In a professional capacity, or just from a question here?

We get asked the occasional conspiracy question all the time. Probably one of the most interesting one to debunk for me was Oswald in Mexico, although you also might like this one about a UFO-related quote.

The line between conspiracy theory and historical myths can be fairly blurry and "schools were designed to trained factory workers" can fall on either side of that line, depending on the context one hears the it.

I've done my best here, here, here, and here to debunk that theory and/or myth.

In the last one, I link to the Wikipedia article I wrote explicitly addressing the phrase "factory-model schools."
