Study measures AI responses to 2026 Brazil election queries

An unprecedented study in Brazil tested how ChatGPT, Gemini, and Google's AI Overview respond to election-related queries ahead of the first round, running 1,269 executions between September 8-23. The study aims to assess AI behavior in a high-stakes political context, but findings are not yet public. This matters as AI platforms increasingly shape voter information access, raising concerns about bias and misinformation.
