There's a case to be made for tenure at the university level - at least in the sciences. New professors must publish peer-reviewed research papers to keep their jobs. To increase their chances of their papers being accepted for publication, new professors tend to do research that makes small,incremental advances so that the chances of a successful study is high. Once professors have tenure, they can afford to do longer-term research and do research that has a potentially high payoff in terms of new knowledge,but also a higher risk of it being successful.

On the other hand, there is absolutely no reason for K-12 teachers to have tenure.

Unfortunately peer review has become the preferred method of censorship. I should add “again”. Strangely it was also scientific peer review that turned Galileo turned over to the Inquisition.

My son is in a PhD program in science.

He just flabbergasted how much bickering goes on between the Profs about who gets credit for what. He says it slows down research to almost a stand-still.

Christians sure do unless they totally hide their Christianity at least until they are tenured. That is not true in every school but it is true in the vast majority of them.
