Fun facts that most of you dumb-dumbs forgot about, but were in fact wrong in the first place:
In school, we "learned" that the Romans had widespread lead poisoning due to lead pipes. In fact, this theory has been disproved ages ago.

In school, we also "learned" that glass, over a period of centuries, actually flows. Apparently this is also wrong

And this is Massachusetts... capital of intellectualism.
PS, In case you were wondering:
For the first one, I was randomly reading about lead production in Wikipedia in the Roman Empire and got to thinking about why there was no mention of mass lead poisoning.. then I googled "lead poisoning Roman Empire".
For the second one, I was looking for a verb for making glass in an ancient factory in the form of "glass is being ____". I stumbled upon the glass sub-article by looking over the main glass article...
