Plots, Designs, and Schemes: American Conspiracy Theories from the Puritans to the Present

The book offers three central insights:

1. The American predilection for conspiracy theorizing can be traced back to the co-presence and persistence of a specific epistemological paradigm that relates all effects to intentional human action, the ideology of republicanism, and the Puritan heritage.

2. Until far into the twentieth century, conspiracy theories were considered a perfectly legitimate form of knowledge. As such, they shaped how many Americans, elites as well as “common” people, understood and reacted to historical events. The Revolutionary War and the Civil War would not have occurred without widespread conspiracy theories.

3. Although most extant research claims the opposite, conspiracy theories have never been as marginal and unimportant as in the past decades. Their disqualification as stigmatized knowledge only occurred around 1960, and coincided with a shift from theories that detect conspiracies directed against the government to conspiracies by the government.
