Word for the bias of a profession towards itself?

Question

I am looking for a word or phrase (possibly of the form "____ bias") that describes the bias felt by members of a profession towards their own profession, some of examples of which might be:

• An author is more likely to write about characters who are themselves authors, a playwright to write about playwrights, and a painter to paint about the experience of painters.

• An engineer will tend towards trying to solve the problems faced by other engineers.

• A politician is most attuned to the issues faced by people who work in politics.

Example sentence:

The engineers don't seem to feel the new project is as important as the old one, but that might just be their _____ bias.

Answer 1

The engineers don't seem to feel the new project is as important as the old one, but that might just be their _____ bias.

In most contexts, the answer would simply be "professional bias", but if the context is about one firm versus another, it could be "company bias" or "corporate bias".

Answer 2

Collegiate Bias / Collegial Bias

Although colleagiate is defined in relation to the word college, the word has generalised to also apply to colleagues or peers in a profession. The alternative word collegial suggested by @TheNate is similar and may be preferred due to its closer relationship with colleague.

Your question requests a word indicating a bias towards members of someone's own profession. Professional bias is a candidate, but the term carries a negative connotation, akin to a blind spot. Collegiate / collegial bias refers more strongly to the (positive) peer relationship than to the professional task. The idea is that to a person with a collegiate / collegial bias, peers tend to come to mind before non-peers.

Answer 4

Sounds like chauvinism

Prejudiced belief in the superiority of one's own gender, group, or kind: "the chauvinism ... of making extraterrestrial life in our own image" (Henry S.F. Cooper, Jr.)

Answer 5

I feel like this could be Confirmation Bias ('Myside bias' according to wikipedia, which sounds more in line with your description) with some illusory superiority mixed in. (https://en.m.wikipedia.org/wiki/Illusory_superiority)
