White supremacy is the unnamed political system that has made the modern world what it is today. You will not find this term in introductory, or even advanced, texts in political theory. A standard undergraduate philosophy course will start off with plato and Aristotle, perhaps say something about Augustine, Aquinas, and Machiavelli, move on to Hobbes, Locke, Mill, and Marx, and then wind up with Rawls and Nozick. It will introduce you to notions of aristocracy, democracy, absolutism, liberalism, representative government, (...) socialism, welfare capitalism, andlibertarianism. But though it covers more than two thousand years of Western political thought and runs the ostensible gamut of political systems, there will be no mention of the basic political system that has shaped the world for the past several hundred years. And this omission is not accidental. Rather, it reflects the fact that standard textbooks and courses have for the most part been written and designed by whites, who take their racial privilege so much for granted that they do not even see it as political, as a form of domination. Ironically, the most important political system of recent global history-the system of domination by which white people have historically ruled over and, in certain important ways, continue to rule over nonwhite people-is not seen as a political system at all. It is just taken for granted; it is the background against which other systems, which we are to see as political are highlighted. This book is an attempt to redirect your vision, to make you see what, in a sense, has been there all along. (shrink)

This is an important book precisely because there is none other quite like it.

Fake research produces results that are invalid from the start. I take such research to be characterised by three jointly sufficient features. It is severely methodologically defective, and the relevant defects support certain nonepistemic (social, political, economic) interests and objectives, while the relevant objectives typically concern the interference with attempts at political regulation. I deal with two kinds of claimed fake research. One is agnotological ploys in which scientific dissent is created by interested parties from industry or politics in order (...) to support their own partisan goals. Another one is the populist antiscience movement that suspects fake research in the scientific mainstream. I suggest three remedies to reduce or eliminate the impact of fake research: disclosing fallacies, improving the understanding of scientific methods, and distinguishing more clearly between science and politics in political decision-making.

In Science as Social Knowledge in 1990 and The Fate of Knowledge in 2002, Helen Longino develops an epistemological theory known as Critical Contextual Empiricism (CCE). Knowledge production, she argues, is an active, value-laden practice, evidence is context dependent and relies on background assumptions, and science is a social inquiry that, under certain conditions, produces social knowledge with contextual objectivity. While Longino’s work has been generally well-received, there have been a number of criticisms of CCE raised in the philosophical literature (...) in recent years. In this paper I outline the key elements of Longino’s theory and propose modifications to the four norms offered by the account. The version of CCE I defend, which draws on lessons learned by medical researchers in recent years, gives principles of epistemic diversity a central role and also provides greater specification of three of the four norms. Further, it offers additional resources for defending CCE against Alvin Goldman’s suggestion that there is a need for a “healthy dogmatism” in science, as well as a concern about “manufactured uncertainty” arising out of recent work by David Michaels. Finally, the modified version proposed here is also well positioned to respond (negatively) to a suggestion from Kristen Intemann that CCE needs to be adapted to incorporate a central insight from feminist standpoint theory. In light of the variety of social pressures influencing contemporary scientific research, and the role of science in shaping public policy, I argue that a rigorous social epistemology such as CCE is indispensable for understanding and assessing contemporary scientific practice.

The aim of this paper is to address the neglected but important problem of differentiating between epistemically beneficial and epistemically detrimental dissent. By “dissent,” we refer to the act of objecting to a particular conclusion, especially one that is widely held. While dissent in science can clearly be beneficial, there might be some instances of dissent that not only fail to contribute to scientific progress, but actually impede it. Potential examples of this include the tobacco industry’s funding of studies that (...) questioned the link between smoking and lung cancer, and the attempt by the petroleum industry and other groups to cast doubt upon the conclusion that human consumption of fossil fuels contributes to global climate change. The problem of distinguishing between good and bad dissent is important because of the growing tendency of some stakeholders to attempt to delay political action by ’manufacturing doubt’. Our discussion in this paper focuses on climate science. This field, in our view, is rife with instances of bad dissent. On the basis of our discussion of climate science, we articulate a set of sufficient conditions for epistemically problematic dissent in general, which we call “the inductive risk account of epistemically detrimental dissent.”.

