Sacha Meuter, Head of Research and Policy at Fondation Hirondelle, was interviewed for the RTS programme "On en parle". The programme welcomed some fifteen young people from the 10th year of Harmos who are doing an internship at RTS. It dealt with the theme of "How do we inform ourselves? On which platforms or media? How can we check that a piece of information, a photo or a video is true? What tools exist to detect fake news?" Joining Sacha Meuter to answer these questions is Cécile Tran-Tien, an RTS journalist and producer of the programme "Vraiment?".
