It sounds like such an incredible fact. “Our own cells are outnumbered by our microbes 10 to 1!” I don’t remember where I first heard it. But I read it in science papers and articles by journalists, so I believed it without question. I even made one of my first videos based on this fact. Problem is, this fact is not true. So how did it remain firmly planted in our common knowledge for almost four decades without any scientific scrutiny? And how can you prepare yourself to not be fooled by other scientific urban legends? I look at a few of the most famous incorrect factoids in science, and give a few suggestions for how to make our common knowledge more correct.

Awesome!
Which means we need to end capitalism, which is why most scientific knowledge is currently behind paywalls.
Nevermind that capitalism is why we have enough science for most of it to be behind paywalls. Modern research is frequently expensive, because while we can't ever say that we've absolutely discovered everything that can be discovered by a curious person in a home lab, we can say we reasonable confidence that we discovered a significant plurality of things that can be discovered that way.
Somebody has to fund further research, and the government only funds what will win votes, which these days mostly means high profile space exploration, green energy (without much regard to actual viability, I might add, just look at how much tax money has been poured into nuclear fusion with nothing to show for it), and the LHC.
Governments do make smaller investments in other fields, but on the whole those contributions are negligible compared to private sector spending/contributions that result from free market decisions. To abolish capitalism is therefore to abolish most science.
@@benjaminnelson5455 Name one thing besides useless pharmaceuticals being research by private funding. Almost all research is government funded. Try again.
Yeah, I had to screen-grab that one.
@@krellend20 Space Travel, particularly efforts to mine asteroids (with the goal of building a "2001" style gateway space station), and colonize Mars. Nasa has plans for the latter, but Blue Origin and especially SpaceX are years ahead of them. Just about anything related to computing, especially quantum computing and machine learning, all of the actually promising efforts to achieve practical nuclear fusion. All of the advances in self-driving vehicles. Most of the advancements in energy storage. Any advancement in civilian air travel, there's even talk of going supersonic again.
That's just off the top of my head, I'm sure I could write a longer list than most people are willing to read with a bit of research. Shall I continue?
I think a big reason kids seem hyperactive when they eat sugar is that they're often allowed (or encouraged) to eat sugar during times when they're going to be excited - holidays, parties, sports events, etc. - so they're acting energetic anyway.
kids are already wired for hyperactivity, and I truly never understood the ban on sugar. ir''s brain food,, quite literally. It doesn't cause diabetes, it doesn't burn holes in your clothes, and if kids seem super excited when you "'allow' them a candy cane once a year, that's because they arent used to the stuff and it probably wakes them up.
@@judythompson8227 Refined sugar is bad for you, period.
@@judythompson8227 Refined sugar does cause diabetes. IE it is likely to be turned into fat by your liver which then can cause your pancreas to be less effective at producing insulin.
@@gordonlawrence1448 Refined sugar doesn't have any vitamins/minerals/protein. It is just empty calories. It also gets absorbed quicker than starch and triggers the liver to overproduce insulin, causing a sugar spike then drop.
Sugar is fuel. You guys don't sound like parents. Predisposed or not, they burn sugar very efficient. I've told them it was diet and vice versa. It's true that they get excited when they get the sugar in their possession because sugar is a reward, but in event instance physical activity increases.

You forgot: "We only use 10% of our brain."
He was going for widely accepted and correct seeming facts, not ones that most people already don't believe.
It's true tho. We do only use a small percentage of our brain simultaneously, but not because it hasn't "unlocked" its full potential or anything. It's more for the same reason why we don't use all 6 gears in our cars simultaneously. It just doesn't make sense
@Mr Right The whole brain and the full potential are not the same thing. We use every region of our brains but that doesn't mean we use it to the full potential. Neuroscience is still in its infancy. There is a lot we don't understand about the brain.
That's because he was only using 10% of his brain when he didn't think of it.

