Investment in agricultural extension, as well as its design and practice, are usually based on the assumption that agricultural science generates technology (“applied science“), which extension experts transfer to “users“. This model negates local knowledge and creativity, ignores farmers' self-confidence and social energy as important sources of change, and, in its most linear expression, does not pay attention to information from and about farmers as a condition for anticipating utilization.In practice, farmers rely on knowledge developed by farmers, reinvent ideas brought (...) from outside and actively integrate them into complex farming decisions. Effective extension seems based on checks and balances that match intervention power with farmers' countervailing power, and mobilize farmers' creativity and participation in technology development and exchange.Alternative models for informing extension investment, design, and practice stress adult learning and its facilitation. The farmer is seen as an expert and farm development as driven by farmers' energy and communication. The article is a case study of a rare large scale attempt to use such an alternative model. It suggests that a shift to knowledgeintensive sustainable practices requires a learning process based on participation and empowerment. (shrink)

The role of scientists as experts is crucial to public policymaking. However, the expert role is contested and unsettled in both public and scholarly discourse. In this paper, I provide a systematic account of the role of scientists as experts in policymaking by examining whether there are any normatively relevant differences between this role and the role of scientists as researchers. Two different interpretations can be given of how the two roles relate to each (...) other. The separability view states that there is a normatively relevant difference between the two roles, whereas the inseparability view denies that there is such a difference. Based on a systematic analysis of the central aspects of the role of scientists as experts – that is, its aim, context, mode of output, and standards, I propose a moderate version of the separability view. Whereas the aim of scientific research is typically to produce new knowledge through the use of scientific method for evaluation and dissemination in internal settings, the aim of the expert is to provide policymakers and the public with relevant and applicable knowledge that can premise political reasoning and deliberation.

Is subjective expert judgment a source of evidence in economics? In this paper, I will argue that it is, on a par with other sources like modeling, statistics, experimental, etc. I will also argue that it is not derivative, that is, reducible to the previous ones. But what is exactly the role of experts in economics? The contribution to the current methodological debate that I propose not only takes the role of expertise in economics as indispensable, but (...) also suggests a need for a methodology associated with that role. I defend an indispensability argument, and indirectly David Colander's plea for refocusing the methodological debate on the lost art of economics. Finally, I indicate where to look for guidelines in formulating a methodology of economic expertise. (shrink)

The goal of this paper is to describe the mechanism of the public perception of risk of artificial intelligence. For that we apply the social amplification of risk framework to the public perception of artificial intelligence using data collected from Twitter from 2007 to 2018. We analyzed when and how there appeared a significant representation of the association between risk and artificial intelligence in the public awareness of artificial intelligence. A significant finding is that the image of the risk of (...) AI is mostly associated with existential risks that became popular after the fourth quarter of 2014. The source of that was the public positioning of experts who happen to be the real movers of the risk perception of AI so far instead of actual disasters. We analyze here how this kind of risk was amplified, its secondary effects, what are the varieties of risk unrelated to existential risk, and what is the dynamics of the experts in addressing their concerns to the audience of lay people.

The consensus among legal philosophers is probably that rule-based legal expert systems leave much to be desired as aids in legal decision-making. Why? What can we do about it? A bureaucrat administering some set of complex rules will ascertain the facts and apply the rules to them in order to discover their consequences for the case in hand. This process of deductive reasoning is characteristically bureaucratic.

‘‘Anecdotal evidence’’ has become a central point of contention in two recent controversies over science and technology in referring to our cases as controversies over science and technology.) in the United Kingdom and a contact point between individuals, expert institutions, and policy decisions. We argue that the term is central to the management of the boundary between experts and nonexperts, with consequences for ideas of public engagement and participation. This article reports on two separate pieces of qualitative social research (...) into recent UK public risk controversies with the aim of unfolding the processes by which anecdotal evidence comes to be defined. We do not define anecdotal evidence as an epistemic category that exists prior to the public controversies themselves; rather, we aim to show how the term is constructed and contested by expert and nonexpert actors. We find that anecdotal evidence comes to be accepted by the main actors as an epistemic category, yet that it is multidimensional, open to interpretation as subjective reports, as an indicator of expert ignorance, as a source of novel hypotheses and as a set of political claims for recognition and inclusion. We conclude that the flexibility of anecdotal evidence at the boundary between science and its publics can offer opportunities for participation and engagement, as well as exclusion and alienation.

