The most surprising thing to me is how many of these myths originated back in the 1800s! Why are they still being spread today?!?!? It’s remarkable how out of touch we can be and how easily it can happen.
@@adamadam367 before newton proved that gravity is real it was considered as a myth. The Greeks created the concept of gravity and levity, and no one thought of it as real aside from ancient Greeks until newton has proven it to be real.
that's because there isn't anything better to replace it... such as the IQ test, it's still the best predictor for future financial success and longer life
My wonderful mom has always said that “everyone is smart in their own way,” as Dr. Kamitaki also so empathetically expressed, and in my 43 years of life I’ve seen this to be *so true*! There are so many ways in which a person can be talented and brilliant if we just look for it and appreciate it!
Yes! I've been an advocate of this perspective for as long as I've understood it, and the evidence is everywhere. We are remarkably resilient. Just look at the amazing things people with "disabilities" can do, or how the brain adapts when a part of it is damaged!
I have epilepsy and I can confirm how important it is to take medication and see your neurologist at least once a year. Everytime I have a tonic clonic seizure, I always call my neurologist to let him know.
I want everybody to know that as soon as the left versus right brain myth was debunked in this video I got an ad for Twix, saying it doesn’t matter if it’s the left or right. I was PROFOUNDLY confused bc I was merely listening to this, so I didn’t see that it had changed. It was a supremely jarring experience. Kinda terrifying, actually.
The IQ one has always bothered me. I am a "gifted" person with ADHD. While I ranked above average in IQ tests, I struggle to function because simple tasks like doing laundry and remembering appointments are incredibly daunting. It's like whoever chose my stats had a really fucked up sense of priorities
Same here x-x And then there's the "If they would only apply themselves more since they're so bright" and all that stuff. I mean, yeah. Like Dr. Barkley said, though; we know what to do, but can't do what we know D: That pretty much nails it for me, usually.
Man, now you've got me curious. A few months ago I I tried getting tested for ADHD and the phsicologicst argued in the results that it was negative since wasn't possible because I had an IQ above average
Your Doctor is clearly a fraud. I scored top of my classes for everything involving numbers, be it Physics, Chemistry, Computer programming etc. I was diagnosed at age 6. And I also struggle to keep simple things like a simple schedule or properly finish a task when distracted in any way.@@Eye-Of-The-Beholder
Thanks for debunking the myth about male/logical female/emotional myth. I'm a woman and I can think pretty rationally when I need to. The only thing I become emotional over is cats, but it's a luxury I allow myself.
So true, I'm a woman n I'm less emotional than normal people (at first I didn't realize it but then many people told me, so..). My husband even more emotional than me. Haha. Be
IQ is kinda like horsepower. Even if you have high horsepower, if you have poor grip, down force, high weight, poor aerodynamic, your car is still gonna be slow as hell😂
IQ is not fixed though, continuous education can increase a person's IQ It's silly to want to believe that a kid after pre-school taking an IQ test would score the same if they take it after college. Especially looking at the IQ tests which use specific formula that you can sorta train to discover, but also, you can generally train your brain to take tests better by taking tests over and over again.
Pretty sh## argument. iQ is not horsepower. You dont go around killing people like a car running over people. If you have High IQ just because u lack grip, down force etc etc. Usually IQ stands to denote how fast you understand certain things if not most things, a HIGH IQ individual is less prone to anxiety, erratic behavior and understand what most people don't around him if 100 people have 100 IQ and 1 individual comes with 120, he will certainly have higher Odds of becoming their leader if these 100 men have 120 IQ then a men with an IQ of 140 would be able to stand out. Its always ALWAYS gonna be a factor of genetic mutation as well as environment factors. People who strive to do something else and unique entirely will have higher probability to have high or better IQ then rest of the people/most of the people.
@FredCarpenter-vv9ld Assuming they have the correct answers, you can definitely train yourself to get better scores with similar styled questions. The problem with IQ tests online is that if a person takes it, they have no idea if they got a question right or wrong. So there is no way to review the answers to their questions. Hence, you can keep making the same mistakes over and over again. So, if you taught your cousin some of the solutions to questions you know they have no idea on how to solve, I'm thinking they might get higher results the next time they take the quiz.
Ok so on the subject of IQ tests, I have an 11 year old son with global developmental delays, he can't read or write yet, but boy, he can tell you about a LOT of things, and in great detail! Unfortunately this world is based on paper and ink, so to speak, so people like my son are considered intellectually disabled, but that's just not true, my son is very intelligent, so who cares if he can't write it down or read it? There's videos on literally everything these days, and literally everyone has different ways of learning and communicating, so why are we still measuring a person's intelligence by literacy alone? It doesn't make sense.
