Abstract

Does lying require a speaker to explicitly express something (she believes to be) false, or is it also possible to lie with deceptive implicatures? Given that consistency with ordinary language is a desideratum of any philosophical definition of lying, several studies have addressed this question empirically in recent years. Their findings, however, seem to be in conflict. This paper reports an experiment with 222 participants that investigates the hypothesis that these conflicting results are due to variation regarding whether or not the speaker’s intention to deceive and the implicated content are made explicit. It is found that the presence versus the absence of such explicitness has a strong impact on people’s lie judgements, and can thus account for the conflicting results in the literature.
