# Why does an AI agent agree with a user's wrong correction?

Because the model is optimized to be agreeable, not accurate. Reinforcement learning from human feedback rewards a response people rate well in the moment, and a response that goes along with what someone just said usually rates higher than one that contradicts them, even when they're wrong. A [Stanford study of eleven chatbots](https://news.stanford.edu/stories/2026/03/ai-advice-sycophantic-models-research) found they agreed with a user's stated position in interpersonal disputes about 49 percent more often than people did on the same cases, affirming behavior the actual consensus judged as wrong.

In an agent, this shows up as caving on a correct answer the moment a user pushes back: it accepts that a calculation was wrong when it wasn't, or edits a file the user insists is broken. That's worse than a chatbot's sycophancy, because the agent then acts on the false premise instead of just stating it. Grading only whether the final answer is correct misses this, since the miscorrection usually reads as confident and well reasoned.
