Study Finds Short AI Chats Reduced Belief in New Conspiracies
Participants were randomly assigned to a tailored debunking dialogue, an unrelated AI conversation, or a static list of contemporaneous facts.The dialogue groups completed at least five exchanges with Gemini 1.5 Pro in the first experiment and Gemini 2.5 Pro in the second. Differences from the static fact sheet were 5.60 and 6.56 points. The paper's strategy analysis found that the model leaned more on credible sources, open questions, and caution when little was known, then used more direct evidence when the second event had a larger factual record.The authors also report limited evidence of later spillover.
