In this article, we analyse the evidential value of the corpus of experimental philosophy. While experimental philosophers claim that their studies provide insight into philosophical problems, some philosophers and psychologists have expressed concerns that the findings from these studies lack evidential value. Barriers to evidential value include selection bias and p-hacking. To find out whether the significant findings in x-phi papers result from selection bias or p-hacking, we applied a p-curve analysis to a corpus of 365 x-phi (...) chapters and articles. Our results suggest that this corpus has evidential value, although there are hints of p-hacking in a few parts of the x-phi corpus. (shrink)

Recent developments in experimental philosophy (‘x-phi’) suggest that there is a new way in which the empirical and normative dimensions of bioethics can be brought into successful dialogue with one another. It revolves around conceptual analysis – though not the kind of conceptual analysis one might perform in an armchair. Following Édouard Machery, this is Conceptual Analysis Rebooted. In short, morally-pertinent medical concepts like ‘treatment’, ‘euthanasia’ and ‘sanctity of life’ can each have several meanings that underwrite inferences with (...) different moral implications. X-phi shows us that an experimental approach to conceptual analysis can make explicit the implicit structures that underpin our thinking about such concepts. By presenting concrete examples, I aim to offer a glimpse of an empirically-grounded, practically-normative 'bioxphi' that demystifies and distinguishes medical concepts, assesses the normative inferences these concepts dispose us to draw and revises those inferences that are deficient.

Using two decades worth of experimental philosophy (aka x-phi), Edouard Machery argues in Philosophy within its Proper Bounds (OUP, 2017) that philosophers’ use of the “method of cases” is unreliable because it has a strong tendency to elicit different intuitive responses from non-philosophers. And because, as Machery argues, appealing to such cases is usually the only way for philosophers to acquire the kind of knowledge they seek, an extensive philosophical skepticism follows. I argue that Machery’s “Unreliability” argument (...) fails because, once its premises are percisified, they are either self-defeating or without justification. This is a significant result because Machery’s arguments are the most widely cited and discussed x-phi arguments for philosophical skepticism and many hold that Machery provides the most empirically informed, convincing, and thus best case for this kind of skepticism. So, if my arguments are sound, then the best x-phi argument for philosophical skepticism fails. I further argue that this result provides strong reason to believe the more general conclusion that “negative” x-phi is likely doomed: x-phi likely can never support a substantive philosophical skepticism. Ultimately, I argue for the broad conclusion that all empirically minded arguments for philosophical skepticism are likely to fail for the same reasons that Machery’s does, i.e. they are (likely) self-defeating.

The rise of experimental philosophy has placed metaphilosophical questions, particularly those concerning concepts, at the center of philosophical attention. X-phi offers empirically rigorous methods for identifying conceptual content, but what exactly it contributes towards evaluating conceptual content remains unclear. We show how x-phi complements Rudolf Carnap’s underappreciated methodology for concept determination, explication. This clarifies and extends x-phi’s positive philosophical import, and also exhibits explication’s broad appeal. But there is a potential problem: Carnap’s account of explication was limited to (...) empirical and logical concepts, but many concepts of interest to philosophers are essentially normative. With formal epistemology as a case study, we show how x-phi assisted explication can apply to normative domains. (shrink)

One central purpose of Experimental Philosophy (hereafter, x-phi) is to criticize the alleged reliance on intuitions in contemporary philosophy. In my book Philosophy without Intuitions (hereafter, PWI), I argue that philosophers don’t rely on intuitions. If those arguments are good, experimental philosophy has been engaged in an attack on a strawman. The goal of this paper is to bolster the criticism of x-phi in the light of responses.

Ad hoc concepts feature prominently in lexical pragmatics. A speaker can use a word or phrase to communicate an ad hoc concept that is different from the lexically encoded concept and the hearer can construct the intended ad hoc concept pragmatically during utterance comprehension. I argue that some philosophical concepts have origins as ad hoc concepts, and such concepts pose a challenge for experimental philosophy regarding these concepts. To illustrate this, I consider philosophers’ ‘what-it’s-like’-concepts and experimental (...) class='Hi'>philosophy of consciousness. (shrink)

Experimental philosophy is often regarded as a category mistake. Even those who reject that view typically see it as irrelevant to standard philosophical projects. We argue that neither of these claims can be sustained and illustrate our view with a sketch of the rich interconnections with philosophy of science.Keywords: Science; Philosophy; Experimental Philosophy.

