Various studies show moral intuitions to be susceptible to framing effects. Many have argued that this susceptibility is a sign of unreliability and that this poses a methodological challenge for moral philosophy. Recently, doubt has been cast on this idea. It has been argued that extant evidence of framing effects does not show that moral intuitions have an unreliability problem. I argue that, even if the extant evidence suggests that moral intuitions are fairly stable with respect to what intuitions we (...) have, the effect of framing on the strength of those intuitions still needs to be taken into account. I argue that this by itself poses a methodological challenge for moral philosophy. (shrink)

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)

This is the most comprehensive book ever published on philosophical methodology. A team of thirty-eight of the world's leading philosophers present original essays on various aspects of how philosophy should be and is done. The first part is devoted to broad traditions and approaches to philosophical methodology. The entries in the second part address topics in philosophical methodology, such as intuitions, conceptual analysis, and transcendental arguments. The third part of the book is devoted to essays about the interconnections between philosophy (...) and neighbouring fields, including those of mathematics, psychology, literature and film, and neuroscience.

Rose and Schaffer (forthcoming) argue that teleological thinking has a substantial influence on folk intuitions about composition. They take this to show (i) that we should not rely on folk intuitions about composition and (ii) that we therefore should not reject theories of composition on the basis of intuitions about composition. We cast doubt on the teleological interpretation of folk judgments about composition; we show how their debunking argument can be resisted, even on the assumption that folk intuitions have a (...) teleological source; and we argue that, even if folk intuitions about composition carry no weight, theories of composition can still be rejected on the basis of the intuitions of metaphysicians.

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)

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. (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)

Many epistemologists think we can derive important theoretical insights by investigating the English word ‘know’ or the concept it expresses. However, fewer than six percent of the world’s population are native English speakers, and some empirical evidence suggests that the concept of knowledge is culturally relative. So why should we think that facts about the word ‘know’ or the concept it expresses have important ramifications for epistemology? This paper argues that the concept of knowledge is universal: it is expressed by (...) some word in every natural language. I also explore the implications of this thesis for philosophical methodology. (shrink)

Nearly all success is due to some mix of ability and luck. But some successes we attribute to the agent’s ability, whereas others we attribute to luck. To better understand the criteria distinguishing credit from luck, we conducted a series of four studies on knowledge attributions. Knowledge is an achievement that involves reaching the truth. But many factors affecting the truth are beyond our control and reaching the truth is often partly due to luck. Which sorts of luck are compatible (...) with knowledge? We find that knowledge attributions are highly sensitive to lucky events that change the explanation for why a belief is true. By contrast, knowledge attributions are surprisingly insensitive to lucky events that threaten but ultimately fail to change the explanation for why a belief is true. These results shed light on our concept of knowledge, help explain apparent inconsistencies in prior work on knowledge attributions, and constitute progress toward a general understanding of the relation between success and luck.

To address the underrepresentation of women in philosophy effectively, we must understand the causes of the early loss of women. In this paper we challenge one of the few explanations that has focused on why women might leave philosophy at early stages. Wesley Buckwalter and Stephen Stich offer some evidence that women have different intuitions than men about philosophical thought experiments. We present some concerns about their evidence and we discuss our own study, in which we attempted to replicate their (...) results for 23 different responses to 14 scenarios . We also conducted a literature search to see if other philosophers or psychologists have tested for gender differences in philosophical intuitions. Based on our findings, we argue that that it is unlikely that gender differences in intuitions play a significant role in driving women from philosophy. (shrink)

Radical skepticism is the view that we know nothing or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an interaction between two (...) factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e., that something is not the case) than when it is positive (i.e., that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

In one of the earlier influential papers in the field of experimental philosophy titled Normativity and Epistemic Intuitions published in 2001, Jonathan M. Weinberg, Shaun Nichols and Stephen Stich reported that respondents answered Gettier type questions differently depending on their ethnic background as well as socioeconomic status. There is currently a debate going on, on the significance of the results of Weinberg et al. (2001) and its implications for philosophical methodology in general and epistemology in specific. Despite the debates, however, (...) to our knowledge, there has not been a replication attempt of the experiments of the original paper. We collected data from four different sources (two on-line and two in-person) to replicate the experiments. Despite several different data sets and in various cases larger sample sizes and hence greater power to detect differences, we failed to detect significant differences between the above-mentioned ethnic and socioeconomic groups. Our results suggest that epistemic intuitions are more robust across ethnic and socioeconomic groups than Weinberg et al. (2001) indicates. Given our data, we believe that the notion of differences in epistemic intuitions among different ethnic and socioeconomic groups that follows from Weinberg et al. (2001) needs to be corrected.

