This paper reflects on the origins and subsequent reception of the paper "Ontological Gerrymandering: The anatomy of social problems explanations", published in 1985. It describes the circumstances of my turning up at McGill University as a Visiting Professor in Sociology and meeting Dorothy, then a graduate student and the TA assigned to an undergraduate course on Social Problems which I was asked to teach. The paper reflects on the twin benefits: of an interloper, from Europe and from Science and Technology (...) Studies (STS), entering the exotic and heady fray of North American social problems; and of Dorothys steady and resolute guidance in introducing me to a new field. The paper suggests some reasons for the endurance of the papers arguments, more than 35 years after its publication, drawing on some parallel developments in Social Problems and STS. It asks why has there been rather little mutual interaction between these disciplines, given their common concern with questions, among others, about values, effects and interventions in academic scholarship. The paper concludes that many more of us might have done well to pursue the path of strident agnosticism. (shrink)

Safer sex has emerged as a collection of practices and ideas deployed to combat the spread of AIDS. Prevention messages and rituals of safer sex each rely on constructing a potential user's relationship to latex devices. This article is based on an analysis of twenty-seven interviews conducted with people in the sex trade. Since sex workers make it their business to exchange sexual services for economic compensation, many have become extremely sophisticated in their innovations and expressions of eroticism using safer (...) sex techniques. Sex workers are one of a group of key knowledge producers focused on safer sexual practices. Their worlds are metaphoric laboratories for empiri cal studies of emergent sexual practices. This article describes the innovations of the use of technologies of safer sex and the configuration of users. (shrink)

The understanding of science by members of the public has been of increasing concern to social scientists. This article argues that such understanding, or the ostensible lack of it, is structured by discourses that address science both as an abstract entity or principle and as an activity directed at specific phenomena or problems. Drawing upon a wide range of interviews about various sources of ionizing radiation, it is suggested that understanding is tied to questions of social identity that encompass relations (...) of differentiation from and identification with science and the institutions in which it is embedded.

Surgical training has traditionally involved a lengthy apprenticeship to a series of master surgeons, who teach medical students and residents the techniques of surgery while allowing them to work on patients in the operating room. This article examines surgical training as a structured environment that prepares students for the embodied lessons taught by a surgeon. It argues that even the most seemingly mechanical of surgical techniques contains social lessons when taught by a surgeon within the rich environment of the operating (...) room. (shrink)

This paper aims to explore disciplinary variation in valuation practices by comparing the way research groups accumulate credibility across four epistemic cultures. Our analysis is based on case studies of four high-performing research groups representing very different epistemic cultures in humanities, social sciences, geosciences and mathematics. In each case we interviewed about ten researchers, analyzed relevant documents and observed a couple of meetings. In all four cases we found a cyclical process of accumulating credibility. At the same time, we found (...) significant differences in the manifestation of the six main resources that are part of the cycle, the mechanisms of conversion between these resources, the overall structure and the average speed of the credibility cycle. The different ways in which the groups use data and produce arguments affect the whole cycle of accumulating credibility. In some cultures, journal publications are the main source of recognition, but in others one can earn significant amounts of recognition for conference contributions or service to the academic community. Moreover, the collaboration practices in the respective fields strongly influence the connection between arguments and publications. In cultures where teams of researchers collaboratively produce arguments, it is more strongly embedded in the process of writing publications. We conclude that the credibility cycle can only be used as an analytical tool to explain the behavior of researchers or research groups when taking differences across epistemic cultures into account.

To whom, if anyone, are the writings of philosophers of science relevant? There are three potential groups of people: Philosophers, Scientists, and Interested Citizens, within and beyond the academy. I argue that our discipline is potentially relevant to all three, but I particularly press the claims of the Interested Citizens. My essay is in dialogue with a characteristically insightful lecture given thirty years ago by Arthur Fine. Addressing the Philosophy of Science Association as its president, Fine argued that general philosophy (...) of science was dead, and that all the action lay in the philosophy of the special sciences. I try to identify what was correct about Fine’s diagnosis, while supplementing his message by describing fruitful projects that have since emerged. I also hope to share his subversive spirit.