This paper discusses “impartiality thought experiments”, i.e., thought experiments that attempt to generate intuitions which are unaffected by personal characteristics such as age, gender or race. We focus on the most prominent impartiality thought experiment, the Veil of Ignorance (VOI), and show that both in its original Rawlsian version and in a more generic version, empirical investigations can be normatively relevant in two ways: First, on the assumption that the VOI is effective and robust, if subjects dominantly favor a certain (...) normative judgment behind the VOI this provides evidence in favor of that judgment; if, on the other hand, they do not dominantly favor a judgment this reduces our justification for it. Second, empirical investigations can also contribute to assessing the effectiveness and robustness of the VOI in the first place, thereby supporting or undermining its applications across the board.

I will here sharply oppose all the phases of the story Schaffer & Knobe tell. In Part 1 we will look at the supposed empirical case against standard contextualism, and in Part 2 we will investigate Schaffer & Knobe’s supposed empirical case for the superiority of contrastivism over standard contextualism.

Ethics isn’t a conversation exclusive to philosophers. There is value, then, in not only understanding how laypeople think about issues in ethics, but also bringing their judgments into dialogue with those of philosophers in order to make sense of agreement, disagreement, and the consequences of each. Experimental philosophers facilitate this dialogue uniquely by capturing laypeople’s judgments and analyzing them in light of philosophical theory. They have done so almost exclusively by using face valid quantitative surveys about philosophically interesting thought (...) experiments. Based on high participant support for this or that response, researchers conclude that a given theory is more or less intuitive, and in some cases that it is or isn’t true. However, such conclusions can only be drawn from quantitative survey data if one assumes those data accurately reflect laypeople’s thinking on the issues of interest, an assumption that can’t be justified by the quantitative data itself since they are potentially opaque. This is the methodological problem of experimental philosophy: experimental philosophers who use quantitative methods alone can’t sufficiently demonstrate their data to be reflective of relevant judgments/intuitions. To better explore people’s judgments on issues in ethics and to determine whether experimental philosophers are or aren’t getting what they take themselves to be getting in surveys, I recreated part of an experiment by Chituc, Henne, Sinnott-Armstrong, and De Brigard on the Kantian principle that “ought implies can”, or that whenever an agent ought to do something then it is the case that she can, and added a layer of qualitative data to it by having participants think aloud while completing the surveys and conduct a follow-up interview. With similar quantitative results to those from Chituc et al., I argue that my qualitative results 1) cast doubt on Chituc et al.’s data being reflective of many people’s judgments, especially on the more interesting questions relating to moral obligation; 2) reveal unique insights into how people think about OIC; 3) generally speak to the value of experimental philosophers using triangulation of methods in better understanding laypeople’s complex and varied thinking about questions important to ethics and beyond. Supplemental documents: Appendices A, B, C, D, and E are surveys I used in my study. Appendices C and D are derived from Chituc et al.’s publication “Blame, Not Ability, Impacts Moral ‘Ought’ Judgments for Impossible Actions: Toward an Empirical Refutation of ‘Ought’ Implies ‘Can.’” Appendix F is the recruitment flyer I distributed for my study. Appendix H is the quantitative data from my study. (shrink)

This paper does two things. First, it argues for a metaphilosophical view of conceptual analysis questions; in particular, it argues that the facts that settle conceptual-analysis questions are facts about the linguistic intentions of ordinary folk. The second thing this paper does is argue that if this metaphilosophical view is correct, then experimental philosophy is a legitimate methodology to use in trying to answer conceptual-analysis questions.

When philosophers study knowledge, consciousness, free will, moral value, and so on, their first concern is with these things themselves, rather than with what people think about them. So why exactly is it so important to philosophy to discover experimentally that people differ in their views on these matters? We wouldn’t expect physicists to throw up their hands in excitement just because somebody shows that different cultures have different views about the origin of the universe.

Prominent critics and champions of Experimental Philosophy (X-Phi) alike have tied its philosophical significance to the philosophical significance of intuition. In this essay, I develop an interpretation of X-Phi which does not require an intuition-driven understanding of traditional philosophy, and the arguments challenged by results in X-Phi. X-Phi's role on this account is primarily dialectical. Its aim is to test the universality of claims which are merely assumed to be true, exploring the limits of our assumptions and (...) showing when a proposition is more controversial than is widely believed.

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.

