In this paper, we report the results of three high-powered replication studies in experimental philosophy, which bear on an alleged instability of folk philosophical intuitions: the purported susceptibility of epistemic intuitions about the Truetemp case (Lehrer, Theory of knowledge. Westview Press, Boulder, 1990) to order effects. Evidence for this susceptibility was first reported by Swain et al. (Philos Phenomenol Res 76(1):138–155, 2008); further evidence was then found in two studies by Wright (Cognition 115(3):491–503, 2010) and Weinberg et al. (Monist (...) 95(2):200–222, 2012). These empirical results have been quite influential in the recent metaphilosophical debate about the method of cases. However, none of Swain et al.’s ( 2008 ) predictions concerning order effects with Truetemp cases could be consistently and robustly replicated in our three experiments, and it is thus at best unclear whether Truetemp intuitions are in fact unstable. So, if proponents of the negative program in experimental philosophy still want to use order effects to challenge the reliability of philosophical case judgments, they would be well advised to look elsewhere instead. In any case, given the more robust empirical evidence that we present in this paper, the metaphilosophical flurry created by Swain et al. ( 2008 ) and Wright’s ( 2010 ) influential studies looks like mere alarmism in hindsight. (shrink)

According to the thought experiment most commonly used to argue against reliabilism, Mr. Truetemp is given an unusual but reliable cognitive faculty. Since he is unaware of the existence of this faculty, its deliverances strike him as rather odd. Many think that Truetemp would not have justified beliefs. Since he satisfies the reliabilist conditions for justified belief, reliabilism appears to be mistaken. I argue that the Truetemp case is underdescribed and that this leads readers to make erroneous (...) assumptions about Truetemp's epistemic situation. After examining empirical studies of actual subjects who, like Truetemp, have received new perceptual faculties, I show that Truetemp must have been endowed with all of the reorganized neural circuitry and cognitive skills that subjects with new perceptual faculties normally acquire during a long and difficult process of adaptation and development. When readers realize how much more the designers of Truetemp's new faculty had to do than simply slip an artificial device under Truetemp's scalp, I find that they no longer think his beliefs would be unjustified. Because the thought experiment fails to support anti-reliabilist intuitions when further details of the case are made explicit, the Truetemp thought experiment does not constitute a clear and decisive counterexample to reliabilism.

Keith Lehrer described the case of Mr Truetemp, who has reliably formed true beliefs about the temperature. The beliefs are produced by the action of a device (a "tempucomp" ) which has been surgically implanted in Truetemp's skull without his knowledge. The case is designed as a counterexample to process reliabilism. This short paper explores the question whether virtue epistemology is able to deal with the Truetemp case. It is argued that virtue-theoretic considerations lead to the rejection (...) of the Truetemp case as a case of warranted belief or knowledge, which suggests that virtue epistemology has the resources to handle the case. -/- .

The cases of Norman the Clairvoyant and Mr. Truetemp form classic counterexamples to the process reliabilist's claim that reliability is sufficient for prima facie justification. I discuss several ways in which contemporary reliabilists have tried to deal with these counterexamples, and argue that they are all unsuccessful. Instead, I propose that the most promising route lies with an appeal to a specific kind of higher-order defeat that is best cashed out in terms of properly functioning monitoring mechanisms.

A growing body of empirical literature challenges philosophers’ reliance on intuitions as evidence based on the fact that intuitions vary according to factors such as cultural and educational background, and socio-economic status. Our research extends this challenge, investigating Lehrer’s appeal to the Truetemp Case as evidence against reliabilism. We found that intuitions in response to this case vary according to whether, and which, other thought experiments are considered first. Our results show that compared to subjects who receive the (...) class='Hi'>Truetemp Case first, subjects first presented with a clear case of knowledge are less willing to attribute knowledge in the Truetemp Case, and subjects first presented with a clear case of nonknowledge are more willing to attribute knowledge in the Truetemp Case. We contend that this instability undermines the supposed evidential status of these intuitions, such that philosophers who deal in intuitions can no longer rest comfortably in their armchairs.

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.

In recent years, a growing body of experimental literature has called into question the reliability of our intuitions about hypothetical cases, and thereby called into question the use of intuitions in philosophy. In this paper, I critically assess one prominent example of this challenge, namely, Swain, Alexander, and Weinberg’s recent study of order effects on the Truetemp intuition. I argue that the very data that Swain,Alexander, and Weinberg find do not undermine, but instead support, the reliability of intuition. I (...) also show how intuition can itself be marshaled in the service of figuring out just when we can and cannot expect to find order effects on our intuitions. (shrink)

In this paper, we defend the claim that reflective knowledge is necessary for extended knowledge. We begin by examining a recent account of extended knowledge provided by Palermos and Pritchard (2013). We note a weakness with that account and a challenge facing theorists of extended knowledge. The challenge that we identify is to articulate the extended cognition condition necessary for extended knowledge in such a way as to avoid counterexample from the revamped Careless Math Student and Truetemp cases. We (...) consider but reject Pritchard’s (2012b) epistemological disjunctivism as providing a model for doing so. Instead, we set out an account of reflection informed by Confucianism and dual-process theory. We make the case that reflective knowledge offers a way of overcoming the challenge identified. We show why such knowledge is necessary for extended knowledge, while building on Sosa’s (2012) account of meta-competence. (shrink)

This chapter examines the best‐known intuitive counterexamples that have been pressed against Alvin Goldman's reliabilist theory of knowledge, and argues that something is wrong with them. It discusses the possibility that these intuitions might accord equally well with a more extreme externalist view, Williamson's “knowledge‐first” approach. Reliabilism has been examined largely in contrast to internalism, but its strengths and weaknesses arguably come into sharper focus if compare it with more radical forms of externalism as well. Goldman grants to the internalists (...) that Amanda and Mr. Truetemp are actually reliable in their belief formation, albeit reliable in a confusingly unfamiliar way. The chapter examines the consequences of taking the subject's acceptance as a causally necessary part of the formation of the beliefs one are supposed to evaluate. It argues that there is something strangely off‐target in BonJour's attempts to use a hypothetical process of acceptance as a diagnostic of the justification of unreflectively formed beliefs.

A popular counterexample directed against externalist epistemological views is that of an agent (Lehrer's "Truetemp" for example) whose beliefs are clearly neither justified nor known but that were generated in the manner that the externalist requires, thereby demonstrating externalism to be insufficient. In this essay I develop and defend an externalist account of knowledge – essentially an elaboration of Fred Dreske's information-theoretic account – that is not susceptible to those criticisms. I then briefly discuss the relationship between knowledge and (...) justification. (shrink)

Adam Carter (2022) recently proposed that a successful analysis of knowledge needs to include an autonomy condition. Autonomy, for Carter, requires a lack of a compulsion history. A compulsion history bypasses one’s cognitive competences and results in a belief that is difficult to shed. I argue that Carter’s autonomy condition does not cover partially autonomous beliefs properly. Some belief-forming processes are partially bypassing one’s competences, but not bypassing them completely. I provide a case for partially autonomous belief based on processing (...) fluency effects and argue that partially autonomous beliefs only amount to knowledge in some cases. I finally suggest how to adjust the autonomy condition to capture partially autonomous belief properly. (shrink)
