This text offers an overview of conspiracism in the United States from the 1950s to the present. Even if contemporary conspiracy mongering extends certain practices and attitudes that were already well-known at the time of Richard Hofstadter’s classic study of the “paranoid style in American politics” (1964) and Robert Goldberg’s more recent study of “the culture of conspiracy in modern America” (2001, 2010), it also introduces new techniques by savvy strategists, such as Donald Trump and Tucker Carlson, who exploit the economic vulnerability of many and the status loss anxiety of many others to destabilize the faculty of judgment of American citizens, increase polarization and suspicion between opposing camps, and weaken confidence in public institutions and democracy. This new conspiracism, we claim, serves to console the most vulnerable and turn the attention of the American public away from a forty-year social trend (conspiracy or not) which would be a neoliberal globalization that deepens inequalities and advances most often with total impunity to advance the interests of powerful deciders and loyalists—the first being to retain power and their control over narratives of power. The paper concludes with some recommendations for combatting this highly cynical and corrosive new conspiracism.
