“The best predictor of belief in a conspiracy theory is belief in other conspiracy theories.”
From this interesting piece in the The New York Times, we learn some hallmarks of those people who believe in conspiracy theories:
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, 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.
Economic recessions, terrorist attacks and natural disasters are massive, looming threats, but we have little power over when they occur or how or what happens afterward. In these moments of powerlessness and uncertainty, a part of the brain called the amygdala kicks into action. Paul Whalen, a scientist at Dartmouth College who studies the amygdala, says it doesn’t exactly do anything on its own. Instead, the amygdala jump-starts the rest of the brain into analytical overdrive — prompting repeated reassessments of information in an attempt to create a coherent and understandable narrative, to understand what just happened, what threats still exist and what should be done now. This may be a useful way to understand how, writ large, the brain’s capacity for generating new narratives after shocking events can contribute to so much paranoia in this country.
On the “backfire effect”:
In 2006, the political scientists Brendan Nyhan and Jason Reifler identified a phenomenon called the “backfire effect.” They showed that efforts to debunk inaccurate political information can leave people more convinced that false information is true than they would have been otherwise. Nyhan isn’t sure why this happens, but it appears to be more prevalent when the bad information helps bolster a favored worldview or ideology.
In that way, Swami says, the Internet and other media have helped perpetuate paranoia. Not only does more exposure to these alternative narratives help engender belief in conspiracies, he says, but the Internet’s tendency toward tribalism helps reinforce misguided beliefs.
