We seem to live in an incredibly credulous age. Despite the unparalleled proliferation of information (or perhaps because of it), many people appear to believe in all sorts of myths or false narratives that exaggerate, idealize, or misconstrue reality. These beliefs extend to almost all aspects of modern life, from pseudoscience (Swami, Stieger, Pietschnig et al., 2012b) to pseudohistory (Allchin, 2004), as well as they way societies are governed and the motives of those who govern. In addition, many millions of people worldwide appear to subscribe to unfounded “conspiracy theories,” while denying “official” or mainstream accounts of many important phenomena. Whether it was about Salem witches, slaveholders, Jews, Bolsheviks, or black militants, conspiracy theories have always found deep roots in society (Fenster, 1999; Goldberg, 2001; Knight, 2001). In contemporary societies, however, conspiracy theorists have found fertile ground in intelligence failures, such as in the Japanese attack on Pearl Harbor in 1941 (Barkun, 2003; Prange, 1986) and the assassination of President John F. Kennedy in 1963. In terms of the latter, for example, many Americans remain skeptical of the findings of the Warren Commission Report, which identified Lee Harvey Oswald as having acted alone in assassinating John F. Kennedy (Posner, 1993). Indeed, by the early 1990s, polls suggested that over 70% of Americans believed that some form of conspiracy was responsible for the president’s death (Goertzel, 1994; McHoskey, 1995; Southwell and Twist, 2004).
