In this paper I develop and present a unified account of information, misinformation, and disinformation and their interconnections. The unified account is rooted in Paul Grice’s notions of natural and non-natural meaning (in: Grice (ed) Studies in the way of words. Harvard University Press, Cambridge, pp 213–223, 1957) and a corresponding distinction between natural and non-natural information (Scarantino and Piccinini in Metaphilosophy 41(3):313–330, 2010). I argue that we can specify at least three specific kinds of non-natural information. Thus, as varieties (...) of non-natural information there is intentionally non-misleading information, unintentionally misleading information—i.e. misinformation—and intentionally misleading information—i.e. disinformation. By shifting the focus from the truth-values of content to the intention/intentionality and misleadingness/non-misleadingness of that content I obtain a unified account that makes room for the potential misleadingness of true content (true disinformation), the potential non-misleadingness of false content (irony), and everything in between.

The present paper argues that there is a knowledge norm for conversational implicature: one may conversationally implicate p only if one knows p. Linguistic data about the cancellation behavior of implicatures and the ways they are challenged and criticized by speakers is presented to support the thesis. The knowledge norm for implicature is then used to present a new consideration in favor of the KK thesis. It is argued that if implicature and assertion have knowledge norms, then assertion requires not (...) only knowledge but iterated knowledge: knowing that you know that you know that... you know. Such a condition on permissible assertion is argued to be plausible only if the KK thesis is true. (shrink)

Not every speech act can be a lie. A good definition of lying should be able to draw the right distinctions between speech acts that can be lies and speech acts that under no circumstances are lies. This paper shows that no extant account of lying is able to draw the required distinctions. It argues that a definition of lying based on the notion of ‘assertoric commitment’ can succeed where other accounts have failed. Assertoric commitment is analysed in terms of (...) two normative components: ‘accountability’ and ‘discursive responsibility’. The resulting definition of lying draws all the desired distinctions, providing an intensionally adequate analysis of the concept of lying. (shrink)

Lies are typically defined as believed falsehoods asserted with the intention of deceiving the hearer. A particularly problematic case for this definition is that of false implicatures. These are prototypically cases where the proposition expressed by the speaker's utterance is true, yet an implicature conveyed by this proposition in context is false. However, implicature is a diverse category and whether a blanket statement such as “false implicatures are lies,” as some have argued can account for all of them is open (...) to investigation. We present an experimental investigation of whether naïve participants define different types of implicatures as lies. Our results show that only a couple of types of implicatures were strongly rated as lies by participants. These results suggest that participants distinguish between different types of communicated meanings on linguistic grounds, contributing both to the literature on lying, as well as to theoretical discussions of how different types of meaning are communicated.

In the philosophical literature on the definition of lying, the analysis is generally restricted to cases of flat-out belief. This chapter considers the complex phenomenon of lies involving partial beliefs – beliefs ranging from mere uncertainty to absolute certainty. The first section analyses lies uttered while holding a graded belief in the falsity of the assertion, and presents a revised insincerity condition, requiring that the liar believes the assertion to be more likely to be false than true. The second section (...) analyses assertions that express graded beliefs, exploring how mitigation and reinforcement can alter the insincerity conditions for lying. The last section considers the case of lies that attack certainty (knowledge-lies), understood as attempt to alter the hearer's graded beliefs. (shrink)

In the philosophical debate on lying, there has generally been agreement that either the speaker believes that his statement is false, or he believes that his statement is true. This article challenges this assumption, and argues that lying is a scalar phenomenon that allows for a number of intermediate cases – the most obvious being cases of uncertainty. The first section shows that lying can involve beliefs about graded truth values (fuzzy lies) and graded beliefs (graded-belief lies). It puts forward (...) a new definition to deal with these scalar parameters, that requires that the speaker asserts what he believes more likely to be false than true. The second section shows that statements are scalar in the same way beliefs are, and accounts for a further element of scalarity, illocutionary force. (shrink)

This paper discusses the ethics of public health communication. We argue that a number of commonplace tools of public health communication risk qualifying as non-honest and question whether or not using such tools is ethically justified. First, we introduce the concept of honesty and suggest some reasons for thinking it is morally desirable. We then describe a number of common ways in which public health communication presents information about health-promoting interventions. These include the omission of information about the magnitude of (...) benefits people can expect from health-promoting interventions, and failure to report uncertainty associated with the outcomes of interventions. Next we outline some forms of behaviour which are generally recognised by philosophers as being non-honest, including deception, manipulation, and so on. Finally, we suggest that many of the public health communicative practices identified earlier share features with the non-honest behaviours described and suggest this warrants reflection upon whether such non-honesty is justified by the goals of public health communication.

