JFK Assassination Logic: How to Think about Claims of Conspiracy

The mother of all conspiracy theories concerns the assassination of President John F. Kennedy. Many of its elements have even become part of American folklore: the single bullet, the grassy knoll shooter, and the mysterious deaths of interested parties.

JFK Assassination Logic shows how to approach such conspiracy claims. Studying Lee Harvey Oswald’s character and personality, for example, doesn’t help determine whether he alone shot the president, and our opinion of bureaucrats can often cloud our judgments. How people view the JFK assassination can be a model for how (or how not) to evaluate other conspiracy theories, including those generally considered dubious—such as President Roosevelt’s foreknowledge of Pearl Harbor, desert staging of the 1969 moon landing, and U.S. government involvement in 9/11—as well as those based on fact, such as Watergate.

John McAdams addresses not only conspiracy theories but also how to think, reason, and judge evidence in such cases. By putting the JFK assassination under the microscope, McAdams provides a blueprint for understanding how conspiracy theories arise and how to judge the evidence.
