American Conspiracy Theories

Abstract

Abstract Conspiracies theories are some of the most striking features in the American political landscape: the Kennedy assassination, aliens at Roswell, subversion by Masons, Jews, Catholics, or communists, and modern movements like Birtherism and Trutherism. But what do we really know about conspiracy theories? Do they share general causes? Are they becoming more common? More dangerous? Who is targeted and why? Who are the conspiracy theorists? How has technology affected conspiracy theorizing? This book draws on three sources of original, systematic, data—120,000 letters to the editor of the New York Times and Chicago Tribune from 1890 and 2010, a two-wave survey around the 2012 presidential election, and a representative sample of Internet discussions—to offer the first century-long view of these issues. Many popular explanations find little support, but an explicitly political explanation fares well. To succeed, conspiracy theories need to follow a strategic logic that mirrors shifts in power. From this perspective, conspiracy theories are a form of threat perception that tracks foreign and domestic power asymmetries to focus attention, integrate groups, and recover from setbacks.