Lying is an important moral phenomenon that most people are affected by on a daily basis—be it in personal relationships, in political debates, or in the form of fake news. Nevertheless, surprisingly little is known about what actually constitutes a lie. According to the traditional definition of lying, a person lies if they explicitly express something they believe to be false. Consequently, it is often assumed that people cannot lie by more indirectly communicating believed‐false claims, for instance by merely conversationally (...) implicating them. In this paper, we subject this claim to an empirical test. In a preregistered study of 300 participants, we investigate how people judge cases of implicit deceptions that would usually be excluded by the traditional definition of lying (i.e., conversational implicatures, presuppositions, and nonverbal actions). Our results show that people do in fact consider it possible to lie by indirect means, suggesting that people have a broader concept of lying than is usually assumed. Moreover, our findings indicate that lie judgments are closely tied to the extent to which agents are perceived as having committed themselves to the believed‐false claims they have communicated. We discuss the implications of our results for the traditional definition of lying and propose a new commitment‐based definition of lying that can account for the findings of our experiment.

This paper analyses the communicative and epistemic value of retweeting (and more generally of reposting content on social media). Against a naïve view, it argues that retweets are not acts of endorsement, motivating this diagnosis with linguistic data. Retweeting is instead modelled as a peculiar form of quotation, in which the reported content is indicated rather than reproduced. A relevance-theoretic account of the communicative import of retweeting is then developed, to spell out the complex mechanisms by which retweets achieve their (...) communicative goals. The last section outlines the epistemic threats posed by the increasing prevalence of retweeting on social media, linking them to the low reputational, cognitive and practical costs linked to this emerging form of communication.

This paper defends the simple view that in asserting that p, one lies iff one knows that p is false. Along the way it draws some morals about deception, knowledge, Gettier cases, belief, assertion, and the relationship between first- and higher-order norms.

This thesis addresses philosophical problems concerning improper assertions. The first part considers the issue of defining lying: here, against a standard view, I argue that a lie need not intend to deceive the hearer. I define lying as an insincere assertion, and then resort to speech act theory to develop a detailed account of what an assertion is, and what can make it insincere. Even a sincere assertion, however, can be improper (e.g., it can be false, or unwarranted): in the (...) second part of the thesis, I consider these kinds of impropriety. An influential hypothesis maintains that proper assertions must meet a precise epistemic standard, and several philosophers have tried to identify this standard. After reviewing some difficulties for this approach, I provide an innovative solution to some known puzzles concerning the permissibility of false assertions. In my view, assertions purport to aim at truth, but they are not subject to a norm that requires speakers to assert a proposition only if it is true. (shrink)

Survey of different definitions of lying and deceiving, with an emphasis on the contemporary debate between Thomas Carson, Roy Sorensen, Don Fallis, Jennifer Saul, Paul Faulkner, Jennifer Lackey, David Simpson, Andreas Stokke, Jorg Meibauer, Seana Shiffrin, and James Mahon, among others, over whether lies always aim to deceive. Related questions include whether lies must be assertions, whether lies always breach trust, whether it is possible to lie without using spoken or written language, whether lies must always be false, whether lies (...) that are unsuccessful are still lies, and whether deception must aim at creating false beliefs as opposed to preventing people from acquiring true beliefs.

The present study examines cross-cultural differences in people’s concept of lying with regard to the question of whether lying requires an agent to _say_ something they believe to be false. While prominent philosophical views maintain that lying entails that a person explicitly expresses a believed-false claim, recent research suggests that people’s concept of lying might also include certain kinds of deception that are communicated more indirectly. An important drawback of previous empirical work on this topic is that only few studies (...) have investigated people’s concept of lying in non-Western samples. In the present study, we compare people’s intuitions about lying with indirect deceptions (i.e., presuppositions, conversational implicatures, and non-verbal actions) in a sample of _N_ = 255 participants from Russia and _N_ = 300 participants from the United Kingdom. Our findings show a strong degree of similarity between lie ratings of participants from Russia and the United Kingdom, with both samples holding it possible for agents to lie with deceptive statements and actions that do not involve the agent _saying_ something they believe to be false.

