In the post-World War II decades conspiracy theories have become more numerous, more commonly believed, and more deeply embedded in our culture, Goldberg contends. He investigates conspiracy theories regarding the Roswell UFO incident, the Communist threat, the rise of the Antichrist, the assassination of President John Kennedy, and the Jewish plot against black America, in each case taking historical, social, and political environments into account. Conspiracy theories are not merely the products of a lunatic fringe, the author shows. Rather, paranoid rhetoric and thinking are disturbingly central in America today. With media validation and dissemination of conspiracy ideas, and federal government behavior that damages public confidence and faith, the ground is fertile for conspiracy thinking.