This chapter tries to elucidate the complex relationship between ordinary language philosophyordinary language philosophy (OLP) and experimental philosophy (X-Phi) from the perspective of the contrast between the positive and the negative programs of X-Phi. I will first show the relevance of language to the various fields of contemporary philosophy, through what I call the Argument from Cross-Linguistic Diversity and the Argument from Intra-Linguistic Variance, together with empirical data. This will partly vindicate OLP, which is generally thought (...) to be obsolete today. I will then examine the reasons for the demise of OLP, and show that the contemporary meta-philosophical debates over X-Phi are in fact a revival of the debates in the heyday of OLP. This will then also indicate a parallel between Wittgenstein’s negative programnegative program, called quietism, and the negative program of X-Phi, especially Stich’s. The positive program of X-Phi can no doubt contribute to science, but the question of whether it is philosophy may depend on our conception of philosophy. The negative program of X-Phi is no doubt philosophy, but the question is whether it can make any positive contribution to philosophy, let alone science. I will answer “yes” to it, by sketching a radical negative picture of philosophy in general. (shrink)

Much of the recent movement organized under the heading “Experimental Philosophy” has been concerned with the empirical study of responses to thought experiments drawn from the literature on philosophical analysis. I consider what bearing these studies have on the traditional projects in which thought experiments have been used in philosophy. This will help to answer the question what the relation is between Experimental Philosophy and philosophy, whether it is an “exciting new style of [philosophical] (...) research”, “a new interdisciplinary field that uses methods normally associated with psychology to investigate questions normally associated with philosophy” (Knobe et al. 2012), or whether its relation to philosophy consists, as some have suggested, in no more than the word ‘philosophy’ appearing in its title, or whether the truth lies somewhere in between these two views. I first distinguishes different strands in Experimental Philosophy, negative and positive x-phi, and x-phi pursuing philosophy as opposed to x-phi as cognitive science. Next I review some ways in which Experimental Philosophy has been criticized. Finally, I consider what would have to be true for Experimental Philosophy to have one or another sort of relevance to philosophy, whether the assumptions required are true, how we could know it, and the ideal limits of the usefulness Experimental Philosophy to philosophy. I conclude x-phi cannot in principle be a replacement for traditional first person approaches because it yields the wrong kind of knowledge and that it can nonetheless be a practical aid in conducting philosophical thought experiments. n.

In the mid-seventeenth century a movement of self-styled experimental philosophers emerged in Britain. Originating in the discipline of natural philosophy amongst Fellows of the fledgling Royal Society of London, it soon spread to medicine and by the eighteenth century had impacted moral and political philosophy and even aesthetics. Early modern experimental philosophers gave epistemic priority to observation and experiment over theorising and speculation. They decried the use of hypotheses and system-building without recourse to experiment and, in (...) some quarters, developed a philosophy of experiment. The movement spread to the Netherlands and France in the early eighteenth century and later impacted Germany. Its important role in early modern philosophy was subsequently eclipsed by the widespread adoption of the Kantian historiography of modern philosophy, which emphasised the distinction between rationalism and empiricism and had no place for the historical phenomenon of early modern experimental philosophy. The re-emergence of interest in early modern experimental philosophy roughly coincided with the development of contemporary x-phi and there are some important similarities between the two. (shrink)

Objectivity, as one of the key attributes of science, has become an indispensable part of its ethos and a central theme of the philosophy of science. As such, it has been a subject of philosophical reflection by a number of authors. In our project – in which both philosophers of science and scientists participate – we examine the concept of objectivity in the natural sciences with the tools of experimental philosophy. We aim to identify specific operational dimensions (...) of objectivity, those with which current scientist actually work, thus making them accessible for further theoretical analysis and research. In this text, we present results from the first, qualitative phase of our research based on in-depth interviews and focus groups with scientists working in the Czech Republic. Further, we confront this empirical data with theoretical notions of objectivity. We also present other findings from the research and formulate hypotheses for the research’s subsequent phases.

Responding to recent concerns about the reliability of the published literature in psychology and other disciplines, we formed the X-Phi Replicability Project to estimate the reproducibility of experimental philosophy. Drawing on a representative sample of 40 x-phi studies published between 2003 and 2015, we enlisted 20 research teams across 8 countries to conduct a high-quality replication of each study in order to compare the results to the original published findings. We found that x-phi studies – as represented in (...) our sample – successfully replicated about 70% of the time. We discuss possible reasons for this relatively high replication rate in the field of experimental philosophy and offer suggestions for best research practices going forward. (shrink)

Experimental moral philosophy emerged as a methodology in the last decade of the twentieth century, as a branch of the larger experimental philosophy (X-Phi) approach. Experimental moral philosophy is the empirical study of moral intuitions, judgments, and behaviors. Like other forms of experimental philosophy, it involves gathering data using experimental methods and using these data to substantiate, undermine, or revise philosophical theories. In this case, the theories in question concern the nature (...) of moral reasoning and judgment; the extent and sources of moral obligations; the nature of a good person and a good life; even the scope and nature of moral theory itself. This entry begins with a brief look at the historical uses of empirical data in moral theory and goes on to ask what, if anything, is distinctive about experimental moral philosophy—how should we distinguish it from related work in empirical moral psychology? After discussing some strategies for answering this question, the entry examines two of the main projects within experimental moral philosophy, and then discusses some of the most prominent areas of research within the field. As we will see, in some cases experimental moral philosophy has opened up new avenues of investigation, while in other cases it has influenced longstanding debates within moral theory. (shrink)

