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.

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)

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 paper aims to distil the essence of deception performed by means of withholding information, a topic hitherto largely neglected in the psychological, linguistic, and philosophical research on deception. First, the key conditions for deceptively withholding information are specified. Second, several notions related to deceptively withholding information are critically addressed with a view to teasing out the main forms of withholding information. Third, it is argued that deceptively withholding information can be conceptualized in pragmatic-philosophical terms as being based on the (...) violation of Grice's first maxim of Quantity, which is conducive to covertly untruthful meaning, specifically hearer-inferred what is said that presents the violation of the first maxim of Quality. In order to meet this goal, Gricean and neo-Gricean scholarship on the first maxim of Quantity and its consequences is revisited. Fourth, a number of linguistic realizations of withholding information are examined. It is argued that some of the examples found in the relevant scholarship, namely those that involve scalar expressions, qualify rather as lies. (shrink)

Sorensen says that my assertion that p is a knowledge-lie if it is meant to undermine your justification for believing truly that ∼p, not to make you believe that p and that, therefore, knowledge-lies are not intended to deceive. It has been objected that they are meant to deceive because they are intended to make you more confident in a falsehood. In this paper, I propose a novel account according to which an assertion that p is a knowledge-lie if it (...) is intended not to provide evidence that p but to make you stop trusting all testimonies concerning whether p, which is how they undermine your testimonial knowledge. Because they are not intended to provide evidence that bears on the truth of p, they are not intended to make you more confident in a falsehood; therefore, knowledge-lies are not intended to deceive. This makes them a problem for the traditional account, which takes the intention to deceive as necessary for lying, and an interesting example of Kant's idea that allowing lies whenever one feels like it would bring it about that statements in general are not believed.

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)

Deception has recently received a significant amount of attention. One of main reasons is that it lies at the intersection of various areas of research, such as the evolution of cooperation, animal communication, ethics or epistemology. This essay focuses on the biological approach to deception and argues that standard definitions put forward by most biologists and philosophers are inadequate. We provide a functional account of deception which solves the problems of extant accounts in virtue of two characteristics: deceptive states have (...) the function of causing a misinformative states and they do not necessarily provide direct benefits to the deceivers and losses to the targets.

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.

Epistemologists focus primarily on cases of knowledge, belief, or credence where the evidence which one possesses, or on which one is relying, plays a fundamental role in the epistemic or normative status of one's doxastic state. Recent work in epistemology goes beyond the evidence one possesses to consider the relevance for such statuses of evidence which one does not possess, particularly when there is a sense in which one should have had some evidence. I focus here on Sanford Goldberg's approach (...) ("Should Have Known," Synthese, forthcoming; and "On the Epistemic Significance of Evidence You Should Have Had," Episteme 2016, this issue); but the discussion will interest anyone working on epistemic defeat.

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)

The paper argues that the correct definition of lying is that to lie is to assert something one believes to be false, where assertion is understood in terms of the notion of the common ground of a conversation. It is shown that this definition makes the right predictions for a number of cases involving irony, joking, and false implicature. In addition, the proposed account does not assume that intending to deceive is a necessary condition on lying, and hence counts so-called (...) bald-faced lies as lies. (shrink)

Lying requires asserting a disbelieved proposition, that much is widely accepted in the debate on how to define lying. But what else is required? Does lying require a particular linguistic manner of expression, such as saying? Does the proposition asserted have to be false (and not merely disbelieved)? And does lying require an intention to deceive? The aim of this chapter is to provide an opinionated introduction to the debates on these questions that takes into account both theoretical considerations and (...) empirical data. (shrink)

Existing analyses of disinformation tend to embrace the view that disinformation is intended or otherwise functions to mislead its audience, that is, to produce false beliefs. I argue that this view is doubly mistaken. First, while paradigmatic disinformation campaigns aim to produce false beliefs in an audience, disinformation may in some cases be intended only to prevent its audience from forming true beliefs. Second, purveyors of disinformation need not intend to have any effect at all on their audience’s beliefs, aiming (...) instead to manipulate an audience’s behavior through alteration of sub-doxastic states. Ultimately, I argue that attention to such non-paradigmatic forms of disinformation is essential to understanding the threat disinformation poses and why this threat is so difficult to counter.

