Learning more about philosophical cognition has yielded significant insights into the methods that we employ when doing philosophy, and has led some experimental philosophers to raise concerns about the role that intuitions play in philosophical practice. One popular response to these methodological concerns involves appeal to philosophical expertise, and has become known as the expertise defense because it aims to defend the use of at least some kinds of intuitional evidence in philosophy. The basic idea (...) is that philosophical expertise consists in having developed, through a process of critical reflection, increased conceptual competence and theoretical accuracy, as well as a special knack for reading and thinking about philosophical thought experiments that call upon us to exercise our conceptual competence and theoretical acumen. It turns out to be an open question whether this folk theory of philosophical expertise can restore hope in the value of intuitional evidence, and here we examine two ways of trying to answer that question: one that involves careful reflection on the supposed benefits of philosophical education, and one that involves careful empirical examination of “expert” philosophical intuitions.

Recent experimental studies indicate that epistemically irrelevant factors can skew our intuitions, and that some degree of scepticism about appealing to intuition in philosophy is warranted. In response, some have claimed that philosophers are experts in such a way as to vindicate their reliance on intuitions—this has become known as the ‘expertise defence’. This paper explores the viability of the expertise defence, and suggests that it can be partially vindicated. Arguing that extant discussion is problematically imprecise, we will (...) finesse the notion of ‘philosophical expertise’ in order to better reflect the complex reality of the different practices involved in philosophical inquiry. On this basis, we offer a new version of the expertise defence that allows for distinct types of philosophical expertise. The upshot of our approach is that wholesale vindications or rejections of the expertise defence are shown to be unwarranted; we must instead turn to local, piecemeal investigations of philosophical expertise. Lastly, in the spirit of taking our own advice, we exemplify how recent developments from experimental philosophy lend themselves to this approach, and can empirically support one instance of a successful expertise defence.

In what sense, if any, are philosophers experts in their domain of research and what could philosophical expertise be? The above questions are particularly pressing given recent methodological disputes in philosophy. The so-called expertise defense recently proposed as a reply to experimental philosophers postulates that philosophers are experts qua having improved intuitions. However, this model of philosophical expertise has been challenged by studies suggesting that philosophers’ intuitions are no less prone to biases and distortions than (...) intuitions of non-philosophers. Should we then give up on the idea that philosophers possess some sort of expertise? In this paper, I argue that instead of focusing on intuitions, we may understand the relevant results of philosophical practice more broadly and investigate the other kind of expertise they would require. My proposal is inspired by a prominent approach to investigating expert performance from psychology and suggests where and how to look for expertise in the results characteristic of philosophical practice. In developing this model, I discuss the following three candidates for such results: arguments, theories, and distinctions. Whether philosophers could be shown to be expert intuiters or not, there are interesting domains where we could look for philosophical expertise, beyond intuitions. (shrink)

Abstract: Some proponents of “experimental philosophy” criticize philosophers' use of thought experiments on the basis of evidence that the verdicts vary with truth-independent factors. However, their data concern the verdicts of philosophically untrained subjects. According to the expertise defence, what matters are the verdicts of trained philosophers, who are more likely to pay careful attention to the details of the scenario and track their relevance. In a recent article, Jonathan M. Weinberg and others reply to the expertise defence (...) that there is no evidence for such expertise. They now receive a reply in this article, which argues that they have misconstrued the dialectical situation. Since they have produced no evidence that philosophical training is less efficacious for thought experimentation than for other cognitive tasks for which they acknowledge that it produces genuine expertise, such as informal argumentation, they have produced no evidence for treating the former more sceptically than the latter.

