Dear all,

The next presentation in the Online Social Choice and Welfare Seminar will be next Tuesday (28 April).   Here are the details.

Time: 2PM GMT (10AM Toronto/Montréal, 11AM Rio de Janeiro, 3PM London, 4PM Paris, 5PM Istanbul, 7:30PM New Delhi, 11PM Tokyo/Seoul)

Speaker: Kai Spiekermann (London School of Economics and Political Science)

Title:   "What are Social Norms?"

Abstract. Many theorists tie social norms to attitudes, such as expectations towards others, perhaps along with conforming practices. Challenging this view, we instead ground social norms in a social norming process, an often non-verbal social communication process that ‘makes’ the norm through mutual expressions of support. We present the process-based account of social norms and social normativity, and distinguish social norms from social pressures, social practices, and Lewisian conventions. The process-based view brings social norms closer to legal norms, by tying them to ‘expressive acts’, just as laws and contracts arise through acts of voting or signing, not through mere attitudes.

(Joint work with Franz Dietrich)