H. Collins has challenged the empiricist understanding of experimentation by identifying what he thinks constitutes the experimenter’s regress: an instrument is deemed good because it produces good results, and vice versa. The calibration of an instrument cannot alone validate the results: the regressive circling is broken by an agreement essentially external to experimental procedures. In response, A. Franklin has argued that calibration is a key reasonable strategy physicists use to validate production of results independently of their interpretation. The physicists’ arguments (...) about the merits of calibration are not coextensive with the interpretation of results, and thus an objective validation of results is possible. I argue, however, that the in-situ calibrating and measurement procedures and parameters at the Large Hadron Collider are closely and systematically interrelated. This requires empiricists to question their insistence on the independence of calibration from the outcomes of the experiment and rethink their position. Yet this does not leave the case of in-situ calibration open to the experimenter’s regress argument; it is predicated on too crude a view of the relationship between calibration and measurement that fails to capture crucial subtleties of the case.

This article argues that all knowledge is inherently local and that localness provides the basis for comparison between indigenous scientific traditions or knowledge production systems. As collective bodies of knowledge, many of the significant differences between knowledge production systems lie in the work involved in creating assemblages from differing practices. Much of the work can be seen in the social strategies and technical devices employed in creating equivalences and connections whereby otherwise heterogeneous and isolated knowledges are enabled to move in (...) space and time from the local site and moment of their production and application to other places and times. In this way contemporary technosciences are compared with the knowledge systems of the medieval mastermasons, the Anasazi, the Inca, the Australian Aborigines and the Pacific navigators. (shrink)

The ArgumentIn the controversy in 1989 over the reported achievement of cold nuclear fusion, parts of the physics and chemistry communities were opposed in both a theoretic and a professional competition. Physicists saw the chemists' announcement as an incursion into territory allocated to their own discipline and strove to restore the interdisciplinary boundaries that had previously held. The events that followed throw light on the manner in which scientists' knowledge claims and metascientific beliefs are affected by their membership of disciplinary (...) communities. In particular, the controversy offers evidence for a constructivist reinterpretation of the “division of nature into levels,” which is customarily held to underpin the division of science into disciplines.

In contrast to earlier accounts of the epistemic significance of narrative, it is argued that narrative is important in natural scientific knowledge. To recognize this, we must understand narrative not as a literary form in which knowledge is written, but as the temporal organization of the understanding of practical activity. Scientific research is a social practice, whereby researchers structure the narrative context in which past work is interpreted and significant possibilities for further work are projected. This narrative field displays a (...) constant tension between a need for a coherent, shared understanding of the field and the incoherence threatened by divergent projects and interpretations. The account has three parts. First, a summary of the general account of the narrative intelligibility of action which underlies the proffered view of narrative in science. This account is then applied to understanding how scientific work acquires significance, and how the scientific literature is constructed and read. Finally, it is shown how this account should transform our understanding of the unity of science, and it is suggested how it can help undercut various realist and anti?realist interpretations of scientific knowledge, while also challenging the ironic stance which many recent sociologists adopt toward the global legitimation of science attempted by many philosophers.

This article considers the `Strong Programme' account of scientific knowledge from a fresh perspective. It argues that insufficient attention has been paid to the Strong Programme's monistic intent, that is, its aim to unify considerations of instrumental adequacy and social interests in explanations of the development of scientific knowledge. Although sharing the judgment of many critics that the Strong Programme approach is flawed, the article diverges from standard criticisms by suggesting that the best alternative is not a dualistic framework but (...) a more adequate monistic approach. Key Words: Strong Programme • interests • monism • finitism • classification. (shrink)

: In the last two decades, scientists, government officials, and science policy experts have expressed concerns about the increasing role of financial interests in research. Many believe that these interests are undermining research by causing bias and error, suppression of results, and even outright fraud. This paper seeks to shed some light on this view by (1) explicating the concept research bias, (2) describing some ways that financial interests can cause research biases, and (3) discussing some strategies for mitigating or (...) managing the influence of financial interests. These strategies include (a) using government funds to counter-balance privately funded research, (b) increasing public input into government funding decisions, (c) disclosing and managing conflicts of interest in research, (d) auditing data, (e) expanding access to data. Since it is neither possible nor desirable to eliminate financial interests from research, the wisest policy is to manage and counter-balance these interests for the good of science and society.

