Mutually conflicting conspiracy theories often coexist:
[W]hile it has been known for some time that people who believe in one conspiracy theory are also likely to believe in other conspiracy theories, we would expect contradictory conspiracy theories to be negatively correlated.
Yet, this is not what psychologists Micheal Wood, Karen Douglas and Robbie Suton found in a recent study. Instead, the research team, based at the University of Kent in England, found that many participants believed in contradictory conspiracy theories. For example, the conspiracy-belief that Osama Bin Laden is still alive was positively correlated with the conspiracy-belief that he was already dead before the military raid took place. This makes little sense, logically: Bin Laden cannot be both dead and alive at the same time. An important conclusion that the authors draw from their analysis is that people don’t tend to believe in a conspiracy theory because of the specifics, but rather because of higher-order beliefs that support conspiracy-like thinking more generally. A popular example of such higher-order beliefs is a severe “distrust of authority.”
