What about the increasing adaptive value of manipulative language use?

Abstract

Dunbar (1993) emphasizes the role of cooperative language use in the evolution of human linguistic capacity and neglects to consider the role that manipulative language use would have played. I argue that as group size and neocortieal size increased during human evolution, the adaptive value of using language to benefit oneself at the expense of others would also have increased. I discuss how selection pressures for manipulative language use would have operated in the contexts of mating, status striving, and social exchange.
