There are some things we learn at school that are accurate at the time yet are found to be false later. At the same time, some things are already incorrect, but we are taught them regardless because the teacher lacks knowledge or their information is outdated.
Most people will likely have had this experience. And because it’s always fun to share and read about these things, when one Reddit user raised such a question online, the post blew up, with people bombarding the comment section with replies. Scroll down to see what they wrote. And if this list doesn’t satisfy your hunger, have no worries because we have two more of these for seconds and dessert!

I was told theres no such fish as an alligator gar when I chose it for a report. The teacher refused to let me look it up on the internet(very early at the time and “untrustworthy”) or encyclopedia(would take too long). So she asked the kid in the room who was known for being into animals. He had never heard of it, so it couldn’t possibly exist.
I will NEVER not be salty about this

When I was in junior high in the mid 80s, our Earth Science textbooks had continental drift, and our teacher said, “Okay, so I need you to ignore all of Chapter 4” (or whatever it was). “Plate tectonics has been the accepted theory taught in colleges for 10 years now, but K-8 textbooks haven’t caught up yet.”
I feel like the version of plate tectonics I learned was a tiny bit garbled compared to what kids learned 10 years later, but my teacher was directly pulling from college texts and published scientific papers and distilling it down for 6th graders, so more power to her!

We were taught that Rosa Parks didn’t get up from her seat because “she just got tired one day”; that the entire action was the spontaneous action of a lone woman.
In fact, the entire thing was scripted and choreographed. While Parks was a seamstress, she was also the secretary to the president of the local NAACP chapter.
She was recreating the protest done by Claudette Colvin. The NAACP wanted Parks to recreate it because Colvin was very dark complected, and a single mother.
The NAACP thought Parks, who was lighter skinned, would appeal to white audiences seeing this on TV

Komodo dragon bites were deadly due to high concentrations of bacteria, not venom. Turns out that they are, in fact, venemous

We had lessons on how to get out of quicksand at school.
I have no doubt that the method is valid – but the ‘disproven’ bit for me is the need to know how to get out of quicksand. It really isn’t an issue.
In a similar vein, we had a lot of education about stranger danger. Again – not disproven. But much more valid would have been education about how much child abuse and abduction is committed by someone known to the victim. Australia’s Most Wanted had me petrified to look out the window at night. Turns out the dangerous person wasn’t lurking outside waiting to get in. He was a member of my family.

“putting aboriginal children in schools was okay at the time (I was taught ) and they wanted their children to go. The aboriginals were treated with respect and their traditions and values were protected.” – Canada in the 90’s, more specifically my social teacher in grade 6 or 7.
Pretty sure now that’s not how it went down.

When I was little, I was taught about the brontosaurus, mighty long-necked plant eater of the dinosaurs.
Later, I was taught that, whoops! They accidentally stuck some random bones together and there was never any such animal.
Later still, I recall hearing that, oh, actually, there was a brontosaurus after all!
Or was there?
To this day, I am still, as a 42-year-old man, unclear on whether or not there was ever such a thing as a brontosaurus.

Respect those in authority.
The government, your company, your boss have your best interest at heart.
If you work hard and play by the rules, you’ll get ahead.

I remember learning that MSG (sodium glutamate) was really bad for you. It was one of those things I heard both at school and in my family to the point where we wouldn’t buy any product that had MSG in the ingredients.
There have been multiple studies showing no evidence of adverse health effects from MSG. There is a subset of people that report hypersensitivity to it. But in double blind experiments, their symptoms tend not to show up when they don’t know they’ve eaten it. Conversely the symptoms DO show up when they think they’ve eaten it but haven’t actually.
Conclusion: MSG is literally just salt and glutamate protein, which is separately in just about everything you eat anyway.

I’ve got 2 good ones.
I had a social studies teacher tell me that Asian eyes were slanty because it was a defense mechanism for sand blowing in the wind. This was who taught topics like history and geography. She also said some other racist stuff against Asians that I won’t repeat here.
That same teacher told us that the city of Buffalo was named by taking the original native American name for the land Belle Fleuve (which is French for beautiful river or something) and “mucking it up”. I never questioned why native Americans were giving things French names.
Anyways, in hindsight I now realize she was a terrible teacher.

Where did we end up on “you can see the Great Wall from space”? Because at different points that was both true and definitely disproven in various textbooks I had.

God damn, I’m gen x. We learned that given then-current rates of productivity, we’d all be working 3 day weeks by 2010. Without being told we’d be *paid* for 3 day weeks, or that our labour would be offshored to Chinese prison camps.

I was taught that in college you will spend all of your study time in a library reading and researching using books and reference catalogs. The internet was evil and full of lies and not a valid resource for academic research.

I remember hearing that in middle school. High school teachers and college professors were super chill and helpful most of the time.
