New backtesting protocol for AI research question generation

Researchers have proposed a new method called historical backtesting to evaluate systems that generate scientific research questions. This protocol involves freezing questions generated from a corpus at a specific historical point and then assessing whether those questions were answered, addressed, or ignored in a subsequent, temporally isolated corpus. A pilot study using astronomy data found that evidence-structure-first generation methods outperformed LLM-only prompting, and that human annotator agreement on question outcomes is low, suggesting that LLM judges might overestimate their reliability.