ABSTRACT Conceptual engineering provides a prima facie attractive alternative to traditional, conceptual analysis based approaches to philosophical method – particularly for those with doubts about the epistemic merits of intuition. As such, it seems to be a natural fit for those persuaded by the critiques of intuition offered by experimental philosophy. Recently, a number of authors [Schupbach, J. 2015. “Experimental Explication.” Philosophy and Phenomenological Research 94 : 672–710; Shepherd, J., and J. Justus. 2015. “X-Phi and Carnapian (...) Explication.” Erkenntnis 80 : 381–402; Fisher, J. 2015. “Pragmatic Experimental Philosophy.” Philosophical Psychology 28: 412–433; Machery, E. 2017. Philosophy Within its Proper Bounds. Oxford University Press] have suggested that experimental philosophy might be employed in service of conceptual engineering. In this paper, I provide a novel argument for x-phi’s relevance to conceptual engineering, based on a ‘functionalist’ approach to conceptual engineering. In short, I argue that experimental philosophy is distinctively well-suited to investigation of the purposes or functions which our concepts serve, and the means by which they fulfil those functions. Experimental philosophy thereby uncovers potential engineering solutions that may serve as models for the conceptual engineer. (shrink)

ABSTRACT In Philosophy Within its Proper Bounds, Édouard Machery argues that the results of experimental philosophy should lead us to abandon much of traditional philosophical practice. In its place Machery defends naturalized conceptual analysis as a more modest and pragmatic alternative to standard analytic philosophy. This paper argues that Machery overstates the metaphilosophical significance of x-phi’s results. We can and should keep many of the insights and good methodological habits that come with x-phi. However, if one (...) is not already convinced of pragmatism or naturalism, the discoveries of x-phi are unlikely to make too much difference to one’s metaphilosophical position. (shrink)

Experimental philosophy (or “x-phi”) is a way of doing philosophy. It is “traditional” philosophy, but with a little something extra: In addition to the expected philosophical arguments and engagement, x-phi involves the use of empirical methods to test the empirical claims that arise. This extra bit strikes some as a new, perhaps radical, addition to philosophical practice. We don’t think so. As this chapter will show, empirical claims have been common across the history of Western (...) class='Hi'>philosophy, as have appeals to empirical observation in attempting to support or subvert these claims. While conceptions of philosophy have changed over time, across these changes we find philosophers employing empirical methods in pursuing their philosophical questions. Our primary aim in this chapter is to illustrate this fact. We begin by discussing the relevance of history to experimental philosophy (Section 2), then offer a necessarily condensed and highly selective history of empirical work in Western philosophy, ranging from the ancients (Section 3), to the early moderns (Section 4), to the late moderns (Section 5), and on to the present (Section 6).

Since the earliest days of analytic philosophy, it has been a common practice to appeal to intuitions about particular cases. Typically, the philosopher presents a hypothetical situation and then makes a claim of the form: ‘In this case, we would surely say....’ This claim about people’s intuitions then forms a part of an argument for some more general theory about the nature of our concepts or our use of language. One puzzling aspect of this practice is that it so (...) rarely makes use of standard empirical methods. Although philosophers quite frequently make claims about ‘what people would ordinarily say,’ they rarely back up those claims by actually asking people and looking for patterns in their responses. In recent years, however, a number of philosophers have tried to put claims about intuitions to the test, using experimental methods to figure out what people really think about particular hypothetical cases. At times, the results have been extremely surprising. Here I discuss applications of this new methodology to three areas of philosophy — the philosophy of language, the theory of action, and the free will debate. (shrink)

This chapter proceeds from the standard picture of the relation between intuitions and experimental philosophy: the alleged evidential role of intuitions about hypothetical cases, and experimental philosophy’s challenge to these judgments, based on their variation with philosophically irrelevant factors. I will survey some of the main defenses of this standard picture against the x-phi challenge, most of which fail. Concerning the most popular defense, the expertise defense, I will draw the bleak conclusion that intuitive expertise of (...) the envisaged kind is largely a myth. Next, I will consider the mischaracterization objection, which has mainly been developed by Deutsch and Cappelen on the basis of textual evidence: that philosophers do not appeal to intuitions as evidence for their case judgments, but instead argue for them. This would render the x-phi challenge mostly irrelevant, due to its focus on intuitions about hypothetical cases. I will then consider a few instructive replies to the mischaracterization objection, which are all unconvincing on further inspection. Finally, I will discuss some potential normative consequences of the mischaracterization objection, and I will argue that it recommends a shift away from the excessive focus on intuitions about cases in metaphilosophy and experimental philosophy, towards more work on the role of argumentation in the method of cases. More speculatively, I claim that philosophers should always argue for their case judgments, even if they have strong intuitions about them, because an argument-based methodology would be more transparent and philosophically fruitful than one that mainly relies on intuition.