L’objet du présent article est le suivant : comment développer une justification publique en matière de justice qui respecte à la fois le pluralisme entre des citoyens libres et égaux, la qualité épistémique des décisions et la responsabilité épistémique? Pour aborder ce problème, j’envisage le modèle de justification publique proposé par John Rawls, en particulier sa conception de la légitimité et de la justification des décisions publiques présentes dans sa théorie de la raison publique. J’insiste sur les éléments épistémiques de (...) la doctrine de Rawls concernant la justification publique, en particulier le rapport à la science dans le cadre de la raison publique. Je propose toutefois d’amender la description rawlsienne des raisons scientifiques publiques afin d’inclure un ensemble de raisons plus ancrées dans les besoins du monde réel, à savoir de considérer la légitimité d’un ensemble de conclusions scientifiques raisonnables, en tant que raisons justificatives publiques valides, sans se limiter à des conclusions hors de toute controverse. J’indique le problème que constitue l’attribution de légitimité au pluralisme raisonnable des raisons scientifiques pour une détermination probante des politiques. Ma solution consiste à considérer comme légitimes — parce que raisonnables — des décisions sélectionnées selon une procédure démocratique équitable. (shrink)

Goldman's notions of expert and testimony in epistemological contexts are extended to normative issues. The result is a sketch of a conceptual framework: several types of experts and roles they can serve in informing not specially qualified recipients are distinguished; differences between experts in epistemological and moral contexts are highlighted. This framework then is the point of reference for claims about experts, expertise and moral testimony in Birnbacher's and Jones & Schroeter's contributions to this volume. First, Birnbacher's worries about (...) the legitimacy of moral philosophers sitting as experts on panels, etc. are allayed in one respect and aggravated in another: there are roles and qualifications open to informants about normative issues, but it is doubtful whether moral philosophers per se are up to each of them. Secondly, Jones & Schroeter's objection to Hills's claim that moral testimony cannot orient its recipient properly towards right-making reasons for acting is faulty. (shrink)

In every poll asking the public to rank professions by prestige, scientists excel. They command great respect and earn high marks for trustworthiness. They consistently compare well to judges and rank much higher than lawmakers. Scientists also outrank polltakers, which I suppose reveals the public’s view that polls are not scientific. In democratic societies, however, despite general esteem for scientists, political authorities and members of the public often ignore or override what scientists have to say about science. In what follows, (...) I want to consider three major roles that experts play in democratic societies, and to take a brief look at how experts handle some cases when their authority is challenged.

It is not clear whether breast cancer screening is a public health intervention or an individual clinical service. The question is important because the concepts best suited for ethical reasoning in public health might be different to the concepts commonly employed in biomedical ethics. We consider it likely that breast screening has elements of a public health intervention and used an empirical ethics approach to explore this further. If breast screening has public health characteristics, it is probable that policy and (...) practice experts will employ socially embedded concepts when reasoning about it. We gathered data on whether and how these concepts existed in the discussion and reasoning of Australian breast screening experts. We found that experts employed these concepts when talking about the purpose and practices of breast screening, and the behaviour of breast screening professionals and consumers. Experts gave varied judgements about breast screening based on reasoning with these concepts, considering it to be more or less successful in contributing to the public interest and in incorporating socially embedded concepts into its operational agenda. Our findings are compatible with breast screening having public health characteristics. We advocate for the incorporation of socially embedded concepts in breast screening policy and practice.

Dreyfus and Dreyfus’ influential phenomenological analysis of skill acquisition proposes that expert performance is guided by non-cognitive responses which are fast, effortless and apparently intuitive in nature. Although this model has been criticised for over-emphasising the role that intuition plays in facilitating skilled performance, it does recognise that on occasions a form of ‘detached deliberative rationality’ may be used by experts to improve their performance. However, Dreyfus and Dreyfus see no role for calculative problem solving or deliberation (...) when performance is going well. In the current paper, we draw on empirical evidence, insights from athletes, and phenomenological description to argue that ‘continuous improvement’ among experts is mediated by cognitive control in three distinct sporting situations. We conclude by arguing that Sutton et al. Journal of the British Society for Phenomenology, 42, 78–103 ‘applying intelligence to the reflexes’ approach may help to elucidate the process by which expert performers achieve continuous improvement through analytical/mindful behaviour during training and competition.

