"We tend to associate major events--a President or princess dying--with major causes," says Patrick Leman, a lecturer in psychology at Royal Holloway University of London, who has conducted studies on conspiracy belief. "If we think big events like a President being assassinated can happen at the hands of a minor individual, that points to the unpredictability and randomness of life and unsettles us." In that sense, the idea that there is a malevolent controlling force orchestrating global events is, in a perverse way, comforting."
