 Conversely, Maximal Relevance does not imply or subsume Grice’s principles. For instance, nothing guarantees that the contribution with the most positive cognitive effects per unit processing cost is germane to the topic of the conversation or as informative as required (less informative contributions might have more positive cognitive effects per unit processing cost). As a result, Maximal Relevance does not predict what Barb implicated in example  (1).  The proposition I am not going to Peter’s party will have different effects than I am not going to Paul’s party, but seems as easy to process and could well have as many positive cognitive  effects.[57]  Only the proposition about Paul is relevant in the ordinary sense to what Alan asked, but this does not entail that it is maximally relevant in the technical sense of Relevance  theory.[58]
