Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational (...) limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance errors are a minor factor in the gap; computational limitations underlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Unexpected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate. Key Words: biases; descriptive models; heuristics; individual differences; normative models; rationality; reasoning. (shrink)

A central issue in epistemology concerns the connection between truth and justification. The burden of our paper is to explain this connection. Reliabilism, defended by Goldman, assumes that the connection is one of reliability. We argue that this assumption is too strong. We argue that foundational theories, such as those articulated by Pollock and Chisholm fail to elucidate the connection. We consider the potentiality of coherence theories to explain the truth connection by means of higher level convictions about probabilities, which (...) we call doxastic ascent, and defend such a theory. Our defense appeals to the work of Reid and contemporary cognitive psychology in order to account for the psychological reality of higher level evaluations. (shrink)

The best grounds for accepting contextualism concerning knowledge attributions are to be found in how knowledge-attributing (and knowledge-denying) sentences are used in ordinary, nonphilosophical talk: What ordinary speakers will count as “knowledge” in some non-philosophical contexts they will deny is such in others. Contextualists typically appeal to pairs of cases that forcefully display the variability in the epistemic standards that govern ordinary usage: A “low standards” case (henceforth, “LOW”) in which a speaker seems quite appropriately and truthfully to ascribe knowledge (...) to a subject will be paired with a “high standards” case (“HIGH”) in which another speaker in a quite different and more demanding context seems with equal propriety and truth to say that the same subject (or a similarly positioned subject) does not know. The contextualist argument based on such cases is driven by the premises that the positive attribution of knowledge in LOW is true, and that the denial of knowledge in HIGH is true. And where the contextualist has constructed HIGH and LOW wisely, those premises are in turn powerfully supported by the two mutually reinforcing strands of evidence that both of the claims intuitively seem true, and that both claims are perfectly appropriate. The resulting argument for contextualism is very powerful indeed, but I am on the offensive making that case in another paper: “The Ordinary Language Basis for Contextualism and the New Invariantism.”.

Atomism denies that complexes exist. Common-sense metaphysics may posit masses, composite individuals and sets, but atomism says there are only simples. In a singularist logic, it is difficult to make a plausible case for atomism. But we should accept plural logic, and then atomism can paraphrase away apparent reference to complexes. The paraphrases require unfamiliar plural universals, but these are of independent interest; for example, we can identify numbers and sets with plural universals. The atomist paraphrases would fail if plurals (...) presuppose complexes: but an Appendix shows that reference to complexes is not required in the semantics of plurals. (shrink)

Academic dishonesty among students is not confined to the dynamics of the classrooms in which it occurs. The institution has a major role in fostering academic integrity. Ways that institutions can have a significant impact on attitudes toward and knowledge about academic integrity as well as reducing the incidence of academic dishonesty are described. These include the content of an effective academic honesty policy, campus-wide programs designed to foster integrity, and the development of a campus-wide ethos that encourages integrity.

Deepfakes pose a multi-faceted threat to the acquisition of knowledge. It is widely hoped that technological solutions—in the form of artificially intelligent systems for detecting deepfakes—will help to address this threat. I argue that the prospects for purely technological solutions to the problem of deepfakes are dim. Especially given the evolving nature of the threat, technological solutions cannot be expected to prevent deception at the hands of deepfakes, or to preserve the authority of video footage. Moreover, the success of such (...) technologies depends on institutional trust that is in short supply. Finally, outsourcing the discrimination between the real and the fake to automated, largely opaque systems runs the risk of undermining epistemic autonomy. (shrink)

This piece replies to commentators on my target article in this issue, 'Illusionism as a Theory of Consciousness', building on the arguments offered there. It groups commentators together by their attitude to illusionism, classifying them as advocates, explorers, sceptics, and opponents. It expands on the case for illusionism, refines the position, and responds to objections.

This paper has two aims. The first is to use contemporary discussions of naïve realist theories of perception to offer an interpretation of Merleau-Ponty’s theory of perception. The second is to use consideration of Merleau-Ponty’s theory of perception to outline a distinctive version of a naïve realist theory of perception. In a Merleau-Pontian spirit, these two aims are inter-dependent.

