Drawing on the SAGE minutes and other documents, I consider the wider lessons for norms of scientific advising that can be learned from the UK’s initial response to coronavirus in the period January-March 2020, when an initial strategy that planned to avoid total suppression of transmission was abruptly replaced by an aggressive suppression strategy. I introduce a distinction between “normatively light advice”, in which no specific policy option is recommended, and “normatively heavy advice” that does make an explicit recommendation. (...) I argue that, although scientific advisers should avoid normatively heavy advice in normal times in order to facilitate democratic accountability, this norm can be permissibly overridden in situations of grave emergency. SAGE’s major mistake in early 2020 was not that of endorsing a particular strategy, nor that of being insufficiently precautionary, but that of relying too heavily on a specific set of “reasonable worst-case” planning assumptions. I formulate some proposals that assign a more circumscribed role to “worst-case” thinking in emergency planning. In an epilogue, I consider what the implications of my proposals would have been for the UK’s response to the “second wave” of late 2020. (shrink)

In this paper, we reflect on our experience as science and technology studies researchers who were members of the working group that produced A Synthetic Biology Roadmap for the UK in 2012. We explore how this initiative sought to govern an uncertain future and describe how it was successfully used to mobilize public funds for synthetic biology from the UK government. We discuss our attempts to incorporate the insights and sensibilities of STS into the policy process and why (...) we chose to use the concept of responsible research and innovation to do so. We analyze how the roadmapping process, and the final report, narrowed and transformed our contributions to the roadmap. We show how difficult it is for STS researchers to influence policy when our ideas challenge deeply entrenched pervasive assumptions, framings, and narratives about how technological innovation necessarily leads to economic progress, about public reticence as a roadblock to that progress, and about the supposed separation between science and society. We end by reflecting on the constraints under which we were operating from the outset and on the challenges for STS in policy. (shrink)

This paper analyses how the Cold War influenced the discourses on basic research and on Science and Technology Policies of some leaders of the Argentine research community. It explores two key intersections to study the Cold War: the first between politics and policies; the second between the global and the regional/national. The basic assumption is that, just as there was no one Cold War, specific regional and national traits lent specific meanings to basic research. In dialogue with the literature (...) on Latin American history of STPs, on Cold War and on the conceptual history of science, the paper identifies three discursive configurations around S&T: the first refers to the semi-peripheral scientific context; the second is associated with the ‘democracy-totalitarianism’ dichotomy, and the third is linked to the ‘development-dependence’ dichotomy. Finally, the paper also traces some connections between these discourses and the institutional models proposed by different key actors of the research community to implement STPs. (shrink)

This second research paper on science education in Māori‐medium school contexts complements an earlier article published in this journal (Stewart, 2005). Science and science education are related domains in society and in state schooling in which there have always been particularly large discrepancies in participation and achievement by Māori. In 1995 a Kaupapa Māori analysis of this situation challenged New Zealand science education academics to deal with ‘the Māori crisis’ within science education. Recent NCEA results (...) suggest Pūtaiao (Māori‐medium Science) education, for which a national curriculum statement was published in 1996, has so far increased, rather than decreased, the level of inequity for Māori students in science education. What specific issues impact on this lack of success, which contrasts with the overall success of Kura Kaupapa Māori, and how might policy frameworks and operational systems of Pūtaiao need to change, if better achievement in science education for Māori‐medium students is the goal? A pathway towards further research and development in this area is suggested. (shrink)

Does science have a place when it comes to making public policy? The answer might not be as simple as many people think. Ideally, scientists discover facts, and those facts inform policy. But policy undermines the open-ended nature of scientific inquiry, and scientists end up representing an agenda rather than presenting objective truths to be used to make decisions that impact the public. Through a variety of perspectives, this volume explores who wins and who loses when (...) science and politics mix. (shrink)

This policy brief explores important trends for the future of science for policy in Europe and the challenges and opportunities that they present for the development of science for policy ecosystems in the European Union. On the background of an increasing prominence of science in public debates and an increasing willingness of governments to mobilize scientific advice, the policy brief explores trends that shape the practices and processes of information exchange between knowledge actors (...) and policy-makers with the intention to produce scientifically informed policies in Europe, and frame important challenges and opportunities for science for policy ecosystems in the EU.