Intuitively, there is a difference between knowledge and mere belief. Contemporary philosophical work on the nature of this difference has focused on scenarios known as “Gettier cases.” Designed as counterexamples to the classical theory that knowledge is justified true belief, these cases feature agents who arrive at true beliefs in ways which seem reasonable or justified, while nevertheless seeming to lack knowledge. Prior empirical investigation of these cases has raised questions about whether lay people generally share philosophers’ intuitions about these (...) cases, or whether lay intuitions vary depending on individual factors (e.g. ethnicity) or factors related to specific types of Gettier cases (e.g. cases that include apparent evidence). We report an experiment on lay attributions of knowledge and justification for a wide range of Gettier Cases and for a related class of controversial cases known as Skeptical Pressure cases, which are also thought by philosophers to elicit intuitive denials of knowledge. Although participants rated true beliefs in Gettier and Skeptical Pressure cases as being justified, they were significantly less likely to attribute knowledge for these cases than for matched true belief cases. This pattern of response was consistent across different variations of Gettier cases and did not vary by ethnicity or gender, although attributions of justification were found to be positively related to measures of empathy. These findings therefore suggest that across demographic groups, laypeople share similar epistemic concepts with philosophers, recognizing a difference between knowledge and justified true belief.

Do epistemic intuitions tell us anything about knowledge? Stich has argued that we respond to cases according to our contingent cultural programming, and not in a manner that tends to reveal anything significant about knowledge itself. I’ve argued that a cross-culturally universal capacity for mindreading produces the intuitive sense that the subject of a case has or lacks knowledge. This paper responds to Stich’s charge that mindreading is cross-culturally varied in a way that will strip epistemic intuitions of their evidential (...) value. I argue that existing work on cross-cultural variation in mindreading favors my position over Stich’s. (shrink)

One mainstream approach to philosophy involves trying to learn about philosophically interesting, non-mental phenomena—ethical properties, for example, or causation—by gathering data from human beings. I call this approach “wide tent traditionalism.” It is associated with the use of philosophers’ intuitions as data, the making of deductive arguments from this data, and the gathering of intuitions by eliciting reactions to often quite bizarre thought experiments. These methods have been criticized—I consider experimental philosophy’s call for a move away from the use of (...) philosophers’ intuitions as evidence, and recent suggestions about the use of inductive arguments in philosophy—and these criticisms point out important areas for improvement. However, embracing these reforms in turn gives wide-tent traditionalists strong reasons to maintain other traditional approaches to philosophy. Specifically, traditionalists’ commitment to using intuitions and to gathering them with bizarre thought experiments is well founded, both philosophically and empirically. I end by considering some problems with gathering trustworthy intuitions, and give suggestions about how best to solve them. (shrink)

Many epistemologists use intuitive responses to particular cases as evidence for their theories. Recently, experimental philosophers have challenged the evidential value of intuitions, suggesting that our responses to particular cases are unstable, inconsistent with the responses of the untrained, and swayed by factors such as ethnicity and gender. This paper presents evidence that neither gender nor ethnicity influence epistemic intuitions, and that the standard responses to Gettier cases and the like are widely shared. It argues that epistemic intuitions are produced (...) by the natural ‘mindreading’ capacity that underpins ordinary attributions of belief and knowledge in everyday social interaction. Although this capacity is fallible, its weaknesses are similar to the weaknesses of natural capacities such as sensory perception. Experimentalists who do not wish to be skeptical about ordinary empirical methods have no good reason to be skeptical about epistemic intuitions. (shrink)

