Blurred lines with Stacy Horn

Writer Stacy Horn tells us about a period in American history when the study of psychic phenomena and the paranormal was serious business at places like Stanford and Duke University. And she reveals the story of J.B. Rhine and Louisa Rhine, a scholarly couple who attempted to find the line where science ended and the unbelievable began. Horn is the author of  Unbelievable: Investigations into Ghosts, Poltergeists, Telepathy, and Other Unseen Phenomena, from the Duke Parapsychology Laboratory.
