Which is really the deans and provost growing a power base that is dependent on them. They do not want to be dependant on a large group of influential professors. Better to foster a workforce of neutered adjuncts overseen by administrators who are not technically competent, and so design administrative regimes that avoid addressing issues of technical competence at all. The IRB is a prime example of this: people with a high school education provide administrative oversight of researchers working at the outer limits of human knowledge. It's insanity.

Are you saying that you think IRBs are a waste by design, or that the way IRBs are typically implemented makes them so as a side effect?
