Clear+Vivid with Alan Alda: Season 31 Trailer

Alan and Executive Producer Graham Chedd look ahead to next season and some unexpected connections between our first guests. They include best-selling author Steven Pinker, and how you know that I know that you know that I know; psychologist Nicky Clayton and why crows are so smart; Erica Chenoweth and the power of peaceful protest; climate scientist Kate Marvel on why she gets emotional in her new book; and journalist Melanie Kaplan, who with her beagle Hammy explore together the murky world of animal experimentation.