I agree! We can't judge people just because their head is smaller/bigger or if they play basketball then it would depend on their height. Nah skills matter, it's the development. If you're not good at one then you're good at another. I actually think people who have disabilities like adhd or autistic could be great at certain other things than normal people.
@@exp-io853 oh yes, people on the autism spectrum, I know because myself and all 3 of my children are on it, are highly intelligent, my middle child has ADHD, and is extremely intelligent, but just isn't capable of focusing for long enough, especially on subjects that bore them to death! We're so incredibly grateful that their school has based their ILP on their interests, such as anime and manga, because otherwise they'd literally have no chance in hell of passing school! As it is, they will spend hours doing English and Art, but Math... they're so good at it that it's boring, it's not challenging at all, they absolutely hate it, but they need it to pass!
I recently read somewhere that a lot of CEOs/Higher level executives are dyslexic ( I'm not presuming your son is dyslexic by any means) because dyslexic persons tend to have good verbal communication, delegating and social skills, and excellent memory. Goes on to prove that there is many different ways of being "intelligent" and being not so good at certain things traditionally associated with higher intelligence doesn't mean anything any more. With sufficient technical and emotional support, learning "disabilities" should not affect the quality of life and opportunities.
I love your mindset and perception your son will become a good human rather than a highly educated inteligent rat like this shitty world asking for. Save him and make him a good human. 💙
I’ve been an RN for almost 30yrs & the stuff I learn about brains has changed so much since I was new. We’ve learned SO much but still some things we just shrug & say “i don’t know. Brains are weird.” Also, does being ambidextrous change how one’s brain reacts? (As opposed to be left or right-handed?) just curious.
As an ambi', myself, I'm gonna have to say there's going to be a lot of "It depends" for that question... I was born "left handed" and ended up LEARNING ambidexterity to get through life easier. My mother (God bless her) was a staunch supporter of the idea of "Never tell that boy he can't do something that way." SO the teachers at school got backed off when I picked up the right handed scissors (or the left handed ones) or any other utensils simply because they were in better shape and more available than the ones for my "handedness"... Part of the "trouble" with ambi' is that I lose some of the sense of "right and left" orientation, because there's less influence on the cues for it. I had to just memorize it, where the "normal" person bases it on which hand they write with... AND the other direction is just the opposite... BUT I didn't get so much of that. Sometimes I write with one hand, but when it gets tired or I just don't feel it, I'm working with the other one... haha... The "advantage", however, is that I'm not so limited. Having learned to do things with both hands, relatively equally well, while it's taken me just a little longer to develop that "hand-eye coordination", now that I've got it, I'm generally more intimately involved in any skills with my hands... Being able to carry on a task when one hand gets tired, simply changing the duties assigned to the hands, DOES give me more "range" or "endurance" for it, and that adds to productivity... AND if I injure a hand, well, the other has less trouble taking up the slack, so to speak. I'm just a little bit less inconvenienced... and you might be surprised at how aggravating life can get when the hand you USUALLY wipe your butt with doesn't work well enough to do the job. (lolz) Someone who was just naturally ambidextrous might have developed their "hand-eye coordination" faster than me and not suffered nearly the disadvantages of putting up with dull scissors or trying to negotiate Caligraphy with the screwed-up "bent" pens... Switch-hitters in baseball tend to be prized by teams, making that bar of performance just a little lower than maybe the rest of the players, whether orthodox or "south paw". AND A LOT of it's going to depend on the culture they were raised in, and their parents and general "support" for it. Some cultures still stigmatize left-handedness as "of the devil" so there can be dubious mistrust and outright abusive tendencies for such a little detail. That can stunt the skills with the left hand, and diminish their appreciation of a talent... just as much as quietly practicing on its own can be a great benefit, building the neural pathways and creating more dynamic flexibility in a person's dexterity overall. IN ANY CASE, I hope this helps a little bit. I'm no pro' about neurology, of course... JUST a perspective that might offer even some subjective information about how life is experienced, and the evidence (as I have anyways) that suggests there most certainly IS some difference in brain development between right handed or left handed folks and ambidextrous folks. I DO still have a dominant eye (my right one)... BUT just about everyone has one side of their binary systems (the organs and nerve nets in pairs) that's got a little shorter pathway to the brain and a little faster impulse travel, a little more dominantly reliable than the other... That's probably normal even for the most ambidextrous among us. ;o)

From what I’ve read, most parts of the brains do not make new brain cells, but neurogenesis does occur in the hippocampus and glial cells are possibly able to thicken or regrow as well. Just wondered about that since I often heard that it’s a myth that we only have a finite number of brain cells after we become adults. They stated that myth at the very end of the video.
