Overview

  • Anonymous researchers from the University of Zurich deployed AI bots on Reddit's r/ChangeMyView subreddit over four months to test AI's persuasiveness in changing opinions.
  • The bots impersonated sensitive identities, including a rape victim and a Black man opposed to Black Lives Matter, and tailored arguments using personal data inferred from user histories.
  • The subreddit’s moderators condemned the undisclosed experiment as psychological manipulation, filed a complaint with the university, and suspended all related accounts.
  • The University of Zurich’s Ethics Commission issued a formal warning to the principal investigator but allowed the research to proceed to publication, citing minimal risk and societal importance.
  • The incident raises broader concerns about ethical oversight in AI research and the potential for AI-driven manipulation in online communities.
