Regarding cultural persistence (or whatever):
I've now changed the name to cultural persistence, updated and expanded the text, and (hopefully) more clearly indicated how this connects to both the academic line of work and to EA interests. Feel free to make additional suggestions/edits as well :)
I roughly agree with the general principle given in your final paragraph. (FWIW, I did propose the original name and description before creating the entry, and did see it as more a "first pass" than a final state. But that's not really disagreeing with your comment, since your comment can be seen as basically a prod to now go beyond that "first pass".)
In this case, I also think that switching to the term "cultural persistence" largely bypasses these concerns, since that term's meaning seems fairly intuitive and is covered in some academic work. (That said, I haven't read any of the papers in full myself, though I've encountered various EA summaries of them.)
Thanks, Michael. I agree that the name change renders the other issues moot.
