I was chucked into Christian school.

So... a lot of it.

Physical Vs chemical changes.

It was typically taught that physical changes are differentiated from chemical changes because they could be "undone" or that they had "no chemical reaction." Which was very confusing, because you can't uncut paper, and dissolving stuff in water clearly results in different chemicals being produced, yet both were examples of physical changes (actually the latter is sometimes taught as a chemical change). Furthermore, most chemical changes are actually reversible.

It has since been recognised that this classification is BS, and most changes actually exist on a continuum.

Making grimaces and being told that your face may remain that way if you don’t stop making them… 🤡

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

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

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!"

Supersize me was fake and tonsils are not a useless byproduct of evolution.

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

Haven't seen anybody post this but how gender and sexuality is, schools are so fucking about straight mom and dad only relationship and nothing else. Man and wife bullshit when there's infinite amounts of gender and sexuality and diversity out there. Fuck I hate Amerikkka

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.

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.

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

That America is the best and most free country in the world.

My sysadmin professor told me to not learn about tape backups because they are going away soon

Like 3 years later ransomware was invented

"Those bullies will be working at a gas station while you'll be the boss!"

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 “known” archaeology and anthropology from even just a couple decades ago.

-Coequal branches of government

-Separation of Church and State

-Life terms for SCOTUS ensures political impartiality

-The second amendment was so that we could defend ourselves (see: redcoats)

-Bohr system

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

Study and work hard will make you successful.

That CO2 makes up 0.03% of the atmosphere. But it was true then.