Recent work in experimental philosophy has indicated that intuitions may be subject to several forms of bias, thereby casting doubt on the viability of intuition as an evidential source in philosophy. A common reply to these findings is the ‘expertise defense’ – the claim that although biases may be found in the intuitions of non-philosophers, persons with expertise in philosophy will be resistant to these biases. Much debate over the expertise defense has centered over the question of (...) the burden of proof; must defenders of expertise provide empirical evidence of its existence, or should we grant the existence of philosophical expertise as a ‘default’ assumption? Defenders have frequently appealed to analogy with other fields; since expertise clearly exists in, e.g., the sciences, we are entitled to assume its existence in philosophy. Recently, however, experimentalists have begun to provide empirical evidence that biases in intuition extend even to philosophers. Though these findings don't yet suffice to defeat the default assumption of expertise the analogy argument motivates, they do force any proponent of the analogy argument to provide more specific and empirically informed proposals for the possible nature of philosophical expertise. (shrink)

The so-called expertise defence against sceptical challenges from experimental philosophy has recently come under attack: there are several studies claiming to have found direct evidence that philosophers’ judgments in thought experiments are susceptible to erroneous effects. In this paper, we distinguish between the customary ‘immune experts’ version of the expertise defence and an ‘informed experts’ version. On the informed expertise defence, we argue, philosophers’ judgments in thought experiments could be preferable to those by the folk even if (...) it were true that philosophers’ judgments are no less immune to confounders than judgments by the folk are. We present results from an experimental study comparing philosophers and non-philosophers (n = 484), which support this version of the expertise defence. (shrink)

Philosophical expertise consists in knowledge, but it is controversial what this knowledge consists in. I focus on three issues: the extent and nature of knowledge of philosophical truths, how this philosophical knowledge is related to philosophical progress, and skeptical challenges to philosophical knowledge.

The “expertise defense” is the claim that philosophers have special expertise that allows them to resist the biases suggested by the findings of experimental philosophers. Typically, this defense is backed up by an analogy with expertise in science or other academic fields. Recently, however, studies have begun to suggest that philosophers' intuitions may be just as subject to inappropriate variation as those of the folk. Should we conclude that the expertise defense has been debunked? I'll argue (...) that the analogy with science still motivates a default assumption of philosophical expertise; however, the expertise so motivated is not expertise in intuition, and its existence would not suffice to answer the experimentalist challenge. I'll also suggest that there are deep parallels between the current methodological crisis in philosophy and the decline of introspection-based methods in psychology in the early twentieth century. The comparison can give us insight into the possible future evolution of philosoph.. (shrink)

In recent years a new discussion on the nature of philosophical expertise has emerged: whether philosophers possess a special kind of expertise, what such expertise would entail, how to measure it, and related concerns. The aim of the present article is to clarify certain related points across these debates in the hope of paving a clearer path forward, by addressing the following. (1) The expertise defense, which seems central to many discussions on methodology and (...) class='Hi'>expertise, has been misconstrued at times. (2) Questions of expertise and methodology could be separated more clearly. (3) The study of expertise may be important in its own right; however, there may be good reasons to give priority to methodological concerns. (4) Finally, when viewed in light of methodological concerns, a new project emerges when engaging with recent contributions to the expertise debate. The present article attempts a brief outline of this project. (shrink)

Appeals to intuitions as evidence in philosophy are challenged by experimental philosophers and other critics. A common response to experimental philosophical criticisms is to hold that only professional philosophers? intuitions count as evidence in philosophy. This ?expert intuitions defence? is inadequate for two reasons. First, recent studies indicate significant variability in professional philosophers? intuitions. Second, the academic literature on professional intuitions gives us reasons to doubt that professional philosophers develop truth-apt intuitions. The onus falls on those who mount the (...) expert intuitions defence to meet these objections because it is implicitly being claimed that training and practice caused professional philosophers to acquire reliably accurate intuitions and we are owed an account of how this transformation takes place. A possible response to this situation is to attempt to reform philosophical practice to improve the quality of intuitions. Another possible response, advocated here, is to avoid appeals to intuitions as evidence. (shrink)

Note: I asked undergraduate students, graduate students as well as assistant professors about how they would explain philosophical expertise. So don’t be surprised to find also statements of undergraduate students about philosophical expertise on this website. An analysis of the anonymous answers given on my website revealed that undergraduate students mentioned other abilities when it comes to philosophical expertise than assistent professors. Quite a few assistant professors agreed to answer some more detailed questions. They (...) are, however, still working on that. I will add their answers to this website as soon as I receive it.

