This episode tells the story of Facebook’s 2012 emotional contagion experiment, when the platform quietly manipulated the News Feeds of nearly 700,000 users to see whether emotions could be influenced at scale. From there, it traces the larger pattern that followed, including the data harvesting scandal involving Cambridge Analytica and Facebook’s transformation into Meta. What begins as a single controversial study opens into something much bigger: a business model built on attention, behavioral prediction, and constant experimentation. This is not just a story about one research paper. It is about how the platforms that connect us also shape us, often without our knowledge, and why the experiment never really stopped.

Operation Popeye was a covert U.S. military weather modification program carried out during the Vietnam War with the goal of extending the monsoon season over parts of Southeast Asia. By artificially seeding clouds to increase rainfall, the operation aimed to disrupt enemy supply routes, flood roads, and make terrain more difficult to navigate. Kept secret for years, the program only became public after investigative reporting and later confirmation by government officials, raising serious ethical and legal questions about the use of environmental manipulation as a weapon. This episode explores what Operation Popeye was, how it worked, why it remained hidden, and what it reveals about the lengths governments may go to in the pursuit of military advantage.