Since the practice turn, the role technologies play in the production of scientific knowledge has become a prominent topic in science studies. Much existing scholarship, however, either limits technology to merely mechanical instrumentation or uses the term for a wide variety of items. This article argues that technologies in scientific practice can be understood as a result of past scientific knowledge becoming sedimented in materials, like model organisms, synthetic reagents or mechanical instruments, through the routine use of these materials in (...) subsequent research practice. The proposed theoretical interpretation of technology is examined through a case where a model organism—Drosophila melanogaster—acted as a technology for investigating a contested biological effect of a mechanical instrument: Hermann J. Muller’s experiments on X-ray mutagenicity in the 1920s. The article reconstructs how Muller employed two synthetic Drosophila stocks as tests for measuring X-rays’ capacity to cause genetic aberration. It argues that past scientific knowledge sedimented in the Drosophila stocks influenced Muller’s perception of X-ray-induced mutation. It further describes how Muller’s concept of X-ray mutagenicity sedimented through the adoption of X-ray machines as a ready-made resource for producing mutants by other geneticists, for instance George Beadle and Edward Tatum in their experiments on Neurospora crassa, despite ongoing disputes surrounding Muller’s conclusions. Technological sedimentation is proposed as a potential explanation why sedimentation and disputation may often coexist in the history of science. (shrink)

This article explores the practice of simulation modeling by investigating how parameterizations are constructed and integrated into existing frameworks. Parameterizations are simplified process descriptions adapted for simulation models. On the basis of a study of meteorological research, the article presents predictive and representative construction as two different ways of developing parameterizations and the trade-offs involved in this work. Because the overall aim in predictive construction is to improve weather forecasts, the most practical solutions are chosen over the best theoretical solutions. (...) In representative construction, the situation is reversed, but while discourse focuses on theory and models, the everyday work is often tied to computer programs. These different ways of construction work are closely related to the role of the simulation models as epistemic or technical objects, and this characterization is also used to compare the results with previous research.

Social studies of science and technology are dominated by action and macro approaches. This has led to a neglect of institutions and institutional arrangements at the meso level, which are important, in particular to the student of technology. The transfer of concepts and methods from social studies of science to technology studies has conserved this lack of concern with the meso level. This article suggests a more critical evaluation of this transfer, along with a review of the now popular assumption (...) of a high degree of similarity between science and technology. Two case studies show how meso-level considerations are important to an understanding of the nature of technological innovation and illustrate the lack of similarity between scientific and technological development.

Numerical simulations have come to be widely used in scientific work. Like experiments, simulations generate large quantities of numbers that require analysis and constant concern with uncertainty and error. How do simulationists convince themselves, and others, about the credibility of output? The present analysis reconstructs the perspectives related to performing numerical simulations, in general, and the situations in which simulationists deal with uncertain output, in particular. Starting from a distinction between idealized and realistic simulations, the paper presents the principal methods (...) of evaluation in relation to these practices and how different audiences expect different methods. One major challenge in interpreting output data is to distinguish between “real” and “numerical” effects. Within the practice of idealized simulations, simulationists hold the underlying model accountable for results that manifest “real” effects, but because “numerical” and “real” effects cannot be distinguished on the basis of what they derive from, attempted causal explanations are rather justifications for their conclusions. At the same time, simulationists’ explanations are part and parcel of their contradictory perspectives, according to which they believe in simulations largely due to the underlying model, while painfully recognizing everything they have to add to make computations doable on the basis of this model.

In 1869, Johann Friedrich Miescher discovered a new substance in the nucleus of living cells. The substance, which he called nuclein, is now known as DNA, yet both Miescher’s name and his theoretical ideas about nuclein are all but forgotten. This paper traces the trajectory of Miescher’s reception in the historiography of genetics. To his critics, Miescher was a “contaminator,” whose preparations were impure. Modern historians portrayed him as a “confuser,” whose misunderstandings delayed the development of molecular biology. Each of (...) these portrayals reflects the disciplinary context in which Miescher’s work was evaluated. Using archival sources to unearth Miescher’s unpublished speculations—including an analogy between the hereditary material and language, and a speculation that a series of asymmetric carbon atoms could account for hereditary variation—this paper clarifies the ways in which the past was judged through the lens of contemporary concerns. It also shows how organization, structure, function, and information were already being considered when nuclein was first discovered nearly 150 years ago. (shrink)

Cultural anthropologists and sociobiologists developed initially incommensurable approaches to explaining cooperation and altruism in human societies. When understood as complex cultural adaptations, however, scientific research programs are subject to piecemeal changes in the research programs driving scientific research. The emergence of new research programs in cultural evolution and group selection resulted. This transformation is examined with a focus on explanations for the origin and maintenance of human inequality. The transmission, modification, and selection of the complex cultural packages underlying egalitarianism and (...) hereditary inequality challenge both the focus on biological roots of hierarchy and the autonomous construction of cultures.