Byrne (2005) assumes that counterfactual thinking requires a comparison of facts with an imagined alternative. In our view, however, this assumption is unnecessarily restrictive. We argue that individuals do not necessarily engage in counterfactual simulations exclusively to evaluate factual reality. Instead, comparative evaluation is often suspended in favor of experiencing the counterfactual simulation as if it were real.

First published in 1977, this is an applied economics text, in which the basic theory of any introductory economics couurse is applied to a whole range of UK macro- and micro-economic policy issues. The book is designed specifically for first and second year university students, with the aim of demonstrating the relevance of theory to policy, how theory can be applied to policy problems and, in the process, to improve their understanding of the theory itself.

It is widely accepted that there is a visual field, but the analogous notion of an auditory field is rejected by many philosophers on the grounds that the metaphysics or phenomenology of audition lack the necessary spatial or phenomenological structure. In this paper, I argue that many of the common objections to the existence of an auditory field are misguided and that, contrary to a tradition of philosophical scepticism about the spatiality of auditory experience, it is as richly spatial as (...) visual experience—and in some ways even more so. By carefully considering the spatiality and boundedness of audition, along with how sounds or their sources are experienced as occurring within the surrounding acoustic environment, we can gain a better understanding of (i) our auditory experience of space and (ii) the conditions for the existence of spatial sensory fields in general in a way that does not privilege vision over the other senses.

This article explores the pros and cons of teaching moral development and moral psychology theories and principles in media ethics courses. Five theorists are introduced: Kohlberg, Gilligan, Rest, Kierkegaard, and Perry. Debates over the descriptive-prescriptive nature of the models are discussed, and a number of suggestions about how to implement the models in the classroom are offered.

In this paper, we explore the role of syntactic representations in set theory. We highlight a common inferential scheme in set theory, which we call the Syntactic Representation Inferential Scheme, in which the set theorist infers information about a concept based on the way that concept can be represented syntactically. However, the actual syntactic representation is only indicated, not explicitly provided. We consider this phenomenon in relation to the derivation indicator position that asserts that the ordinary proofs given in mathematical (...) discourse indicate syntactic derivations in a formal logical system. In particular, we note that several of the arguments against the derivation indicator position would seem to imply that set theorists could gain no benefits from the syntactic representations of concepts indicated by their definitions, yet set theorists clearly do.

It is sometimes suggested that we can think “in” natural language. According to this “cognitive” conception of language, we have a linguistic mind, or level of mentality, which operates by manipulating representations of natural language sentences. This paper outlines two evolutionary questions that the cognitive conception must address and looks at some versions of it to see which provides the best answers to them. The most plausible version, I argue, is the view that the linguistic mind is a virtual system, (...) which arose when early humans learned to engage in private speech and to regulate it using metacognitive skills originally developed for use in public argumentation.

Over fifty years ago, Albert Hirschman argued that dissatisfied consumers could either voice complaint or exit when they were dissatisfied with goods or services. Loyal consumers would voice rather than exit. Hirschman argued that making exit easier from publicly provided services, such as health or education, would reduce voice, taking the richest and most articulate away and this would lead to the deterioration of public services. This book provides the first thorough empirical study of these ideas. Using a modified version (...) of Hirschman's account, examining private and collective voice, and viewing loyalty as a form of social investment, it is grounded on a dedicated five-year panel study of British citizens. Given government policies over the past decade or more which make exit easier from public providers, this is a timely publication for all those who care about the quality of government services.

The "War" in science is largely the discussion between those who believe that science is above criticism and those who do not. After the Science Wars is a collection of essays by leading philosophers and scientists, all attempting to bridge interdisciplinary gulfs in this discussion.

This article considers the obligations filmmakers have when presenting historical dramas. That the form is dramatic art, it is argued, does not relieve filmmakers of the ordinary obligation to present as accurately as possible what they claim is historical truth. The article explores how filmmakers can make such a claim, over what it extends, and the limits and scope of the obligation it entails.