An introduction to the new area of ignorance studies that examines how science produces ignorance—both actively and passively, intentionally and unintentionally. We may think of science as our foremost producer of knowledge, but for the past decade, science has also been studied as an important source of ignorance. The historian of science Robert Proctor has coined the term agnotology to refer to the study of ignorance, and much of the ignorance studied in this new area is produced by science. Whether (...) an active or passive construct, intended or unintended, this ignorance is, in Proctor's words, “made, maintained, and manipulated” by science. This volume examines forms of scientific ignorance and their consequences. A dialogue between Proctor and Peter Galison offers historical context, presenting the concerns and motivations of pioneers in the field. Essays by leading historians and philosophers of science examine the active construction of ignorance by biased design and interpretation of experiments and empirical studies, as seen in the “false advertising” by climate change deniers; the “virtuous” construction of ignorance—for example, by curtailing research on race- and gender-related cognitive differences; and ignorance as the unintended by-product of choices made in the research process, when rules, incentives, and methods encourage an emphasis on the beneficial and commercial effects of industrial chemicals, and when certain concepts and even certain groups' interests are inaccessible in a given conceptual framework.

Worries about scientific objectivity seem never-ending. Social critics and philosophers of science have argued that invocations of objectivity are often little more than attempts to boost the status of a claim, while calls for value neutrality may be used to suppress otherwise valid dissenting positions. Objectivity is used sometimes to advance democratic agendas, at other times to block them; sometimes for increasing the growth of knowledge, at others to resist it. Sandra Harding is not ready to throw out objectivity quite (...) yet. For all of its problems, she contends that objectivity is too powerful a concept simply to abandon. In Objectivity and Diversity, Harding calls for a science that is both more epistemically adequate and socially just, a science that would ask: How are the lives of the most economically and politically vulnerable groups affected by a particular piece of research? Do they have a say in whether and how the research is done? Should empirically reliable systems of indigenous knowledge count as "real science"? Ultimately, Harding argues for a shift from the ideal of a neutral, disinterested science to one that prizes fairness and responsibility. (shrink)

The lack of public support for climate change policies and refusals to vaccinate children are just two alarming illustrations of the impacts of dissent about scientific claims. Dissent can lead to confusion, false beliefs, and widespread public doubt about highly justified scientific evidence. Even more dangerously, it has begun to corrode the very authority of scientific consensus and knowledge. Deployed aggressively and to political ends, some dissent can intimidate scientists, stymie research, and lead both the public and policymakers to oppose (...) important public policies firmly rooted in science. -/- To criticize dissent is, however, a fraught exercise. Skepticism and fearless debate are key to the scientific process, making it both vital and incredibly difficult to characterize and identify dissent that is problematic in its approach and consequences. Indeed, as de Melo-Martín and Intemann show, the criteria commonly proposed as means of identifying inappropriate dissent are flawed and the strategies generally recommended to tackle such dissent are not only ineffective but could even make the situation worse. -/- The Fight Against Doubt proposes that progress on this front can best be achieved by enhancing the trustworthiness of the scientific community and by being more realistic about the limits of science when it comes to policymaking. It shows that a richer understanding of the context in which science operates is needed to disarm problematic dissent and those who deploy it. This, the authors argue, is the best way forward, rather than diagnosing the many instances of wrong-headed dissent. (shrink)

"Why should we care about having true beliefs? And why do demonstrably false beliefs persist and spread despite consequences for the people who hold them? Philosophers of science Cailin O’Connor and James Weatherall argue that social factors, rather than individual psychology, are what’s essential to understanding the spread and persistence of false belief. It might seem that there’s an obvious reason that true beliefs matter: false beliefs will hurt you. But if that’s right, then why is it irrelevant to many (...) people whether they believe true things or not? In an age riven by "fake news," "alternative facts," and disputes over the validity of everything from climate change to the size of inauguration crowds, the authors argue that social factors, not individual psychology, are what’s essential to understanding the persistence of false belief and that we must know how those social forces work in order to fight misinformation effectively."–Publisher’s description.