To a large extent, the evidential base of claims in the philosophy of science has switched from thought experiments to case studies. We argue that abandoning thought experiments was a wrong turn, since they can effectively complement case studies. We make our argument via an analogy with the relationship between experiments and observations within science. Just as experiments and ‘natural’ observations can together evidence claims in science, each mitigating the downsides of the other, so too can thought experiments and case (...) studies be mutually supporting. After presenting the main argument, we look at potential concerns about thought experiments, suggesting that a judiciously applied mixed-methods approach can overcome them. (shrink)

This work investigates intuitions' nature, demonstrating how philosophers can best use them in epistemology. First, the author considers several paradigmatic thought experiments in epistemology that depict the appeal to intuition. He then argues that the nature of thought experiment-generated intuitions is not best explained by an a priori Platonism. Second, the book instead develops and argues for a thin conception of epistemic intuitions. The account maintains that intuition is neither a priori nor a posteriori but multi-dimensional. It is an intentional (...) but non-propositional mental state that is also non-conceptual and non-phenomenal in nature. Moreover, this state is individuated by its progenitor, namely, the relevant thought experiment. Third, the author provides an argument for the evidential status of intuitions based on the correct account of the nature of epistemic intuition. The suggestion is the fitting-ness approach: intuition alone has no epistemic status. Rather, intuition has evidentiary value as long as it fits well with other pieces into a whole, namely, the pertinent thought experiment. Finally, the book addresses the key challenges raised by supporters of anti-centrality, according to which philosophers do not regard intuition as central evidence in philosophy. To that end, the author responds to them, showing that they fail to affect the account of intuition developed in this book. This text appeals to students and researchers working in epistemology.

In the recent literature, several authors have argued that the capacity to track factive mental states plays a central role in explaining our ability to understand and predict people’s behavior (Nagel 2013; Nagel 2017; Phillips & Norby 2019; Phillips et al. 2020; Westra & Nagel 2021). The topic of this chapter is whether this capacity also enters into an explanation of our ability to track skilled and intentional actions.

In recent years, the epistemic reliability of moral intuitions has been undermined by substantial empirical data reporting the influence of cognitive biases. This paper discusses and elaborates upon a promising strategy in response to the reliability challenge to moral intuitions. The considered argument appeals to the fact that moral intuitions are experienced with different levels of strength and agents accept only strong intuitions, not vulnerable to bias under realistic circumstances. This essay aims to reconstruct this defense from the reliability challenge (...) in its most promising form and to evaluate the plausibility of the argument in light of the available empirical evidence. What emerges from the discussion is that the vindication of moral intuitions fundamentally depends on two distinct premises: first, the hypothesis that agents accept moral intuitions proportionally to their level of confidence, and second, the hypothesis that intuitive confidence is epistemically reliable. While there is consistent evidence for the first hypothesis, there is still no conclusive evidence for the second. (shrink)

Epistemologists have long believed that epistemic luck undermines propositional knowledge. Action theorists have long believed that agentive luck undermines intentional action. But is there a relationship between agentive luck and epistemic luck? While agentive luck and epistemic luck have been widely thought to be independent phenomena, we argue that agentive luck has an epistemic dimension. We present several thought experiments where epistemic luck seems to undermine both knowledge-how and intentional action and we report experimental results that corroborate these judgments. These (...) findings have implications for the role of knowledge in a theory of intentional action and for debates about the nature of knowledge-how and the significance of knowledge representation in folk psychology.

Moral intuitions are generally understood as automatic strong responses to moral facts. In this paper, I offer a metacognitive account according to which the strength of moral intuitions denotes the level of confidence of a subject. Confidence is a metacognitive appraisal of the fluency with which a subject processes information from a morally salient stimulus. I show that this account is supported by some empirical evidence, explains the main features of moral intuition and is preferable to emotional or quasi-perceptual views (...) of moral intuition.

