The media are increasingly displaying fact-checking work, particularly in the political field, through fact-checking formats and headings. However, some of these same media also continue to propagate false information. This apparent paradox can be explained by the history of fact-checking, which originated in the United States in the 1920s and whose modern version is a reinvention, or even an adaptation to the economic and editorial constraints to which the media are now subject. This desire to scrupulously verify journalistic content seems to have turned into a strategy of ostentatious verification.