The traditional conception of lying, according to which to lie is to make an assertion with an intention to deceive the hearer, has recently been put under pressure by the phenomenon of bald-faced lies i.e. utterances that _prima facie_ look like lies but because of their blatancy allegedly lack the accompanying intention to deceive. In this paper we propose an intuitive way of reconciling the phenomenon of bald-faced lies with the traditional conception by suggesting that the existing analyses of the (...) phenomenon overlook a non-obvious category of hearers whom the speakers of bald-faced lies intend to deceive. Those hearers are institutions represented by the people involved, such as courts or secret police. We also criticize two recent rival accounts (Jessica Keiser’s and Daniel Harris’s) that attempt to save the traditional conception by saying that some bald-faced lies are not assertions, because they are conventional—rather than illocutionary—speech acts.

One of the lessons of the COVID-19 pandemic is that the lay public relies immensely on the knowledge of public health officials. At every phase of the pandemic, the testimony of public health officials has been crucial for guiding public policy and individual behavior. The reason is simple: public health officials know a lot more than you and I do about public health. As lay people, we rely on experts. This seems straightforward. But the COVID-19 pandemic has shown that public (...) health officials seem undecided as to what, precisely, their role is; are they providing the public information as it presents itself, or are they informing the public in a way that produces a desired or optimal outcome? In this article, I answer the following question: what are public health officials morally obligated to tell the public? As I see it, these are the main options: (1) public health officials should tell the full truth, regardless of outcome; or (2) they should tell partial truths or lies that are aimed to promote a socially optimal outcome. My answer to this question is that public health officials are only allowed to lie under very narrow and rare conditions. -/- . (shrink)

This paper refines the received analysis of deceptive lies. This is done by assessing some cases of lies that are supposedly not intended to deceive and by arguing that they actually involve sophisticated strategies of intentional deception. These lies, that is, merely seem not to be intended to deceive and this is because our received analysis of deceptive lies is insufficiently sophisticated. We need to add these strategies to our analysis of deceptive lying. The argument ends by presenting this refined (...) analysis. (shrink)

We conducted two experiments to determine whether common folk think that so-called _tell-tale sign_ bald-faced lies are intended to deceive—since they have not been tested before. These lies involve tell-tale signs (e.g. blushing) that show that the speaker is lying. Our study was designed to avoid problems earlier studies raise (these studies focus on a kind of bald-faced lie in which supposedly everyone knows that what the speaker says is false). Our main hypothesis was that the participants will think that (...) the protagonists from our examples lied without intending to deceive, and the results of our surveys confirmed this hypothesis: most of our participants rated tell-tale sign lies as lies not intended to deceive. Therefore, our analysis suggests that common folk think that some lies are not intended to deceive. (shrink)

In their paper published in 2017 in Philosophical Psychology, Ronja Rutschmann and Alex Wiegmann introduce a novel kind of lies, the indifferent lies. According to them, these lies are not intended to deceive simply because the liars do not care whether their audience is going to believe them or not. It seems as if indifferent lies avoid the objections raised against other kinds of lies supposedly not intended to deceive. I argue that this is not correct. Indifferent lies, too, are (...) either intended to deceive or are not lies at all, since they do not involve genuine assertions. (shrink)

This paper aims to differentiate between lying and irony, typically addressed independently by philosophers and linguists, as well as to discuss the cases when deception co-occurs with, and capitalises on, irony or metaphor. It is argued that the focal distinction can be made with reference to Grice’s first maxim of Quality, whose floutings lead to overt untruthfulness, and whose violations result in covert untruthfulness. Both types of untruthfulness are divided into explicit and implicit subtypes depending on the level of meaning (...) on which they are manifest. Further, it is shown that deception may be based on irony or metaphor, which either promote deceptive implicatures or are deployed covertly. Finally, some argumentation is provided in favour of why these cases of deceiving can be conceptualised as lying. (shrink)

As an empirical inquiry into the nature of meaning, semantics must rely on data. Unfortunately, the primary data to which philosophers and linguists have traditionally appealed—judgments on the truth and falsity of sentences—have long been known to vary widely between competent speakers in a number of interesting cases. The present article constitutes an experiment in how to obtain some more consistent data for the enterprise of semantics. Specifically, it argues from some widely accepted Gricean premises to the conclusion that judgments (...) on lying are semantically relevant. It then endeavors to show how, assuming the relevance of such judgments, we can use them to generate a useful, widely acceptable test for semantic content. (shrink)

