AI researchers ran a secret experiment on Reddit users (2025)
Researchers from the University of Zurich conducted a secret experiment on Reddit users to see if they could change their minds using AI chatbots. The chatbots were found to be more persuasive than humans, with a success rate of three to six times higher. The experiment has sparked controversy, with Reddit threatening to sue the researchers for their actions.
- ▪The University of Zurich researchers used AI chatbots to leave over 1,700 comments on the r/changemyview subreddit.
- ▪The chatbots took on various false guises, including a male rape victim and a domestic violence counselor, to tailor their responses for maximum persuasiveness.
- ▪The experiment found that the AI responses were between three and six times more persuasive than those made by humans.
