The central claim of RT is that human communication crucially creates an
expectation of optimal relevance, that is, an expectation on the part of the hearer that
his attempt at interpretation will yield adequate contextual effects without spending
unnecessary effort. This means the communicator has "two related aims": first, "to
create some contextual effect in the hearer", and second, "to minimize the processing
effortthis involves"