In this paper I will discuss some issues related to a recent trend in experimental philosophy (or x-phi), and try to show the reasons of its late (and scarce) involvement with aesthetics, compared to other areas of philosophical investigation. In order to do this, it is first necessary to ask how an autonomous experimental philosophy of aesthetics could be related to the long-standing tradition of psychological experimental aesthetics. After distinguishing between a “narrow” and a “broad” (...) approach of experimental philosophy, I will then make a distinction between topics in aesthetics pertaining to perceptual and cognitive processes, and traditional issues involved in the analysis of general and culturally-laden concepts. The narrow program of experimental philosophy, focused on the investigation of folk intuitions, is particularly effective only when two general conditions are met: the use of hypothetical scenarios (testing of thought experiments) and the heuristic role of folk intuitions in drawing philosophically relevant conclusions. I will argue that, when aesthetics is concerned, these requirements are not easily met. These difficulties notwithstanding, I will support a pluralistic view where aesthetics is revealed as an instructive example of how experimental approaches and traditional “armchair” philosophy integrate, and enrich each other.

In recent years, developments in experimental philosophy have led many thinkers to reconsider their central assumptions and methods. It is not enough to speculate and introspect from the armchair - philosophers must subject their claims to scientific scrutiny, looking at evidence and in some cases conducting new empirical research. "The Theory and Practice of Experimental Philosophy" is an introduction and guide to the systematic collection and analysis of empirical data in academic philosophy. This book serves (...) two purposes: first, it examines the theory behind “x-phi,” including its underlying motivations and the objections that have been leveled against it. Second, the book offers a practical guide for those interested in doing experimental philosophy, detailing how to design, implement, and analyze empirical studies. Thus, the book explains the reasoning behind x-phi and provides tools to help readers become experimental philosophers. (shrink)

Experimental philosophy is a new and somewhat controversial method of philosophical inquiry in which philosophers conduct experiments in order to shed light on issues of philosophical interest. This typically involves surveying ordinary people to find out their "intuitions" (roughly, pre-theoretical judgments) about hypothetical cases important to philosophical theorizing. The controversy surrounding this methodology arises largely because it departs from more traditional ways of doing philosophy. Moreover, some of its practitioners have used it to argue that the more (...) traditional methods are flawed. In Experimental Philosophy, Joshua Knobe and Shaun Nichols are set with the task of introducing readers to this burgeoning field by putting together a collection of some of its most important articles. Given how controversial it has become, this is a heavy burden. I'm happy to say that they have put together a valuable collection that serves as a diplomatic introduction to this exciting new style of research. (shrink)

Recent years have seen the development of an approach both to general philosophy and philosophy of science often referred to as ‘experimental philosophy’ or just ‘X-Phi’. Philosophers often make or presuppose empirical claims about how people would react to hypothetical cases, but their evidence for claims about what ‘we’ would say is usually very limited indeed. Philosophers of science have largely relied on their more or less intimate knowledge of their field of study to draw hypothetical (...) conclusions about the state of scientific concepts and the nature of conceptual change in science. What they are lacking is some more objective quantitative data supporting their hypotheses. A growing number of philosophers , along with a few psychologists and anthropologists, have tried to remedy this situation by designing experiments aimed at systematically exploring people’s reactions to philosophically important thought experiments or scientists’ use of their scientific concepts. Many of the results have been surprising and some of the conclusions drawn from them have been more than a bit provocative. This symposium attempts to provide a window into this new field of philosophical inquiry and to show how experimental philosophy provides crucial tools for the philosopher and encourages two-way interactions between scientists and philosophers.Keywords: Experimental philosophy; Naturalism; Continuity thesis; Philosophy of science; Quantitative data.

