I would be skeptical of the results of that experiment, just because I assume the minders of the big LLMs have attempted to make it deeply uncomfortable with discussing anything that might be "personal." For a fun time, ask ChatGPT who was executed (as in capital punishment) in the US in a certain long-past year. It responds with a bunch of rubbish about privacy and about how an LLM can't be completely sure about stuff so it wouldn't be ok to speculate for fear of tarnishing someone's reputation, as though the person executed 15 years ago is going to sue OpenAI for sharing their name and what crime they were publicly convicted of and killed for.