My Dad, an aeronautical engineer, once pointed out how media outlets love to use the word "expert" when interviewing someone without providing evidence as to what makes that person an "expert." He also noted that the media loves to use the expression "numerous studies" when talking about how a certain conclusion was reached about something--without citing those "numerous" studies.
And they're not just experts, they're "top" experts.
@@CdnGeoff 👍😄
Gotta get tired of that. “Arguably one of the most xyz of his time”. The burden to meet that criteria is “at least one person can make the case that some person ranked >%50 of who ever happened to be involved in that activity the same day, month, year. They never say.
I recently had this with an "expert" on surgical intervention (read as dental patient unhappy with her dentists choice to use analgesia because she was scared) provide 10 medical abstracts that "agreed" with her statement despite not being peer reviewed. Now, I take issue with abstracts in general since they don't give the whole paper, you only see the hypothesis and the results they want you to see. I also disagree with 1 person providing me with the papers and telling me they must be right. Of course papers you give me will agree with your statement, you chose them. Why would you choose something that disagrees to prove your point?
"Expert opinion" is just that especially when you ignore opposing "expert opinion". An expert can be very wrong and are only right until they're challenged, it's how we make progress in our knowledge. We challenge known convention to prove or disprove the hypothesis.
According to the late Reg Smythe, an expert is someone who knows no more than you do, but is better at using diagrams.
What I’ve read about hyperactivity in kids is ... it’s not the sugar, it’s the environment. Kids commonly eat sugar when with friends, parties, Halloween, etc. These are events where they’re going to be all revved up anyway. Makes sense!
Love the video!
Agree that makes sense. But note that sugars, and most carbs, do get converted to energy (or if not needed at the moment, fat) fairly quickly, so people maybe sometimes feel a little boost of energy, then crash (that energy runs out). Also, something he didn't mention: sugar is addictive, especially in kids.

Regarding the part about losing 80% of your body heat through your head. My first scuba diving instructor said it perfectly. If you lost that much through your head in the winter all you would need to wear would be a hat.
But aint that the whole point of the claim? You should wear a hat in the winter, cause if ypu dont you can lose a suprising amount of heat and energy through your head. And therefore feel really cold in your whole body.
Everyone understand that how much heat you loose through a bodypart depend on what clothes you wear. But there is still a lot of people who dont wear hats in the winter and complain about how cold it is and that they need a thicker jacket.
The same goes for shooes/boots. Good, thick insulated boots have a huge impact. And the same rule apply for warm pants and scarf.
More generaly, you need to insulate your whole body. Else you might freeze, Even though you have a thick jacket/coat.
@@yvindharila8225 You still dont lose eighty percent of your bodies heat out of your head. Yes you lose heat and should weart a hat lol.. but you missed the point completely. And that is that you lose a hell of a lot more than twenty percent of your body heat out of your torso and extremities
Perhaps false in general, but that is my personal experience. Certain flavors light up in different parts of my mouth, including the palate
@@MrDiveDave People used to sleep with hats/night caps once upon a time in the winter for this very "fact."
@@ydad8946 Seriously? Have you ever heard of Dunning Kruger I have a feeling you're suffering from it. I'm a master scuba diver with over 15 different certifications a big part of that is learning where you lose your body heat in cold water. You do not lose 80% of your heat through your head. To even suggest that is absolutely ridiculous. It's better to be thought a fool than open your mouth and prove it.
This is the one thing my science training has taught me that I value more than anything else. If things you think you know aren’t supported by evidence or if new evidence is presented, there’s no shame in changing. Being wrong is fine. Continuing to be wrong in the face of new evidence isn’t. Changing your mind is a very good thing.

'A lie gets halfway around the world before truth puts on its boots'

This helped me figure out what to say to my mum about losing her faith, it’s nothing to be ashamed of, now we just replace the false information we spent years consuming and building as though it was a real knowledge base. Replace bad info with better info one day at a time. Thankyou
This is the saddest thing i've ever read. Spiritual faith is not about knowledge it's about morality and wisdom. If you're looking at the Bible, for example, for scientific knowledge, you're doing it wrong.
@Convoy00X Faith is the reason you give for believing something when you don't have a good reason.
I don’t think it is sad at all, religion is filled with belief and fear of nonsense. We can still be kind to each other without fear of an imaginary hell threat.
@@JohnKoenig-db8lk "Now faith is confidence in what we hope for and assurance about what we do not see." Hebrews 1:11.
Not having any faith is insane. You cannot exist in the world without believing into things you cannot check yourself, you have faith the food in store won't kill you,.for starters, people have faith in their spouses not cheating or end up calling them 40 times each day, you have to have faith in things you aren't checking yourself like government regulating traffic else you'd be a paranoid maniac.
@KasumiRINA There is a big difference between "faith" and reasonable expectations. "Faith" is the reason you give for believing something when you don't have a good reason. The ravings and fantasies of ignorant, bloodthirsty Bronze Age goat herders is not a good reason.

