Sydney Levine is a postdoc working jointly with Iyad Rahwan (Scalable Cooperation Group, MIT Media Lab), Joshua Tenenbaum (Computational Cognitive Science Group, MIT Brain and Cognitive Sciences), and Fiery Cushman (Moral Psychology Group, Harvard). She is interested in moral judgements in adults, children, and artificial intelligence. In this episode, we discuss the morality of preschoolers, trolleys, cookie-eating squirrels, and attempting to define “the consensus” with the Moral Machine Project.