Financial incentives, learning, group consultation, and increased experimental control are among the experimental techniques economists have successfully used to deflect the behavioral challenge posed by research conducted by such scholars as Tversky and Kahneman. These techniques save the economic armchair to the extent that they align laypeople judgments with economic theory by increasing cognitive effort and reflection in experimental subjects. It is natural to hypothesize that a similar strategy might work to address the experimental or restrictionist challenge to armchair philosophy. (...) To test this hypothesis, a randomized controlled experiment was carried out, as well as two lab experiments. Three types of knowledge attribution tasks were used. No support for the hypothesis was found. The paper describes the close similarities between the economist’s response to the behavioral challenge, and the expertise defense against the experimental challenge, and presents the experiments, results, and an array of robustness checks. The upshot is that these results make the experimental challenge all the more forceful. (shrink)

The Nash counterfactual considers the question: what would happen were I to change my behaviour assuming no one else does. By contrast, the Kantian counterfactual considers the question: what would happen were everyone to deviate from some behaviour. We present a model that endogenizes the decision to engage in this type of Kantian reasoning. Autonomous agents using this moral framework receive psychic payoffs equivalent to the cooperate-cooperate payoff in Prisoner’s Dilemma regardless of the other player’s action. Moreover, if both interacting (...) agents play Prisoner’s Dilemma using this moral framework, their material outcomes are a Pareto improvement over the Nash equilibrium. (shrink)

This chapter reviews some faults of the theoretical literature and findings from the experimental literature on “Gettier” cases. Some “Gettier” cases are so poorly constructed that they are unsuitable for serious study. Some longstanding assumptions about how people tend to judge “Gettier” cases are false. Some “Gettier” cases are judged similarly to paradigmatic ignorance, whereas others are judged similarly to paradigmatic knowledge, rendering it a theoretically useless category. Experimental procedures can affect how people judge “Gettier” cases. Some important central tendencies (...) in judging “Gettier” cases appear to be robust against demographic variation in biological sex, age, language, and culture, although there could be some interesting differences related to culture and personality traits. Some remaining questions regarding Gettier’s cases, “Gettier” cases, and “the Gettier problem” concern the psychology and sociology of contemporary anglophone theoretical epistemology. Some remaining questions regarding the empirical study of knowledge judgments concern mechanisms underlying observed behavioral patterns. (shrink)

We examine a prominent naturalistic line on the method of cases, exemplified by Timothy Williamson and Edouard Machery: MoC is given a fallibilist and non-exceptionalist treatment, accommodating moderate modal skepticism. But Gettier cases are in dispute: Williamson takes them to induce substantive philosophical knowledge; Machery claims that the ambitious use of MoC should be abandoned entirely. We defend an intermediate position. We offer an internal critique of Macherian pessimism about Gettier cases. Most crucially, we argue that Gettier cases needn’t exhibit (...) ‘disturbing characteristics’ that Machery posits to explain why philosophical cases induce dubious judgments. It follows, we show, that Machery’s central argument for the effective abandonment of MoC is undermined. Nevertheless, we engineer a restricted variant of the argument—in harmony with Williamsonian ideology–that survives our critique, potentially limiting philosophy’s scope for establishing especially ambitious modal theses, despite traditional MoC’s utility being partially preserved.

Recent empirical studies raise methodological concerns about the use of intuitions in philosophy. According to one prominent line of reply, these concerns are unwarranted since the empirical studies motivating them do not control for the putatively characteristic phenomenology of intuitions. This paper makes use of research on metacognitive states that have precisely this phenomenology to argue that the above reply fails. Furthermore, it shows that empirical findings about these metacognitive states can help philosophers make better informed assessments of their warrant (...) for relying on intuitions in inquiry.

