Would have to be “Decoding the Gurus” [1]. It’s hosted by a Behavioral Anthropologist and a Psychologist, and they do a great job exposing popular grifters like Jordan Peterson. “Behind the Bastards” [2] is a close second. They give a more modern dissection of horrible people and prominent organizations throughout history. Not so coincidentally, they also have a mini-series on Jordan Peterson.