According to the traditional definition of lying, somebody lies if he or she makes a believed-false statement with the intention to deceive. The traditional definition has recently been challenged by non-deceptionists who use bald-faced lies to underpin their view that the intention to deceive is no necessary condition for lying. We conducted two experiments to test whether their assertions are true. First, we presented one of five scenarios that consisted of three different kinds of lies. Then we asked participants to (...) judge whether the scenario at hand was a lie, whether the speaker intended to deceive somebody, and how they would judge the behavior in terms of morality. As expected, our results indicate that the intention to deceive is not a necessary condition for lying. Participants rated indifferent lies to be lies and judged that no intention to deceive was involved in these cases. In addition, all bald-faced lies were evaluated as lies. However, participants widely ascribed an intention to deceive to bald-faced lies, which thus might not apply as counterexamples against the traditional definition of lying. Besides, lies are judged as morally wrong regardless of an intention to deceive. (shrink)

Lying is a familiar and important concept for virtually all of us, and philosophers have written a lot about what it means to lie. Although it is commonly accepted that an adequate definition of lying captures people's use and understanding of this concept, there have been surprisingly few empirical studies on it. n recent years, however, there is a trend emerging to remedy this lacuna. In this paper, we provide an overview of these studies. Starting from a widely accepted philosophical (...) definition of lying, we focus on the following three questions: Is an intention to deceive required for lying? Is it possible to lie despite saying something true? Can you lie by falsely implicating? (shrink)

This paper presents a novel conceptualization of a type of untruthful speech that is of eminent political relevance but has hitherto been unrecognized: epistemically exploitative bullshit (EEB). Speakers engaging in EEB are bullshitting: they deceive their addressee regarding their unconcern for the very difference between truth and falsity. At the same time, they exploit their discursive victims: they oblige their counterparts to perform unacknowledged and emotionally draining epistemic work to educate the speakers about the addressees' oppression, only to discredit their (...) epistemic trustworthiness. I argue that EEB is irreducible to various recently discussed untruthful speech, and in particular to Frankfurtian bullshit, as well as to epistemic exploitation or other epistemic injustices. Taking inspiration from Sartre's analysis of anti-Semitic discourse, where bullshitting and epistemic exploitation are essentially interlinked, I instead suggest that recognizing the distinctiveness of EEB allows for a more refined conceptualization of these discursive phenomena. Specifically, I show how bad faith and the ensuing collective diffusion and delegation of epistemic responsibility play a so far neglected but key role here. I ultimately demonstrate that with Sartre's help, we can grasp how the existential, interpersonal and institutional dimensions involved in the negotiation of truth seamlessly intersect better than we would with the lens of analytic or critical epistemology alone.

Les explications de ce pourquoi mentir est mal sont toutes inadéquates. Leur problème commun se situe dans leur structure unitaire. Ces analyses présupposent que tous les mensonges sont mauvais pour la même raison unificatrice. Cette supposition ne rend cependant pas justice au phénomène du mensonge, et ce, parce qu’on peut s’objecter à l’acte de mentir de différentes façons. Ainsi je suggère qu’il faut un changement dialectique en direction d’un traitement pluraliste de ce qui est mauvais dans le mensonge. Il ne (...) faut pas forcer une unité sur la structure morale du mensonge lorsqu’il y a en fait pluralité. (shrink)

Lying is an everyday moral phenomenon about which philosophers have written a lot. Not only the moral status of lying has been intensively discussed but also what it means to lie in the first place. Perhaps the most important criterion for an adequate definition of lying is that it fits with people’s understanding and use of this concept. In this light, it comes as a surprise that researchers only recently started to empirically investigate the folk concept of lying. In this (...) paper, we describe three experimental studies which address the following questions: Does a statement need to be objectively false in order to constitute lying? Does lying necessarily include the intention to deceive? Can one lie by omitting relevant facts? (shrink)

In this essay, I advance an argument against the expansion and acceptance of postmodern metaphysical antirealist ideologies in the development of nursing theory in North America. I suggest mystical theoretical explanations of care, the rejection of empirical epistemology, and a return to divinity in nursing represent an intellectual dead end, as these ideas do little to help resolve real‐world health issues and also negate the need for the academic discrimination of bad ideas. I examine some of the philosophical foundations of (...) nursing theory and deconstruct some of the more preternatural theories that have become established as the dominant conventional wisdom in the academy. It is argued that this can be characterized as a form of self‐deception, and overall has had a negative impact on advancement of the nursing profession and public health care. Reasons behind the widespread acceptance of these irrational theoretical stances in nursing and the ongoing support for mystical therapeutic interventions are explored. (shrink)

To date, existing studies on paltering argue the thesis that paltering is never ethically justifiable; it is akin to deception, since one uses truthful statements with an intention to deceive. This study contends the above essential description and rather argues the thesis: it is a hasty generalisation to conclude that just because paltering has been employed in some fields such as the fields of negotiation and politics to deceive, it is therefore synonymous with deception. Specifically, I show in this study (...) that paltering does not necessarily imply deception, and is distinct from lying. And following a particular interpretation of a moral theory from the global South – ubuntu – paltering is a justified (as well as ethically acceptable) non-disclosure strategy when truthful disclosure would harm one’s relational capacity or jeopardise social cohesion. I am optimistic that this study makes a conceptual contribution to ethical literature on paltering, and introduces fresh perspective to the same by showing how an African moral theory may be used to evaluate paltering.
