I think the biggest one that was drilled into us constantly, especially about WW2 and Nazis was

“ Those Who Cannot Remember the Past Are Condemned To Repeat It”

This was a load of shit as evidenced by what is going on in the USA right now and other parts of the world. The real lesson should have been to push back the second a nazi takes an inch as they will take more if you play the nice and tolerate. Not everyone is well intentioned.

1987 Edison was a genius and invented everything, Turns out he was actually the Elon Musk of his time.

''You won't have a calculator in your pocket all the time!''

A short list of things you didn't realize were false, stolen from the most recent episode of the You Are Not So Smart podcast (on Intellectual Humility, Sept 14 2025):

• "The original 1938 radio broadcast of The War of the Worlds lead to a mass panic." -- It did not. However, rumors of a panic spread via newspaper op-eds about how it was a bad idea to get your news through any other medium besides newspapers.

• "You can boil a frog in a pot by gradually raising the temperature of the water." -- This doesn't work; frogs just jump out when they get uncomfortable. Citation: https://en.wikipedia.org/wiki/Boiling_frog
• "Lemmings march off cliffs to their deaths because they blindly follow one another." -- They don't. Citation: https://en.wikipedia.org/wiki/Lemming#Misconceptions
  • "...but I saw it in a Disney documentary!" -- Nope. Turns out the filmmakers paid local kids to capture a bunch of lemmings, spin them around to make them dizzy, then manually threw them off cliffs and filmed it.

USA is a democracy

The mitochondria better still be the power house of the cell. Or we are going to flip some tables and burn the place down.

The very architecture of the Internet (it was a written with a capital I back then) made it impossible to take over, and traffic would naturally route around any damaged links or nodes.

Google and CloudFlare have since proven that sonsabitches with enough money can subvert it completely, and it only takes a few dudes dragging an anchor from a boat to disconnect entire countries for weeks and months.

When I was in school, we were taught that vaccines work. /s

Class of 2003.

Food wheel was taught in elementary school. As were the taste bud "zones" and the American Dream.

I don't care if it's wrong, Marilyn Manson had his ribs removed so he could blow himself

The United States is a constitutional Republic/democracy with 3 co-equal branches of government...

The one that immediately springs to mind doesn't exactly fit the criteria, because it wasn't even true at the time that I was taught it in public school in Texas. But my history teacher taught me that no real historian called it the "American Civil War," and that it was correctly called "The War of Northern Aggression." And, of course, although the Confederacy did want to keep slavery legal, their actual central reason for seceding was "states rights."

Like I said, both of those are simply lies. Only propagandists call it "The War of Northern Aggression", and it was always explicitly about slavery.

The sad thing is that I believed and repeated these lies for years after that. Note that, like most people, I didn't have access to the internet to easily check things myself. Since at the time I had zero interest in reading about history, it was difficult to correct my knowledge.

It has demonstrated, to me at least, the importance of keeping propaganda away from children. The more you lie to children, the harder it will be for them to become functioning adults.

For me it's the regions of the tongue thing. It never made any sense, and a 6 year old with a sugar cube could have disproved it. Yet they taught it in schools for years.

Five senses; taste, touch, smell, sight, hearing, acceleration, temperature, body configuration, pain, balance, time, hunger....

I guess the big one for me is the whole Mozart for babies thing. It wasn't Mozart's music making babies and young children smarter, it was a combination of more affluent parents or at least parents with college plus educations having time and income to spend on enrichment activities.

We had to write angry letters to our children's school about 5 years ago to get them to stop teaching taste regions. It's really baffling.

I can think of a few.

• That T-Rex' vision wasn't actually based on movement. (Probably)
• Feathered dinosaurs are a thing.
• What we were taught as the 'reservation' system more closely resembled concentration camps, and indigenous people were given a 'choice' between death marches and war.
• That the US military was actually on the wrong side of nearly every civilian movement for greater rights, from suffrage, to labor, and now freedom of speech and immigration.

That whole "got milk" campaign was a load of bullshit.

It turns out only about 30% of the global human population is able to even digest milk.

Work hard and you will be rewarded and taken care of. LOLLLLLLLLLL.

The book Lies My Teacher Told Me by James W. Loewen goes a long way to accomplish this. At least it did for me.

Oh I've got a good one. Learned in the American south. Supposedly the American Civil War was not fought over slavery, but differing railroad track widths. Slavery was a minor detail that was a scape goat for the north to force the south to use its standard railroad width.

Left brain/right brain pseudoscience

School experiences are too varied for such a site to exist. Examples:

Climate change was universally agreed upon to exist and be caused by people 30 years ago. For some reason it no longer appears to be.

Leif Erikson was taught to us back then but you’ll find people today that celebrate Columbus.

Alpha wolf is a lie.

Sure, some are still taught. Like you can catch a cold from being in the cold.

The constitution of the united States.

The US south treated their slaves well. Even in high school, I was like “mmmm you suuuure about that?”

The "tongues have taste zones" thing is the only thing that comes to mind.

When I graduated highschool, the idea that some dinosaurs had feathers and evolved into birds was still "fringe science".