ABSTRACT The use of intuitions as evidence is widespread in epistemology, but not uncontroversial. For over a decade and a half, some experimental epistemologists have called into question this appeal to epistemic intuitions. These philosophers bring the methods of experimental psychology, in particular survey methods, to bear on epistemological theorizing. Given their commitment to the relevance of empirical work to philosophical theory construction, they qualify as methodological naturalists. But some methodological naturalists who also recommend giving up appeals to intuition as (...) evidence do not base their case on experimental surveys. In this article I consider two main challenges to the standard practice of appealing to intuitions posed by these naturalist philosophers and argue that a Craig-style epistemological project can allow the methodological naturalist to address them. Anyway I conclude that, regardless of the truth of the Craigian approach, intuitions still have a role to play in epistemological theorizing in the adjudication between approaches. (shrink)

We report a series of experiments examining whether people ascribe knowledge for true beliefs based on probabilistic evidence. Participants were less likely to ascribe knowledge for beliefs based on probabilistic evidence than for beliefs based on perceptual evidence or testimony providing causal information. Denial of knowledge for beliefs based on probabilistic evidence did not arise because participants viewed such beliefs as unjustified, nor because such beliefs leave open the possibility of error. These findings rule out traditional philosophical accounts for why (...) probabilistic evidence does not produce knowledge. The experiments instead suggest that people deny knowledge because they distrust drawing conclusions about an individual based on reasoning about the population to which it belongs, a tendency previously identified by “judgment and decision making” researchers. Consistent with this, participants were more willing to ascribe knowledge for beliefs based on probabilistic evidence that is specific to a particular case. 2016 APA, all rights reserved). (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.

One recent trend in contemporary epistemology is to study the way in which the concept of knowledge is actually applied in everyday settings. This approach has inspired an exciting new spirit of collaboration between experimental philosophers and traditional epistemologists, who have begun using the techniques of the social sciences to investigate the factors that influence ordinary judgments about knowledge attribution. This paper provides an overview of some of the results these researchers have uncovered, suggesting that in addition to traditionally considered (...) factors like evidence and justification, a number of important non-truth-conducive factors play significant roles in determining when people ascribe knowledge. The present review focuses on four non-traditional factors: pragmatic load (in relation to contextualism and interest-relative invariantism), moral judgment, performance errors, and demographic variation.

The focus of this paper will be to examine the implications that a “practical” approach to conceptual engineering might have for the “traditional” conception of philosophy as uncovering truths about phenomena of philosophical interest. In doing so, I will be building on the ideas of a figure that many take to be the first major philosopher to write on conceptual engineering: Rudolf Carnap. Though the current wave of interest in conceptual engineering goes back less than a decade, many conceptual engineers (...) have found precedent for their views in Carnap’s characterization of what he called “explication.” Interestingly, however, not nearly as much attention has been paid to another Carnapian thesis which seems to me to have deep relevance to methodological questions about conceptual engineering. I have in mind here the distinction between internal and external questions proposed in “Empiricism, Semantics and Ontology” (1950b) and the accompanying claim that external questions lack cognitive content and can be cogently approached only as a matter of pragmatic decision-making. This is the aspect of Carnap’s views upon which I propose to build. I'll first make the case that there is a suggestive similarity between Carnap’s claim that external questions are matters of pragmatic choice and the practical conceptual engineer’s claim that engineering success should be characterized in terms of suitability to a function or purpose. After that, I'll look at potential worries about the Carnapian distinction—including, e.g., the concern that it relies on the analytic/synthetic distinction. Finally, I will propose a somewhat modified and expanded version of the distinction and examine its consequences for the thesis that philosophy aims at discovering truths about phenomena of philosophical interest.

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.

Dilemma situations involving the choice of which human life to save in the case of unavoidable accidents are expected to arise only rarely in the context of autonomous vehicles. Nonetheless, the scientific community has devoted significant attention to finding appropriate and acceptable automated decisions in the event that AVs or drivers of AVs were indeed to face such situations. Awad and colleagues, in their now famous paper “The Moral Machine Experiment”, used a “multilingual online ‘serious game’ for collecting large-scale data (...) on how citizens would want AVs to solve moral dilemmas in the context of unavoidable accidents.” Awad and colleagues undoubtedly collected an impressive and philosophically useful data set of armchair intuitions. However, we argue that applying their findings to the development of “global, socially acceptable principles for machine learning” would violate basic tenets of human rights law and fundamental principles of human dignity. To make its arguments, our paper cites principles of tort law, relevant case law, provisions from the Universal Declaration of Human Rights, and rules from the German Ethics Code for Autonomous and Connected Driving.

