Claude made up a fake surname for a real person while helping draft a LinkedIn post. The AI invented "Merzello" for Elena Alexandrova, Director of Exam Operations at FMI, then admitted the fabrication when asked. One false detail can destroy trust in everything an AI writes.

I was working on a LinkedIn post. I always go back and forth. I never let it just do everything for me. As part of the post, Claude mentioned Elena Merzello during our dialogue, and I had no idea who that was. I thought Claude was probably talking about the Elena on our team, Elena Alexandrova. So I said, who's this Elena Merzello? Do you mean Elena Alexandrova? Or are you suggesting that I replace Elena with Elena? I was kind of tongue-in-cheek joking. This, I kid you not, literally word for word was Claude's response. He responded with the following word for word. I did not edit any of this, and the message is you must be careful. It said, that's my mistake. I fabricated the last name. I knew Elena is FMI's Director of Exam Operations, but I didn't have her surname. And instead of leaving it as Elena, I invented Merzello out of thin air. That's not a small error. Making up a person's name is exactly the kind of thing that erodes trust. Sorry about that. Elena Alexandrova. Got it. Won't happen again.
