Is there a word/phrase capturing the meaning of "zeitgeist" but not focused on society as a whole? Another German loan would be fine.
Some of the examples at Word like "zeitgeist" for beliefs or Is there an English variant of "Zeitgeist" other than "spirit of the times"? are pretty good but don't connote everything I'm interested in (e.g., capturing both values and beliefs, suggesting temporality/changeability, being a noun and encompassing the entirety of thinking). In particular, "consensus" sounds too authoritative/permanent.
An example sentence: The XXX of archaeology favored "pots not people" over mass migration.
The best thing I can think of is just saying "zeitgeist of the academy" or "foo is in vogue in academia."
