Professor Kathryn Lofton, Lex Hixon Professor of Religious Studies and American studies, Professor of History and Divinity, and Dean of Humanities at Yale University, joins me to discuss her Smith-Pettit Lecture delivered at the Mormon History Association Conference in June 2022, entitled "A Brief History of the Mormon Smile." We discuss Erving Goffman, affective performativity, American consumer capitalism, and the "missionary grin."
