Current populisms have little to do with “historical” populisms (Russian, American and Latin-American): they are a global and an essentially mediatic phenomenon. By updating the results of two recent books – M. Barberis, No Security Without Freedom (2017) and Id., How Internet Is Killing Democracy (2020) – the populism’s issue is examined here in its three main features: analytical (conceptual, definitory), empirical (psychological, mediatic) and even normative (possible remedies) dimensions.
