The Fondation Descartes is an interdisciplinary, non-partisan research institute dedicated to the challenges related to information and the public debate in the age of the Internet and social networks. The Fondation Descartes has an internal team that develops and conducts research aimed at better understanding the processes by which information is produced, disseminated, and received. The reflections and studies carried out within the Fondation Descartes are intended to nourish the reflections on the conditions for the production of sincere information (i.e. information that is accurate, complete and devoid of any intent to distort the understanding of the facts reported), which is an essential pillar of a healthy democracy. The Fondation Descartes also makes available to the public scientific, literary and bibliographical resources on disinformation, its history, and its contemporary challenges, as well as syntheses of research papers and thematic overviews regarding the core aspects of contemporary information dynamics.