My topic is two-fold: a reductive account of expertise as an epistemic phenomenon, and applying the reductive account to the question of whether or not philosophers enjoy expertise. I conclude, on the basis of the reductive account, that even though philosophers enjoy something akin to second-order expertise (i.e. they are often experts on the positions of other philosophers, current trends in the philosophical literature, the history of philosophy, conceptual analysis and so on), they nevertheless lack first-order (...) philosophical expertise (i.e. expertise on philosophical positions themselves such as the nature of mind, causality, normativity and so forth). Throughout the paper, I respond to potential objections. (shrink)

Recent empirical work appears to suggest that the moral intuitions of professional philosophers are just as vulnerable to distorting psychological factors as are those of ordinary people. This paper assesses these recent tests of the ‘expertise defense’ of philosophical intuition. I argue that the use of familiar cases and principles constitutes a methodological problem. Since these items are familiar to philosophers, but not ordinary people, the two subject groups do not confront identical cognitive tasks. Reflection on this point (...) shows that these findings do not threaten philosophical expertise—though we can draw lessons for more effective empirical tests. (shrink)

In some domains experts perform better than novices, and in other domains experts do not generally perform better than novices. According to empirical studies of expert performance, this is because the former but not the latter domains make available to training practitioners a direct form of learning feedback. Several philosophers resource this empirical literature to cast doubt on the quality of philosophical expertise. They claim that philosophy is like the dubious domains in that it does not make available (...) the good, direct kind of learning feedback, and thus there are empirical grounds for doubting the epistemic quality of philosophical expertise. I examine the empirical studies that are purportedly bad news for professional philosophers. On the basis of that examination, I provide three reasons why the empirical study of non-philosophical expertise does not undermine the status of philosophical expertise. First, the non-philosophical task-types from which the critics generalize are unrepresentative of relevant philosophical task-types. Second, empirical critiques of non-philosophical experts are often made relative to the performance of linear models—a comparison that is inapt in a philosophical context. Third, the critics fail to discuss findings from the empirical study of non-philosophical expertise that have more favorable implications for the epistemic status of philosophical expertise. In addition to discussing implications for philosophical expertise, this article makes progress in the philosophical analysis of the science of expertise and expert development. (shrink)

What does it mean to be an expert? What sort of authority do experts really have? And what role should they play in today's society? Addressing why ever larger segments of society are skeptical of what experts say, Expertise: A Philosophical Introduction reviews contemporary philosophical debates and introduces what an account of expertise needs to accomplish in order to be believed. Drawing on research from philosophers and sociologists, chapters explore widely held accounts of expertise and (...) uncover their limitations, outlining a set of conceptual criteria a successful account of expertise should meet. By providing suggestions for how a philosophy of expertise can inform practical disciplines such as politics, religion, and applied ethics, this timely introduction to a topic of pressing importance reveals what philosophical thinking about expertise can contribute to growing concerns about experts in the 21st century.

Gettier cases are scenarios conceived by philosophers to demonstrate that justified true beliefs may not be knowledge. Starmans and Friedman (2020) find that philosophers attribute knowledge in Gettier cases differently from laypeople and non‐philosophy academics, which seems to suggest that philosophers may be indoctrinated to adopt an esoteric concept of knowledge. I argue to the contrary: Their finding at most shows that philosophical reflection is fallible, but nevertheless able to clarify the concept of knowledge. I also suggest that their (...) experiments could be modified to help determine when philosophical reflection might yield plausible results. (shrink)

Rini 2015 [Synthese 192, (2): 431-452] claims to have identified a methodological flaw that invalidates the results of two experimental studies [Schwitzgebel & Cushman (2012) Mind and Language 27, (2): 135-153; Tobia, Buckwalter & Stich (2013) Philosophical Psychology 26, (5): 629–638] demonstrating order effects in professional philosophical intuition. This conclusion is reached on the basis of unsupported empirical premises for which no evidence is given. Subsequent findings in experimental cognitive science further reveal this as unsupported speculation.