Academics across widely ranging disciplines all pursue knowledge, but they do so using vastly different methods. Do these academics therefore also have different ideas about when someone possesses knowledge? Recent experimental findings suggest that intuitions about when individuals have knowledge may vary across groups; in particular, the concept of knowledge espoused by the discipline of philosophy may not align with the concept held by laypeople. Across two studies, we investigate the concept of knowledge held by academics across seven disciplines (N (...) = 1,581) and compare these judgments to those of philosophers (N = 204) and laypeople (N = 336). We find that academics and laypeople share a similar concept of knowledge, while philosophers have a substantially different concept. These experiments show that (a) in contrast to philosophers, other academics and laypeople attribute knowledge to others in some “Gettier” situations; (b) academics and laypeople are much less likely to attribute knowledge when reminded of the possibility of error, but philosophers are not affected by this reminder; and (c) non‐philosophy academics are overall more skeptical about knowledge than laypeople or philosophers. These findings suggest that academics across a wide range of disciplines share a similar concept of knowledge, and that this concept aligns closely with the intuitions held by laypeople, and differs considerably from the concept of knowledge described in the philosophical literature, as well as the epistemic intuitions of philosophers themselves.

In their widely cited article, Swain et al. report data that, purportedly, demonstrates instability of folk epistemic intuitions regarding the famous Truetemp case authored by Keith Lehrer. What they found is a typical example of priming, where presenting one stimulus before presenting another stimulus affects the way the latter is perceived or evaluated. In their experiment, laypersons were less likely to attribute knowledge in the Truetemp case when they first read a scenario describing a clear case of knowledge, and more (...) likely to ascribe knowledge when they first read a vignette describing a clear case of nonknowledge. We tried to replicate Swain et al. findings in three experiments: one devised in Polish, and the other two conducted in English. We found no priming effect for knowledge ratings regarding the Truetemp case – laypersons were similarly likely to attribute knowledge in all three investigated conditions. These three failed replication attempts are not decisive as to whether the priming effect in question occurs, nevertheless, the collected data puts Swain et al. conclusions about instability of epistemic intuitions in jeopardy.

Radical skepticism is the view that we know nothing, or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an interaction between two (...) factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e. that something is not the case) than when it’s positive (i.e. that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

Experimental philosophy, at least in its ‘negative’ variety, has standardly been portrayed as presenting a dramatic challenge to traditional philosophical methodology. As such, it has prompted a large variety of counter-arguments and defenses of intuition. In this paper, I argue that many of these objections to experimental philosophy rest on various oversimplifications that both experimental philosophers and their opponents have made regarding intuitions and philosophical methodology. Once these oversimplifications are abandoned, I argue that the experimentalist critique of current philosophical methods (...) becomes somewhat less dramatic, but also much less open to objection.

One widely-endorsed argument in the experimental philosophy literature maintains that intuitive judgments are unreliable because they are influenced by the order in which thought experiments prompting those judgments are presented. Here, we explicitly state this argument from ordering effects and show that any plausible understanding of the argument leads to an untenable conclusion. First, we show that the normative principle is ambiguous. On one reading of the principle, the empirical observation is well-supported, but the normative principle is false. On the (...) other reading, the empirical observation has only weak support, and the normative principle, if correct, would impugn the reliability of deliberative reasoning, testimony, memory, and perception, since judgments in all these areas are sensitive to ordering in the relevant sense. We then reflect on what goes wrong with the argument. (shrink)

