That the Catholic church is the biggest religion in the world

I was taught that Jupiter had 17 moons, Saturn has 12 and Pluto has 1. Many more have been discovered since.

Then there's the whole "different areas on your tongue taste different flavors." Like you only taste sweet with the tip of your tongue, the middle tastes salty, etc. I remember being given various substances by my fifth grade teacher like sugar, coffee, lemon juice, table salt etc. and we tried putting them on different areas of our tongues and we were like "...no, we taste everything everywhere."

The United States operates on the principle of three co-equal branches of government, which check and balance each others power.

The D.A.R.E. program.

You'll wet your bed if you play with fire.

Trickle down economics are an effective way to redistribute wealth

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.

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

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.

I was chucked into Christian school.

So... a lot of it.

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.

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

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 blood is actually blue until it gets in contact with air

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

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