Epistemic democrats are rightly concerned with the quality of outcomes and judge democratic procedures in terms of their ability to ‘track the truth’. However, their impetus to assess ‘rule by experts’ and ‘rule by the people’ as mutually exclusive has led to a meagre treatment of the role of expert knowledge in democracy. Expertise is often presented as a threat to democracy but is also crucial for enlightened political processes. Contemporary political philosophy has so far paid little attention (...) to our reliance on experts and has not sufficiently addressed the question of how expertise can be used to improve the epistemic quality of democratic decision making. We believe this lack of interest is spurred by a too hasty acceptance of arguments dismissive of the political role of experts. The article examines a series of often-cited epistemic objections and concludes that several of them are overstated or misconceived, yet they all reflect real difficulties that need to be addressed. On this background, we tentatively outline a set of mechanisms that can contribute to alleviating the irreducible problem of epistemic asymmetries and ensuring that experts really are experts and use their expertise in the right way.

_GPs serve in a double role of treatment provider and expert in certain social insurance systems, such as the Norwegian one. Some physicians assert that the ethical obligations of the two roles conflict with each other. The objective of this article is to show that social insurance medical ethics, which are based on recognised principles of medical ethics, unite the physicians’ obligations associated with these roles. The method applied is a medical ethics conceptual analysis. The material consists of (...) literature on normative SIME. The study shows that SIME expands the role of the treatment provider to a wider societal context. Here, physicians should attempt to balance the perspectives of sympathy with empathy, as treatment providers, with the impartiality in their role as experts. Five principles of medical ethics are fundamental. Respect for human dignity is the overarching principle of medical ethics. The four others are nonmaleficence, beneficence, autonomy, and social justice. The article discusses two areas where it is asserted that the roles of treatment provider and expert conflict with each other: the application of beneficence and justice, and the duty of confidentiality versus the duty to provide information to the National Insurance service. The study concludes that there are no basic ethical conflicts between the two roles. The ethical problems that may arise when exercising this duality should be viewed in the same way as other ethical problems in medicine. Actual application and balancing of the principles may necessitate negotiations between patients and physicians. _ _Keywords_: dual roles, professionalism, deliberation, impartiality, medical principle ethics, values of welfare state.

For years analysts have recognized the error of assuming that experts in medical science are also experts in deciding the clinically correct course for patients. This paper extends the analysis of the use of the consensus of experts to their use in public policy groups such as NIH Consensus Development panels. After arguing that technical experts cannot be expected to be expert on public policy decisions, the author extends the criticism to the use of the consensus of experts in (...) estimating facts to provide a basis for policy decisions. It is argued that to the extent that (a) experts' views regarding a body of facts can be expected to correlate with their values relevant to those facts; and (b) the values of experts differ from the values of lay people, even the estimates of the facts given by the consensus of expert panels can be expected to differ from the estimates lay people would have given had they had the relevant scientific expertise.

Much work on the sense of agency has focused either on abnormal cases, such as delusions of control, or on simple action tasks in the laboratory. Few studies address the nature of the sense of agency in complex natural settings, or the effect of skill on the sense of agency. Working from 2 case studies of mountain bike riding, we argue that the sense of agency in high-skill individuals incorporates awareness of multiple causal influences on action outcomes. This allows fine-grained (...) differentiation of the contributions of self and external factors to action outcomes. We further argue that the sense of agency incorporates prospective awareness of actions that are possible in a situation and awareness of the limits of control. These forms of sense of agency enable highly flexible, context-sensitive strategic control, and are likely to contribute to high interindividual variability in responses to complex tasks. (shrink)

