We may identify potential contributors and give relative rankings at least though. Although it is fuzzy we are pretty certain that it isn't because of say changes in underwear technology. I suspect tenure may be a bigger factor personally - especially for those whose careers are mainly academic instead of industry where they can always leave for greener pastures if they get fed up with it. There are toxic incentives to try to tear down rivals under any pretense so that sort of sniping may easily get embedded in the culture. It is just a theory of course.
