Specifically, in April 1967, the CIA wrote a dispatch which coined the term “conspiracy theories” … and recommended methods for discrediting such theories. The dispatch was marked “psych” – short for “psychological operations” or disinformation – and “CS” for the CIA’s “Clandestine Services” unit.
The dispatch was produced in responses to a Freedom of Information Act request by the New York Times in 1976.
