@ElderWendigo @MiraLazine agree to disagree, a lot of those things I was definitely taught - if not in school then at least by adults who thought it common knowledge. Especially the nosebleeds (I had them all the time as a kid, and the amount of blood I ended up swallowing is..... A lot.) and knuckle cracking (my guess - started by teachers annoyed by kids making knuckle-noises during class)
Christopher columbus was definitely taught as an "American hero" up until he wasn't.

Pretty much all of these examples were pretty often and commonly debunked by all of my teachers, parents, and adult mentors. But that's exactly why lists like this are garbage, both of our experiences are anecdotal. You just can't make blanket claims about things like this about entire generations.

Columbus was more a lie of omission than outright falsehood. That item on the list was probably closest to a universal truth taught across the US, as long as you ignore any school with an indigenous student body. But, most of our teaching about any historical figures in grade school is a near obscene over-simplification of the actual people and events.