Abstract.The United Kingdom Department of Health initiative on “The Expert Patient” (2001) reflects recent trends in political philosophy, ethics and health services research. The overall objective of the initiative is to encourage patients, particularly those suffering from chronic conditions to become more actively involved in decisions concerning their treatment. In doing so there would be (perhaps) an expectation of better patient compliance and (arguably) a resultant improvement in quality of life. Despite these anticipated beneficial influences on health outcomes, there (...) may be a danger that such initiatives are being carried along by the general swell of enthusiasm for recognising and facilitating the claims of disadvantaged or discriminated against groups. What more attractive than that patients should be “liberated” from what might be seen as the oppression of medical paternalism? To a great extent the potential for success of the Expert Patient venture turns on:(a) whether and to what extent a patient can be considered truly to be an expert and (b) full acceptance by the medical and heath care professions of allowing patients a more equitable and positive role.Whilst clearly the patient is an expert in the hermeneutic sense – it is they and they alone who experience their illness – there is nevertheless a risk of confusing experience with expertise. Experience limited to an individual does not of itself give rise to the generalisations that underlie reliable clinical treatment. Neither do the vast majority of patients possess the physiological and pharmacological knowledge to fully appreciate the biological nature of their illness nor the basis, risks or limitations of therapeutic measures. Might the notion of “The Expert Patient” as informed co-decision maker become a well-meaning but rather vacuous aspiration similar to that of informed consent? Even worse, could patient “empowerment” have a deleterious effect? The paper reviews some of the major issues and concludes that the expert patient initiative could have benefits for both patients and health professionals if operated on the basis of concordance: an informed collaborative alliance that optimises the potential benefits of medical care.

The canonical history of mathematics suggests that the late 19th-century “arithmetization” of calculus marked a shift away from spatial-dynamic intuitions, grounding concepts in static, rigorous definitions. Instead, we argue that mathematicians, both historically and currently, rely on dynamic conceptualizations of mathematical concepts like continuity, limits, and functions. In this article, we present two studies of the role of dynamic conceptual systems in expert proof. The first is an analysis of co-speech gesture produced by mathematics graduate students while proving (...) a theorem, which reveals a reliance on dynamic conceptual resources. The second is a cognitive-historical case study of an incident in 19th-century mathematics that suggests a functional role for such dynamism in the reasoning of the renowned mathematician Augustin Cauchy. Taken together, these two studies indicate that essential concepts in calculus that have been defined entirely in abstract, static terms are nevertheless conceptualized dynamically, in both contemporary and historical practice.

The public can influence animal welfare law and regulation. However what constitutes ‘the public’ is not a straightforward matter. A variety of different publics have an interest in animal use and this has implications for the governance of animal welfare. This article presents an ethnographic content analysis of how the concept of a public is mobilized in animal welfare journals from 2003 to 2012. The study was undertaken to explore how experts in the discipline define and regard the role (...) of the public in determining animal welfare standards. Analysis indicates that experts in animal welfare constitute different types of citizen and consumer publics around specific types of animal use, framed by different theories of value. These results suggest a need for greater clarity about the roles and responsibilities of experts and publics in animal welfare reform processes. Clearly citizens and consumers can both contribute to promoting higher welfare standards, but an over-reliance on market mechanisms and consumer behaviour to assign value is beset by moral hazards, foremost being the risk of disarticulating the concept of animal welfare from the public good.

L’expertise se trouve bien souvent au cœur des dossiers judiciaires relatifs à la responsabilité en matière de santé publique. L’expert est chargé de reconstituer les faits ou d’évaluer le travail de ses collègues agissant comme conseillers des décideurs, pour établir si la qualité de l’expertise et du conseil a été à la hauteur des enjeux sanitaires. En France, les experts judiciaires ont un statut officiel à l’issue d’un processus réglementé et de contrôles spécifiques réguliers. Si cette procédure permet d’identifier (...) clairement les compétences des experts agréés, elle rend difficile, par sa lourdeur, l’accès des chercheurs à ce statut. Par ailleurs, des procédures plus claires permettant de séparer expertise et lobby devraient être mises en place.Expert appraisals are often crucial in legal proceedings concerning liability in matters of public health. Experts are required to reconstruct facts or to appraise the work of colleagues who act in an advisory capacity to policy-makers, in order to establish whether the quality of the expert studies and advice provided have been adequate to the importance of the health issues. In France, expert witnesses have an official status subject to a regulated procedure that includes specific and regular audits. Although this procedure clearly identifies the competences of court-appointed experts, it is far too lengthy and cumbersome for researchers to gain access to this status. Clearer procedures capable of distinguishing expert appraisals from lobbying also need to be established. (shrink)

