Why bother to speak?
My new book 'Virtue signaling' includes this essay. It's available now on Amazon: https://amzn.to/2PTe0NH How did language evolve? The key problem comes from signaling theory: if other people are sharing useful information, it's useful to listen to them. But what are the evolutionary payoffs for sharing useful information in the first place? This video explores why people bothered to say anything true, useful, or interesting to each other -- given that most other species don't. PS apologies for the background noise in some of this video; we'll be more careful in future! These arguments about the evolution of language are also featured in my book 'The Mating Mind': https://amzn.to/2GQ2DAI For early access, exclusive content, & eccentric minds, join my Patreon Culture: / geoffrey_miller
