… As Richard Hofstadter wrote in his seminal 1965 book, “The Paranoid Style in American Politics,” conspiracy theories, especially those involving meddlesome foreigners, are a favorite pastime in this nation. Americans have always had the sneaking suspicion that somebody was out to get us — be it Freemasons, Catholics or communists. But in recent years, it seems as if every tragedy comes with a round of yarn-spinning, as the Web fills with stories about “false flag” attacks and “crisis actors” — not mere theorizing but arguments for the existence of a completely alternate version of reality. …
While psychologists can’t know exactly what goes on inside our heads, they have, through surveys and laboratory studies, come up with a set of traits that correlate well with conspiracy belief. In 2010, [Viren] Swami and a co-author summarized this research in The Psychologist, a scientific journal. They found, perhaps surprisingly, that believers are more likely to be cynical about the world in general and politics in particular. Conspiracy theories also seem to be more compelling to those with low self-worth, especially with regard to their sense of agency in the world at large. Conspiracy theories appear to be a way of reacting to uncertainty and powerlessness. [cont.]