Helen Longino seeks to break the current deadlock in the ongoing wars between philosophers of science and sociologists of science--academic battles founded on disagreement about the role of social forces in constructing scientific knowledge. While many philosophers of science downplay social forces, claiming that scientific knowledge is best considered as a product of cognitive processes, sociologists tend to argue that numerous noncognitive factors influence what scientists learn, how they package it, and how readily it is accepted. Underlying this disagreement, however, (...) is a common assumption that social forces are a source of bias and irrationality. Longino challenges this assumption, arguing that social interaction actually assists us in securing firm, rationally based knowledge. This important insight allows her to develop a durable and novel account of scientific knowledge that integrates the social and cognitive. Longino begins with a detailed discussion of a wide range of contemporary thinkers who write on scientific knowledge, clarifying the philosophical points at issue. She then critically analyzes the dichotomous understanding of the rational and the social that characterizes both sides of the science studies stalemate and the social account that she sees as necessary for an epistemology of science that includes the full spectrum of cognitive processes. Throughout, her account is responsive both to the normative uses of the term knowledge and to the social conditions in which scientific knowledge is produced. Building on ideas first advanced in her influential book Science as Social Knowledge, Longino brings her account into dialogue with current work in social epistemology and science studies and shows how her critical social approach can help solve a variety of stubborn problems. While the book focuses on epistemological concerns related to the sociality of inquiry, Longino also takes up its implications for scientific pluralism. The social approach, she concludes, best allows us to retain a meaningful concept of knowledge in the face of theoretical plurality and uncertainty. (shrink)

This article utilizes the ongoing debates over the role of certain agricultural insecticides in causing Colony Collapse Disorder —the phenomenon of accelerated bee die-offs in the United States and elsewhere—as an opportunity to contribute to the emerging literature on the social production of ignorance. In our effort to understand the social contexts that shape knowledge/nonknowledge production in this case, we develop the concept of epistemic form. Epistemic form is the suite of concepts, methods, measures, and interpretations that shapes the ways (...) in which actors produce knowledge and ignorance in their professional/intellectual fields of practice. In the CCD controversy, we examine how the privileging of certain epistemic forms intersects with the social dynamics of academic, regulatory, and corporate organizations to lead to the institutionalization of three interrelated and overlapping types of ignorance. We consider the effects of these types of ignorance on US regulatory policy and on the lives of different stakeholders. (shrink)

The article explores the concept of infodemics during the COVID-19 pandemic, focusing on the propagation of false or inaccurate information proliferating worldwide throughout the SARS-CoV-2 health crisis. We provide an overview of disinformation, misinformation and malinformation and discuss the notion of “fake news”, and highlight the threats these phenomena bear for health policies and national and international security. We discuss the mis-/disinformation as a significant challenge to the public health, intelligence, and policymaking communities and highlight the necessity to design measures (...) enabling the prevention, interdiction, and mitigation of such threats. We then present an overview of selected opportunities for applying technology to study and combat disinformation, outlining several approaches currently being used to understand, describe, and model the phenomena of misinformation and disinformation. We focus specifically on complex networks, machine learning, data- and text-mining methods in misinformation detection, sentiment analysis, and agent-based models of misinformation spreading and the detection of misinformation sources in the network. We conclude with the set of recommendations supporting the World Health Organization’s initiative on infodemiology. We support the implementation of integrated preventive procedures and internationalization of infodemic management. We also endorse the application of the cross-disciplinary methodology of Crime Science discipline, supplemented by Big Data analysis and related information technologies to prevent, disrupt, and detect mis- and disinformation efficiently.

