An excerpt from Stephen C. Levinson, “Interrogative Intimations: On A Possible Social Economics of Interrogatives” in Questions. Formal, Functional and Interactional Perspectives. ed. Jan P. de Ruiter. Cambridge: 2012.
Levinson sketches a model of conversation in which interlocutors measure both the semantic and the social value of information. In this scheme, the semantic measure would be apportioned in units called Carnaps (after philosopher Rudolf Carnap), the social in Goffman units (after sociologist Erving Goffman). The Goffman measure involves ongoing estimations of position relative to others, social costs (which might explain the reluctance, say, to ask a question), authority, expertise, and so on. It underwrites a “micropolitics” of conversation.
Levinson offers an analogy with the shell money system of Rossel Island, in Papua, New Guinea.
An economic model of social information transfer is not going to look like a modern market economy. It might perhaps have some passing resemblance to the “primitive” economics of pre-industrial societies, with multiple measures for specific goods (bushels and grosses, cords and cubits), and multiple barter and exchange systems. Take the so-called shell money system of Rossel Island…, which consists of twenty-odd denominations of shells, with no exact equivalences of value and a delimited arena in which they can be used — it offers only the faintest semblance of a market economy (the shells are usable, e.g., for bride price, the purchase of pigs, houses and canoes, but not for food or manual labour). Shells are stores not only of economic but of social value, and top shells have names, like the Koh-i-noor diamond. Gaining possession of an individually named shell is like being temporary owner of a Picasso: it is an individual, not a mass of multiple undifferentiated tokens, and it reflects glory on its owner. Large injustices and delicts can be atoned for by the assuaging properties of such shells, even if only on loan for a fortnight. Shells go in one direction in exchange for goods, services and immaterial benefits (like forgiveness) in the other; but because there is constant flow in both directions, and shells are borrowed from all and sundry with intended eventual repayment, the market is about as murky as subprime derivatives. Such a system, with a multitude of special factors, frictions and exuberant irrationalities, offers us a better picture of the economics of everyday social life than textbook market economics.
It also moves us well beyond the transactional “ask-bid” model of conversation I described, and found wanting, in an earlier post.
