Brazil has concluded a closely contested presidential election, with Luiz Inácio Lula da Silva winning a fourth term. The election also raised serious questions about Meta’s role in shaping the information voters receive. A new guide, How Meta Interfered in Brazil’s Elections, documents four ways the company affected the race: it approved illegal and misleading political ads, offered AI tools that treated candidates unequally, gave some political figures unusually high reach, and restricted content unevenly. Leaked internal messages, Meta employees, the Oversight Board, and others have all raised concerns that the Lula and Flávio Bolsonaro campaigns were treated unequally, though Meta blames technical incidents and denies favoring anyone. The guide also offers practical tools for testing platforms, auditing ad records, and preserving verifiable evidence. |