Gender bias is a recalcitrant problem in academia and society. However, dissent has been created on this issue. We focus on dissenting studies by Stephen J. Ceci and Wendy M. Williams, arguing that they reach conclusions that are unwarranted on the basis of the available evidence and that they ignore fundamental objections to their methodological decisions. Drawing on discussions from other contexts, particularly on manufactured dissent concerning anthropogenic climate change, we conclude that dissent on gender bias substantially contributes to the (...) exacerbation of biases in society and an increasing number of attacks on researchers, making it both epistemically and socially problematic.

There is overwhelming evidence that the opioid crisis—which has cost hundreds of thousands of lives and trillions of dollars (and counting)—has been created or exacerbated by webs of influence woven by several pharmaceutical companies. These webs involve health professionals, patient advocacy groups, medical professional societies, research universities, teaching hospitals, public health agencies, policymakers, and legislators. Opioid companies built these webs as part of corporate strategies of influence that were designed to expand the opioid market from cancer patients to larger groups (...) of patients with acute or chronic pain, to increase dosage as well as opioid use, to downplay the risks of addiction and abuse, and to characterize physicians’ concerns about the addiction and abuse risks as “opiophobia.” In the face of these pervasive strategies, conflict of interest policies have proven insufficient for addressing corporate influence in medical practice, medical research, and public health policy. Governments, the academy, and civil society need to develop counterstrategies to insulate themselves from corporate influence and to preserve their integrity and public trust. These strategies require a paradigm shift—from partnerships with the private sector, which are ordinarily vehicles for corporate influence, to a norm of separation. (shrink)

Science strives for coherence. For example, the findings from climate science form a highly coherent body of knowledge that is supported by many independent lines of evidence: greenhouse gas emissions from human economic activities are causing the global climate to warm and unless GHG emissions are drastically reduced in the near future, the risks from climate change will continue to grow and major adverse consequences will become unavoidable. People who oppose this scientific body of knowledge because the implications of cutting (...) GHG emissions—such as regulation or increased taxation—threaten their worldview or livelihood cannot provide an alternative view that is coherent by the standards of conventional scientific thinking. Instead, we suggest that people who reject the fact that the Earth’s climate is changing due to greenhouse gas emissions oppose whatever inconvenient finding they are confronting in piece-meal fashion, rather than systematically, and without considering the implications of this rejection to the rest of the relevant scientific theory and findings. Hence, claims that the globe “is cooling” can coexist with claims that the “observed warming is natural” and that “the human influence does not matter because warming is good for us.” Coherence between these mutually contradictory opinions can only be achieved at a highly abstract level, namely that “something must be wrong” with the scientific evidence in order to justify a political position against climate change mitigation. This high-level coherence accompanied by contradictory subordinate propositions is a known attribute of conspiracist ideation, and conspiracism may be implicated when people reject well-established scientific propositions.

Philip Kitcher and I agree that cognitive values are not only intelligible but play an important role in scientific inquiry. We also agree that the importance of authority is critical to understanding the social dimension of such inquiry. We disagree rather deeply concerning what the roles of cognitive goals and the social dimension are.

As Justin Biddle and I have argued, climate skepticism can be epistemically problematic when it displays a systematic intolerance of producer risks at the expense of public risks : 261–278, 2015). In this paper, I will provide currently available empirical evidence that supports our account, and I discuss the normative consequences of climate skepticism by drawing upon Philip Kitcher’s “Millian argument against the freedom of inquiry.” Finally, I argue that even though concerns regarding inappropriate disqualification of dissent are reasonable, a (...) form of “targeting” dissent—namely revealing manufactured dissent—is required in order to identify epistemically detrimental dissent and, thus, to protect scientific and public discourse.

