Host Michael Taft speaks with author, science journalist, and psychology nerd David McRaney about what sorts of conversations actually cause human beings to change their minds; the fascinating on-the-ground research of groups like Street Epistemology and Deep Canvassers, the stories of people deciding to leave insular in-groups such as the Westboro Baptist church and 9-11 Truthers, the deep neuroscience behind "The Dress" phenomenon, the role of storytelling in human interactions, and much more.