We examined the effects of order of presentation on the moral judgments of professional philosophers and two comparison groups. All groups showed similar-sized order effects on their judgments about hypothetical moral scenarios targeting the doctrine of the double effect, the action-omission distinction, and the principle of moral luck. Philosophers' endorsements of related general moral principles were also substantially influenced by the order in which the hypothetical scenarios had previously been presented. Thus, philosophical expertise does not appear to enhance (...) the stability of moral judgments against this presumably unwanted source of bias, even given familiar types of cases and principles.

The Experimental Philosophy (“X-Phi”) movement applies the methodology of empirical sciences – most commonly empirical psychology – to traditional philosophical questions. In its radical, “negative” form, X-Phi uses the resulting empirical data to cast doubt on the reliability of common philosophical methods, arguing for radical reform of philosophical methodology.In this paper I develop two connected methodological worries about this second enterprise. The first concerns the data elicited by questionnaires and other empirical survey methods; recent work in political (...) science suggests that such surveys frequently do not elicit the participants’ candid judgements, but rather their expressions of certain attitudes and identifications. This possibility stymies the arguments from experimental data to a radical overhaul of philosophical methodology. The second builds on recent work by L.A. Paul and Kieran Healy concerning social science methodology, applying it to the use of those methods in X-Phi. It concerns experimental design where the treatment investigated is a “transformative” one; since a philosophical education is plausibly one such treatment, doubt is cast on any claim that apparent differences between the judgements of philosophers and ordinary folk has implications for philosophical methodology.

We examined the effects of framing and order of presentation on professional philosophers’ judgments about a moral puzzle case (the “trolley problem”) and a version of the Tversky & Kahneman “Asian disease” scenario. Professional philosophers exhibited substantial framing effects and order effects, and were no less subject to such effects than was a comparison group of non-philosopher academic participants. Framing and order effects were not reduced by a forced delay during which participants were encouraged to consider “different variants of the (...) scenario or different ways of describing the case”. Nor were framing and order effects lower among participants reporting familiarity with the trolley problem or with loss-aversion framing effects, nor among those reporting having had a stable opinion on the issues before participating the experiment, nor among those reporting expertise on the very issues in question. Thus, for these scenario types, neither framing effects nor order effects appear to be reduced even by high levels of academic expertise. (shrink)

This is a collective study of philosophical questions to do with experts and expertise, such as: What is an expert? Who decides who the experts are? Should we always defer to experts? How should expertise inform public policy? What happens when the experts disagree? Must experts be unbiased? Does it matter what the source of the expertise is?

There are many philosophical problems surrounding experts, given the power and status accorded to them in society. We think that what makes someone an expert is having expertise in some skill domain. But what does expertise consist in, and how closely related is expertise to the notion of an expert? Although most of us have acquired several practical skills, few of us have achieved the level of expertise with regard to those skills. So we can (...) be easily misled as to the nature of expertise, since it differs significantly from earlier stages of skill acquisition. Furthermore, this potential for misleading characterizations of skills and expertise leads to philosophers implicitly working with different conceptions of skills. This can interfere with their attempts to solve related problems about experts. In this paper I inquire into the nature of expertise, by drawing on recent psychological research on skill acquisition and expert performance. In addition, I connect this research on expertise to the larger context of psychological research on human cognition, as it will illuminate some of the differing elements of expertise. This allows me to then critique philosophical accounts of expertise, by showing how they make unwarranted assumptions about skills and expertise. Finally, I note the ways in which being credited as an expert can diverge from the possession of expertise itself. This can help us resist some of the power dynamics involved with those deemed to be experts. (shrink)

In a recent issue of Bioethics, Bernard Gesang asks whether a moral philosopher possesses greater moral expertise than a non-philosopher, and his answer is a qualified yes, based not so much on his infallible access to the truth, but on the quality of his theoretically-informed moral justifications. I reject Gesang's claim that there is such a thing as moral expertise, although the moral philosopher may well make a valid contribution to the ethics committee as a concerned and educated (...) citizen. I suggest that wisdom is a lot more interesting to examine than moral expertise. Again, however, moral philosophers have no monopoly on wisdom, and the study of philosophy may even impede its cultivation. (shrink)

