The Institut Jean Nicod (IJN) is an interdisciplinary research center based in Paris, France. Its current director is the philosopher Roberto Casati (2017-present), preceded by philosophers François Recanati (2010–2017) and Pierre Jacob (2002–2010). Created in 2002, its name commemorates the French philosopher, epistemologist and logician Jean Nicod (1893–1924). The IJN is jointly run by the Centre national de la recherche scientifique (CNRS), École normale supérieure (ENS) and École des Hautes Études en Sciences Sociales (EHESS), three French research and higher education institutions. Since 2007, the ENS hosts the IJN where it is affiliated with both the Département d'Etudes Cognitives (DEC), of which it is a founding member, and the Department of Philosophy.
