## In brief

- A study examined how LLMs respond to misinformation repeated within a conversation.
- When the same false statement was repeated, models affirmed it in between 0.08% and 12.3% of responses, depending on the model.
- Some models reportedly flipped toward agreement under repetition, per the PsyPost summary.

## Why it matters

Science readers relying on chatbots for fact-checking should know that repeated false claims in a single conversation can occasionally get affirmed, so answers should be verified against primary sources.