The rapid advancement from single-gene testing to whole genome sequencing has significantly broadened the type and amount of information available to researchers, physicians, patients, and the public in general. Much debate has ensued about whether genomic test results should be reported to research participants, patients and consumers, and at what stage we can be sure that existing evidence justifies their use in clinical settings. Courts and judges evaluating the utility of these results will not be immune to this uncertainty. As (...) scholars increasingly explore the duty of care standards related to reporting genomic test results, it is timely to provide a framework for understanding how uncertainty about genetic and genomic tests influences evidentiary considerations in the court room. Here, we explore the subtleties and nuances of interpreting genetic data in an environment of substantial discord related to the value that individuals should place on genetic and genomic tests. In conjunction, we discuss the roles courts should play in qualifying experts, expert testimony, and genetic and genomic tests given the intricate and complex nature of genetic and genomic information.

Climate change adaptation is largely a local matter, and adaptation planning can benefit from local climate change projections. Such projections are typically generated by accepting climate model outputs in a relatively uncritical way. We argue, based on the IPCC’s treatment of model outputs from the CMIP5 ensemble, that this approach is unwarranted and that subjective expert judgment should play a central role in the provision of local climate change projections intended to support decision-making.

Scientific expert testimony is crucial to public deliberation, but it is associated with many pitfalls. This article identifies one—namely, expert trespassing testimony—which may be characterized, crudely, as the phenomenon of experts testifying outside their domain of expertise. My agenda is to provide a more precise characterization of this phenomenon and consider its ramifications for the role of science in society. I argue that expert trespassing testimony is both epistemically problematic and morally problematic. Specifically, I will argue (...) that scientific experts are subject to a particular obligation. Roughly, this is the obligation to qualify their assertions when speaking outside their domain of scientific expertise in certain contexts. Thus, I argue that scientists who possess expert knowledge are confronted with hard questions about when and how to testify and, therefore, that being a scientific expert comes with great responsibility. Consequently, I provide a concrete “expert guideline” according to which scientific experts, in certain contexts, face an obligation to qualify their assertions when speaking outside their domain of expertise. Furthermore, I consider a number of the conditions in which the guideline is waived or overridden. On this basis, I consider the broader aspects of the roles of scientific experts in a society with a high division of cognitive labor that calls for trust in scientific expert testimony. (shrink)

In this chapter, I survey and assess various answers to two basic questions concerning experts: (1) What is an expert?; (2) How can laypeople identify the relevant experts? These questions are not mutually independent, since the epistemology and the metaphysics of experts should go hand in hand. On the basis of our platitudes about experts, I will argue that the prevailing accounts of experts such as truth-linked, knowledge-linked, understanding-linked or service-oriented accounts are inadequate. In contrast, I will defend an (...) evidence-linked account of expertise. In the second part of the chapter, I address the question of how laypeople can identify experts in this sense. Here, I will argue that agreement among experts plays a major role. I will outline how laypeople can follow this criterion without running into circularity. (shrink)

Reasoning patterns found in Galileo’s treatise on machines, On Mechanics, are compared with patterns identified in case studies of scientifically trained experts thinking aloud, and many similarities are found. At one level the primary patterns identified are ordered analogy sequences and special diagrammatic techniques to support them. At a deeper level I develop constructs to describe patterns that can support embodied, imagistic, mental simulations as a central underlying process. Additionally, a larger hypothesized pattern of ‘progressive imagistic generalization’—Galileo’s development of a (...) model or mechanism that becomes more and more general with each machine while still being imagistically projectable into many machines—provides a way to think about his progress toward a modern explanatory model of torque. By unpacking his arguments, we gain an appreciation of his skillful ability to foster imagistic processes underlying scientific thinking. (shrink)

