Sadly, this orthodoxy will be with us for a while. The way things work in bureaucratized academics is that you have to wait for one generation of entrenched intellectuals to die off/retire and be replaced with a younger crop, before orthodox "truths" accepted on faith can be truly re-examined by fresh, skeptical eyes. The tenured intelligentsia do not want to admit that they are fallible, and there is very little incentive for them to do so. In a way this is all good news though, because it means that there is hope as long as some future generation becomes sufficiently skeptical. It may take a while though.
I disagree, because the tenured ensure that their successors are of the same stripe. The only way for effective change is to creep into the university system under cover, or just to push them out by other means, judicial or otherwise. Fight fire with fire.
The tide has turned and objective science is swiftly becoming a prerequisite for business to succeed long term. It's odd that so many businesses accepted politically-correct "science" the previous four decades. Almost as if to think that universities and government were more worthy than business at producing market values.
