A huge number of aspects of the US's geopolitical enemies, and its own mythologization of the Founding Fathers and early settlers.

There was also a really bad political test with liberalism on the left and conservativism on the right, and we had to take a test and put what we got in front of everyone, which was very strange.

That blood is actually blue until it gets in contact with air

[–] [email protected] 5 points 20 hours ago

Easy to proof: Vaccumated capsule to draw blood.
No contact with air and still red.

I would say "cursive is how adults write, you'll need to know it", but that wasn't true then either.

[–] [email protected] 9 points 1 day ago (1 children)

Cursive is such a bad way to write. I used to have to decipher sloppy cursive notes on how to check airplane fixtures. I even learned it in school!

The asteroid that killed the dinosaurs was seen as just one of several possible theories, rather than accepted fact.

That I was a republican. The teacher gave out this political alignment quiz that was incredibly biased asking things like "do you like lower taxes or higher taxes?" and "do you like more freedom or less freedom?" All the questions basically lead you to the same answers. So the entire class basically had the same result.

This was in middle school so I wasn't even politically engaged yet. I didn't realize how crazy this was until years later.

"You need to learn this because you won't always have a calculator on you!"

[–] [email protected] 41 points 1 day ago (2 children)

That wasn’t so much a β€œfact” 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.

wat

[–] [email protected] 6 points 22 hours ago

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.

Tiny photocell powered calculators used to be everywhere. There were β€œthin” 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.

In my college Econ 101 class I was taught that "economic liberalism" would lead to political liberalism. I knew that was a myth back then, but my professors insisted. Twenty years later we've got economic nationalism and political fascism taking over everywhere.

That tastes have specific regions on the tongue. We actually had to protest when that shit was taught at our son's elementary school. Don't know if it came up for our younger daughter.

Poor kids at school had old atlases where Germany was still separated. But I guess that's just obsolete and not false knowledge.

Trickle down economics (well, it's not like there was a time when it was true)

That humans came out of Africa once and then settled the rest of the world. In reality there was a constant migration of humans in and out of Africa for millennia while the rest of the world was being populated (and of course it hasn’t ever stopped since).

I love how much DNA analysis has completely upended so much β€œknown” archaeology and anthropology from even just a couple decades ago.

Taste buds are arranged by flavor in four sections of the tongue. Complete load of horseshit.

Multiplication tables (I still know them mostly). I have a calculator on damn near every device now.

Things will always get better <-- this one is the biggest lie of them all

[–] [email protected] 29 points 1 day ago (5 children)

The multiplication table is still fact even if you have a calculator.

We don't know what the appendix does, the whole pluto thing, I think the Oxford comma is going out of style, and cursive in general.

But I love cursive, mine was "very nice" according to my teachers.

I was taught to use the Oxford comma by my parents, Ayn Rand and God. I had a strange upbringing.

[–] [email protected] 2 points 18 hours ago

It’s useful, helps with the flow of the ideas, and is more like the sentence is spoken.

[–] [email protected] 17 points 1 day ago

Eh, Pluto isn't really something proven false, just that we found more objects like Pluto that made more sense in their own category. It's classification, like there weren't always separate categories for feature films and short films, there wasn't a separate category for dwarf planets when it was just Pluto.

Oxford comma is useful. I think what's getting popular is just complete disregard for spelling and grammar.

[–] [email protected] 18 points 1 day ago

Thank you for your continued support of the Oxford comma.

Broadly speaking, failing to put in effort does tend to lead to worse outcomes.

The appendix is a vestigial organ that doesn't actually do anything in humans. (It might still fit the definition of vestigial, but it's far from useless and we keep learning more about how valuable gut health is.)

Not only in School, even at university I was taught the DNA structure was solved by Watson und Crick. But they stole data from Rosalind franklin and even openly admitted it years later.