“Follow the science” was commonly repeated during debates on COVID-19-related policy. The phrase “follow the science” raises questions that are central to our theories of knowledge and the application of scientific knowledge to maximize the wellbeing of our society. The purpose of this study was to (1) perform a scoping review of literature discussing “follow the science” and COVID-19, and (2) consider “follow the science” in the context of pediatric health. A comprehensive search of 14 (...) databases was performed on May 23, 2023. Articles were included if they used terms such as “follow the science”, “follow the scientists”, “listen to science” or “listen to scientists”, and discussed COVID-19. There were 24 articles included in the final review. Existing literature on “follow the science” (1) differentiates between scientific knowledge and policy decisions; (2) emphasizes the importance of social sciences in policy making; (3) calls for more transparency in the knowledge synthesis and policy generating process; and (4) finds that scientific advisors see their role as advising on science rather than policy decision making. There was no definitional, epistemological, or philosophical intellectual defense of “follow the science” in the peer reviewed literature. Policy requires (1) reliable data and (2) agreement on what to do considering those empirical facts by appealing to values, ethics, morality, and law. A review of school shutdowns is used as an example of the inadequacy of “follow the science” as a guiding principle for public policy. (shrink)

This article discusses the relationship between a deconstructivist method in science and technology studies and the more recent moves towards a reconstructivist engagement with science and science policy making. Drawing on examples from the author's own research, the article identifies three forms of engagement and their relative utility and limitations. The article argues that these are typical of STS work that seeks direct engagement with science policy making and which could form the basis for (...) a more "serviceable STS" that retains its critical and independent perspective on science. The paper concludes by arguing that the analysis has important implications for the ways in which STS expertise can articulate with science policy making. (shrink)

This corrects a single typographical error in the article "Science and policy in extremis: the UK’s initial response to COVID‑19".

This article argues that, in public and policy contexts, the ways in which many scientists talk about uncertainty in simulations of future climate change not only facilitates communications and cooperation between scientific and policy communities but also affects the perceived authority of science. Uncertainty tends to challenge the authority of chmate science, especially if it is used for policy making, but the relationship between authority and uncertainty is not simply an inverse one. In policy (...) contexts, many scientists are compelled to talk about uncertainty but do not wish to imply that uncertainty is a serious challenge to the authority of scientific knowledge or to its substantial use in policy making. "Boundary-ordering devices, " the contextual discursive attempts to reconcile uncertainty and authority in science, depend critically for their success on their "dual" interpretation: at a general level across a boundary and differently on either side of it. The authors empirically identify a range of such boundary-ordering devices in the climate field. (shrink)

The social sciences playa variety of multifaceted roles in the policymaking process. So varied are these roles, indeed, that it is futile to talk in the singular about the use of social science in policymaking, as if there were one constant relationship between two fixed and stable entities. Instead, to address this issue sensibly one must talk in the plural about uses of dif ferent modes of social scientific inquiry for different kinds of policies under various circumstances. In some (...) cases, the influence of social scientific research is direct and tangible, and the connection between the find ings and the policy is easy to see. In other cases, perhaps most, its influence is indirect-one small piece in a larger mosaic of politics, bargaining, and compromise. Occasionally the findings of social scientific studies are explicitly drawn upon by policymakers in the formation, implementation, or evaluation of particular policies. More often, the categories and theoretical models of social science provide a general background orientation within which policymakers concep tualize problems and frame policy options. At times, the in fluence of social scientific work is cognitive and informational in nature; in other instances, policymakers use social science primarily for symbolic and political purposes in order to le gitimate preestablished goals and strategies. Nonetheless, amid this diversity and variety, troubling general questions persistently arise. (shrink)

This book explains the notational system NUSAP (Numeral, Unit, Spread, Assessment, Pedigree) and applies it to several examples from the environmental sciences.

The aim of this article is to question the epistemic presuppositions of applying behavioural science in public policymaking. Philosophers of science who have examined the recent applications of the behavioural sciences to policy have contributed to discussions on causation, evidence, and randomised controlled trials. These have focused on epistemological and methodological questions about the reliability of scientific evidence and the conditions under which we can predict that a policy informed by behavioural research will achieve the policymakers’ (...) goals. This paper argues that the philosophical work of Helen Longino can also help us to have a better and fuller understanding of the knowledge which the behavioural sciences provide. The paper advances an analysis of the knowledge claims that are made in the context of policy applications of behavioural science and compares them with the behavioural research on which they are based. This allows us to show that behavioural policy and the debates accompanying it are based on an oversimplified understanding of what knowledge behavioural science actually provides. Recognising this problem is important as arguments that justify reliance on the behavioural sciences in policy typically presume this simplification. (shrink)