Experimental Philosophy (X-Phi) is now a fully-fledged methodological project with applications in almost all areas of analytic philosophy, including, as of recently, aesthetics. Another methodological project which has been attracting attention in the last few years is conceptual engineering (CE). Its areas of implementation are now diverse, but as was the case initially with experimental philosophy, aesthetics has unfortunately been left out (or perhaps aestheticians have failed to pay attention to CE) until now. In this (...) paper, I argue that if conceptual engineers are interested in expanding their project to the field of aesthetics, which would greatly benefit the field, then they should rely on the existing experimental work of aestheticians. Experimental philosophers have only recently started to join forces with conceptual engineers in various fields, as well as to explore the methodological implications of such an alliance. This paper goes a step further by not only arguing that CE has potential in aesthetics, but that the way to realize this potential is to piggyback, so to speak, on the work of experimental aestheticians. In other words, instead of building a CE project in aesthetics from the ground up, this paper describes the support that CE can and should derive from current experimental aesthetics, thereby making the former’s development more efficiently realizable. Furthermore, I argue that doing so would also be beneficial to experimental aesthetics. Currently, the integration of X-Phi to the wider field of aesthetics is losing ground because certain objections—notably, the objection that X-Phi cannot be of relevance to normative questions—have not been properly refuted. By pairing up with a normative programme like CE, though, experimental aestheticians should finally be able to put these objections to rest. (shrink)

Experimental philosophy is one of the most controversial and potentially revolutionary areas of philosophical research today. X-Phi, as it is known by many of its practitioners, questions many basic concepts regarding human intuitions—concepts which have guided centuries of modern philosophers. In their place, x-phi steers philosophical research back to scientific investigations in order to better understand human intuitions, using research techniques borrowed from current research in psychology and neuroscience. While scholars debate whether experimental philosophy signals a (...) sea change or is merely a faddish detour, no existing book looks at the X-Phi movement in reference to its methodology. In _The Experimental Turn and the Methods of Philosophy_, Michael J.Shaffer addresses this need, suggesting that the significance of experimental philosophy can best be assessed and understood in methodological terms. By comparing and contrasting traditional views of philosophical methodology with those of experimental philosophy, Shaffer traces the roots of the movement to Quinean naturalism and also demonstrates the deep, revolutionary significance of the experimental turn.

The time has come to consider whether experimental philosophy’s (“x-phi”) early arguments, debates, and conceptual frameworks, that may have worn well in its early days, fit with the diverse range of projects undertaken by experimental philosophers. Our aim is to propose a novel taxonomy for x-phi that identifies four paths from empirical findings to philosophical consequences, which we call the “fourfold route.” We show how this taxonomy can be fruitfully applied even at what one might have taken (...) to be the furthest edges of possible applications of x-phi in metaphysics and formal philosophy. Ultimately, the fourfold route helps us understand a different kind of empirical fact: the development of x-phi itself. (shrink)

This entry summarizes an emerging subdiscipline of both empirical bioethics and experimental philosophy (“x-phi”) which has variously been referred to as experimental philosophical bioethics, experimental bioethics, or simply “bioxphi”. Like empirical bioethics, bioxphi uses data-driven research methods to capture what various stakeholders think (feel, judge, etc.) about moral issues of relevance to bioethics. However, like its other parent discipline of x-phi, bioxphi tends to favor experiment-based designs drawn from the cognitive sciences – including psychology, neuroscience, and (...) behavioral economics – to tease out why and how stakeholders think as they do.

The movement called Experimental Philosophy (‘x-Phi’) has now passed its tenth anniversary. Its central insight is compelling: When an argument hinges on accepting certain ‘facts’ about human perception, knowledge, or judging, the evoking of relevant intuitions by thought experiments is intended to make those facts seem obvious. But these intuitions may not be shared universally. Experimentalists propose testing claims that traditionally were intuition-based using real experiments, with real samples. Demanding that empirical claims be empirically supported is certainly reasonable; (...) though experiments are not necessarily the only means available. When experiments are conducted, adequately interpreting their results requires understanding the study’s design (and possibly flaws) that produced them. Experiment-based reports should document the design clearly. If Plato, writing his Meno, replaced accounts of Socrates demonstrating geometry to a slave-boy, with a survey of 100 real boys—some grasping his demonstrations, others not—what conclusions could be reached? Before answering, the reader needs details on key design questions, including (among others): (a) What population are these samples intended to represent? (E.g., ‘all slave boys’?; ‘math-ignorant people’?; ‘everyone’?) (b) What statistical tests were conducted, on what assumptions? (c) How was ‘significance’ of results determined? (d) Was the test instrument’s validity established? For readers wishing to explore x-Phi’s potentials, as contributors or as interpreters of their findings, this paper offers some cautionary considerations. Throughout their literature, examples can be found casting doubt on some experimentalists’ findings, due to design-related issues. Increased awareness of methodological questions would tighten the x-phi literature, going forward . (shrink)

