 According to a study by Andrew McKenzie-McHarg, in contrast, in the nineteenth century the term "conspiracy theory" simply "suggests a plausible postulate of a conspiracy" and "did not, at this stage, carry any connotations, either negative or positive", though sometimes a postulate so-labeled was criticized.Lance deHaven-Smith suggested that the term entered everyday language in the United States after 1964, the year in which the Warren Commission shared its findings, with "The New York Times" running five stories that year using the term.A conspiracy theory is not simply a conspiracy.
