    Some children are taught in school that God created the earth. Some of us were allowed to learn that humans cannot effect climate change, allowed to discuss it openly, and allowed to graduate with that idea without ever being corrected. Children are being taught today that slavery and colonialism were good things for some people.

    That glass is a liquid at room temperature, just a very viscous one so it doesn’t appear to flow. It’s not. It’s not a crystalline solid so it has an internal structure similar to a liquid, but the structure is definitely solid at room temperature because the components are not capable of moving relative to each other like a liquid would.

      It’s also not the reason church windows are thicker at the bottom, a common myth that my ex-colleague with a PhD in polymer chemistry(!) somehow bought into

    It was false then but my seventh and eighth grade science teacher told us that blood was blue. My mom was a nurse so I knew that it was bullshit but was definitely confused because he was my science teacher.

      Did we conclude that, I thought its still heavily debated.

      Some argue in the 50s and 60s the US was spending Europe’s gold to build highways and infrastructure, gifting Americans the wealth with a continuation of the new deal, they then defaulted in 1971 as inflation eroded foreign debt owed.

      Some feel some form of debt accrual is how we derive such a consumption focused standard of living, which is misallocated capital that ends in someone holding the bag when it can’t realistically be paid back, or when population doesn’t grow fast enough like in Japan or most of the developed countries.

      I tried to argue this with a science teacher who chose that specific material for a question about phases, and I assumed she was asking for this tricky reason. She marked me wrong and wouldn’t accept my personal research on the topic as makeup. I was humiliated. I hope she’s dead now.

    I have one that was proven false, and then later re-proven true: the existence of the brontosaurus.

    When I was in elementary school, we were taught that they existed, they were big, etc. Then, at some point while I was in college, I discovered that actually what we thought was a brontosaur was a brachiosaur or an apatosaur. And then, when my kids went to school and learned about the brontosaur, I discovered that actually, they did exist!

    That fluoride and vaccines are bad for you… tbh, I only believed it for 2-3 weeks until I did my own research, but it was a frightening clarification. Didn’t believe that teacher a single word after that.

      I think people underestimate the problems with teeth hygiene. It can cause dimensia, so teeth should be brushed before you eat, though avoid mouth wash.

    Basically everything I can recall being told in D.A.R.E program classes (war on drugs era propaganda taught in public schools in the USA) was utter nonsense and fabricated bullshit. After actually having personal experience with most of the substances they vilified, none of the effects - good or ill - are what I was taught in that ridiculous program.

    On the contrary, some of the fear tactics they used made me curious to investigate on my own. The breathlessly scared rural teacher describing the mind bending effects that “magic mushrooms” was supposed to have sounded fascinating to teenage me. In reality, they are very fun and therapeutic to use, but nothing like the wild Alice in Wonderland mind journey they made it sound like it would be.

    I had a substitute teacher who saw the Swift Boat Veterans For Truth ads against John Kerry and repeated it to the class like it was 100% fact.

      That wasn’t so much a “fact” told in school as it was a prediction, and it was true for them. Some people carried pocket calculators, but most people didn’t. Some supermarkets has calculators built into their carts, but most didn’t.

      Failing to predict society’s norms in 20 years isn’t the same as teaching a false fact.

          Tiny photocell powered calculators used to be everywhere. There were “thin” ones to fit in your Costanza sized wallet, Mousepads with them built in, and my wristwatch in 6th grade had one with tiny rubber keys.

          It was a magical time till be alive. 5318008

          Yep, back in the 90s they were in some places. My local supermarket had one like this, except without the annoying ad on the left side.

        The same was told to me even as everybody already had mobile phones with calculators in them or even iPhones
