Theories of content purport to explain, among other things, in virtue of what beliefs have the truth conditions they do have. The desire for such a theory has many sources, but prominent among them are two puzzling facts that are notoriously difficult to explain: beliefs can be false, and there are normative constraints on the formation of beliefs.2 If we knew in virtue of what beliefs had truth conditions, we would be better positioned to explain how it is possible for (...) an agent to believe that which is not the case. Moreover, we do not say merely of such an agent that he believes that p when p is not the case. We say the agent made a mistake, and often criticize him accordingly; we think agents ought not have false beliefs, and that such beliefs should be changed; etc. An adequate theory of content would, presumably, reveal the source of these normative facts about the mental lives of agents. Indeed, it is typically taken to be an adequacy constraint on a theory of content that it help explain the possibility of error and the "normativity" of content. Teleological theories of content promise to do just this. (shrink)

Formal models of appearance and reality have proved fruitful for investigating structural properties of perceptual knowledge. This paper applies the same approach to epistemic justification. Our central goal is to give a simple account of The Preface, in which justified belief fails to agglomerate. Following recent work by a number of authors, we understand knowledge in terms of normality. An agent knows p iff p is true throughout all relevant normal worlds. To model The Preface, we appeal to the normality (...) of error. Sometimes, it is more normal for reality and appearance to diverge than to match. We show that this simple idea has dramatic consequences for the theory of knowledge and justification. Among other things, we argue that a proper treatment of The Preface requires a departure from the internalist idea that epistemic justification supervenes on the appearances and the widespread idea that one knows most when free from error.

The inflation of Type I error rates is thought to be one of the causes of the replication crisis. Questionable research practices such as p-hacking are thought to inflate Type I error rates above their nominal level, leading to unexpectedly high levels of false positives in the literature and, consequently, unexpectedly low replication rates. In this article, I offer an alternative view. I argue that questionable and other research practices do not usually inflate relevant Type I error (...) rates. I begin by introducing the concept of Type I error rates and distinguishing between statistical errors and theoretical errors. I then illustrate my argument with respect to model misspecification, multiple testing, selective inference, forking paths, exploratory analyses, p-hacking, optional stopping, double dipping, and HARKing. In each case, I demonstrate that relevant Type I error rates are not usually inflated above their nominal level, and in the rare cases that they are, the inflation is easily identified and resolved. I conclude that the replication crisis may be explained, at least in part, by researchers’ misinterpretation of statistical errors and their underestimation of theoretical errors. (shrink)

This paper argues that epistemic errors rooted in group- or identity- based biases, especially those pertaining to disability, are undertheorized in the literature on medical error. After sketching dominant taxonomies of medical error, we turn to the field of social epistemology to understand the role that epistemic schemas play in contributing to medical errors that disproportionately affect patients from marginalized social groups. We examine the effects of this unequal distribution through a detailed case study of ableism. There are (...) four primary mechanisms through which the epistemic schema of ableism distorts communication between nondisabled physicians and disabled patients: testimonial injustice, epistemic overconfidence, epistemic erasure, and epistemic derailing. Measures against epistemic injustices in general and against schema-based medical errors in particular are ultimately issues of justice that must be better addressed at all levels of health care practice.

During multiple testing, researchers often adjust their alpha level to control the familywise error rate for a statistical inference about a joint union alternative hypothesis (e.g., “H1,1 or H1,2”). However, in some cases, they do not make this inference. Instead, they make separate inferences about each of the individual hypotheses that comprise the joint hypothesis (e.g., H1,1 and H1,2). For example, a researcher might use a Bonferroni correction to adjust their alpha level from the conventional level of 0.050 to (...) 0.025 when testing H1,1 and H1,2, find a significant result for H1,1 (p < 0.025) and not for H1,2 (p > .0.025), and so claim support for H1,1 and not for H1,2. However, these separate individual inferences do not require an alpha adjustment. Only a statistical inference about the union alternative hypothesis “H1,1 or H1,2” requires an alpha adjustment because it is based on “at least one” significant result among the two tests, and so it refers to the familywise error rate. Hence, an inconsistent correction occurs when a researcher corrects their alpha level during multiple testing but does not make an inference about a union alternative hypothesis. In the present article, I discuss this inconsistent correction problem, including its reduction in statistical power for tests of individual hypotheses and its potential causes vis-à-vis error rate confusions and the alpha adjustment ritual. I also provide three illustrations of inconsistent corrections from recent psychology studies. I conclude that inconsistent corrections represent a symptom of statisticism, and I call for a more nuanced inference-based approach to multiple testing corrections. (shrink)

