Published 2 months ago

Information can evolve as new evidence emerges; it’s a fundamental aspect of the scientific process. As our understanding of the world deepens, we need to revise what we know.

Below, we’ve gathered some of these users’ reflections on the facts that have changed since their school days. Take a look to explore what they have to share.

Bored Fox: Does anyone know where this myth started? I heard it was some chef who was trying to get people in his restaurant. :D

AceIt’s been around for decades in one form or another, most probably originated from the fact that they use radiation, and radiation is “bad”, right? More recent social media platforms and the tendency of some to believe any old conspiracy theory keeps the myth alive.

Comedy Clumbers: Could have been (heavy sigh) my mother. She made us LEAVE THE ROOM until it dinged. She might still do this, but I’m enforcing LC for my own mental health, so can’t say for sure.

#4 That the English language has comprehensive and consistent rules.

A lot of things that we learned about dinosaurs when I was in elementary school turned out to be wrong. We thought they were scaly and reptilian, turns out a lot of them had feathers, and were very brightly colored, and were more like birds in a lot of ways than reptiles. Dinosaurs we thought existed like brontosaurus, turned out to not have actually existed.

Just everything dinosaur. Everything dinosaur was wrong.

#9 Basically any idea promoted by the D.A.R.E campaign

#12 My teachers used to say “Video games will make you braindead.” Turns out video games were all about solving puzzles and problem solving and ended up increasing the cognitive abilities and critical thinking skills for children from a young age.

#13 Nerves can’t regenerate and electron orbitals are circles. Basically, science keeps getting better and I had no idea these had changed for a long time.

#14 That you have to do lots of extra curricular activities, sports, and volunteer work just to get into any colleg. Joke’s on them. I went to college 10 years after high school so none of it mattered.

#23 While I was in college biology our teacher said she was forced to teach us that cell walls were rigid because that’s what the text book said but, she told us, it was not true–the phospho-lipid cell wall had just been discovered. So we learned it wrong and corrected all at the same time.

#24 Just about everything they taught about nutrition was a lie… which is kinda insane when you think about it. An entire generation who doesn’t know how food works in your body

#25 Earth had 4 oceans. The 5th ocean plot twist was revealed to me in my late 30s. I didn’t know, guys!! Could someone please update Gen X when this stuff happens? There should at least be a weekly memo or something. We are all over here failing easy trivia questions because no one told us that there was a 5th damn ocean. ?

Shanilou Perera

Shanilou has always loved reading and learning about the world we live in. While she enjoys fictional books and stories just as much, since childhood she was especially fascinated by encyclopaedias and strangely enough, self-help books. As a kid, she spent most of her time consuming as much knowledge as she could get her hands on and could always be found at the library. Now, she still enjoys finding out about all the amazing things that surround us in our day-to-day lives and is blessed to be able to write about them to share with the whole world as a profession.

Got wisdom to pour?
