Dan Sperber & Deirdre Wilson (2008) A deflationary account of metaphors. In R. Gibbs (ed.), Handbook of Metaphor and Thought. (Cambridge University Press), 84-105.

Abstract: On the relevance-theoretic approach outlined in this paper, linguistic metaphors are not a natural kind, and “metaphor” is not a theoretically important notion in the study of verbal communication. Metaphorical interpretations are arrived at in exactly the same way as literal, loose and hyperbolic interpretations: there is no mechanism specific to metaphors, and no interesting generalisation that applies only to them. In this paper, we defend this approach in detail by showing how the same inferential procedure applies to utterances at both ends of the literal-loose-metaphorical continuum, and how both literal and metaphorical utterances may create poetic effects

Abstract: This work examines how people interpret the sentential connective “or”, which can be viewed either inclusively (A or B or both) or exclusively (A or B but not both). Drawing on prior work concerning quantifiers (Noveck, 2001; Noveck & Posada, 2003; Bott & Noveck, 2004) and following a relevance-theoretic line of argument, we hypothesized that conditions encouraging more processing effort would give rise to more pragmatic inferences and hence to more exclusive interpretations of the disjunction. This prediction was confirmed in three experiments.
