Among the Truthers: A Journey Through America's Growing Conspiracist Underground is a 2011 book by Canadian journalist Jonathan Kay that examines the popularity of conspiracy theories in the United States.

[1] Though much of the book focuses on the 9/11 Truth movement[2] Kay also discusses conspiracy theories about the Bilderberg Group, vaccination, and Reptilians.

He argues that many people prefer explanations for disasters which feature expansive conspiracies because it is more difficult to cope with the underlying incompetence or vulnerability at the root of such events.

[3] Sonny Bunch of The Wall Street Journal similarly argued that Kay unfairly exaggerated the extent to which political correctness promotes conspiratorial thinking.

The reviewer accurately predicted that advocates of the 9/11 Truth movement would dismiss Kay's analysis as a biased right-wing treatment of the issue.
