That's interesting - we know that ChatGPT tends to compose "Schrödinger Facts" (https://sentientsyllabus.substack.com/p/chatgpts-achilles-heel), but I would have thought that it should be pretty straightforward to fix that by intersecting its statements with sources. As you noticed, getting that right seems to take more than just putting keywords into a Bing search.
Thanks!
@boris_steipe admittedly, my writing students back in the day sucked at figuring out what sources said too. And they were very smart college students.