Recent science funding policy scholars and practitioners have advocated for the use of lotteries, or elements of random chance, as supplementations of traditional peer review for evaluating grant applications. One of the primary motivations for lotteries is their purported openness to innovative research. The purpose of this paper is to argue that current proponents of funding science by lottery overestimate the viability of peer review and thus unduly restrict the scope of lotteries in science funding practice. (...) I further show how this analysis suggests a different way of introducing lotteries into science funding policy. (shrink)

A coherent and helpful public policy based on science is difficult to achieve for at least three reasons. First, there are purely practical problems—for example, that scientific experts often disagree on policy-relevant questions and their debates often continue well beyond policy appropriate timelines. Second, there are epistemic problems—for example, that science is hardly the neutral supplier of factual information that traditionally has been supposed. And third, there are social problems: given the commercialization of today’s (...) class='Hi'>science and its enduring limitations, much of scientific research today fails to meet the moral and political standards one would expect it to meet in order to inform public policy. In this paper, we examine such problems in the context of breast cancer screening policy and suggest the role philosophy of science should play in dealing with the situation. (shrink)

While economic and other social science expertise is indispensable for successful public policy-making regarding global climate change, social scientists face trade-offs between the scientific credibility, policy-relevance, and legitimacy of their policy advice. From a philosophical perspective, this book systematically addresses these trade-offs and other crucial challenges facing the integrated economic assessments of the Intergovernmental Panel on Climate Change. Based on John Dewey’s pragmatist philosophy and an analysis of the value-laden nature and reliability of climate change economics, (...) the book develops a refined science-policy model and specific guidelines for these assessments of climate policy options. The core idea is to scientifically explore the various practical implications of alternative climate policy pathways in an interdisciplinary manner, together with diverse stakeholders. This could facilitate an iterative, deliberative public learning process concerning disputed policy issues. This volume makes novel contributions to three strands of the literature: the philosophy of science in policy; the philosophy of economics; and debates about the design of scientific assessments, including the continuous IPCC reform debate. This work is thus interesting for philosophers and other scholars reflecting on the science-policy interface, but also for assessment practitioners, climate policy-makers, and economists. The science-policy approach developed in this volume has already influenced the recent socio-economic IPCC assessment. (shrink)

In this article, we develop critiques of the pipeline model which dominates Western science education policy, using discourse analysis of interviews with two Swedish young women focused on ‘identity work’. We argue that it is important to unpack the ways that the pipeline model fails to engage with intersections of gender, ethnicity, social class and nationality, and their impact on science and with debates about science as elitist and implicated in neoliberalism.

A rapidly growing body of scholarship shows that we can gain new insights into theories and policies by understanding and increasing their systemic structure. This paper will present an overview of this expanding field and discuss how concepts of structure are being applied in a variety of contexts to support collaboration, decision making, learning, prediction, and results. Next, it will delve into the underlying structures of logic that may be found within those theories and policies. Here, we will go beyond (...) Toulmin’s logics of claim and proof that have not proven useful for advancing the social sciences and focus on five structures of “causal logic.” The results suggest a useful and more comprehensive approach to developing deeper understanding of our conceptual systems such as theory and policy.

The UK has been ‘following the science’ in response to the COVID-19 pandemic in line with the national framework for the use of scientific advice in assessment of risk. We argue that the way in which it does so is unsatisfactory in two important respects. Firstly, pandemic policy making is not based on a comprehensive assessment of policy impacts. And secondly, the focus on reasonable worst-case scenarios as a way of managing uncertainty results in a loss of (...) decision-relevant information and does not provide a coherent basis for policy making.

The traditional vision of the role science should play in policy making is of a two stage process of scientists first finding out the facts, and then policy makers making a decision about what to do about them. We argue that this two stage process is a fiction and that a distinction must be drawn between pure science and science in the service of public policy. When science is transferred into the policy (...) realm, its claims to truth get undermined because we must abandon the open-ended nature of scientific inquiry. When we move from the sphere of science to the sphere of policy, we pick an arbitrary point in the open-ended scientific process, and ask our experts to give us the answer. The choice of the endpoint, however, must always be arbitrary and determined by non-scientific factors. Thus, the two stages in the model of first finding the facts, and then making a decision about what to do, cannot be clearly separated. The second stage clearly affects the first. This conclusion will have implications about existing scientific policy institutions. For example, we advocate that the environmental assessment process be radically overhauled, or perhaps even let go. It will be our position that ultimately a better model for the involvement of scientists in public policy debates is that of being participants in particular interest groups, rather than as supposedly unbiased consultants to decision-makers.