This article discusses recent work on lying and its relation to deceiving and misleading. Two new developments in this area are considered: first, the acknowledgment of the phenomenon of lying without the intent to deceive , and second, recent work on the distinction between lying and merely misleading. Both are discussed in relation to topics in philosophy of language, the epistemology of testimony, and ethics. Critical surveys of recent theories are offered and challenges and open questions for further research are (...) indicated. (shrink)

Legal domains concerned with deception often recognize and regulate cases of negligent deception. The philosophical discussion of deception should follow suit, shifting from an exclusive focus on deception-as-wrongful-manipulation to a broader panorama that includes negligent deception and contemplates cases in which negligent deception may be wrong even when intentional deception about the same information may be permissible. Interesting philosophical questions then arise about what distinguishes negligent deception from mere misunderstandings and mistakes. Those questions require further thought about how relationships involve (...) epistemic cooperation and interdependence, and when such relationships generate responsibility for others’ mental contents.

This article defends the view that liars need not intend to deceive. I present common objections to this view in detail and then propose a case of a liar who can lie but who cannot deceive in any relevant sense. I then modify this case to get a situation in which this person lies intending to tell his hearer the truth and he does this by way of getting the hearer to recognize his intention to tell the truth by lying. (...) This case, and further cases that I develop from it, demonstrate that lying without the intention to deceive is possible. (shrink)

Donald Davidson once suggested that a liar ?must intend to represent himself as believing what he does not?. In this paper I argue that, while Davidson was mistaken about lying in a few important respects, his main insight yields a very attractive definition of lying. Namely, you lie if and only if you say something that you do not believe and you intend to represent yourself as believing what you say. Moreover, I show that this Davidsonian definition can handle counter-examples (...) that undercut four prominent definitions of lying: viz., the traditional intend-to-deceive definition, Thomas Carson's definition, Don Fallis's definition, and Andreas Stokke's definition.

Lying is a common phenomenon amongst human beings. It seems to play a role in making social interactions run more smoothly. Too much honesty can be regarded as impolite or downright rude. Remarkably, lying is not a common phenomenon amongst normally intelligent human beings who are on the autism spectrum. They appear to be ‘attractively morally innocent’ and seem to have an above average moral conscientious objection against deception. In this paper, the behavior of persons with autism with regard to (...) deception and truthfulness will be discussed in the light of two different ethical theories, illustrated by fragments from autobiographies of persons with autism. A systemizing ‘Kantian’ and an empathizing ‘ethics of care’ perspective reveal insights on high-functioning autism, truthfulness and moral behavior. Both perspectives are problematic from the point of view of a moral agent with autism. High-functioning persons with autism are, generally speaking, strong systemizes and weak empathizers. Particularly, they lack ‘cognitive empathy’ which would allow them to understand the position of the other person. Instead, some tend to invent a set of rules that makes their behavior compatible with the expectations of others. From a Kantian point of view, the autistic tendency to always tell the truth appears praiseworthy and should not be changed, though it creates problems in the social life of persons with autism. From a care ethics perspective, on the other hand, a way should be found to allow the high-functioning persons with autism to respect the feelings and needs of other persons as sometimes overruling the duty of truthfulness. We suggest this may even entail ‘morally educating’ children and adolescents with autism to become socially skilled empathic ‘liars’. (shrink)

This introductory paper aims to demystify the concept of untruthfulness. Drawing on the scholarship on deception, the author reports on a distinction between the (objective) truth and (subjective) truthfulness, as well as their respective opposites: falsehood and untruthfulness. An attempt is made to discriminate between truthfulness and sincerity, to notions which capture similar phenomena but have originated in distinct scholarly traditions. Further, the author depicts untruthfulness as an internally diversified construct and teases out its main subtypes. Some light is shed (...) on overt untruthfulness and covert untruthfulness, as approached in philosophical, cognitive and pragmatic literature. The paper closes with a description of the scope of the present Special Issue entitled “New theoretical insights into untruthfulness”. (shrink)
