In the world of Brexit, Donald Trump and Matteo Salvini, each day carries polemics. Yet behind the unbridled appearances of the populist carnival, lies the hard work of dozens of spin doctors, ideologists and, increasingly, scientists and Big Data experts who are reinventing the rules of the political game. In this book, Giuliano da Empoli portrays these engineers of chaos. From the incredible tale of the small webmarketing company that became Italy's first party, to the physicists who ensured Brexit's victory, to the strategists of the new American right and the communicators who changed the face of Eastern Europe, this exciting and unprecedented investigation reveals the backstage of the global populist movement.