The field of experimental philosophy has received considerable attention, essentially for producing results that seem highly counter-intuitive and at the same time question some of the fundamental methods used in philosophy. A substantial part of this attention has focused on the role of intuitions in philosophical methodology. One of the major contributions of experimental philosophy on this topic has been concrete evidence in support of intuitional diversity; the idea that intuitions vary systematically depending on variables such as ethnicity, socioeconomic background, (...) or gender. Because of the important implications, these findings have been the subject of extensive debate. Despite the seeming significance of the findings and despite all the debates that the experimental philosophy movement has prompted, what has not been examined systematically is the reproducibility of the results. Instead, the reported findings have been simply accepted as established facts. We set out to replicate a wide range of experiments and surprisingly failed to reproduce many of the reported findings, some of which are from the most cited and attention grabbing papers of the field. We draw two conclusions from our findings. The first is that the instability of intuitions has been exaggerated by experimental philosophers. Intuitions appear to be more uniform across different demographic groups. The argument that intuitions need to be discarded because they depend on arbitrary factors such as ethnicity, socioeconomic background, or gender does not seem tenable anymore. The second conclusion is that experimental philosophy needs a better system to ensure the reproducibility of published findings. The current research-publication system of various empirical fields, especially those employing statistical methods, leads to an overproduction of false-positive findings in the published literature. Unless changes are made to the current research-publication system, this overproduction is likely to continue, in experimental philosophy as well as other disciplines. (shrink)

Skepticism about the epistemic value of intuition in theoretical and philosophical inquiry fueled by the empirical discovery of irrational bias (e.g., the order effect) in people's judgments has recently been challenged by research suggesting that people can introspectively track intuitional instability. The two studies reported here build upon this, the first by demonstrating that people are able to introspectively track instability that was experimentally induced by introducing conflicting expert opinion about certain cases, and the second by demonstrating that it was (...) the presence of instability?not merely the presence of conflicting information?that resulted in changes in the relevant attitudinal states (i.e., confidence and belief strength). The paper closes with the suggestion that perhaps the best explanation for these (and other) findings may be that intuitional instability is not actually ?intuitional.? (shrink)

: Psychological explanations of philosophical intuitions can help us assess their evidentiary value, and our warrant for accepting them. To explain and assess conceptual or classificatory intuitions about specific situations, some philosophers have suggested explanations which invoke heuristic rules proposed by cognitive psychologists. The present paper extends this approach of intuition assessment by heuristics-based explanation, in two ways: It motivates the proposal of a new heuristic, and shows that this metaphor heuristic helps explain important but neglected intuitions: general factual intuitions (...) which have been highly influential in the philosophies of mind and perception but neglected in on-going debates in the epistemology of philosophy. To do so, the paper integrates results from three philosophically pertinent but hitherto largely unconnected strands of psychological research: research on intuitive judgement, analogy and metaphor, and memory-based processing, respectively. The paper shows that the heuristics-based explanation thus obtained satisfies the key requirements cognitive psychologists impose on such explanations, that it can explain the philosophical intuitions targeted, and that this explanation supports normative assessment of the intuitions' evidentiary value: It reveals whether particular intuitions are due to proper exercise of cognitive competencies or constitute cognitive illusions.

-/- Policy regulations of ethically controversial genetic technologies should, on the one hand, be based on ethical principles. On the other hand, they should be socially acceptable to ensure implementation. In addition, they should align with ethical theory. Yet to date we lack a reliable and valid scale to measure the relevant ethical judgements in laypeople. We target this lacuna. -/- We developed a scale based on ethical principles to elicit lay judgments: the Genetic Technologies Questionnaire (GTQ). In two pilot (...) studies and a pre-registered main study, we validated the scale in a representative sample of the US population. -/- The final version of the scale contains 20 items but remains highly reliable even when reduced to five. It also predicts behaviour; for example, ethical judgments as measured by the GTQ predicted hypothetical donations and grocery shopping. In addition, the GTQ may be of interest to policymakers and ethicists because it reveals coherent and ethically justified judgments in laypeople. For instance, the GTQ indicates that ethical judgments are sensitive to possible benefits and harms (in line with utilitarian ethics), but also to ethical principles such as the value of consent-autonomy. -/- In conclusion, the GTQ can be recommended for research in both experimental psychology and applied ethics, as well as a tool for ethically and empirically informed policymaking.