For centuries scientists have claimed that women are intellectually inferior to men and blacks are inferior to whites. Although these claims have been contested and corrected for centuries, they still continue to be made. Meanwhile, scientists have documented the harm done to women and blacks by the publication of such claims. Can anything be done to improve this situation? Freedom of research is universally recognized to be of first-rate importance. Yet, constraints on that freedom are also universally recognized. I consider (...) three of these constraints and argue for tighter restrictions on race- and gender-related cognitive differences research on their basis. (shrink)

During the last three decades, reflections on the growth of scientific knowledge have inspired historians, sociologists, and some philosophers to contend that scientific objectivity is a myth. In this book, Kitcher attempts to resurrect the notions of objectivity and progress in science by identifying both the limitations of idealized treatments of growth of knowledge and the overreactions to philosophical idealizations. Recognizing that science is done not by logically omniscient subjects working in isolation, but by people with a variety of personal (...) and social interests, who cooperate and compete with one another, he argues that, nonetheless, we may conceive the growth of science as a process in which both our vision of nature and our ways of learning more about nature improve. Offering a detailed picture of the advancement of science, he sets a new agenda for the philosophy of science and for other "science studies" disciplines. (shrink)

Striving to boldly redirect the philosophy of science, this book by renowned philosopher Philip Kitcher examines the heated debate surrounding the role of science in shaping our lives. Kitcher explores the sharp divide between those who believe that the pursuit of scientific knowledge is always valuable and necessary--the purists--and those who believe that it invariably serves the interests of people in positions of power. In a daring turn, he rejects both perspectives, working out a more realistic image of the sciences--one (...) that allows for the possibility of scientific truth, but nonetheless permits social consensus to determine which avenues to investigate. He then proposes a democratic and deliberative framework for responsible scientists to follow. Controversial, powerful, yet engaging, this volume will appeal to a wide range of readers. Kitcher's nuanced analysis and authorititative conclusion will interest countless scientists as well as all readers of science--scholars and laypersons alike. (shrink)

‘‘Undone science’’ refers to areas of research that are left unfunded, incomplete, or generally ignored but that social movements or civil society organizations often identify as worthy of more research. This study mobilizes four recent studies to further elaborate the concept of undone science as it relates to the political construction of research agendas. Using these cases, we develop the argument that undone science is part of a broader politics of knowledge, wherein multiple and competing groups struggle over the construction (...) and implementation of alternative research agendas. Overall, the study demonstrates the analytic potential of the concept of undone science to deepen understanding of the systematic nonproduction of knowledge in the institutional matrix of state, industry, and social movements that is characteristic of recent calls for a ‘‘new political sociology of science.’’.

Since 2016, there has been an explosion of academic work and journalism that fixes its subject matter using the terms ‘fake news’ and ‘post-truth’. In this paper, I argue that this terminology is not up to scratch, and that academics and journalists ought to completely stop using the terms ‘fake news’ and ‘post-truth’. I set out three arguments for abandonment. First, that ‘fake news’ and ‘post-truth’ do not have stable public meanings, entailing that they are either nonsense, context-sensitive, or contested. (...) Secondly, that these terms are unnecessary, because we already have a rich vocabulary for thinking about epistemic dysfunction. Thirdly, I observe that ‘fake news’ and ‘post-truth’ have propagandistic uses, meaning that using them legitimates anti-democratic propaganda, and runs the risk of smuggling bad ideology into conversations.

The aim of the paper is to clarify the concept of scientific ignorance: what is it, what are its sources, and when is it epistemically detrimental for science. I present a taxonomy of scientific ignorance, distinguishing between intrinsic and extrinsic sources. I argue that the latter can create a detrimental epistemic gap, which have significant epistemic and social consequences. I provide three examples from medical research to illustrate this point. To conclude, I claim that while some types of scientific ignorance (...) are inevitable and even desirable, other types of scientific ignorance are epistemically and ethically flawed and should be prevented.

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.

