Disinformation

Disinformation is false or misleading information that is spread deliberately to deceive. This is a subset of misinformation.

The English word disinformation is from the application of the latin prefix dis- to information making the meaning “reversal or removal of information”. The rarely used word had appeared with this usage in print at least as far back as 1887. Some consider it a loan translationof The Russian dezinformatsiya, derived from the title of a KGBblack propaganda department. Joseph Stalin claimed he coined the term, giving it a French-sounding name to claim it had a Western origin. Russian use began with a “special disinformation office” in 1923. Disinformation was defined in Great Soviet Encyclopedia(1952) as “false information with the intention to deceive public opinion”. Operation INFEKTION was a Soviet disinformation campaign to influence opinion that the U.S. invented AIDS. The U.S. did not actively counter disinformation until 1980, when a fake document reported that the U.S. supported apartheid.

The word disinformation did not appear in English dictionaries until the late 1980s. English use increased in 1986, after revelations that the Reagan Administration engaged in disinformation against Libyan leader Muammar Gaddafi. By 1990, it was pervasive in U.S. politics; and by 2001 referred generally to lying and propaganda.
