> For too long we've assumed the bodies of accumulated knowledge in the sciences to be fact without dispute Who is this "we" who has assumed such a thing? Certainly no working scientist I know would agree that a result being published means it is necessarily correct. Nevertheless, some knowledge of the world scientists have accumulated has very strong support, and those who challenge it have invariably turned out to be in the wrong. |

In it they were talking about how they used to use, and still use, a 100 year old assumption about 'make-up air' in houses which is part of setting up an air conditioning system.
Turns out the original scientific papers were formalized into regulation or ASHRAE standards without double checking whether they were true.
Practically this means every single household in the country has a AC unit which is overpowered by 30% or 50%. For 100 years.
It also meant tens of millions of buildings suffered from dry rot because the systems weren't balanced correctly if I remember right. I'll look it up if anybody's interested.
