It's probably worthwhile to differentiate more by discipline. Some disciplines (e.g. medicine) have reasonably robust mechanisms they employ to correct errors. Some (e.g. poetry) don't focus on that so much.

Doctors, for instance, believe all sorts of things that are wrong, e.g. "bed rest is the best way to deal with back pain". You don't have to dismantle medicine to get them to believe otherwise--just point them at modern best practice, with evidence, and they'll tend to change. For instance, until recently, doctors believed "eating fat makes you fat". Now very few of them recommend a low-fat diet (with no other changes) for weight loss, because it's just wrong.

So when doctors have the wrong ideas about health issues that are not identical across races (or mistakenly believe there's a difference when there's not), there's an avenue to fixing the problem with a whole lot less effort than rebuilding medicine.

But the other areas, like theological studies? Dunno.