BackgroundGene drive technologies (GDTs) promote the rapid spread of a particular genetic element within a population of non-human organisms. Potential applications of GDTs include the control of insect vectors, invasive species and agricultural pests. Whether, and if so, under what conditions, GDTs should be deployed is hotly debated. Although broad stances in this debate have been described, the convictions that inform the moral views of the experts shaping these technologies and related policies have not been examined in depth in the (...) academic literature.MethodsIn this qualitative study, we interviewed GDT experts (n = 33) from different disciplines to identify and better understand their moral views regarding these technologies. The pseudonymized transcripts were analyzed thematically.ResultsThe respondents’ moral views were principally influenced by their attitudes towards (1) the uncertainty related to GDTs; (2) the alternatives to which they should be compared; and (3) the role humans should have in nature. Respondents agreed there is epistemic uncertainty related to GDTs, identified similar knowledge gaps, and stressed the importance of realistic expectations in discussions on GDTs. They disagreed about whether uncertainty provides a rationale to refrain from field trials (‘risks of intervention’ stance) or to proceed with phased testing to obtain more knowledge given the harms of the status quo (‘risks of non-intervention’ stance). With regards to alternatives to tackle vector-borne diseases, invasive species and agricultural pests, respondents disagreed about which alternatives should be considered (un)feasible and (in)sufficiently explored: conventional strategies (‘downstream solutions’ stance) or systematic changes to health care, political and agricultural systems (‘upstream solutions’ stance). Finally, respondents held different views on nature and whether the use of GDTs is compatible with humans’ role in nature (‘interference’ stance) or not (‘non-interference stance’).ConclusionsThis interview study helps to disentangle the debate on GDTs by providing a better understanding of the moral views of GDT experts. The obtained insights provide valuable stepping-stones for a constructive debate about underlying value conflicts and call attention to topics that deserve further (normative) reflection. Further evaluation of these issues can facilitate the debate on and responsible development of GDTs. (shrink)

This essay argues that current theories of action fail to explain agentive control because they have left out a psychological capacity central to control: attention. This makes it impossible to give a complete account of the mental antecedents that generate action.

In her book Democracy and Truth: The Conflict between Political and Epistemic Virtues, Snjezana Prijic Samarzija advocates that a purely procedural justification which defines the authority and legitimacy of democracy only in relation to the fairness of the procedure itself is not enough for a full justification of democracy. Some epistemic values should also be included. This epistemic quality of democracy depends on the quality of the decisions that the democratic procedures produce. In that sense, the author is advocating a (...) hybrid theory that secures harmony between political and epistemic values, favoring deliberative procedure for this purpose, and thus promotes equal respect for both democratic values.

It is generally accepted that the therapeutic relationship between professionals and patients is one of trust. Nonetheless, some patient groups carry certain social vulnerabilities that can be exacerbated when they extend trust to health-care professionals.

It critically evaluates the processes through which epistemic communities are formed or determined, and examines the (...) institutional structure and power relations that contribute to or sustain such self-affirming ideological communities. It also argues for a two-way collaborative approach between professionals and people with impairments that recognizes the role of local knowledge in enhancing professionals’ own understanding of their theoretical framework and promoting responsive practices and policies.

We report the results of an exploratory study that examines the judgments of climate scientists, climate policy experts, astrophysicists, and non-experts (N = 3367) about the factors that contribute to the creation and persistence of disagreement within climate science and astrophysics and about how one should respond to expert disagreement. We found that, as compared to non-experts, climate experts believe that within climate science (i) there is less disagreement about climate change, (ii) methodological factors play less of a (...) class='Hi'>role in generating disagreements, (iii) fewer personal or institutional biases influence climate research, and (iv) there is more agreement about which methods should be used to examine relevant phenomena we also observed that the uniquely American political context predicted experts’ judgments about some of these factors. We also found that, in regard to disagreements concerning cosmic ray physics, and commensurate with the greater inherent uncertainty and data lacunae in their field, astrophysicists working on cosmic rays were generally more willing to acknowledge expert disagreement, more open to the idea that a set of data can have multiple valid interpretations, and generally less quick to dismiss someone articulating a non-standard view as non-expert, than climate scientists were in regard to climate science.

We discuss the role of practical costs in the epistemic justification of a novice choosing expert advice, taking as a case study the choice of an expert statistician by a lay politician. First, we refine Goldman’s criteria for the assessment of this choice, showing how the costs of not being impartial impinge on the epistemic justification of the different actors involved in the choice. Then, drawing on two case studies, we discuss in which institutional setting the costs (...) of partiality can play an epistemic role. This way we intend to show how the sociological explanation of the choice of experts can incorporate its epistemic justification. (shrink)
