In 2018 the whole world was scandalized to find out that a political data analysis agency, working together with Facebook, had played a decisive role in a disinformation campaign that contributed to Brexit and to Donald Trump’s election as US president. Carole Cadwalladr (United Kingdom) is an award-winning journalist who works for The Guardian and The Observer; this Pulitzer Prize finalist played an important role in bringing the story to light. Cadwalladr carried out a brilliant investigation that revealed some alarming facts: that Cambridge Analytica had used the data of at least 87 million Facebook users without their consent. The result? Cambridge Analytica filed for bankruptcy and Mark Zuckerberg, co-founder of Facebook, had to testify before the US Congress. The work of Carole Cadwalladr is proof that journalism can have great social and political impacts, but it also clarifies how much needs to be done: our democracies are under constant threat. What can we do about it? Cadwalladr will talk about this matter with Emma Graham-Harrison.
