In "The Square and the Tower," author Niall Ferguson explores the influence of networks on power structures throughout history. A significant example he discusses is the instance when Facebook propagated a false narrative claiming that Donald Trump had received an endorsement from the Pope. This incident highlights how misinformation can spread rapidly through social media platforms, influencing public perception and political discourse.

Ferguson's work emphasizes the interplay between traditional power hierarchies and modern networked communication. The incident with Facebook not only serves as a case study of digital misinformation but also raises questions about accountability and the role of social media in shaping political landscapes. It underlines the importance of critical thinking in the age of information overload.
