This is generally done by the same people who use the term "elites" derisively. There's a culture - often promulgated by Libertarians
C'mon. Really? I'll be generous and assume that you have defended your findings against those who don't understand them too much to make a distinction between them and those who challenge standing on legitimate grounds. But you are unquestionably defending yourself against an attack which hasn't been made in this case.
The fact is, someone who has made significant contributions to their field deserves some job security.
Maybe they do and maybe they don't. But tenure in research (rather than in teaching) exists for the purposes of protecting the scientific inquiry as a process. It doesn't exist (even if it has come to be viewed as existing) for the purposes of rewarding those who advance that process.
It's not that these naysayers have a better system for who deserves tenure
naysayers? Really?? I don't know how to rationally defend against slurs. Nor do I feel like trying.
They don't want anyone to have such protections
What protections? It is the nature of the protection itself that is being discussed rather than who is deserving of it and who is not.
but what system involving human pecking order is
So you do agree that it is a pecking order rather than a protection of the truth-finding process. Welcome to the club.
And the fact is, the attack on professors, tenure, and the scientific elites in general is mostly coming from the corners that are trying to tear down science as an edifice in general.
Nonsense. Pure unadulterated nonsense. It is not an attack on professors. It is not an attack at all. It is an attempt to see what would create a better system for protecting scientific inquiry. You attempt to claim that is only needs to be protected from those outside of the scientific community. And you fail to recognize that it also needs to be protected from the weakness of human nature inside of the community. Orthodoxy is the problem that is being challenged -- not elitism.
