Mind control has been studied by everyone from psychologists to hypnotists. Joel E. Dimsdale, distinguished professor emeritus in the Department of Psychiatry at University of California, San Diego, joins host Krys Boyd to talk about mind control in the realms of religion, politics and society – from the Iron Curtain to social media today. His book is called “Dark Persuasion: A History of Brainwashing from Pavlov to Social Media.”
