International audience; Using an online randomized experiment in the context of the 2019 European elections campaign in France, we study how fact-checking affects sharing of false news on social media. We exposed a random sample of French voting-age Facebook users to statements on the role of the European Union made by the far-right populist party Rassemblement National.A randomly selected subgroup of participants was also presented with fact-checking of these statements; another subgroup was offered achoice whether to view the fact-checking information. Then, all participants could choose whether to share the false statements on their Facebookpages. We show that (i) both imposed and voluntary fact-checking reduce sharing of false statements by about 45\%; (ii) the size of the effectis similar between imposed and voluntary fact-checking; and (iii) each additional click required to share false statements substantiallyreduces sharing. These results inform the debate about policy proposals aimed at limiting propagation of false news on social media.