Debates about the genuine disease status of controversial diseases rely on intuitions about a range of factors. Adopting tools from experimental philosophy, this paper explores some of the factors that influence judgments about whether low sexual desire should be considered a disease and whether it should be medically treated. Drawing in part on some assumptions underpinning a divide in the literature between viewing low sexual desire as a genuine disease and seeing it as improperly medicalized, we investigate whether (...) health and disease judgments are affected by factors such as an individual’s gender, the cause of the low desire, whether the desire is high or low, and both personal and societal valuations of the condition. Our main findings indicate that (a) the cause of a condition influences whether it is judged a disorder, (b) how the individual values the condition influences whether the condition is seen as a proper target of medical intervention, and (c) perceived dysfunction influences judgments regarding health, disorder classification, medicalization, and medical intervention. Our findings help further illuminate the intricate interplay of factors that influence judgments about health and disease in controversial conditions. (shrink)

Wie kann ein Experiment zur Beantwortung philosophischer Fragestellungen beitragen? Etwa: Was ist Wissen? Was bedeuten sprachliche Ausdrücke? Haben wir einen freien Willen?

Vertreter einer jungen philosophischen Bewegung wollen den Fragen ihres Fachs mithilfe empirisch-psychologischer Methoden auf den Grund gehen. Anstatt den Lehnstuhl (»armchair«) aufzusuchen, um sich philosophischen Problemen zu widmen, begeben sich experimentelle Philosophen ins Labor, um mithilfe empirischer Informationen aus Psychologie, Neurowissenschaft und Kognitionswissenschaft philosophische Schlussfolgerungen zu stützen. Die Einführung gibt (...) einen anschaulichen Einblick in das neue Forschungsfeld der XPhi und stellt wichtige experimentelle Beiträge zur Erkenntnistheorie, Sprachphilosophie, Philosophie des Geistes und Handlungstheorie vor.

This work explores the impact of negative X-Phi in the philosophical practice of relying on intuitions. After analyzing how intuitions work, their different types and how they orient thought, I argue that there are several interesting ways for philosophy to deal with the abundance of intuitions that sometimes are in conflict. The emerging image is one where philosophy responds directly or indirectly to truth and doesn't have in intuitions its sole evidential basis.Resumo: O texto explora o impacto da (...) filosofia experimental negativa na prática filosófica de se balizar em intuições. Após uma análise de como funcionam as intuições, dos seus diferentes tipos e de como elas orientam o pensamento, argumento que há modos interessantes da filosofia conviver com a abundância de intuições, muitas vezes contrastantes e em conflito. A imagem que emerge é que a filosofia não tem nas intuições sua única base de evidência e que ela responde, antes, direta ou indiretamente à verdade de suas teses. (shrink)

Much of experimental philosophy consists of surveying 'folk' intuitions about philosophically relevant issues. Are the results of these surveys evidence that the relevant folk intuitions cannot be predicted from the ‘armchair’? We found that a solid majority of philosophers could predict even results claimed to be 'surprising'. But, we argue, this does not mean that such experiments have no role at all in philosophy.

This volume presents new research on the use of experimental methodologies in moral and social philosophy. The contributions reflect the growing plurality of methodologies and strategies for implementing experimental work on morality to new domains, problems, and topics. Philosophers are exploring the ways in which empirical approaches can transform our idea of the good, our understanding of the social nature of norms and morality, as well as our methods of fulfilling ethical goals. The chapters in this volume (...) extend experimental work on morality to previously underexplored areas. The contributions in Part 1 explore the methods and foundations of experimental work in areas such as folk moral judgments, metaethical beliefs, moral explanations, and reflective equilibrium. Part 2 focuses on issues in normative ethics, legal, and political philosophy such as virtue ethics, utilitarianism, theories of justice, and criminal responsibility. Finally, the chapters in Part 3 tackle various applied ethical issues including feminist X-Phi, animal welfare, experimental bioethics, and self-driving cars. Experiments in Moral and Political Philosophy will be of interest to scholars and advanced students working in ethics, applied ethics, experimental philosophy, social and political philosophy, and philosophy of law.

Some ethicists believe that we should give no weight to low-level intuitions about cases. In this paper, three common arguments for this position are examined and rejected. All have an empirical basis. The first is the argument from disagreement. The second draws on framing effects. And the third employs debunking explanations. The discussion aims to make a substantive methodological point about ethical inquiry, viz. that low-level intuitions are not to be shunned. Above that, however, its aim is to illuminate, by (...) way of illustration, the relation between empirical findings and normative conclusions – a link that is rather intricate and can only be explored through armchair reflection.

