24 Common “Facts” Montanans Repeat That Aren’t True at All

Montanans and Americans across the country love a good “fun fact,” even when it’s completely wrong.

From classroom myths to dinner-table legends, some of these so-called truths have been repeated so often they’ve turned into cultural folklore.

Whether it’s about your brain, your body, or poor misunderstood Napoleon, these are the “facts” we’ve been confidently spreading for decades, without realizing they’re total nonsense.

You Only Use 10% of Your Brain

This one refuses to die. Somewhere, somehow, Americans decided that 90% of their brains are just sitting there like lazy couch potatoes.

In reality, brain scans show that humans use nearly every part of the brain over the course of a day, even when sleeping.

The myth likely started in the early 1900s when a psychologist speculated about “untapped potential.”

Hollywood ran with it, giving us movies where people unlock “100% brain power” and start reading minds or moving spoons. Cool idea, but false.

You already use your whole brain, so if you can’t remember where you parked, that’s on you, not evolution.

Napoleon Wasn’t Short

Americans love using “Napoleon complex” to describe short men with big egos, but the French emperor wasn’t particularly short for his time.

He measured about 5’6” to 5’7”, which was average height for an early 19th-century man.

The confusion came from differences between the French and British measurement systems.

The British heard he was “5 feet 2.” But that was in French inches, which were longer than the British ones.

Cue centuries of height jokes.

So yes, Napoleon may have been temperamental, but vertically challenged? Not really.

Cracking Your Knuckles Causes Arthritis

Your mom probably told you this one while glaring at your popping fingers across the dinner table.

But science says there’s no link between cracking knuckles and arthritis.

What actually happens is that gas bubbles form and collapse in your joint fluid. That’s the “pop.”

It’s not bones grinding together, no matter how horrifying your grandmother made it sound.

The only downside? It’s annoying to everyone else. So maybe save it for when you’re alone.

You Swallow Eight Spiders a Year in Your Sleep

You’ve probably heard this one at least once during a campfire story or late-night Reddit scroll.

The idea that spiders crawl into your mouth while you sleep is the stuff of nightmares, but it’s not remotely true.

Spiders tend to avoid humans. They can feel our vibrations, breathing, and heartbeat, and they’re not interested in exploring your snoring face.

So rest easy. The only thing crawling into your mouth at night is probably your own bad breath.

Bulls Hate the Color Red

The bullfighting myth has been around forever.

People assume the red cape makes bulls angry, but color isn’t the issue, it’s movement. Bulls are color-blind to red.

Matadors use red simply because it hides blood stains (grim, but practical).

The real trigger for the bull’s charge is the waving motion.

So if you ever find yourself in front of a bull, don’t worry about wearing red. Worry about moving.

Hair and Nails Keep Growing After Death

This one sounds spooky and scientific, but it’s not true.

After death, the skin dries and retracts, making it look like hair and nails are still growing.

In reality, growth stops when your body does. The creepy illusion is just dehydration doing its thing.

So no, your body isn’t secretly prepping for an undead manicure.

The Great Wall of China Is Visible from Space

This fact has been in American classrooms and trivia nights for decades. Unfortunately, it’s wrong.

The Great Wall isn’t easily visible from space without aid.

Astronauts have confirmed that it blends in with the landscape because it’s narrow and made of natural materials. Cities, roads, and airports?

Those stand out more clearly.

It’s still an incredible feat of engineering, but not your go-to landmark from orbit.

Vikings Wore Horned Helmets

Hollywood strikes again. From Minnesota mascots to Halloween costumes, Americans picture Vikings with big-horned helmets.

Reality check: they didn’t wear those.

Archaeological evidence shows Viking helmets were simple, conical, and horn-free.

The horned version came from 19th-century opera costumes, not battle gear. The real Vikings were too practical for something that could snag on a tree (or a sword).

Shaving Makes Hair Grow Back Thicker

Millions of Americans have believed this while staring in horror at their newly shaved legs or faces.

But shaving doesn’t affect hair thickness, color, or growth rate.

When you shave, the blunt tip of the regrowing hair feels coarser, giving the illusion of thicker hair. The real texture and color come from genetics, not your razor.

So shave if you want to. You’re not creating a monster, just a smoother version of yourself.

Goldfish Have a Three-Second Memory

If that were true, goldfish would spend their entire lives rediscovering the same castle in their tank. Research actually shows they can remember things for months.

Goldfish can learn feeding schedules, recognize their owners, and even navigate mazes.

They’re basically tiny, wet geniuses compared to what we gave them credit for.

So maybe apologize to your childhood pet for underestimating its IQ.

George Washington Had Wooden Teeth

He had some rough dental problems, sure, but none of his dentures were wooden.

His false teeth were made from a mix of human teeth, animal teeth, ivory, and metal.