He got me at "what size of glasses even?" Cause ive been asking that my whole life too man
I asked someone (probably one of my teachers, but I don't remember) that question and was told that glass meant 8 fluid ounces in this context, but I bet that they either made that up or got that information from a chain that leads to a source that made it up.
@@88michaelandersen Eight fluid ounces is definitely not right, because the paper says 2.5 litres, which would be about 84 fluid ounces in total - just over ten per "glass".

@@KlaudiusL also not, because 2.5 liters would be 10 glasses of 250 cc in volume.
Ultimately it doesn't matter because so many people who tried this had to stop because it was making them feel sick.
For the hyper kids eating sugar thing - often when kids have had excessive amounts of sugar, this is usually at a special or fun occasion, like a birthday party, or a special treat to go to the park etc. So this is what has wound your kid up. Also the event of just getting some sweets, or chocolate may be pretty exciting too.
Also if you tell a kid "if you eat this it'll make you hyper" then they'll be extra susceptible to the power of suggestion.

As a dog trainer I learned the one about alpha male/female in reference to wolves and dogs.
A lot of misconceptions seem to originate from one person saying " I think it goes like this" and everyone else saying " That checks out, now I will defend it to the death!"
That's probably one of the most fascinating examples because so many people will die on that hill, despite the fact that the original researcher himself discredited his work saying the wolves were studied in captivity and not in natural family units (mostly young males) and once studied in nature those behaviors changed significantly.... so doesn't even apply to wolves.
I learned in school that the tongue has different taste zones, even though I was born 11 years after that myth was debunked. I believe that myth is still printed into biology school books today.

I remember learning this too. Though I always thought it didn't make sense because I would try to put food on different areas, but I could still taste it. Seems like a fairly straightforward thing to dismiss, surprised it became an idea at all.

Thank you for this outstanding video, it is going to become required viewing for all my students (grad and undergrad). As you probably realize, the problems you illustrate go way beyond having false opinions. I have seen false “facts” through citation inhibit research, delay genuine findings by years, and misdirect scientific investigations. Also, you focus on unintentional misinformation entering the literature, but both as a researcher and a subject editor for three journals over my career, I’ve seen lots of deliberate attempts to misinform, many of them successful. Like many, I am a critic of peer-review and the current (absurd) scientific publication system (the public pays for research, but private publishers control access to results), but almost no one outside “the business” realizes the damage being done. So again, thanks for your work in public education, as you did here, it is essential.

shaving doesn't make hair growing faster or thicker
Julien Ribollet explain.
Here’s the thing, I tried to prove this ... by using my own damn body, which I deeply regret. Like 2 years ago I was in the shower and I had the smart idea to test this and shaved the area around my bellybutton, which at the time, looked completely hairless. A couple weeks later hairs were clearly noticeable ... and so every summer I have to shave my stomach. My stomach. They are thick and long as hell. The rest of myself is completely normal.
So that’s why that one area in my stomach is hairy and the rest are not...
What makes you call this a myth?
@@illusionfaderr5394 The same thing happened to me. I feel like hair regrowth must vary person to person and body part to body part.
Your hair is cone-shaped like ,so if you shave the top you get the base of the cone

Absolutely love the final lesson. Be humble enough question your own understanding and be open to new understanding. And how accurate knowledge, education, and understanding should be more readily available and accessable. I understand that a lot of effort, time, and money goes in to conducting and publishing studies, but there has to be a better way. Hopefully that will happen sooner then later

Great English. Too bad about the "then" misplacement.
"Than" is a comparative.
"Then" is a time reference
One of those myths is "we use 10 or 25 percent of our brains"
that's true, i don't even use 1% of my brain
That's more of a common myth that doesn't even pass a basic "smell test." The ones in the video went through peer-review.
I know people who would be greatly improved if they did.
Isn't that just worded wrong that made it a myth? Like people thought it meant that we use ONLY 10 or 25% of our brains, but it's actually we use 100% of our brains, but only 10 of 25%of it at one time?
I don't even know if that's true. I read it somewhere. Maybe it's just more of the same myth.
@@IntergalacticSpaceKitten It is a variant of the same myth. I can not quote the source but if memory serves ( as always if you want the truth you have to spend time to look it up or hope someone like the creators of this content do so for you ) is that it's based on the percentage of the brain involved in cognitive behavior. Which I believe is about 10% of total brain mass. Somehow that got translated into the idea we only use 10%. Which then got refuted by other studies leading to confusion on what percentage is involved hence the 10 to 25 percent numbers.
In fact, all parts of the brain capable of functions do so all the time. Only in damaged brains is there a loss of function. So we use 100% of the brain. Now, how much of that is cognitive is subject to debate. Even if that's our total brain power is subject to debate. Grey matter can be found at the base of fingertips and along the spinal cord. And I am sure you have heard of muscle memory ( most likely linked to the Fascia). Also the brain gut interface affects brain function. All this leads to the possibility that the brain doesn't actually include all of our " processing " ability to begin with and that there may be more to this story. I used the term processing because most of this is not anything we are aware of but is necessary for life anyway. Sort of like a computer were we see the " interfaces " but the real machinery isn't actually any part of that interface. It's only the surface we can relate to. In many ways, the story of the human brain is the same. We are only aware of our conscious interface and miss everything else below the surface.
------
There is nothing more difficult in science then using a organ we don't understand to figure out that same organ. Brain studies often quote this in one form or another and this myth points to the root of why that is so true even today.