Experimental philosophers have empirically challenged the connection between intuition and philosophical expertise. This paper reviews these challenges alongside other research findings in cognitive science on expert performance and argues for three claims. First, evidence taken to challenge philosophical expertise may also be explained by the well-researched failures and limitations of genuine expertise. Second, studying the failures and limitations of experts across many fields provides a promising research program upon which to base a new model of (...) philosophical expertise. Third, a model of philosophical expertise based on the limitations of genuine experts may suggest a series of constraints on the reliability of professional philosophical intuition. Even when the experts all agree, they may well be mistaken. — Bertrand Russell, On the Value of Scepticism. (shrink)

Using the bench trial of Colorado’s Amendment 2 as an example, this article focuses on the more general question of expert testimony in moral philosophy. It argues that there is indeed expertise in moral philosophy but argues against admitting such expert testimony in cases dealing with what John Rawls terms “constitutional essentials” and ‘matters of basic justice.” Developing the idea of public reason inherent in the Rawlsian concept of political liberalism, the article argues that philosophers can and should speak (...) out on public issues, if they do so with due respect for certain restrictions, but that they should not serve as expert witnesses on core constitutional questions, since doing so suggests that they claim a type of authority that would require fellow citizens to defer to their views. Such claims to authority in basic ethical matters threaten the mutual respect for divergent comprehensive doctrines that lies at the core of political liberalism. Philosophers have a duty to serve the public good, and they perform this service in fruitful ways. But they should refuse a public role that appears incompatible with equal respect for the committed ethical searching of their fellow citizens. (shrink)

Not only has knowledge been a central topic in philosophy, at least since Greek antiquity, but in recent years, it has been a prominent issue in the study of expertise. An important aspect of education is transmission of knowledge. This chapter discusses three views of expertise that have something important to say about the philosophical issues. It first briefly reviews the issue of defining and identifying expertise and the philosophical debate around knowing‐how and knowing‐that. After (...) presenting the key assumptions made by the three views on expertise, the chapter compares them along six philosophical dimensions: rationality, knowledge, intuition, introspection, deliberation and artificial intelligence. It focuses on performance‐based expertise (p‐expertise), drawing examples mostly from chess, where an objective and widely‐used measure of skill is available. Traditionally, philosophers have adopted a position known as intellectualism: explicit knowledge (aka knowing‐that) is the primary form of knowledge, and tacit knowledge (knowing‐how) derives from it.

Philosophers are often credited with particularly well-developed conceptual skills. The ‘expertise objection’ to experimental philosophy builds on this assumption to challenge inferences from findings about laypeople to conclusions about philosophers. We draw on psycholinguistics to develop and assess this objection. We examine whether philosophers are less or differently susceptible than laypersons to cognitive biases that affect how people understand verbal case descriptions and judge the cases described. We examine two possible sources of difference: Philosophers could be better at deploying (...) concepts, and this could make them less susceptible to comprehension biases (‘linguistic expertise objection’). Alternatively, exposure to different patterns of linguistic usage could render philosophers vulnerable to a fundamental comprehension bias, the linguistic salience bias, at different points (‘linguistic usage objection’). Together, these objections mount a novel ‘master argument’ against experimental philosophy. To develop and empirically assess this argument, we employ corpus analysis and distributional semantic analysis and elicit plausibility ratings from academic philosophers and psychology undergraduates. Our findings suggest philosophers are better at deploying concepts than laypeople but are susceptible to the linguistic salience bias to a similar extent and at similar points. We identify methodological consequences for experimental philosophy and for philosophical thought experiments. (shrink)