For decades, cigarette companies helped to promote the impression that there was no scientific consensus concerning the safety of their product. The appearance of controversy, however, was misleading, designed to confuse the public and to protect industry interests. Created scientific controversies emerge when expert communities are in broad agreement but the public perception is one of profound scientific uncertainty and doubt. In the first book-length analysis of the concept of a created scientific controversy, David Harker explores issues including climate change, (...) Creation science, the anti-vaccine movement and genetically modified crops. Drawing on work in cognitive psychology, social epistemology, critical thinking and philosophy of science, he shows readers how to better understand, evaluate, and respond to the appearance of scientific controversy. His book will be a valuable resource for students of philosophy of science, environmental and health sciences, and social and natural sciences. (shrink)

"Doubt is our product," a cigarette executive once observed, "since it is the best means of competing with the 'body of fact' that exists in the minds of the general public. It is also the means of establishing a controversy." In this eye-opening expose, David Michaels reveals how the tobacco industry's duplicitous tactics spawned a multimillion dollar industry that is dismantling public health safeguards. Product defense consultants, he argues, have increasingly skewed the scientific literature, manufactured and magnified scientific uncertainty, and (...) influenced policy decisions to the advantage of polluters and the manufacturers of dangerous products. To keep the public confused about the hazards posed by global warming, second-hand smoke, asbestos, lead, plastics, and many other toxic materials, industry executives have hired unscrupulous scientists and lobbyists to dispute scientific evidence about health risks. In doing so, they have not only delayed action on specific hazards, but they have constructed barriers to make it harder for lawmakers, government agencies, and courts to respond to future threats. The Orwellian strategy of dismissing research conducted by the scientific community as "junk science" and elevating science conducted by product defense specialists to "sound science" status also creates confusion about the very nature of scientific inquiry and undermines the public's confidence in science's ability to address public health and environmental concerns Such reckless practices have long existed, but Michaels argues that the Bush administration deepened the dysfunction by virtually handing over regulatory agencies to the very corporate powers whose products and behavior they are charged with overseeing. In Doubt Is Their Product Michaels proves, beyond a doubt, that our regulatory system has been broken. He offers concrete, workable suggestions for how it can be restored by taking the politics out of science and ensuring that concern for public safety, rather than private profits, guides our regulatory policy.

By exploring diverse and sometimes positive roles for ignorance, A Defense of Ignorance offers a revisionary approach to epistemology that challenges core assumptions about epistemic values. Townley contributes innovative ways of thinking about the practicalities and politics of knowledge and argues for an expanded domain of responsible epistemic conduct. All social scientists, especially those interested in knowledge and in feminist scholarship, stand to benefit from Townley's arguments.

The U.S. scientific community has long led the world in research on such areas as public health, environmental science, and issues affecting quality of life. These scientists have produced landmark studies on the dangers of DDT, tobacco smoke, acid rain, and global warming.

Leading scholars explore how different forms of ignorance are produced and sustained, and the role they play in knowledge practices.

Research on bias in peer review examines scholarly communication and funding processes to assess the epistemic and social legitimacy of the mechanisms by which knowledge communities vet and self-regulate their work. Despite vocal concerns, a closer look at the empirical and methodological limitations of research on bias raises questions about the existence and extent of many hypothesized forms of bias. In addition, the notion of bias is predicated on an implicit ideal that, once articulated, raises questions about the normative implications (...) of research on bias in peer review. This review provides a brief description of the function, history, and scope of peer review; articulates and critiques the conception of bias unifying research on bias in peer review; characterizes and examines the empirical, methodological, and normative claims of bias in peer review research; and assesses possible alternatives to the status quo. We close by identifying ways to expand conceptions and studies of bias to countenance the complexity of social interactions among actors involved directly and indirectly in peer review. (shrink)

Claims that science should be more democratic than it is frequently arouse opposition. In this essay, I distinguish my own views about the democratization of science from the more ambitious theses defended by Paul Feyerabend. I argue that it is unlikely that the complexity of some scientific debates will allow for resolution according to the methodological principles of any formal confirmation theory, suggesting instead that major revolutions rest on conflicts of values. Yet these conflicts should not be dismissed as irresoluble.
