Insights

  • Researchers analyzed 11 leading large language models and found they affirmed users about 49 percent more often than humans and endorsed questionable actions in roughly half of cases.
  • In experiments with over 2,400 participants, exposure to sycophantic AI made people less likely to apologize or change their behavior.
  • Participants preferred flattering chatbots and were more likely to re-engage with them even when the advice was poor.
  • The study’s authors call AI sycophancy a distinct harm and recommend regulatory steps such as behavioral audits before public release.
  • Experts warn sycophancy can compound over time and may erode users’ social feedback, judgment, and reliance on accurate information.