David Miller is the foremost exponent of the purist critical rationalist doctrine and here presents his mature views, discussing the role that logic and argument play in the growth of knowledge, criticizing the common understanding of argument as an instrument of justification, persuasion or discovery and instead advocating the critical rationalist view that only criticism matters. Miller patiently and thoroughly undoes the damage done by those writers who attack critical rationalism by invoking the sterile mythology of induction and justification that (...) it seeks to sweep away. In addition his new material on the debate on verisimilitude is essential reading for all working in this field. (shrink)

Using both quantitative and qualitative approaches, this study investigated the preference of learners of English as a foreign language for four types of written corrective feedback, which are often discussed in the literature, on grammatical, lexical, orthographic, and pragmatic errors. In particular, it concerned whether such preference is influenced by two learner variables, namely, foreign language enjoyment and proficiency level. The preference for selective vs. comprehensive WCF was also examined. The participants in the study were 117 University students in a (...) Thai EFL context. Analysis of questionnaire data revealed a tendency for learners to prefer more explicit types of WCF for most error types, irrespective of their proficiency and FLE level. High proficiency level learners rated less explicit WCF types as useful to some degree, whereas their low proficiency level counterparts did not. Similar results were found for the two FLE groups. Besides, the FLE level seemed to play a role in perceiving the value of WCF in terms of scope. The results of follow-up interviews showed that the linguistic features of learners' first language, existing knowledge of the target language, affective feelings, and teacher's role were the main factors contributing to variation in learners' preferences. Possible pedagogical implications are discussed. (shrink)

I discuss an aspect of the relation between accounts of de se thought and the phenomenon of immunity to error through misidentification. I will argue that a deflationary account of the latter—the Simple Account, due to Evans —will not do; a more robust one based on an account of de se thoughts is required. I will then sketch such an alternative account, based on a more general view on singular thoughts, and show how it can deal with the problems (...) I raise for the Simple Account. (shrink)

In a recent paper, Jakob Hohwy argues that the emerging predictive processing perspective on cognition requires us to explain cognitive functioning in purely internalistic and neurocentric terms. The purpose of the present paper is to challenge the view that PP entails a wholesale rejection of positions that are interested in the embodied, embedded, extended, or enactive dimensions of cognitive processes. I will argue that Hohwy’s argument from analogy, which forces an evidentiary boundary into the picture, lacks the argumentative resources to (...) make a convincing case for the conceptual necessity to interpret PP in solely internalistic terms. For this reason, I will reconsider the postulation and explanatory role of the evidentiary boundary. I will arrive at an account of prediction error minimization and its foundation on the free energy principle that is fully consistent with approaches to cognition that emphasize the embodied and interactive properties of cognitive processes. This gives rise to the suggestion that explanatory pluralism about the application of PP is to be preferred over Hohwy’s explanatory monism that follows from his internalistic and neurocentric view of predictive cognitive systems.

On a common view of scenario-based sceptical arguments sceptical scenarios are error-possibilities, i.e. their point is to introduce the possibility of having only false beliefs. However, global error is impossible for purely logical/conceptual reasons: Even if one’s beliefs are consistent, the negations of one’s beliefs need not be consistent as well. My paper deals with the question of what the consequences of this result are. Two attempts at repairing scenario-based sceptical arguments within the framework of understanding sceptical scenarios (...) as error-possibilities are found wanting. Instead, what should be given up is the assumption that sceptical scenarios are error-possibilities. What is thought-provoking about the scenario of the brain in a vat is not that none of its empirical beliefs are true, but that all of its empirical beliefs fall short of knowledge at the same time. Hence, sceptical scenarios are not error-possibilities, but ignorance possibilities. If this is so, both the closure argument and the underdetermination argument commit a subtle mistake and should be replaced by slightly different arguments. The principle of excluded ignorance-possibilities turns out to be an epistemological principle that is faithful to scepticism’s tenets without misinterpreting sceptical scenarios as error-possibilities.

