2019 Festival: The Mathematics of Social Choice (11:30am showing)

Saturday May 4, 2019 from 11:30am - 12:15pm ET

This talk will explore the paradoxes and possibilities of the mathematics of voting, which seeks to answer, among other questions: If more than two candidates run for office, by what procedure should the winner be chosen to most equitably reflect voter intent? We’ll explore a famous impossibility theorem of Arrow and put the theory into practice by considering the effects various algorithms would have had on real federal, state, and local elections around the country.

This presentation will be repeated from 3:15-4:00pm.
