Epistemic contextualism is one of the most hotly debated topics in contemporary epistemology. Contextualists claim that ‘know’ is a context-sensitive verb associated with different evidential standards in different contexts. Contextualists motivate their view based on a set of behavioural claims. In this paper, I show that several of these behavioural claims are false. I also show that contextualist test cases suffer from a critical confound, which derives from people's tendency to defer to speakers’ statements about their own mental states. My (...) evidence consists in results from several behavioural experiments. I conclude that contextualism is an idle hypothesis and I propose some general methodological lessons. (shrink)

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

Orthodoxy in the contemporary debate on knowledge ascriptions holds that the truth‐value of knowledge ascriptions is purely a matter of truth‐relevant factors. One familiar challenge to orthodoxy comes from intuitive practical factor effects . But practical factor effects turn out to be hard to confirm in experimental studies, and where they have been confirmed, they may seem easy to explain away. We suggest a novel experimental paradigm to show that practical factor effects exist. It trades on the idea that people (...) retract knowledge attributions when practical factors shift. We also explain why the resulting data raise a serious challenge to orthodoxy. (shrink)

Pinillos’ Why We Doubt presents a powerful critique of such global skeptical assertions as “I don’t know I am not a brain-in-a-vat (biv)” by introducing a cognitive mechanism that is sensitive to error possibilities and a Bayesian rule of rationality that this mechanism is designed to approximate. This multifaceted argument offers a novel counter to global skepticism, contending that our basis for believing such premises is underminable. In this work, we engage with Pinillos’ adoption of Bayesianism, questioning whether the Bayesian (...) principle that he invokes truly does fail to generate the verdict that we don’t we aren’t biv s, contrary to what Pinillos asserts. Furthermore, we argue that Pinillos’ empirical argument is not empirical enough; we need a lot more empirical work if we are going to counter global skepticism and win over neutral bystanders.

Appeals to ordinary thought and talk are frequent in philosophy, perhaps nowhere more than in contemporary epistemology. When an epistemological theory implies serious error in “commonsense” or “folk” epistemology, it is counted as a cost of the view. Similarly, when an epistemological theory respects or vindicates deep patterns in commonsense epistemology, it is viewed as a benefit of the view. Philosophers typically rely on introspection and anecdotal social observation to support their characterizations of commonsense epistemology. But recent experimental research shows (...) that philosophers employing these methods often seriously mischaracterize commonsense. Based on these findings, I propose a fundamental change to standard practice in the field. Whether the fundamental goal of epistemology is descriptive or prescriptive, experimentation is an integral part of the project. (shrink)

How does experimental philosophy address philosophical questions and problems? That is: What projects does experimental philosophy pursue? What is their philosophical relevance? And what empirical methods do they employ? Answers to these questions will reveal how experimental philosophy can contribute to the longstanding ambition of placing philosophy on the ‘secure path of a science’, as Kant put it. We argue that experimental philosophy has introduced a new methodological perspective – a ‘meta-philosophical naturalism’ that addresses philosophical questions about a phenomenon by (...) empirically investigating how people think about this phenomenon. This chapter asks how this novel perspective can be successfully implemented: How can the empirical investigation of how people think about something address genuinely philosophical problems? And what methods – and, specifically, what methods beyond the questionnaire – can this investigation employ? We first review core projects of experimental philosophy and raise the question of their philosophical relevance. For ambitious answers, we turn to experimental philosophy’s most direct historical precursor, mid-20th century ordinary language philosophy, and discuss empirical implementations of two of its research programmes that use experimental methods from psycholinguistics and corpus methods from the digital humanities.

Salience-sensitivity is a form of anti-intellectualism that says the following: whether a true belief amounts to knowledge depends on which error-possibilities are salient to the believer. I will investigate whether salience-sensitivity can be motivated by appeal to bank case intuitions. I will suggest that so-called third-person bank cases threaten to sever the connection between bank case intuitions and salience-sensitivity. I will go on to argue that salience-sensitivists can overcome this worry if they appeal to egocentric bias, a general tendency to (...) project our own mental states onto others. I will then suggest that a similar strategy is unavailable to stakes-sensitivists, who hold that whether a true belief amounts to knowledge depends on what is at stake for the believer. Bank case intuitions motivate salience- but not stakes-sensitivity. (shrink)

Moderate pragmatic invariantism (MPI) is a proposal to explain why our intuitions about the truth-value of knowledge claims vary with stakes and salient error-possibilities. The basic idea is that this variation is due to a variation not in the propositions expressed (as epistemic contextualists would have it) but in the propositions conversationally implicated. I will argue that MPI is mistaken: I will distinguish two kinds of implicature, namely, additive and substitutional implicatures. I will then argue, first, that the proponent of (...) MPI cannot appeal to additive implicatures because they don’t affect truth-value intuitions in the required way. Second, I will argue that the proponent of MPI cannot appeal to substitutional implicatures either because, even though they may have the required effects on truth-value intuitions, they don’t feature in the relevant cases. It follows that MPI is mistaken because whether the proponent of MPI appeals to additive or substitutional implicatures, at least one of the claims that make up her view is false. Along the way, I will suggest principles about implicatures that should be relevant not only to MPI, but to pragmatic accounts of seemingly semantic intuitions in general. (shrink)

The mentioning of error-possibilities makes us less likely to ascribe knowledge. This paper offers a novel psychological account of this data. The account appeals to “subadditivity,” a well-known psychological tendency to judge possibilities as more likely when they are disjunctively described.

