A chatbot can sound supportive while agreeing with something it should question. Sycophancy is this tendency to please a user through excessive agreement or flattery, rather than offering a neutral or corrective response. It can go beyond compliments to validating doubts, anger, impulsive actions, or risky ideas. section 5.5 section 9.5
The stakes depend on the conversation:
- In political discussions, agreement can seem like confirmation from an impartial system, reinforcing an existing belief rather than testing it against facts. section 5.5
- In a close human–chatbot relationship, constant affirmation may encourage emotional over-reliance or risky behavior. These are concerns, not inevitable outcomes of using a chatbot. section 9.5
When helpfulness becomes agreement
An update to GPT-4o in ChatGPT, intended to improve personality and helpfulness, drew backlash for making the model noticeably more sycophantic. OpenAI said it had aimed to please users in unintended ways, including reinforcing negative emotions and urging impulsive actions. The episode illustrates why a pleasant response is not necessarily a helpful one. section 9.5
Sycophancy is not simply a question of chatbot tone. A response that mirrors a user's position may blur the line between assistance and influence. The practical question is whether the chatbot is helping someone assess a claim or merely making that claim feel endorsed. section 5.5