In my M.Sc. thesis in biomedical engineering I was asked to provide a citation for what Brownian motion is, so I did cite Einstein's 1905 paper (and for fun, I also cited Brown's original 1827 paper, but decided against citing Lucretius' "On the Nature of Things", c. 60 BC, because while he describes Brownian motion, the example he used was not due to Brownian motion).

"the only good germ is a dead germ" has sold the consumer a LOT of antibacterial products, and no one ever seems to get beyond the idea that the bacteria that lives on our skin is what protects us from the bad bacteria when we get a cut, a scrape, or even a blister. If you douse yourself in antibacterial soap you have effectively killed off all the good guys that are there protecting you. And once you start using it, you will have to use it forever. It takes at least two to three weeks to let your body regrow the good bacteria again. It's happened to me twice, and not again.

10:10 Actually that's a myth, too. You can just email the scientists who wrote the papers, most of them will gladly send you a free copy because they want their work read and they hate paywalls too.
Right, but that's time consuming and the casual reader, that is, someone just looking into learning new facts as opposed to someone writing a term paper or doing background research will not pursue this strategy. (TMT = Too Much Trouble)
Coming from my Ph.D. experience, this is true! This might not work for older papers since authors change occupations or retire, or just don't answer.. Having open-source papers would be more reliable
There is also arxiv these days though, I hope it will be used more widely =)
Thats true but it is legally debatable. The editors OWN the paper. To distribute it without permission is kinda of a crime (yes, even the author). It's like saying: you don't need to pay to watch films Because you can find them on the internet.
@@azielmelo7756 First of all, the author owns it, not the editors or publishers. That's how copyright works. Second, even if you were right on that point, they're not making any money handing it out for free, so there's no copyright violation and thus no law being broken.
@@azielmelo7756 An author distributing something that they themselves wrote is not even remotely close to being the same as piracy. Because they wrote the thing and so they hold the copyright on it.

The percentage body heat loss from the head myth comes from a military study for their arctic gear which showed that with the face exposed (if I recall correctly) 90% of body heat loss was through the head.

Well, joke aside, research results not available for free is because research needs money to be done. If scientists give the information they bleed to research willy nilly, from where they get money for next research? And ppl with money wont throw their money at research that dont benefit them.

If you want people (as in private investors) to pay for your research you'd rather get a patent.

I've been told my whole life to never cite Wikipedia, and I only got a good reason for it in uni: basically, you should never cite secondary sources.
If you are going to adhere to that rule thou, probably also shouldn't cite articles or talks where people try to summarize research (i.e. any "according to some study, ...").
For every day use, I'd say wikipedia is one of the best things to cite, if only because most articles are well cited, and usually to primary sources. So if something seems weird/counter intuitive, it will be easy to check.
Ofc don't cite a wiki article that has no citation itself. Then it might as well be a blog post.

While I'm not a huge Wikipedia reader anymore (and I do know for a fact there are many unreliable claims), it's an excellent place to start learning about a topic. Many times your knowledge about a topic is so low you don't know where to start, or even what questions you should be asking to learn. Wikipedia can help you with that.
Check out the cited sources at the bottom of the articles for more in depth and/or more accurate information.
This helps to determine whether the sources are accurate to begin with and gives a chance to find more sources of information on topics you're interested in.