Conceptual analysis as traditionally understood can be improved by allowing the use of a certain kind of empirical investigation. The conceptual analysis in which the kind of empirical investigation in question is used can be called “empirical conceptual analysis”. In the present inquiry, I provide a systematic exposition of empirical conceptual analysis, so understood, considering what exactly empirical conceptual analysis is, the different kinds of empirical conceptual analysis, and the main application of the method within philosophy. It can be defined (...) as a method that consists in drawing a conclusion about the semantic application conditions of a predicate on the basis of observation of the manifestations of semantic intuitions. The different kinds of empirical conceptual analysis are distinguished according to the way the manifestations of semantic intuitions are observed. The main application of the method is solving conceptual disputes – situations in which different competent speakers of a language disagree about the semantic application conditions of a predicate from that language, and their disagreement is caused by the fact that they have different semantic intuitions about that predicate.

Cílem článku je prozkoumat otázku po epistemickém statusu morálních intuic. Empirické výzkumy na poli morální psychologie ukazují, že intuice hojně využíváme při morálním hodnocení. Spoléháme se na ně však i jako morální filosofové při testování našich teorií – má-li některá normativní teorie proti-intuitivní důsledky, chápeme to jako její vadu a vice versa. V článku se snažím zodpovědět otázku, zda je taková praxe odvolávání se na morální intuice jako na evidenci ospravedlnitelná – je morální intuice spolehlivým epistemickým kanálem? Nejprve se budu (...) opírat o příbuznou debatu zaměřenou na epistemické intuice, představím tzv. restrikcionistickou výzvu a vysvětlím, z jakého důvodu se zaměřuji na morální intuice. V následující sekci předložím dle mého názoru nejsilnější linii útoku na epistemickou spolehlivost morálních intuic – argument z intuitivní nestability. Dříve jsme nevycházeli z úžasu nad zprávami o masivních rozdílech mezi námi Zápaďany a obyvateli exotických krajin, kterými nás ze svých terénních výzkumů zásobovali etnografové a antropologové. Dnes to jsou především morální psychologové a experimentální filosofové, kteří nás udivují ještě více odhalováním značné variability v intuicích – tentokrát však nejen mezi civilizovanými a domorodými lidmi, nýbrž i v srdci naší vlastní kultury. V další části tak předložím jednoduchou typologii intuitivní nestability a představím v současnosti již značně rozsáhlý soubor dat, který dokumentuje právě tuto neblahou vlastnost morálních intuic. Na jejich základě pak ve finální sekci dospěji k závěru, že morální intuice nejsou schopné dostát epistemickým nárokům, které klademe na jiné informační zdroje (např. smyslové vnímání), a jako takové nemohou sehrávat svou domnělou evidenční roli. V úplném závěru předložím předběžné poznámky týkající se možnosti využívat morálních intuic spíše jako zdroje motivace a za tím účelem navrhnu obrátit filosofickou praxi testování normativních teorií naruby.

As a strategy for exploring the relationship between understanding and knowledge, we consider whether epistemic luck – which is typically thought to undermine knowledge – undermines understanding. Questions about the etiology of understanding have also been at the heart of recent theoretical debates within epistemology. Kvanvig (2003) put forward the argument that there could be lucky understanding and produced an example that he deemed persuasive. Grimm (2006) responded with a case that, he argued, demonstrated that there could not be lucky (...) understanding. In this paper, we empirically examine how participants' patterns of understanding attributions line up with the predictions of Kvanvig and Grimm. We argue that the data challenge Kvanvig's position. People do not differentiate between knowing-why and understanding-why on the basis of proper etiology: attributions of knowledge and understanding involve comparable (and minimal) roles for epistemic luck. We thus posit that folk knowledge and understanding are etiologically symmetrical. (shrink)

This paper discusses an influential view of moral intuition, according to which moral intuition is a kind of intellectual perception. The core claim of this quasi-perceptualist theory is that intuitions are like perceptual experiences in presenting propositions as true. In this work, it is argued that quasi-perceptualism is explanatorily superfluous in the moral domain: there is no need to postulate a sui generis quasi-perceptual mental state to account for moral intuition since rival theories can explain the salient mental features of (...) moral intuition. The essay is structured into three main sections. In a first one, I introduce the quasi-perceptualist view of moral intuition. In the second, I show that ordinary accounts can explain the salient psychological features of moral intuition without referring to intellectual perceptions. Finally, in the third section, I discuss whether moral intuitions have presentational phenomenology like perceptual experiences. (shrink)
