WHY TALK? SPEAKING AS SELFISH BEHAVIOUR

Many theories of language evolution assume a selection pressure for the communication of propositional content. However, if the content of such utterances is of value then information sharing is altruistic, in that it provides a benefit to others at possible expense to oneself. Close consideration of cross-disciplinary evidence suggests that speaking is in fact selfish, in that the speaker receives a direct payoff when successful communication takes place. This is congruent with the orthodox view of animal communication, and it is suggested that future research be conducted within this context.
