A toned down term to replace "orthodoxy" in sociology of art

I think this community could help me a lot. In sociology of culture the term orthodoxy refers to ideas held by most and imposed by cultural institutions, so that the "doxa", or opinion, is maintained for a long time and is difficult to depart from. In art, this would easily apply to the academic art of the XVII to XIX centuries, but the closer you get to the second half of the last century and to our times, the more fluid these ideas get, because many cultural institutions compete and no institution can really impose ideas as strongly.

So I think a softened term would be needed instead of orthodoxy, so that one would be able to refer to ideas that are shared by many for some time. Ideally a neologism, replacing the prefix "ortho-" and keeping "-doxy", both to refer to "opinion" and to keep some familiarity with the term replaced. Could you help?
