 While Grice’s maxims enjoin the speaker to contribute the required information and do so perspicuously and briefly, they do not require the speaker to maximize information, perspicuity, or brevity when other things are equal. For example, Grice’s maxims do not predict that Barb implicated I am not going anywhere in  (1)  even though it is more informative than I am not going to Peter’s party, and may have a greater effects/cost ratio. Or suppose that in a discussion of a new prescription drug benefit, someone comments “It will take some money to fund that program”. The speaker would normally be engaging in understatement, implicating “The program will be very expensive”. Relevance theorists account for this by saying that because the proposition explicitly conveyed is trivial, and thus has few positive cognitive effects, the hearer will “recover” the more informative  proposition.[55]  Critics respond that countless propositions are more informative than the one implicated, such as “The program will cost trillions”, and seem as easy to process.
