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 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)

Indifferent lies have been proposed as a counterexample to the claim that lying requires an intention to deceive. In indifferent lies, the speaker says something she believes to be false (in a trut...