We propose a new account of calibration according to which calibrating a technique shows that the technique does what it is supposed to do. To motivate our account, we examine an early twentieth-century debate about chlorophyll chemistry and Mikhail Tswett’s use of chromatographic adsorption analysis to study it. We argue that Tswett’s experiments established that his technique was reliable in the special case of chlorophyll without relying on either a theory or a standard calibration experiment. We suggest that Tswett broke (...) the experimenters’ regress by appealing to material facts in the common ground for chemists at the time. (shrink)

Relativism is often motivated in terms of certain types of disagreement. In this paper, we survey the philosophical debates over two such types: faultless disagreement in the case of gustatory conflict, and fundamental disagreement in the case of epistemic conflict. Each of the two discussions makes use of a implicit conception of judgement: brute judgement in the case of faultless disagreement, and rule-governed judgement in the case of fundamental disagreement. We show that the prevalent accounts work with unreasonably high levels (...) of idealization. We defend two claims. First, philosophical discussions of disagreement need to be de-idealized. Second, once a less idealized account of disagreement is available, both our conception of judgement and our understanding of relativism need to be revised. Our example is a case study in the Sociology of Scientific Knowledge: Steven Shapin and Simon Schaffer’s classic Leviathan and the Air-Pump. This case study gives a less idealized account of disagreement that conceptualizes judgements as situated. We argue that this conception can and should be applied to cases of gustatory and epistemic disagreement. The payoff will be a reformulation of relativism in terms of rationally resolvable yet contingent disagreements. (shrink)

Sociologists, philosophers and historians of science are gradually recognizing the importance of visual representation. This is part of a more general movement away from a theory-centric view of science and towards an interest in practical aspects of observation and experimentation. Rather than treating science as a matter of demonstrating the logical connection between theoretical and empirical statements, an increasing number of investigations are examining how scientists compose and use diagrams, graphs, photographs, micrographs, maps, charts, and related visual displays. This paper (...) focuses on diagrams in biology, and tries to demonstrate how diagrams are an integral part of the production of scientific knowledge. In order to disclose some of the distinctive practical and analytical uses of diagrams, the paper contrasts the way diagrams and photographs are used in biological texts. Both diagrams and photographs are shown to be “constructions” that separately and together mediate the investigation of scientific phenoman. (shrink)

: This essay addresses the difficulties that sociology as a discipline continues to experience in grasping the relations between technology, science and the social. I argue that these difficulties stem from a resolute centering of sociology on the social, which follows a generically Durkheimian blueprint. I elaborate a response to these difficulties which derives from recent lines of work in science and technology studies, and which entails a decentering of the social relative to the material and the conceptual, in terms (...) of both objects of analysis and explanatory formats. In order to display the direct sociological relevance of this approach, I move to the macro level, developing the conceptual apparatus of a decentered social theory via the discussion of a historical example of major sociological significance—the systematic gearing together of scientific research, technological innovation and industrial production that originated in the synthetic dye industry in the second half of the nineteenth century. Besides the interest of the topic itself, the aim is thus to exemplify in some detail what a decentered sociology might look like, both empirically and conceptually. (shrink)

A popular trend in the sciences of the mind is to understand cognition as embodied, embedded, enactive, ecological, and so on. While some of the work under the label of “embodied cognition” takes for granted key commitments of traditional cognitive science, other projects coincide in treating embodiment as the starting point for an entirely different way of investigating all of cognition. Focusing on the latter, this paper discusses how embodied cognitive science can be made more reflexive and more sensitive to (...) the implications that our views of cognition have for how we understand scientific practice, including our own theorizing about cognition. Inspired by the “strong programme” in the sociology of scientific knowledge, I explore the prospect of an analogously “strong” program in embodied cognitive science. I first draw from Dewey’s transactional notion of “situation” to identify a broad sense in which embodied cognitive science takes cognition, as an embodied phenomenon, to be _situated_. I then sketch a perspective I call _situated reflexivity_, which extends the Deweyan analysis to understand scientific practice in the same terms, and thereby illustrates what research in line with a strong program in embodied cognitive science can look like. This move, I propose, has the potential of setting up a new inquiry situation that makes more salient the embodiment of scientific practice and that, through this, can help organize our own embodied cognitive activities as we try to make sense of scientific work, including our own.

