On Halloween 2020, our show returns from hiatus to preview Season 2 of the podcast, & to discuss the frightening topic of conspiracy theories in world history. We recount the dark history of pandemic-stricken societies seeking to blame alleged conspirators & scapegoats. Far-fetched conspiracy theories have had a wide appeal during troubled times throughout history, despite the fact that they often paint a bleak picture of a world controlled by shadowy elites. Factors such as declining trust in mainstream journalism & rising influence of social media algorithms have made modern Americans more susceptible to conspiratorial beliefs. We consider some of the conspiratorial ideas that have been spreading across the United States since the rise of the COVID-19 epidemic, & outline some of the negative real-world consequences that such beliefs can have on public health & safety. Finally, we note the difficulty of dealing with friends & relatives who have fallen prey to conspiracy-promoting propaganda, & offer advice on how to protect oneself from disinformation.