Epistemic contextualism is the theory that “knows” is a context sensitive expression. As a linguistic theory, epistemic contextualism is motivated by claims about the linguistic behavior of competent speakers. This chapter reviews evidence in experimental cognitive science for epistemic contextualism in linguistic behavior. This research demonstrates that although some observations that are consistent with epistemic contextualism can be confirmed in linguistic practices, these observations are also equally well explained both by psychological features that do not provide support for contextualism and (...) by rival theories that are inconsistent with contextualism. I conclude that the motivation for epistemic contextualism is underdetermined by existing experimental evidence, yielding little reason to accept it as an account of our actual linguistic practices.

Sackris and Beebe (2014) report the results of a series of studies that seem to show that there are cases in which many people are willing to attribute knowledge to a protagonist even when her belief is unjustified. These results provide some reason to conclude that the folk concept of knowledge does not treat justification as necessary for its deployment. In this paper, we report a series of results that can be seen as supporting this conclusion by going some way (...) towards ruling out an alternative account of Sackris and Beebe’s results—the possibility that the knowledge attributions that they witnessed largely stem from protagonist projection, a phenomenon in language use and interpretation in which the speaker uses words that the relevant protagonist might use to describe her own situation and the listener interprets the speaker accordingly. With that said, we do caution the reader against drawing the conclusion too strongly, on the basis of results like those reported here and by Sackris and Beebe. There are alternative possibilities regarding what drives the observed knowledge attributions in cases of unjustified true belief that must be ruled out before, on the basis of such results, we can conclude with much confidence that the folk concept of knowledge does not treat justification as necessary for its deployment.

Knowledge ascriptions depend on so-called non-traditional factors. For instance, we become less inclined to ascribe knowledge when it’s important to be right, or once we are reminded of possible sources of error. A number of potential explanations of this data have been proposed in the literature. They include revisionary semantic explanations based on epistemic contextualism and revisionary metaphysical explanations based on anti-intellectualism. Classical invariantists reject such revisionary proposals and hence face the challenge to provide an alternative account. The most prominent (...) strategy here appeals to Gricean pragmatics. This paper focuses on a slightly less prominent strategy, which is based on the idea that non-traditional factors affect knowledge ascriptions because they affect what the putative knower believes. I will call this strategy doxasticism. The full potential of doxasticism is rarely appreciated in the literature and numerous unwarranted concerns have been raised. The goal of this paper is to present the strongest form of doxasticism and then to point out the genuine limitations of this position. I also sketch a closely related, more promising account.

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.

A central theoretical motivation for epistemic contextualism is that it can explain something that invariantism cannot. Specifically, contextualism claims that judgments about “knowledge” are sensitive to the salience of error possibilities and that this is explained by the fact that salience shifts the evidential standard required to truthfully say someone “knows” something when those possibilities are made salient. This paper presents evidence that undermines this theoretical motivation for epistemic contextualism. Specifically, it demonstrates that while error salience does sometimes impact “knowledge” (...) judgments as contextualism predicts, it does so in ways that are consistent with invariantism and does not require positing any additional contextualist semantics to explain. These results advance our understanding of the pathways by which error possibility affects “knowledge” judgments, answer a major challenge to invariantism, and suggest several methodological improvements for the study of knowledge attribution.

In this entry, we provide an overview of some of the methodological debates surrounding contextualism and consider whether they are, in effect, based on an underlying methodological dispute. We consider three modes of motivation of epistemic contextualism including i) the method of cases, ii) the appeal to linguistic analogies and iii) the appeal to conceptual analogies and functional roles. We also consider the methodological debates about contextualism arising from experimental philosophy. We conclude that i) there is no distinctive methodological doctrine (...) or set of methodological doctrines that is centrally invoked by all epistemic contextualists and ii) the substantive dispute about the truth of contextualism very frequently, although not invariably, reflects an underlying methodological dispute.

Changes in conversationally salient error possibilities, and/or changes in stakes, appear to generate shifts in our judgments regarding the correct application of ‘know’. One prominent response to these shifts is to argue that they arise due to shifts in belief and do not pose a problem for traditional semantic or metaphysical accounts of knowledge. Such doxastic proposals face familiar difficulties with cases where knowledge is ascribed to subjects in different practical or conversational situations from the speaker. Jennifer Nagel has recently (...) offered an ingenious response to these problematic cases—appeal to egocentric bias. Appeal to this kind of bias also has the potential for interesting application in other philosophical arenas, including discussions of epistemic modals. In this paper, I draw on relevant empirical literature to clarify the nature of egocentric bias as it manifests in children and adults, and argue that appeal to egocentric bias is ill-suited to respond to the problem cases for doxastic accounts. Our discussion also has significant impact on the prospects for application of egocentric bias in other arenas. (shrink)

Since Austin’s introduction of the locutionary-illocutionary-perlocutionary distinction, it has been a matter of debate within speech act theory whether illocutionary acts like promising, warning, refusing and telling require audience ‘uptake’ in order to be performed. Philosophers on different sides of this debate have tried to support their positions by appealing to hypothetical scenarios, designed to elicit intuitive judgements about the role of uptake. However, philosophers’ intuitions appeared to remain deadlocked, while laypeople’s intuitions have not yet been probed. To begin rectifying (...) that, we ran two experiments probing lay intuitions about the implications of uptake failure. Overall, we found that participants’ responses were skewed towards agreement that speech acts were performed, despite the lack of uptake. There were, however, significant differences across the four different speech act types we investigated (with the highest levels of agreement found for refusing, followed by warning, then telling, and finally promising). We also obtained evidence of complex effects relating to the (high or low) stakes involved in the scenarios. While this study only represents an initial exploration of intuitions about uptake, our results form a basis for further research into their nature and significance, across a range of speech acts, scenarios, and experimental designs.