We all can identify many contemporary philosophy professors we know to be theists of some type or other. We also know that often enough their nontheistic beliefs are as epistemically upstanding as the non-theistic beliefs of philosophy professors who aren’t theists. In fact, the epistemic-andnon-theistic lives of philosophers who are theists are just as epistemically upstanding as the epistemic-and-non-theistic lives of philosophers who aren’t theists. Given these and other, similar, facts, there is good reason to think that the pro-theistic beliefs (...) of theistic philosophers are frequently epistemically upstanding. Given their impeccable epistemic credentials on non-theistic matters, the amount of careful thought that lies behind their theism, the large size of the community of philosophical theists, as well as other, similar facts, it would be surprising if all or even most of their pro-theistic beliefs were epistemically blameworthy in some or other signicant sense tied to charges such as ‘He should know better than to believe that’ (so mere false belief need not be blameworthy in this sense; the use of ‘blameworthy’ will be claried below). Of course some of the pro-theistic beliefs of some theistic philosophers are epistemically blameworthy; the mere large numbers of fallible theistic philosophers almost guarantees it. My point here is that it would be unexpected if most of the pro-theistic beliefs of theistic philosophers were epistemically blameworthy. (shrink)

This paper aims to vindicate the expertise defense in light of the experimental philosophy of free will. My central argument is that the analogy strategy between philosophy and other domains is defensible, at least in the free will debate, because philosophical training contributes to the formation of philosophical intuition by enabling expert philosophers to understand philosophical issues correctly and to have philosophical intuitions about them. This paper will begin by deriving two requirements on the (...) class='Hi'>expertise defense from major criticisms of it. First, precisely how philosophical training contributes to the formation of philosophical intuitions requires explanation (Contribution); second, it must be explained how philosophical training immunizes philosophical intuitions from distorting factors (Immunity). I shall argue that the Contribution requirement is crucial for the expertise defense and that this requirement can be satisfied at least in the domain of free will: recent research shows that most novices are unable to understand determinism correctly, suggesting that having intuitions about determinism requires philosophical expertise. I then discuss how this proposal can be applied to other philosophical disciplines. (shrink)

This paper explores the interconnections between philosophical wisdom and bioethical expertise, arguing that the latter can be enlightened by the former. First, it analyses the arguments of those who think that philosophy has nothing to say to bioethics, and afterwards, it shows that philosophical wisdom has an irreducible ethical component, which in turn helps bioethics to reach its aims. Thus, this paper shows that some Wittgensteinian commentators (e.g., Paul Johnston) did not grasp the contributions the author of (...) the Tractatus Logico-philosophicus and even his later work made to ethics (and potentially to bioethics as a subfield) as an autonomous domain of investigation independent of logic, the empirical sciences, and metaphysics.

In recent decades, the discipline of bioethics has grown rapidly, as has the practice of ethical consultation. Interestingly, this new recognition of the relevance of moral philosophy to our daily life has been accompanied by skepticism among philosophers regarding the existence of moral expertise or the benefits of philosophical training. In his recent article in Bioethics, William R. Smith suggested that this skepticism is rooted in philosophers' belief that moral expertise is inconsistent with liberal–democratic values, when in (...) fact they are compatible. In this paper, we provide a unique opportunity to empirically examine Smith's observation by utilizing and extending global data on philosophers' beliefs about moral expertise, involving 4087 philosophers from 96 countries. Our findings support Smith's theoretical observation and show that societal levels of support for liberal–democratic values are associated with greater skepticism about moral expertise. We suggest that these findings might be explained by the cognitive process of motivated reasoning and an invalid inference of “is” from “ought.” Consequently, the potential tension between moral expertise and liberal–democratic values is invalidly used for rejecting the existence of moral expertise, while its main and valid implication is for how moral expertise should be applied in liberal–democratic settings.

This brief essay explores how understanding the treatment of expert evidence requires engaging with its legal and political contexts, and not just focusing on its epistemological aspects. Although the law of evidence and thus its treatment of experts is significantly informed by epistemological considerations, it is also informed by concerns over the organization of trials, larger issues of intelligent governance, social concerns, and enforcement issues. These five aspects to the law of evidence give rise to principles to guide the explicit (...) structuring of the law of evidence that are identified here as well. This complexity helps to explain why the central issue of expert testimony is not the epistemological one of knowledge and belief but instead the conflict between educational and deferential modes of trial.