All life on Earth shares the same ancestor, the most primitive form of life that arose, in still unknown circumstances, more than 3.5 billion years ago. At least this is what is commonly assumed. Astrobiologists have revisited this assumption and advanced the hypothesis of the existence of a “shadow biosphere” on Earth: a parallel tree of life whose instances, being different at the molecular level to the kind of life we are used to, would remain hidden from view. In this (...) paper, I take the emergence of the so-called shadow biosphere hypothesis and the controversial discovery of GFAJ-1, a microbe thriving in the arsenic-rich waters of Mono Lake, as an entry point to look into the strategic role of non-knowledge claims. I juxtapose the Latourian black-box, that is, those undiscussed technoscientific artifacts that are taken for granted in scientific practice, with the shadowy nature of non-knowledge claims in order to pay closer attention to the contingent, active, performative, and always social nature of the making of what is unknown. I conclude this paper by claiming that in the negotiation of what is unknown, emerging disciplines position themselves within the larger scientific community. (shrink)

The ArgumentThis paper is a study of the role of language in scientific activity. It recommends that language be viewed as a community's means of patterning its affairs. Language represents where the boundaries of the community are and who is entitled to speak within it, and it displays the structures of authority in the community. Moreover, language precipitates the community's view of what the world is like, such that linguistic usages can be taken as referring to that world. Thus, language (...) connects on the one side to a community's practical life, and, on the other, to the reality on which it “reports.”The example treated is Robert Boyle's view of the language proper for experimental practice, and his arguments against the value and legitimacy of mathematical representations within the experimental community. Boyle argued that the use of mathematics was inappropriate because (i) it would restrict the number of potential participants; (ii) it would give rise to unwarranted expectations of the certainty and accuracy to be expected of real physical inquiries; (iii) it would suggest views of natural law and God's relations with the natural world which were incorrect and possibly dangerous; and because (iv) the world upon which the experimentalist operated was not such as was represented by mathematical idealizations. I try to establish that decision about the appropriate language for the experimental community was a moral choice. (shrink)

This paper addresses a problem in reporting scientific research. The problem is how to distinguish between justifiable and unjustifiable data selection. Robert Millikan is notorious for an infamous remark that he used all his data when in fact he had used a selection. On this basis he has been accused of fraud. There is a tension here — historians and his defenders see his selection as understandable and legitimate, while current statements about the Responsible Conduct of Research imply his selection (...) was illegitimate. This paper discusses two main issues that arise in assessing his conduct, whether he was intentionally misleading and whether he actually did mislead the scientific community about some facts of nature. It is argued that he was not intentionally misleading, and that it is unlikely that he misled the scientific community. (shrink)

The present thesis is based on a scientifically-informed, contextualized and historicized reading of Ludwik Fleck. In addition to his monograph, the material studied includes his additional philosophical writings, his internationally-published scientific articles and two, thus-far-unstudied postwar Polish papers related to his Buchenwald experiences. The sources provided by Fleck have been traced back to the time of their origin. Based on the above material, it is argued that, rather than relativizing science and deeply influencing Kuhn, Fleck, attempting to participate in the (...) current debates, is an ardent proponent of science, offering an internal account of its pursuit that accords with his oft-contested epistemic concepts, e.g., Denkzwang, Sinnsehen and Kopplungen. The exposure of his description of the Wassermann reaction discloses a highly selective reading of the sources available at the time, but also reveals its relation to the current debate on Einzelwissenschaften, or the standing of new emerging disciplines versus age-old ones, all occasioned by the remarkable progress of science that has also affected philosophy. The divide between philosophers and scientists on the philosophical implications of modern physics is exposed, as is Fleck’s heuristic use of the latter topic in his epistemology. A more realistic account of his often-valued scientific accomplishments is provided. It is argued that the modern interpretation or received humanist view of Fleck is based on the opposition, at the time Fleck’s monograph was rediscovered, of STS writers to a scientifically-informed reading of his texts. An additional corrective to the received view of Fleck is found in some of his postwar Polish papers related his Buchenwald experiences. The latter might also provide an answer to some of the contradictions inherent in the modern mythology surrounding Fleck. In amply exposing the precarious situation of the time, and the complexity of the ethical issues at stake, Fleck’s papers in fact generate age-old philosophical questions still worth contemplating.

