  • "Probably didn't know we could map the human genome... but in 2003..."

    I graduated high school in 2003, and had already heard the human genome had been mapped before entering high school. It may not have been true at the time, but I never once heard that it wouldn't be completed due to the complexity. lol

    Actually quite a few of these were already being taught at my high school before it was more common knowledge. Like the stuff with Columbus and Edison. Which now makes me think my school was actually more progressive than I initially thought.

  • Cool concept but your site really needs some work done. I heard in school that lemmings would kill themselves and i went in the 2010s. This is only one such example, the best thing you could have done is map out which myths are most common where instead of the decade, and it would also be useful to add a important corrections list for the more important facts which you probably were misinformed about.

  • It just listed a bunch of myths and old wive's tales that no one at the time thought were very credible anyway. Literally all of the "facts" they list were common chain letter/email memes that everyone trotted out at parties to sound smart and hip. Nobody ever believed what DARE told us, we always knew Christopher Columbus was an asshole, and every first aid class I've taken recommended against the whole tilt you head back thing.

  • • Contrary to what DARE might have taught you, marijuana is not considered a substantial gateway drug, with the best evidence being limited in nature, and with most marijuana users not going on to use other drugs. (Source) Yeah learn all that DARE BS.

    • You were probably taught at some point that we'd never be able to map out the entire human genome due to its complexity. However, in 2003, we documented the first 92%, and in 2022 we documented the remaining 8%. (Source) nope I was told we will map it soon

    • This one got shared by school nurses all around, but did you know that you shouldn't tilt your head back if you have a nosebleed? This could cause you to choke or vomit as a result of blood going back into your throat, or - more severely - trigger a vomiting reflex and cause inadvertent harm. (Source) Nope but my mom is a doctor so I leaned from a lot from her

    • You were probably taught at some point that people in the time of Christopher Columbus all thought the world was flat. However, this is a myth that pervades history - most people knew the earth was a globe! (Source) Yup

    • On the topic of Christopher Columbus, you might've been taught that he was a pretty upstanding guy, or at minimum just that he was average in terms of morality. Take a second to Google his relationship to slavery and genocide. (Source) EHHH kind of, we talk briefly about him mass cutting off people hands and enslaveing people.

    • A common myth that gets thrown around a lot in health classes is that cracking your knuckles can cause arthritis. This, as it turns out, isn't true - it's perfectly safe to crack your knuckles as much as you'd like. (Source) Heard that in school mom said it was wrong, I heard both the myth and the fact

    • The original food pyramid was introduced in 1992, and seemed to imply that there were different tiers of 'importance' to what food you ate. Since changed in 2011, this was deemed an inaccurate and potentially harmful way to view food intake. Food is food after all! (Source) Nope never learned that there where tiers of food each part is good for you

    • A fun fact about taste for you - there is actually no such thing as a 'taste map,' or the idea that different areas of the tongue result in you tasting different things. At most, there's just different regions of sensitivity to taste! (Source) Nopw, saw taste map never learned that it was supposed to show where you taste things

    • You've no doubt heard of this myth, perhaps not just from school - the idea that we only use 10% of our brains. This isn't true - we use all parts of our brains, just at different times since each neural location has a specific purpose! (Source) Yeah heard that

    • Another common myth is the idea that Thomas Edison invented the lightbulb. He was in fact not the inventor, just someone who helped to optimize its efficiency. (Source) yeah heard that

    • There's a good chance when you were younger, you heard classical music in the classroom to try and make you smarter. However, this is a myth - there is no such link between music and intelligence (or that we can measure intelligence for another matter!) (Source) Yeah heard that

    • You've probably heard a lot about Thanksgiving being a supposedly peaceful gathering among Pilgrims and Indigenous Americans, but this is actually a myth - it led to a bloodbath brought on by colonial settlers. (Source) Yup heard that.

  • This is neat! Thanks for sharing :)

    • Agreed! Tho' there is so much more in each decade listing that could be shared. Science and knowledge continue to move forward.