According to the ‘expertise defence’, experimental findings suggesting that intuitive judgments about hypothetical cases are influenced by philosophically irrelevant factors do not undermine their evidential use in (moral) philosophy. This defence assumes that philosophical experts are unlikely to be influenced by irrelevant factors. We discuss relevant findings from experimental metaphilosophy that largely tell against this assumption. To advance the debate, we present the most comprehensive experimental study of intuitive expertise in ethics to date, which tests five well- (...) known biases of judgment and decision-making among expert ethicists and laypeople. We found that even expert ethicists are affected by some of these biases, but also that they enjoy a slight advantage over laypeople in some cases. We discuss the implications of these results for the expertise defence, and conclude that they still do not support the defence as it is typically presented in (moral) philosophy. (shrink)

Many philosophers hold that experts’ semantic intuitions are more reliable and provide better evidence than lay people’s intuitions—a thesis commonly called “the Expertise Defense.” Focusing on the intuitions about the reference of proper names, this article critically assesses the Expertise Defense.

Philosophers of science are increasingly arguing for and addressing the need to do work that is socially and scientifically engaged. However, we currently lack well-developed frameworks for thinking about how we should engage other expert communities and what the epistemic benefits are of doing so. In this paper, I draw on Collins and Evans' concept of ‘interactional expertise’ – the ability to speak the language of a discipline in the absence of an ability to practice – to consider the (...) epistemic benefits that can arise when philosophers engage scientific communities. As Collins and Evans argue, becoming an interactional expert requires that one ‘hang out’ with members of the relevant expert community in order to learn crucial tacit knowledge needed to speak the language. Building on this work, I argue that acquiring interactional expertise not only leads to linguistic fluency, but it also confers several ‘socio-epistemic’ benefits such as the opportunity to cultivate trust with scientific communities. These benefits can improve philosophical work and facilitate the broader uptake of philosophers' ideas, enabling philosophers to meet a variety of epistemic goals. As a result, having at least some philosophers of science acquire interactional expertise via engagement will likely enhance the diversity of epistemic capacities for philosophy of science as a whole. For some philosophers of science, moreover, the socio-epistemic benefits identified here may be more important than the ability to speak the language of a discipline, suggesting the need for a broader analysis of interactional expertise, which this paper also advances.

Experimental restrictionists have challenged philosophers’ reliance on intuitions about thought experiment cases based on experimental findings. According to the expertise defense, only the intuitions of philosophical experts count—yet the bulk of experimental philosophy consists in studies with lay people. In this paper, we argue that direct strategies for assessing the expertise defense are preferable to indirect strategies. A direct argument in support of the expertise defense would have to show: first, that there is a significant difference (...) between expert and lay intuitions; second, that expert intuitions are superior to lay intuitions; and third, that expert intuitions accord with the relevant philosophical consensus. At present, there is only little experimental evidence that bears on these issues. To advance the debate, we conducted two new experiments on intuitions about knowledge with experts and lay people. Our results suggest that the intuitions of epistemological experts are superior in some respects, but they also pose an unexpected challenge to the expertise defense. Most strikingly, we found that even epistemological experts tend to ascribe knowledge in fake-barn-style cases. This suggests that philosophy, as a discipline, might fail to adequately map the intuitions of its expert practitioners onto a disciplinary consensus. (shrink)

Considerable attention in bioethics has been devoted to moral expertise and its implications for handling applied moral problems. The existence and nature of moral expertise has been a contested topic, and particularly, whether philosophers are moral experts. In this study, we put the question of philosophers’ moral expertise in a wider context, utilizing a novel and global study among 4,087 philosophers from 96 countries. We find that despite the skepticism in recent literature, the vast majority of philosophers (...) do believe in moral expertise and in the contribution of philosophical training and experience to its acquisition. Yet, they still differ on what philosophers’ moral expertise consists of. While they widely accept that philosophers possess superior analytic abilities regarding moral matters, they diverge on whether they also possess improved ability to judge moral problems. Nonetheless, most philosophers in our sample believe that philosophers possess an improved ability to both analyze and judge moral problems and that they commonly see these two capacities as going hand in hand. We also point at significant associations between personal and professional attributes and philosophers’ beliefs, such as age, working in the field of moral philosophy, public involvement, and association with the analytic tradition. We discuss the implications of these findings for the debate about moral expertise. -/- . (shrink)