Although the application of social science to practical problems of policy and action is still in its early stages, a large body of experience has been accumulated. Social science has been applied, in diverse spheres and with diverse results. The experience is there, but it has not been systematically reviewed and codified. Consequently, no one knows the present status of applied social science or, more importantly, its potentialities.

A collection of essays by Alexander Rosenberg, the distinguished philosopher of science. The essays cover three broad areas related to Darwinian thought and naturalism: the first deals with the solution of philosophical problems such as reductionism, the second with the development of social theories, and the third with the intersection of evolutionary biology with economics, political philosophy, and public policy. Specific papers deal with naturalistic epistemology, the limits of reductionism, the biological justification of ethics, the so-called 'trolley problem' (...) in moral philosophy, the political philosophy of biological endowments, and the Human Genome Project and its implications for policy. Rosenberg's important writings on a variety of issues are here organized into a coherent philosophical framework which promises to be a significant and controversial contribution to scholarship in many areas.

Underdevelopment in Africa continues to be one of the most perplexing issues of this century. Conventional development policies have failed throughout the continent, and lack of scientific and technological capabilities is considered among the primary causes of the prevailing crisis. Attempts to address underdevelopment have been conducted in terms of what is scientifically and technically feasible in industrialized countries instead of what is socioeconomically and culturally desirable in Africa. Undue reliance on foreign scientific and technological expertise hinders local innovation and (...) creativity, which are crucial to self-sustained development. Redefinition of science and technology policies is urgently needed. Africa should not circumvent the use of science and technology in the quest for development, but it is crucial that African policy makers determine in whose interests science and technology will be developed.

The Joint Research Centre (JRC) is the European Commission’s in-house science and knowledge service, employing a substantial staff of scientists devoted to conducting research to provide independent scientific advice for EU policy. Focussed on various research areas aligned with EU priorities, the JRC excels in delivering scientific evidence for policymaking and has published numerous science-for-policy reports and scientific articles. Drawing on a scientific integrity statement, surveys among JRC’s research staff, and thematic discussions with JRC’s research leaders, (...) the JRC has developed a comprehensive Scientific Integrity and Research Ethics (SIRE) framework, including instruments, procedures, and guidelines to ensure high standards and independence in its research. Key components of the SIRE framework include a Scientific Integrity Officer, an Editorial Review Board, a Research Ethics Board, and guidelines for responsible conduct of research. This article provides an overview of the JRC’s SIRE framework and how it was developed, emphasising the importance of maintaining independence, integrity, and ethics in scientific research that supports EU policy. The article also discusses potential gaps in the framework and where additional efforts may be needed, comparing with the recent U.S. National Science and Technology Council report on Protecting the Integrity of Government Science.

While dissent is key to successful science, it is not always beneficial. By requiring scientists to respond to objections, epistemically detrimental dissent (EDD) consumes resources that could be better devoted to furthering scientific discovery. Moreover, bad-faith dissent can create a chilling effect on certain lines of inquiry and make settled controversies seem open to debate. Such dissent results in harm to scientific progress and the public policy that depends on this science. Biddle and Leuschner propose four criteria (...) that draw on inductive risk as a method for separating this EDD from beneficial dissent while de Melo-Martín and Intemann reject this approach for failing to capture paradigmatic instances of EDD. Against de Melo-Martín and Intemann’s objections, I propose the inductive risk account can be saved and strengthened through the following modifications: (1) removing the requirement that the four conditions of EDD be jointly satisfied, (2) requiring that each criterion be measured as a matter of degree rather than as a binary, and (3) requiring that the four criteria are measured holistically. These modifications not only mitigate the criticisms but produce five benefits over Biddle and Leuschner’s account, including: (1) capturing paradigmatic instances of EDD, (2) reflecting the degree to which an instance of EDD is problematic, (3) capturing the interactions between criteria, (4) avoiding legitimizing inappropriate dissent, and (5) reflecting changes to the epistemic standing of dissent. As such, I argue that the modified IndRA provides a powerful tool for identifying EDD and strengthening science. (shrink)

How does science enter policy making, and for what purpose? Surely consulting scientific facts in making policy is done with a view to making policy decisions more reliable, and ultimately more objective. In this paper I address the way/s by which science contributes to achieving objectivity in policy making and social debate, and argue that objectivity is not exhausted by what scientific evidence contributes to either. In policy making and social debates, scientific evidence (...) is taken into account alongside other relevant factors. Such complex contexts of practical interaction constitute a challenge both for the objectivity of scientific evidence, and for the objectivity of the role of the scientist in the policy-making process I analyse a case study - the ongoing debate over the spread of bovine TB in the UK - that displays some of the worries and several of the aspects we ought to keep in mind when we bring scientific objectivity to bear on social debate and policy making. I argue in favour of a picture where scientific objectivity enters a productive and effective dialogue with practical objectivity. (shrink)

Biodiversity studies comprise the systematic examination of the full array of different kinds of organisms together with the technology by which the diversity can be maintained and used for the benefit of humanity.

