Formalization
Relevance Theory's central insights are formalized in the following two-part principle, the Presumption of Optimal Relevance (see Postface to Sperber and Wilson 1995, p. 270):
- The ostensive stimulus is relevant enough for it to be worth the addressee's effort to process it.
- The ostensive stimulus is the most relevant one compatible with the communicator's abilities and preferences.