Philosophers have harbored doubts about the possibility of moral expertise since Plato. I argue that irrespective of whether moral experts exist, identifying who those experts are is insurmountable because of the credentials problem: Moral experts have no need to seek out others’ moral expertise, but moral non-experts lack sufficient knowledge to determine whether the advice provided by a putative moral expert in response to complex moral situations is correct and hence whether an individual is a bone fide expert. (...) Traditional accounts of moral expertise require that moral experts give reliably correct moral advice supported by adequate justification, an account which, I argue, is too lean in allowing for the possibility of a moral expert who is motivationally indifferent to her own moral judgments and advice. Yet even if the proposition that a moral expert is an individual who provides reliably correct moral advice supported by adequate justification and is necessarily motivated by that advice exhausts the necessary and sufficient conditions for moral expertise, this proposition cannot function as an applicable criterion for non-experts to use in appraising would-be experts’ claims to expertise. The credentials problem thus remains unanswered. (shrink)

Philosophers and others have questioned whether or not expertise in morality is possible. This debate is not only theoretical, but also affects the perceived legitimacy of clinical ethicists. One argument against moral expertise is that in a pluralistic society with competing moral theories no one can claim expertise regarding what another ought morally to do. There are simply too many reasonable moral values and intuitions that affect theory choice and its application; expertise is epistemically uniform. In (...) this article, we discuss how similar concerns have recently threatened to undermine expertise in medicine and science. In contrast, we argue that the application of values is needed to exercise medical, scientific, and moral expertise. As long as these values are made explicit, worries about a pretense to authority in the context of a liberal democracy are ill-conceived. In conclusion, we argue for an expertise that is epistemically diverse. (shrink)

Philosophers, particularly moral philosophers, are increasingly being involved in public decision‐making in areas which are seen to raise ethical issues. For example, Dame Mary Warnock chaired the ‘Committee of Inquiry into Human Fertilization and Embryology’ in the UK in 1982–4; the Philosophy Department at Auckland was commissioned by the Auckland Regional Authority to report on the ethical aspects of fluoridating the public water supply in 1990; and many of us are serving on ethics committees of various sorts. Not only are (...) philosophers actually being called on or consulted, but many of us would argue that a philosophical contribution in such areas is essential.The involvement of moral philosophers in public policy decisions raises a question of professional ethics, viz, what role should a philosopher's own moral perspective or judgements play in the advice s/he gives, or contribution s/he makes, to public decision‐making on ethical issues. Like most problems in professional ethics, this prompts reflection on the nature of the profession, and in particular on the expertise we take moral philosophy to offer. It also prompts reflection on how processes of public decision making in ethically problematic areas should be understood. I explore these issues in this paper. (shrink)

Trust is a central concept in the philosophy of science. We highlight how trust is important in the wide variety of interactions between science and society. We claim that examining and clarifying the nature and role of trust (and distrust) in relations between science and society is one principal way in which the philosophy of science is socially relevant. We argue that philosophers of science should extend their efforts to develop normative conceptions of trust that can serve to facilitate trust (...) between scientific experts and ordinary citizens. The first project is the development of a rich normative theory of expertise and experience that can explain why the various epistemic insights of diverse actors should be trusted in certain contexts and how credibility deficits can be bridged. The second project is the development of concepts that explain why, in certain cases, ordinary citizens may distrust science, which should inform how philosophers of science conceive of the formulation of science policy when conditions of distrust prevail. The third project is the analysis of cases of successful relations of trust between scientists and non-scientists that leads to understanding better how ‘postnormal’ science interactions are possible using trust.

Experimental philosophers have challenged friends of the expertise defense to show that the intuitive judgments of professional philosophers are different from the intuitive judgments of nonphilosophers, and the intuitive judgments of professional philosophers are better than the intuitive judgments of nonphilosophers, in ways that are relevant to the truth or falsity of such judgments. Friends of the expertise defense have responded by arguing that the burden of proof lies with experimental philosophers. This article sketches three arguments which show (...) that both and are probably false. If its arguments are cogent, then shifting the burden of proof is a futile move, since philosophical training makes no difference so far as making intuitive judgments in response to hypothetical cases is concerned.
