Can Academia Suppress Un-PC Results?
Apparently not for long. According to a recent report from the Fraser Institute (seen via Winds of Change), there have been several instances in which a PC study was unveiled to great fanfare, only to be overturned a few years later by more evidence.
One lesson that we can draw from the examples given is that, when there really is evidence overthrowing a PC result, that evidence can get out within a few years.
Another lesson is that we can't trust claims that are much less than a decade old.
On the other hand …
The scientific community is set up to ensure that theories with evidence against them are refuted. It is not set up to remind people that there is inadequate evidence for an accepted theory. Falsifying a generally accepted theory will win you a Nobel Prize. Reminding people that a commonly-accepted theory has little evidence either for or against will get you almost nowhere. It will alienate those few members of the Scientific Establishment who really are bigots and—what's worse—it will bore the rest.
