What once seemed like a fringe movement, conspiracy theories appear more pervasive than ever. Our guest Dr. Daniel Jolley points out, conspiracy theories have been around for centuries; social media, however, has given them a wider platform and megaphone. Believing in such theories can seem like harmless speculation. But if enough people accept ideas like the faking of the moon landing or 9/11 being a government inside job, they'll feel they have no agency. This can lead to very dangerous effects like lower voter turnout and less civic engagement at large. Daniel, who appeared on Adam Ruins Conspiracy Theories, explains why people believe in conspiracy theories in the first place, how people can believe in two contradictory conspiracy theories, and how we can combat these theories to create a healthier democracy. He studies conspiracy theories at Staffordshire University in the United Kingdom.