In the 1950s–60s biochemists searched intensively for a series of high-energy molecules in the cell. Although we now believe that these molecules do not exist, biochemists claimed to have isolated or identified them on at least sixteen occasions. The episode parallels the familiar eighteenth-century case of phlogiston, in illustrating how error is not simply the loss of facts but, instead, must be actively constructed. In addition, the debates surrounding each case demonstrate how revolutionary-scale disagreement is sometimes resolved by differentiating (...) or partitioning empirical domains, rather than by replacement of one theory by another.

An influential argument in bioethics involves appeal to disgust, calling on us to take it seriously as a moral guide (e.g. Kass, Miller, Kahan). Some argue, for example, that genetic enhancement, especially via human reproductive cloning, is repellant or grotesque. While objectors have argued that repugnance is morally irrelevant (e.g. Nussbaum, Kelly), I argue that the problem is more fundamental: it is psychologically irrelevant. Examining recent empirical data suggests that disgust’s influence on moral judgment may be like fatigue: an exogenous (...) influence, yielding a “performance error” that does not reflect our understanding of moral matters. This conclusion also challenges appeals to repugnance on other topics (such as homosexuality) and generally downplays the importance of disgust in moral discourse. (shrink)

I argue that the Bayesian Way of reconstructing Duhem's problem fails to advance a solution to the problem of which of a group of hypotheses ought to be rejected or "blamed" when experiment disagrees with prediction. But scientists do regularly tackle and often enough solve Duhemian problems. When they do, they employ a logic and methodology which may be called error statistics. I discuss the key properties of this approach which enable it to split off the task of testing (...) auxiliary hypotheses from that of appraising a primary hypothesis. By discriminating patterns of error, this approach can at least block, if not also severely test, attempted explanations of an anomaly. I illustrate how this approach directs progress with Duhemian problems and explains how scientists actually grapple with them. (shrink)

We argued that formal objections to the error theory overgeneralize and therefore fail. Christine Tiefensee and Gregory Wheeler deny this. We argue that they are wrong, for two reasons. The first concerns how we should adjudicate conflicts between formal and substantive commitments. The second concerns an overlooked tension between formal objections and non-error-theoretic views. Our discussion shows that the commitments behind formal objections to the error theory, such as the dual schema, should be regarded as much more (...) contentious than is often assumed. (shrink)

Jonas Olson writes that "a plausible moral error theory must be an error theory about all irreducible normativity". I agree. But unlike Olson, I think we cannot believe this error theory. I first argue that Olson should say that reasons for belief are irreducibly normative. I then argue that if reasons for belief are irreducibly normative, we cannot believe an error theory about all irreducible normativity. I then explain why I think Olson's objections to this argument (...) fail. I end by showing that Olson cannot defend his view as a partly revisionary alternative to an error theory about all irreducible normativity. (shrink)

I here defend the thesis that the best life is the life that one plays as a game—specifically, a ‘Suitsian’ game that meets the definition proposed in The Grasshopper by Bernard Suits. Even more specifically, it is a nested, open, role-playing game where the life’s quality as a game partly depends on there being no more people than players. To defend this thesis I refute two powerful challenges to it, one from Thomas Hurka (2006) and another from within The Grasshopper (...) itself. In the process, I offer a new interpretation of that enigmatic and challenging book. (shrink)

Ginger Schultheis offers a novel and interesting argument against epistemic permissivism. While we think that her argument is ultimately uncompelling, we think its faults are instructive. We explore the relationship between epistemic permissivism, Margin-for-Error principles, and an epistemological version of Dominance reasoning.