We discuss the relationship between expertise, expert authority, and trust in the case of vaccine research and policy, with a particular focus on COVID-19 vaccines. We argue that expert authority is not merely an epistemic notion, but entails being trusted by the relevant public and is valuable if it is accompanied by expert trustworthiness. Trustworthiness requires, among other things, being transparent, acknowledging uncertainty and expert disagreement (e.g., around vaccines’ effectiveness and safety), being willing to revise views in response to (...) new evidence, and being clear about the values that underpin expert recommendations. We explore how failure to acknowledge expert disagreement and uncertainty can undermine trust in vaccination and public health experts, using expert recommendations around COVID-19 vaccines as a case study.

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.

This paper examines potential responses to emerging ‘climate refugee’ justice issues. ‘Climate refugee’ describes migrants forced to flee their homeland due to losses and damages brought about by events linked to global climate change. These include losses and damages due to extreme weather events, severe droughts and floods, sea-level rise, and an array of pollutant contamination issues. A paradigm case if climate refugeedom is seen in the influx of Peruvian immigrants into various North American cities; seeking asylum after losing access (...) to water and agricultural resources after heavy metals were released through rapid glacial melting and contaminated these necessities in recent years. -/- The main discussion begins with a sketch of the scientific picture of the causal genesis of the apparently worsening “climate refugee crisis” and a concise discussion of new climate science research methods, Probabilistic Event Attribution studies (PEAs), that many agree can be used to determine the liability of certain countries for particular extreme events due to climate change (§1). Against that background, and after providing clarifications regarding the distinction between ‘climate refugee’ and ‘environmental refugee’ (§2), I then discuss key ethical and political issues that are unique to climate refugee cases (§3). Subsequently, I critically assess options for helping climate refugees through existing institutions (§4). I endorse pursuing responses to the most pressing climate refugee problems through the provisions for addressing climate change “losses and damages” in the 2016 UN Framework Convention on Climate Change, “Paris Agreement”; which outlines “risk sharing” protocol that I contend can be used to help climate refugees who are not currently subject to existing UN policies designed to help other types of refugees (e.g. those fleeing from persecution or war). I conclude by outlining a number of ways that PEAs may aid in effectively implementing those losses and damages provisions. (shrink)

This paper examines the promise of science and its role in shaping research policy. The promise of science is characterized by expectations of science, which are embedded in promissory discourses that envision futures made possible through advances in promising science. Through a single case study of the origins of Genome Canada, the research was guided by the question: How did expectations of genomics shape the creation of Genome Canada? A conceptualization of discursive power and expectations (...) of genomics storylines provide the theoretical and analytical basis for an in-depth examination of the ideational effects and material impacts on research policy decisions over three years that culminated in the creation of Genome Canada. Expectations of genomics storylines functioned in a complex interplay of discursive practices and dynamics among diverse policy actors within a genomics discourse-coalition to produce a range of ideational and material impacts. The expectations of genomics storylines produced powerful genomics subject-positions from which policy actors perceived their interests, identities and preferences and gained agency, which led to various material impacts, such as mobilizing support and funding, coordinating activities and transforming Canada’s research policy framework. With the increasing importance of research policy to a range of broader policy priorities underpinned by expectations that science will resolve societal challenges and contribute to socio-economic benefits, this paper sheds light on how complex research policy decisions are made; it further contributes to understanding the role of promissory discourses in shaping those decisions.

Recent years have witnessed a revival of scientific, political and philosophical discourse concerning the notion of ecological limits. This article provides a conceptual overview of descriptive ecological limit claims—i.e. claims that there are real, biophysical limits—and reviews work in political and social philosophy in which such claims form the basis of proposals for normative limits. The latter are classified in terms of three broad types of normative theorising: distributive justice, institutional/legal reform, and the good life. Within these three categories, the (...) article reviews normative proposals for limits on both aggregate‐level and individual‐level ecological exploitation. It also considers the relevance of political and ideological facts to the normative analysis of ecological limits, raising methodological questions about how normative theorists should respond to a world facing escalating ecological challenges.