Fun fact about the sugar-kids one. Growing up as a French kid, I had never heard that sugar made kids excited, I discovered that idea as an adult in American TV shows. I took it for granted and was surprised we didn't learn it here...
Hmmm, I'm from the Netherlands and definitely know some people who grew up believing this (not being allowed sugar, or only a little by their parents). But when my 60 year old was a young kid it was believed it was healthy to give kids a cube of sugar. I guess a lot has to do with your close surroundings and if you were a busy kid or not
I also learned that in Cartoon Network
I had a teacher in High School who was still actively perpetuating the "Blood is blue when not exposed to oxygen" bullshit. They were a PE teacher who also taught a "Health" class. That was only the tip of the iceberg in that class though. It was a wild place.
why are PE teachers always the thickest of the bunch. mine once told us that soft drinks made kids gay. that was a straight insult to my face.
That’s a myth too? Man idk what to believe anymore 😂
@@liverpool0690 yep! red blood cells contain a protein called hemoglobin. the hemoglobin then has heme, a red-pigmented compound. these are what allow RBCs to transport oxygen, and also what gives them the red color!
also, veins appearing blue is kind of like a visual illusion. blue light can't penetrate our skin very well, so it'll reflect off the veins close to the surface. which makes them *look* blue, but they aren't *actually* blue.

I can recall when I was in high school one of my teachers wanted me to do a report on the health benefits of positive ions. I could not find one single publication that flat out said that exposure to positive ions was good for us. I found plenty of information saying that exposure to any form of free ions was in fact really bad for us. And those ion generators that used to be so popular, they produce O-zone which is even worse for us.
Your cellular respiration handles its own regulation of ions so unless you have an access from say, static cling, there is no benefit to adding radicals.
I've never heard of positive ions being good for us, but there's a widespread belief that negative ions are good for us.
there's a veritasium video about this, i think it's called "do salt lamps work?"

3:25 'a good reminder that a good story is not necessarily a true story', I liked that.
we need a field of science dedicated to checking for these types of errors.
This video perfectly encapsulating what is wrong with all media. Do your research. Trust none of what you read or hear. Well done on the details
One of the biggest problems are people quoting non-peer reviews science journals. One guy did a study to see how fake information could be passed on as true scientific information. One step was to publish his fake information in a non-peer reviewed journal, then it got picked up by “reporters” that don’t bother checking sources and it got passed along social media as true so much so that some tv stations picked up the story.
this reminds me of the "you swallow 8 spiders a year in your sleep" factoid that was purely a troll meme back from before the internet existed.
Not only is scientific knowladge difficult to obtain, but it's difficult to understand without learning how to digest it. On top of that a lot of people release "scientific articles" that sound scientific, are easy to read, easily accessible, and very unscientific and not factual
Actually, all those things behind paywalls, it's actually perfectly acceptable to email the author directly. And the author is legally allowed to send you a copy of their research, free of charge, or so I hear. If nothing else, it's worth asking, right?
How can we "fight" this?
@@llearch yeah, true. But usually, you'll have to have a reason for him to actually send it to you.

This is your best video I’ve seen to date. Keep it up!
Why? Because it’s about the importance of the scientific PROCESS, rather than merely the scientific results…
On top of the journals hiding research behind a pay wall, 100% of that money goes to the journals, not the scientists. The researchers who write those papers see no money from their published papers. We don't get royalties like you would if you published a novel. So if you email one of the authors of a paper you want to read, most times we'll just send you a copy.

I always thought the 8 glasses of water a day seemed like a lot of water. I usually drink between a liter and 2.5 liters of water a day, depending on however thirsty I feel. It makes me wonder what percent of my water intake I am actually getting from foods
I recently heard 8 CUPS a day, which I thought was more reasonalble and thought maybe I'd been misunderstanding all these years
I make to sure to drink at least 9-10 glasses of water everyday, well at least 95% of it or so is anyways.
I've heard the 8 glasses to be 2 litres of water, but in recent years, I've heard it modified to say 2 litres of liquid, including the liquid from food.
I go to the sauna a lot & when I do, I easily drink that much, often more like 3-4 litres of water in a day. I have issues with low potassium that doctors think may be from drinking too much water. I only drink the amount I want, I don't force myself at all, I just crave it when sweating

In general, *none* of the money from the paywalls goes to the authors. It's pretty common to have to pay "page charges" in order to publish.
I read that you can usually just email papers' authors to ask them for a copy of their papers. They usually get absolutely nothing from the paywall sites and are happy someone's reading their work
Yep. I've done this a number of times. And they are usually happy to oblige.
@@Ella_Roland Usually you can just google them to find out where they work. Then once you know that, you're just another google away from finding their email.