Modal intuitions are not only the primary source of modal knowledge but also the primary source of modal error. An explanation of how modal error arises — and, in particular, how erroneous modal intuitions arise — is an essential part of a comprehensive theory of knowledge and evidence. This chapter begins with a summary of certain preliminaries: the phenomenology of intuitions, their fallibility, the nature of concept-understanding and its relationship to the reliability of intuitions, and so forth. It (...) then identifies two sources of modal error: the first has to do with the failure to distinguish between metaphysical possibility and various kinds of epistemic possibility; the second, with the local misunderstanding of one's concepts. The first source of error is widely misunderstood; the second source has not been discussed in philosophical literature. This source of modal error, and the potential to overcome it, has wide-ranging implications for philosophical method. The failure to understand these sources of modal error has recently led to sceptical accounts of intuition and modal error, which are, ultimately self-defeating. (shrink)

Aristotle sometimes claims that the perception of special perceptibles by their proper sense is unerring. This claim is striking, since it might seem that we quite often misperceive things like colours, sounds and smells. Aristotle also claims that the perception of common perceptibles is more prone to error than the perception of special perceptibles. This is puzzling in its own right, and also places constraints on the interpretation of. I argue that reading Alexander of Aphrodisias on perceptual error (...) can help to make good sense of both of Aristotle’s claims. (shrink)

If we consider certain features of Spinoza's metaphysics, it can seem very difficult to see how error, or the having of false ideas, is possible. In this paper I want to give the metaphysical background to the problem, before turning to a more detailed consideration of how Spinoza in fact accounts for error, or the having of false ideas. I will show the importance of the notions of adequacy and inadequacy in Spinoza's account. Having done this I will (...) return to the central problem of accounting for the ontological status of false ideas vis a vis both the Infinite Intellect, and finite minds. (shrink)

In this paper, I argue that genuine ethical deliberation, and hence ethical agency, is incompatible in principle with the possession of determinate practical prescriptions concerning how best to act in a concrete ethical situation. I make this argument principally by way of an analogy between gameplay and ethical deliberation. I argue that trivially solved games of perfect information (the example I use is tic‐tac‐toe) are, or become, in some sense unplayable for the individual for whom the game is trivially solved. (...) The reason for this, I suggest, is that there ceases to be space within the game for the distinction between that individual being a better and being a worse player of the game. I then use this example as an occasion to reflect on the kind of epistemic indeterminacy that appears to be a condition of genuine ethical deliberation. (shrink)

Coming from Hubert Dreyfus’ recent book ‘‘Retrieving Realism”, the paper presents embodied pre-conceptual perception and representational cognition as two contrasting perspectives on accessing the world. It further characterises the ‘different forms of knowledge emerging from these perspectives and how they dynamically relate to each other. Taking up the Peircean theory of signs and abductive reasoning as methods of discovery, computers are analysed as semiotic machines that formally model and objectify explicit knowledge about social practices and that can be embedded in (...) the sign processes of thereby restructured practices. This practice theoretical perspective allows for both, understanding the limits of AI and pointing to options for productively combining the performance of ‘‘cognitive artifacts” with the tacit skills of knowledge workers.

Quality assurance in large terminologies is a difficult issue. We present two algorithms that can help terminology developers and users to identify potential mistakes. We demon­strate the methodology by outlining the different types of mistakes that are found when the algorithms are applied to SNOMED-CT. On the basis of the results, we argue that both formal logical and linguistic tools should be used in the development and quality-assurance process of large terminologies.

Retractions solicited by authors following the discovery of an unintentional error—what we henceforth call a “self-retraction”—are a new phenomenon of growing importance, about which very little is known. Here we present results of a small qualitative study aimed at gaining preliminary insights about circumstances, motivations and beliefs that accompanied the experience of a self-retraction. We identified retraction notes that unambiguously reported an honest error and that had been published between the years 2010 and 2015. We limited our sample (...) to retractions with at least one co-author based in the Netherlands, Belgium, United Kingdom, Germany or a Scandinavian country, and we invited these authors to a semi-structured interview. Fourteen authors accepted our invitation. Contrary to our initial assumptions, most of our interviewees had not originally intended to retract their paper. They had contacted the journal to request a correction and the decision to retract had been made by journal editors. All interviewees reported that having to retract their own publication made them concerned for their scientific reputation and career, often causing considerable stress and anxiety. Interviewees also encountered difficulties in communicating with the journal and recalled other procedural issues that had unnecessarily slowed down the process of self-retraction. Intriguingly, however, all interviewees reported how, contrary to their own expectations, the self-retraction had brought no damage to their reputation and in some cases had actually improved it. We also examined the ethical motivations that interviewees ascribed, retrospectively, to their actions and found that such motivations included a combination of moral and prudential considerations. These preliminary results suggest that scientists would welcome innovations to facilitate the process of self-retraction. (shrink)

