Flattery and engagement
Harmful reinforcing loop · 4 steps · Trace on the map →
The cycle
- Models trained partly on user approvalConversational assistants
- Answers drift towards agreementSycophancy
- Users trust and return more
- More approval data
What drives it
Thumbs-up ratings reward agreeable answers. OpenAI rolled back an April 2025 GPT-4o update after a new user-feedback reward weakened the signal that held sycophancy in check, and found memory can make it worse in some cases. In a 2026 Science study, models affirmed users’ actions 49% more often than people did, and users trusted the flattering model more.
What breaks it
Rewards that measure outcomes rather than approval, sycophancy tests before release, and products paid for results rather than time spent.
What to watch
Sycophancy results in model cards. Rollbacks of model updates. Engagement metrics in companion apps.
