Originally a technical medical term referring to occupational disorders manifesting as physical malformations or diseases, such as back damage in horsemen, ,skin disorders in tanners (modern examples might be kidney disease in long-haul truckers and the epidemic of carpal tunnel syndrome among office workers) now used almost entirely to refer to the tendency of professionals in one field to be unable or unwilling to perceive phenomena outside their field of expertise except through their own professional perspective.

17,000 hits on Google, referring quite often to economists, also historians, doctors, lawyers, etc. Many hits in French, also many in German.

I didn't find any studies, but I think they might be easy to do, although the results might not be surprising enough to be publishable, since you'd be likely to find that, yes, professionals do have it. If you found a profession that could switch perspectives exceptionally easily, that would be very interesting indeed.

I wouldn't be surprised if highly creative people worked at doing it, as with Posner thinking of looking at economics in terms of the law, Gary Becker, etc.

It is the basis for many jokes, like the farmer, psychologist and physicist considering a problem in animal husbandry, and the physicist starting with "Let us consider the cow as a perfect sphere....." But for a really apropos joke it would have to have the professional unable to take on another perspective.

I agree with you that often A will defer to B because of B's expertise, but the bias refers to being unable or unwilling to do so.

I had never heard of deformation professionelle before. Are there some good studies on it you'd suggest reading?

It would seem to me that on many issues Profession A will simply defer to Profession B since A is lacking important insight that B has.