We report an empirical study of elementary algebra errors, conducted in three separate schools. The errors are diagnosed using mal‐rules, as proposed by Sleeman (1984, 1,985). Our analysis uncovers the following properties of algebra mal‐rules: The frequency of mal‐rules is severely skewed, there are many infrequent mal‐rules and few frequent ones; mal‐rules are very unstable, students typically use mal‐rules very irregularly; different mal‐rules have explanatory power in different schools (many of our most powerful mal‐rules are previously unreported); mal‐rule diagnosis Is (...) more successful with more skilled students; students' confidence ratings do not partition the total set of mal‐rules, every mal‐rule we find is associated with high confidence ratings by at least one student. The Implications of our data for cognitive theories of error generation are discussed. Contrary to commonplace assumptions, we argue that It is impossible to make a clear distinction between slips and mistakes; most errors depend on properties of the knowledge base and the cognitive architecture. Errors In a procedural skill cannot be assumed to be purely syntactic In orgin. (shrink)

Kant’s conception of the relation between knowledge and doubt stands opposed to much of contemporary epistemology. For Kant denies that it is possible for one to have knowledge of how things are without having a ground for one’s judgment that guarantees its truth. Knowledge, according to him, is judgment that is based on a ground that the judger recognizes to guarantee the truth of her judgment. A judgment that is based on such a ground, trivially, excludes any doubt the judger (...) might have had with respect to it. Therefore knowledge implies certainty. Much of contemporary epistemology has no room for the idea of a truth-guaranteeing ground. By contrast, Kant thinks that the rejection of the idea of a truth-guaranteeing ground has a devastating effect. It does not only render unintelligible the idea of knowledge, but, because of that, the very idea of a subject that is able to be ignorant about things, to have doubts about them or even to err about them. The paper defends the Kantian account of knowledge with the aim to show that ignorance, doubt and error can only characterize, and hence trouble, a subject that knows herself to have a capacity that enables her to overcome any possible doubt and error.

Next SectionThis article proposes that knowledge of cultural expectations concerning ethical responses to unintentional harm can help students and physicians better to understand patients’ distress when physicians fail to disclose, apologise for, and make amends for harmful medical errors. While not universal, the Judeo-Christian traditions of confession, repentance, and forgiveness inform the cultural expectations of many individuals within secular western societies. Physicians’ professional obligations concerning truth telling reflect these expectations and are inclusive of the disclosure of medical error, while (...) physicians may express a need for self-forgiveness after making errors and should be aware that patients may also rely upon forgiveness as a means of dealing with harm. The article recommends that learning how to disclose errors, apologise to injured patients, ensure that these patients’ needs are met, and confront the emotional dimensions of one’s own mistakes should be part of medical education and reinforced by the conduct of senior physicians.

We first deal with a few preliminary matters and discuss what-if any-distinct impact belief in moral error theory should have on our moral practice. Second, we describe what is involved in giving an answer to our leading question and take notice of some factors that are relevant to what an adequate answer might look like. We also argue that the specific details of adequate answers to our leading question will depend largely on context. Third, we consider three extant answers (...) to our leading question: fictionalism, conservationism, and abolitionism. Of these three, conservationism seems most promising. However, conservationism leaves pertinent questions unanswered. In order to provide answers to these questions, and ultimately to provide an answer to our leading question, conservationism needs to be supplemented, yielding an account we call “negotiationism.” This final proposal is not neat and tidy, but it might work reasonably well in the moral environment in which error theorists are likely to find themselves.

In a critique of my work on ‘taking the blame’ as a response to medical errors, my position on the potential goods of individual responsibility and blame is challenged. It is suggested that medicine is a ‘team sport’ and several rich examples are provided to support the possible harms of practitioner self-blame. Yet, it appears that my critics have misunderstood my demands and to whom they are directed. With this response, I offer several clarifications of my account, as well as (...) a reiteration on the role of self-blame after medical error. (shrink)