Wood wasn’t used because it would rot and smell. The myth probably started because the materials discolored over time, giving a wood-like appearance.

It’s still gross, but less “crafts project,” more “18th-century nightmare fuel.”

Lightning Never Strikes the Same Place Twice

Actually, it does, and it loves to. Tall structures like skyscrapers and trees are magnets for lightning, often getting hit multiple times a year.

The Empire State Building, for instance, gets struck about 20–25 times annually.

The saying probably stuck because it sounded poetic and reassuring, not because it was true.

If you’re in a thunderstorm, don’t test this theory. Science already did.

Carrots Improve Your Night Vision

This one came from World War II propaganda. The British military spread the idea that their pilots’ excellent night vision came from eating carrots.

In truth, they were covering up their use of radar technology.

Carrots do contain vitamin A, which supports eye health, but they won’t turn you into a nocturnal superhero.

Still, eat your vegetables, but don’t expect X-ray vision.

Einstein Failed Math

This story probably comforted generations of struggling students, but it’s false. Einstein was a math prodigy who mastered calculus before high school.

The myth began because of a misinterpretation of his school’s grading system.

People thought he’d flunked when, in reality, he’d achieved the top mark.

So next time someone says “Einstein failed math,” remind them he invented equations we still struggle to understand.

Dogs Only See in Black and White

Good news for Fido, his world isn’t as dull as once thought. Dogs can see colors, just not as vividly as humans.

Their vision is similar to a person with red-green color blindness.

They can distinguish blues and yellows but not reds and greens.

So while that bright red toy might not look as fun to them, they can definitely tell it apart from a tennis ball.

Basically, dogs see the world in a cozy, muted filter, like a permanent Instagram preset.

Gum Takes Seven Years to Digest

This one has haunted playgrounds for generations. The truth?

Gum doesn’t stay in your stomach for seven years. Your body can’t digest it, but it passes through your system just like any other indigestible food.

It might bounce through slowly, but it’s not clinging to your insides like an old piece of duct tape.

Still, it’s not a good idea to swallow it. Gum belongs in the trash, not your digestive tract.

Humans Evolved From Monkeys

This one’s half-right, which makes it even trickier.

Humans didn’t evolve from modern monkeys; they share a common ancestor.

Think of it like distant cousins who took different paths millions of years ago. One became a human, the other a monkey.

So next time someone says, “We came from monkeys,” you can gently correct them, without sounding like you’re auditioning for a TED Talk.

Coffee Stunts Your Growth

Every diner waitress and worried parent has warned about this, but there’s zero scientific evidence that coffee affects height.

The myth started when early studies linked caffeine to calcium loss, but later research debunked that connection.

So your morning latte isn’t shrinking you.

The only thing coffee stunts is your ability to nap afterward.

Touching a Baby Bird Makes Its Mother Abandon It

Animal lovers mean well, but this is pure fiction. Birds have a terrible sense of smell, so they won’t “smell human” on their chicks and reject them.

If you find a fallen baby bird, gently placing it back in its nest is fine.

Its parents won’t care. They’re just happy to get their screaming kid back.

Nature doesn’t hold grudges. It just wants peace and quiet.

Mount Everest Is the Tallest Mountain in the World

Depends on how you measure. Everest is the highest above sea level, but if you count from base to peak, Hawaii’s Mauna Kea is actually taller, most of it’s just underwater.

So yes, Everest is impressive, but technically it’s not the tallest mountain overall.

Your move, trivia night.

The Coriolis Effect Makes Toilets Flush Different Directions

Every American tourist loves bringing this up when traveling to Australia, but it’s not true.

The Coriolis effect influences large-scale weather patterns, not your bathroom plumbing.

Toilet design determines the swirl, not the hemisphere. So whether you’re in New York or Sydney, your flush direction depends on the manufacturer, not the planet’s spin.

The Earth’s rotation has bigger things to worry about.

The “Five-Second Rule” Keeps Food Safe

Drop your food and shout “Five-second rule!” all you want, it doesn’t protect you from bacteria. Contamination happens instantly.

Studies show that moisture, texture, and surface type determine how much bacteria transfers, not the timing.

So, that slice of pizza on your kitchen floor? Probably not fine.

Unless you’re really hungry. Then, you know… make peace with your choices.

Glass Is a Slow-Moving Liquid

Old windows are often thicker at the bottom, leading Americans to assume glass “flows” over time.

But glass is actually an amorphous solid. It doesn’t move like honey in slow motion.

The uneven thickness of ancient glass comes from how it was made, not physics. Medieval craftsmen just weren’t great at perfect panes.

So no, your windows aren’t slowly melting. You’re safe.

Ostriches Bury Their Heads in the Sand

Ostriches don’t actually do this, no matter how many cartoons say otherwise.

When they bend down to turn their eggs or look for food, it looks like they’re burying their heads.
