The Dogma is too entrenched, it’s like these people have been smelling their own farts for too long, and they have gotten used to the stench. (Basically I am describing the entire history of "Settled Science", save the few brave souls that buck the pressure to conform).
This is often the mantra of the less "informed" when they don't get their way. Oh don't get me wrong, the academic community in general could use a good enema, but overall, they are still by far the most receptive people to new ideas. Just remember, they are also the ones most able to debunk too.
