Editors van Ditmarsch, Hendriks and Verbrugge of this special issue of topiCS on lying describe some recent trends in research on lying from a multidisciplinary perspective, including logic, philosophy, linguistics, psychology, cognitive science, behavioral economics, and artificial intelligence. Furthermore, they outline the seven contributions to this special issue.

Groups, like individuals, can communicate. They can issue statements, make promises, give advice. Sometimes, in doing so, they lie and deceive. The goal of this paper is to offer a precise characterisation of what it means for a group to make an assertion and to lie. I begin by showing that Lackey’s influential account of group assertion is unable to distinguish assertions from other speech acts, explicit statements from implicatures, and lying from misleading. I propose an alternative view, according to (...) which a group asserts a proposition only if it explicitly presents that proposition as true, thereby committing to its truth. This proposal is then put to work to define group lying. While scholars typically assume that group lying requires (i) a deceptive intent and (ii) a belief in the falsity of the asserted proposition, I offer a definition that drops condition (i) and significantly broadens condition (ii).

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)

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)

In this chapter I argue that the traditional interpretation of the commonly accepted moral asymmetry between secrets and lies is incorrect. On the standard interpretation of the commonly accepted view, lies are prima facie or pro tango morally wrong, whereas secrets are morally permissible. I argue that, when secrets are distinguished from mere acts of reticence and non-acknowledgement, as well as from acts of deception, so that they are defined as acts of not sharing believed-information while believing that the believed-information (...) is relevant, the correct interpretation of the commonly accepted moral asymmetry between secrets and lies is that secrets are also prima facie or pro tango morally wrong, albeit less morally wrong than lies.
