– Would you like some coffee?
– Coffee would keep me awake.
Does that mean yes coffee, or no coffee? It depends! Is it the morning or the evening? Is the person trying to pull an all-nighter or take an afternoon nap? A computer looking strictly at the meanings of the words would be confused, but we humans do this kind of thing all the time without even noticing it.
In episode 11 of Lingthusiasm, your hosts Gretchen McCulloch and Lauren Gawne talk about the hidden assumptions of cooperation that we bring to every conversation. They were formulated by the linguist Paul Grice, and are known as the Cooperative Principle or Grice’s Maxims. Not only does stating these assumptions explicitly help us understand conversations where we exchange messages beyond the literal meaning of our words, but it also explains a lot of humour – many jokes rely on creative flouting of Gricean Maxims!
