Conspiracy Theory
In 2013, Professor Lance Dehaven-Smith published the peer-reviewed book Conspiracy Theory in America with the University of Texas Press, explaining that the term “conspiracy theory” was manufactured and promoted by the CIA. Its original purpose was to attack those who questioned the Warren Commission’s report after the Kennedy assassination. The CIA later heavily pushed the term’s use in the media.

Official website of the former U.S. Assistant Secretary of the Treasury for Economic Policy:
The term “conspiracy theory” was invented by the Central Intelligence Agency to discourage skepticism toward official government reports
Ron Unz reported on the cold reception given to this extensively researched book Conspiracy Theory in America, whose conclusion is that WWII hero General George Patton was murdered by the CIA after becoming a forceful critic of Washington. http://www.unz.com/runz/was-general-patton-assassinated/
The book was ignored because the U.S. media and public were shaped to see the American government as the truth-teller and those who expose government crimes as “conspiracy theorists.”
Ironically, the American left has been the main executor of the CIA strategy of silencing skeptics by labeling them conspiracy theorists.

It outlines how to smear and suppress conspiracy theorists:
· Claim that so many people could not stay silent about such a large conspiracy
· Have CIA-friendly people attack conspiracy claims and steer discussion toward “official” reports
· Claim that eyewitness testimony is unreliable
· Claim it is all old news because “no significant new evidence has appeared”
· Simply ignore it unless discussion of it has already become too active
· Claim that speculation and questioning are irresponsible
· Accuse conspiracy theorists of being overly obsessed with their theories
· Accuse conspiracy theorists of having political motives
· Accuse conspiracy theorists of promoting conspiracy theories for financial gain
In other words, as early as the 1960s the CIA created a theoretical basis for suppressing conspiracy theories and made it part of psychological warfare.