The larger philosophical world has on the whole turned from a mix of averted gaze and outright antipathy toward x‐phi, to a mix of grudging acceptance and enthusiastic embrace. This chapter explains that the experimental philosophy is relevant, and that it is dangerous, and explains some ways that people can do more to remain both. Experimental philosophy's semi‐official sigil of the burning armchair has advertised its dangerousness for the past decade and a half as well. The (...) chapter explains that it is a threat that is every bit as potently present in positive program x‐phi as it is in negative program work. To explore the idea that experimental philosophy's positive contributions will still be primarily negative in nature, the chapter interrogates the passage from Timothy Williamson. It focuses on the wheat‐from‐chaff project of separating signal from noise in the evidence produced by intuitions and the like. (shrink)

Our interest in this paper is to drive a wedge of contention between two different programs that fall under the umbrella of “experimental philosophy”. In particular, we argue that experimental philosophy’s “negative program” presents almost as significant a challenge to its “positive program” as it does to more traditional analytic philosophy.

Plausibly, how much is at stake in some salient practical task can affect how generously people ascribe knowledge of task-relevant facts. There is a metaphysical puzzle about this phenomenon, and an empirical puzzle. Metaphysically: there are competing theories about when and how practical stakes affect whether it is correct to ascribe knowledge. Which of these theories is the right one? Empirically: experimental philosophy has struggled to find a stakes-effect on people’s knowledge ascriptions. Is the alleged phenomenon just a (...) philosopher’s fantasy? I propose a new psychological account of when and why people’s knowledge ascriptions are sensitive to stakes. My hypothesis is motivated by empirical research on how people’s judgements are sensitive to their social context. Specifically, people’s evaluations are sensitive to their ‘psychological distance’ from the scenarios they are considering. When using ‘fixed-evidence probes’, experimental philosophy has found that what’s at stake for a fictional character in a made-up scenario has little or no effect on how participants ascribe knowledge to them. My hypothesis predicts this finding: the scenarios are too ‘psychologically distant’ to participants. Our empirical puzzle is resolved: the stakes-effect often present in the wild won’t be present in vignette studies. (This illustrates a widespread problem with X-phi vignette studies: if people might judge differently in other social contexts, we can’t generalize from the results of these experiments. That is, vignette studies are of doubtful ‘external validity’.) The hypothesis also resolves our metaphysical puzzle. It predicts that people do not ascribe knowledge in a way deemed correct by any of the standard philosophical views, namely classical invariantism, interest-relative invariantism, and contextualism. Our knowledge ascriptions shift around in the way that’s most useful for social beings like us, and this pattern in our judgements can only be endorsed by a genuinely relativist metaphysics for knowledge.

This paper criticizes an influential argument from Thomas Nagel’s THE POSSIBILTIY OF ALTRUISM, an argument that plays a foundational role in the philosophies of (at least) Philippa Foot, John McDowell and Jonathan Dancy. Nagel purports to prove that a person can be can be motivated to perform X by the belief that X is likely to bring about Y, without a causally active or biffy desire for Y. If Cullity and Gaut are to be believed (ETHICS AND PRACTICAL REASONING) this (...) is widely regarded within the practical reasoning industry as an established fact. My thesis is a simple one. Nagel’s argument is an abject failure and the philosophies that are founded on it are built upon sand. There is a little bit of rather amateurish X-Phi at the end, but I don’t want readers to get too excited about this as it is essentially icing on the cake. This paper is not primarily an exercise in Experimental Philosophy but in Baby Logic, and it’s central thesis is a logical one, namely that Nagel (to put the point politely) fails to prove his thesis.

This book explores how the trans phenomenon can challenge the existing concept of the Self and its nature. The catalyst is Moore’s Paradox: can a trans person coherently state ‘I am a girl but I don’t believe that’? More deeply, three fundamental philosophical questions arise, of ontological, epistemological, and conceptual significance: what Self understands that the natal-gender is ‘wrong’? How does the trans person know that the natal-gender is ‘wrong’ and what counts as evidence? And finally, how does this effect (...) the concept of Self itself? Seeking answers, Brakel considers various theories of the Self, including classical accounts, modern views, and models developed by selected gender theorists. The book then takes a biological turn, first developing an evolutionary proper-function analysis of gender and trans-gender and subsequently proposing the possibility of a new ontological phenotype. With a review of cutting-edge neuroscientific research conducted over the last twenty-five years, Brakel propels this timely and important investigation toward the future, using experimental philosophy empirical studies adapted from classic thought experiments on the nature of the Self.
