over the treatment of long-term symptoms associated with Lyme disease. (shrink)

When communicating scientific information, experts often face difficult choices about how to promote public understanding while also maintaining an appropriate level of objectivity. We argue that one way for scientists and others involved in communicating scientific information to alleviate these tensions is to pay closer attention to the major frames employed in the contexts in which they work. By doing so, they can ideally employ useful frames while also enabling the recipients of information to “backtrack” to relatively uncontroversial facts and (...) recognize how these frames relate to their own values and perspectives. Important strategies for promoting this sort of backtracking include identifying the weaknesses of particular frames, preventing misunderstanding of them, differentiating well-supported findings from more speculative claims, and acknowledging major alternative frames.

Environmental ethicists have devoted considerable attention to discussing whether anthropocentric or nonanthropocentric arguments provide more appropriate means for defending environmental protection. This paper argues that philosophers, scientists, and policy makers should pay more attention to a particular type of anthropocentric argument. These anthropocentric indirect arguments defend actions or policies that benefit the environment, but they justify the policies based on beneficial effects on humans that are not caused by their environmental benefits. AIAs appear to have numerous appealing characteristics, and their (...) weaknesses do not provide compelling reasons to avoid them. Elucidating these arguments should inspire social scientists and philosophers to study the range of situations in which AIAs can be ethically and effectively employed and the extent to which they increase or diminish public support for environmentalism.

We argue that environmental aesthetics, and specifically the concept of aesthetic integrity, should play a central role in a public environmental philosophy designed to communicate about environmental problems in an effective manner. After developing the concept of the “aesthetic integrity” of the environment, we appeal to empirical research to show that it contributes significantly to people’s sense of place, which is, in turn, central to their well-being and motivational state. As a result, appealing to aesthetic integrity in policy contexts is (...) both strategically and morally advisable. To provide a concrete illustration of the ways in which such appeals can play a role in policy making, we examine a specific case study in which attention to aesthetic integrity contributed to blocking a proposed development. The case yields at least four lessons: (1) aesthetic integrity can be a practically effective framing device; (2) local deliberative settings are particularly conducive for addressing it; (3) it can serve as an umbrella under which multiple other issues can be brought to the fore; and (4) judgments about aesthetic integrity need not be entirely objective in order for them to play a productive role in the policy sphere.

In recent years, philosophers of science have taken renewed interest in pursuing scholarship that is “socially engaged.” As a result, this scholarship has become increasingly relevant to public policy. In order to illustrate the ways in which the philosophy of science can inform public policy, this chapter focuses specifically on environmental research and policy. It shows how philosophy can assist with environmental policy making in three ways: clarifying the roles of values in policy-relevant science; addressing scientific dissent, especially in response (...) to “hot-button” policy issues; and responding thoughtfully to scientific uncertainty.

Relatively few thinkers have attempted to develop a systematic ‘ethics of expertise’ (EOE) that can guide scientists and other technical experts in providing information to the public. This paper argues that the prima facie duty to disseminate information in a manner that does not damage the self-determination of decision makers could fruitfully serve as one of the core principles of an EOE. Moreover, this duty can be fleshed out in promising ways by drawing on the concept of informed consent, which (...) guides medical clinicians in preserving the self-determination of their patients. The paper applies the resulting ethical framework to recent policy discussions about hydrogen fuel-cell (HFC) vehicles, both because they have received a good deal of research funding and because their merits have been hotly debated. It concludes that technical experts providing information about HFC vehicles should be especially cognizant of three issues: (1) important alternatives to hydrogen technology that need to be addressed, (2) major false beliefs that should be prevented or corrected, and (3) significant framing effects that could influence the recipients of information.

: This paper examines the epistemological warrant for a toxicological phenomenon known as chemical hormesis. First, it argues that conceptual confusion contributes significantly to current disagreements about the status of chemical hormesis as a biological hypothesis. Second, it analyzes seven distinct concepts of chemical hormesis, arguing that none are completely satisfactory. Finally, it suggests three ramifications of this analysis for ongoing debates about the epistemological status of chemical hormesis. This serves as a case study supporting the value of philosophical methodologies (...) such as conceptual clarifica-tion for addressing contemporary scientific disputes, including policy-related scientific disputes that may be heavily in(integral)uenced by social and political factors.

It is widely recognized that endocrine disrupting compounds, such as Bisphenol A, pose challenges for traditional paradigms in toxicology, insofar as these substances appear to have a wider range of low-dose effects than previously recognized. These compounds also pose challenges for ethics and policymaking. When a chemical does not have significant low-dose effects, regulators can allow it to be introduced into commerce or the environment, provided that procedures and rules are in place to keep exposures below an acceptable level. This (...) option allows society to maximize the benefits from the use of the chemical while minimizing risks to human health or the environment, and it represents a compromise between competing values. When it is not possible to establish acceptable exposure levels for chemicals that pose significant health or environmental risks, the most reasonable options for risk management may be to enact either partial or complete bans on their use. These options create greater moral conflict than other risk management strategies, leaving policymakers difficult choices between competing values. (shrink)

Economist Frank Knight drew a distinction between decisions under risk and decisions under uncertainty. Despite the significance of this distinction for decision theory, we argue that there has been inadequate attention to the difficulties involved in classifying decision situations into these categories. Using the risk assessment of carbon nanotubes as an example, we show that it is often unclear whether there is adequate information to classify a decision situation as being under risk as opposed to uncertainty. We conclude by providing (...) two suggestions for responding to these difficulties: treating decisions as real-world experiments; and promoting broadly based deliberation about quantitative information.
