These are fair criticisms but miss the crucial point... Academics publish in expensive OA journals because top journals and citation count remain the dominant factors in determining whether you get hired and whether you get promoted... This will not change unless the incentive structure changes

Skepticism is warranted. For robustness, we did few-shots prompting were we gave examples oh Q&A. We also repeated the test with just two categories absent/present. Performance was still poor.

Thank you for pointing this out. We chose the question format for automation of 30k+ questions and to avoid biases on phrasing. It is indeed dry. Would love to get suggestions on better formatting. To answer the second question, not yet. We'd love to for follow-up studies. Please reach out!

I agree. The 'sometimes' was unnecessary. While the findings of this paper may seem obvious to the history community, they aren't obvious to everyone (the article is published in a Computer Science venue). We definitely need more historians working on this :).