How are data science systems made to work? It may seem that whether a system works is a function of its technical design, but it is also accomplished through ongoing forms of discretionary work by many actors. Based on six months of ethnographic fieldwork with a corporate data science team, we describe how actors involved in a corporate project negotiated what work the system should do, how it should work, and how to assess whether it works. These negotiations laid the (...) foundation for how, why, and to what extent the system ultimately worked. We describe three main findings. First, how already-existing technologies are essential reference points to determine how and whether systems work. Second, how the situated resolution of development challenges continually reshapes the understanding of how and whether systems work. Third, how business goals, and especially their negotiated balance with data science imperatives, affect a system’s working. We conclude with takeaways for critical data studies, orienting researchers to focus on the organizational and cultural aspects of data science, the third-party platforms underlying data science systems, and ways to engage with practitioners’ imagination of how systems can and should work.

Works in science and technology studies have repeatedly pointed to the importance of the visual in scientific practice. STS has also explicated how embodied practice generates scientific knowledge. I aim to supplement this literature by pointing out how sound and hearing are integral aspects of experimentation. Sound helps define how and when lab work is done, and in what kinds of spaces. It structures experimental experience. It affords interactions between researchers and instruments that are richer than could be obtained with (...) vision alone. And it is a site for tacit knowledge, providing a resource for the replication of results, and the transmission of knowledge, and the construction of social boundaries within instrumental communities.

This is a brief, personal retrospective on developments in the treatment of scientific discovery by philosophers, since about 1970.

The philosophical tradition of phenomenology, with its focus on human bodily perception, can be used to explore the ways scientific instrumentation shapes a user’s experience. Building on Don Ihde’s account of technological embodiment, I develop a framework of concepts for articulating the experience of image interpretation in science. These concepts can be of practical value to the analysis of scientific debates over image interpretation for the ways they draw out the relationships between the image-making processes and the rival scientific explanations (...) of image content. As a guiding example, I explore a contemporary debate over images of the surface of Mars which reveal a landmass that resembles river delta formations on Earth, and which thus has important implications for the history of Martian climate and water flow. The phenomenological framework I develop can be used to help evaluate the different interpretations on offer for these images, and to analyze the roles in this discussion played by spacecraft equipped with cameras and laser and thermal imaging devices.

During the last few years, several sociological accounts of scientific consensus appeared in which a radically skeptical view of cognitive consensus in science was advocated. Challenging the traditional realist conception of scientific consensus as a sui generis social fact, the radical skeptics claim to have shown that the traditional historical sociologist's supposedly definitive account of scientific consensus is only a linguistic chimera that easily can be deconstructed by the application of different interpretive schema to the given data. I will argue (...) in this article that such an idealistic conception of scientific consensus results from the radical skeptics' failure to take into account the following three factors that are central to the historical sociologist's narrative account of consensus formation: the "judgmental" character of the reconstruction of scientists' beliefs, the hierarchical nature of the consensus change in science, and the importance of the "temporal dimension" in the explanation of scientific consensus formation. To substantiate these three points, I will draw extensively on two recent historical-sociological studies of scientific consensus formation. (shrink)

Fire safety expertise was in great demand following the Grenfell Tower fire in London in June 2017. The government established a review of building regulations and an expert panel to inform its responses to Grenfell, and many other relevant organisations also formed their own expert panels. However, expert knowledge in fire safety is a highly contested domain, with knowledge claims based on differing sources. Fire fighters can claim expertise based on their experience of fighting fires, scientists and science-based engineers can (...) claim expertise from experimentation, and those who create and enact regulations can claim expertise in what can termed ’codespeak’—the language of regulation. Although distanced from fundamental empirical experience of fire, codespeak is powerful because of its relative clarity and certainty, and legal status. Building users also bring their own form of ‘local’ expertise—they have first-hand experience of the practicalities of the solutions wrought by the other experts. Policy-makers thus face many competing forms of expert advice on fire safety, and their ability to judge what is most relevant in any particular case rests on the existence of a sufficient range and depth of in-house government expertise.
