That there are magic pills that make you lose weight and gain muscle without ever going to a gym. Or that there are snake oils that will take years off of your face and make you look young. There's a sucker born every minute.

That there are dozens of hot singles in my area just dying to meet me.

Fish only have a 5 second memory. My fish are fed automatically on a timer and they know dinner time better than my goddamn cat

I still believe that if any of my limbs hang off the bed while sleeping that a monster will grab them. I also believe that the moment I remember this and pull them back on the bed is just in the nick of time before a monster grabs them. You can't prove there isn't a monster under my bed.

Trickle down economics.

Tear here to open.

That humans only use 10% of their brain. This is false, regardless of how those who proclaim this myth seemingly demonstrate that it is in fact true.

The whole “Alpha/Beta male” thing

That you eat spiders in your sleep. Spider will not knowingly walk into a predator's mouth. They can sense both the heartbeat, heat and noise from humans. All things that would alert them not to go into our mouth.

At some point, a viral video allegedly proved that the “beg buttons” at crosswalks are just placebos. Some of them are, but most of them really do add a cycle for pedestrians to get a walk signal. You should use them regardless

Religion imo

When I had cancer a few years back and was doing chemotherapy I had people who constantly questioned that I actually "had cancer" due to the fact that my hair didn't fall out until I was actually in remission (Had been off chemo for about 2-3 weeks when my hair started gradually thinning and falling out). It's a complete myth that every single person's hair will have the same reaction to chemo. Some people lose hair right away, some don't. Everybody is different.

"Lie detectors" as a literal thing. There's a reason they aren't admissible as evidence in court in most places.

“Lightning never strikes the same place twice.” Yes it does, that’s the entire reason for lightning rods on buildings.

Life is fair, and bad things only happen to people who deserve it.

There are dumber ones out there, but the one I, as an estate lawyer, deal with constantly is the idea that there needs to be a "reading" of the will, where the family all gather and the lawyer reads it aloud to them for the first time. We don't do that, we just mail everyone their own copy if they want it. It's a really stubbornly persistent one because people continue to see scenes of it in movies and TV shows, where it's used for some big dramatic reveal. I've even had irate beneficiaries insist that the administration of the estate can't be "official" until there's a reading. Way, *way* back, like 150 years ago or so, I believe we used to do something like that at times because you couldn't exactly presume literacy on the part of the beneficiaries, but now we feel it's a pretty safe bet that you can either read it or find someone who can.

That Einstein failed his grade school math class. It was the subject of a Ripley’s Believe It or Not column in 1935 and Einstein himself refuted the article. In primary school he had been at the top of class and by 15 he had mastered differential and integral calculus.

Halloween candy is commonly laced with [illegal substances] or razor blades.

You have to wait 48 hours to report someone missing

Anything about MSG. I battle with my health conscious wife about this often.

Corporations care or even exist for any reason other than to make money.

I remember the myth that gum takes 7 YEARS to fully pass through your digestive system

That you can write a comment 36 minutes after the post has been made and believe that it will gain any sort of traction

Still blows my mind that people think the Earth is flat.

It is believed in Indian culture that keeping your unibrow means “good luck” I kept my unibrow for 20 years thinking it is my “good luck” until I got stage 5th of kidney failure and I did my eyebrows after that because who gives a f**k about luck anymore. Now my eyebrows look cute af.

That the underdogs are: always good; always right.

"Oh, I don't want a raise/make more money, because then I'll lose more money to taxes and take home less!" You only get taxed on the money that's made above your current bracket. Its literally impossible to make more money and take home less.

That magnetic jewelry / healing will cure just about anything. A dude named Mesmer the 1780 came up with the idea, and it have been debunked many times - yet it’s still a billion dollar industry. Fun fact - the word “mesmerized” is related to him.

Had a cab driver insisting that the reactor meltdown at Fukushima was a failed Chinese attack on the US. The plan was to superheat the rods so they'd burn into the ground, through the center of the Earth, and come out in America and irradiate it. Amazing.

So many people think Narwhals are mythical. A more serious one, that people who have been hurt or oppressed are morally better. My Mom thought that because she had been hurt by her Dad, whatever she did to the family was somehow justified. The Hutus were legitimately oppressed by the Tutsis (but to be fair, that comes back to Leopold, the patron satan of Africa). All people are fundamentally similar.

There are still people who believe that having [making love] in certain positions or eating certain foods can influence the sex of your unborn child or impact whether you have twins/multiples.

My dad had this guy helping him out (think Big Box store DIY curb ready helper) who told him "If you sleep with your hair wet, you will bleed out of your mouth"... and he was 110% sure that was fact. We were both just confused and bewildered at this statement. What the hell had this guy witnessed?!

Had to explain to a grown a*s adult that blood isn’t blue inside the body and red once it hits oxygen because… blood already carries oxygen.

Headlights off at night is a gang-banger initiation rite. So, don't flash your lights at them.