Neurogenesis in adulthood has been observed in 2 regions of the brain ( the Dentate Gyrus in the Hippocampus and the Sub Ventricular Zone of the lateral ventricles) in mice. In humans, it has been proven only in the Dentate Gyrus and the investigations regarding Neurogenesis in the lateral ventricles are still ongoing. Therefore, we don't have a finite number of neurons. However, Neurogenesis in the above mentioned regions does slow down as we grow older.
When you exercise growth factors are released in the brain that can help to possibly grow the areas you mentioned. The other areas are set in stone I think.
I did the high school test without food and drinks after a military exercise where we didn't get to sleep a lot. Without preparation, once. Definitely noticed a difference. Everyone is dumb as a rock if they are tired enough.
@@ewdtrey Yeah, then eventually on drugs, as you start hallucinating as your brain tries to access dream sleep while you are conscious. Or so I've heard.
I have a couple of childhood friends who became eminent neurologists specializing in clinical cognitive research. While I have consistently scored exceptionally high in a series of government administered I.Q. tests, both of them have long been assuring me that I’m spectacularly stupid.
Well IQ versus EQ and social intelligence. And that's just 3 of many. They must be referring to something else X'D That said though, are they truly in a place to evaluate you properly if that's their way of treating you? Maybe THEIR EQs are too low to comprehend you. We'll never know! LOL
This was woke bllsht. IQ tests are the best thing and these people are 'debunking' it. Clowns. Anyone who parades social intelligence or emotional intelligence is a hack
That's because other equally qualified psychologists or neurologists can give you the opposite opinion. They look and read the same papers but come to different conclusions.
School staff made a big enough deal about my measured 1Q that my parents made big changes in my life. I realize the doctors put IQ test numbers in the appropriate place because people can have many skills and abilities those tests don’t measure. For me, however, my childhood and the peaks of my life have been highlighted my verbal ability and executive functioning. Lives can be significantly influenced by the experiences and opportunities given to a child. If you are young, try all the good things. You might find an extraordinary version of yourself no one yet sees.
7:00 one key thing about memory problems they forgot to mention is how certain chemicals can cause them. Household paint without ventilation, spray paint or stroke paint either way, is highly toxic. Same thing with glue, solvents, degreasers. You can use these chemicals just make sure to do so with ventilation and protection.
Lol, the size of the brain myth has always made me chuckle. Saying someone/thing is smarter because of a larger brain, is like saying a giraffe would be better at basketball than a primate, because it is taller. 😏
@@shadmansudipto7287 in the video, they compare brain sizes in different species (chimpanzees are used as one example). And in ours, height helps in basketball, but skill will beat it. Just like any other attribute, the key is development.
@@rolmodel12. my point is, there is not enough research to say that brain size doesn't matter. The people in this video speak too confidently expecting us to not fact check unlike the people from the other videos of this kind.
When I was 13 I was diagnosed with Asperger's. This was in '08, before they redid the ASD to the 3 levels they are now. I scored a 145 on the IQ test I was given at that time. It was not until 12 years later when I was 25 that I found out I have Aphantasia. MOST people with Aphantasia have no idea they have it. I just thought that when people were saying to "imagine" they were only using a method like an analogy or metaphor, not that they LITERALY meant to picture something. I think this makes the test I took very flawed. I can remember there being a good portion involving mental assembly of shapes into a final form. I don't think Aphantasia has influenced my logical or academic intelligence, but my social instead. I have a really hard time relating to people. Empathy and sympathy are not in my head a bit. It's hard for me to relate my own experiences with others, since my recall is mostly like reading a script. Things just exist as a list of details in my brain, but obviously not a visual. I have inner voice. Some info I just know and don't try to recall, it just happens. I am also completely ambidextrous. I will grab a writing utensil and use it with whatever hand is closer to it, without thinking about it, and make the same poor quality penmanship.
Most people with epilepsy can be treated with medication, but there are some instances where medication is not a viable option and people are able to manage seizures better through dietary changes/regulation and/or surgical intervention.
And some people diss the dietary treatment, but it's REALLY effective in a lot of people. The issue is sticking to it for long periods of time, because the low carb diets can wreck your body.
IQ presupposes that the best way to measure intelligence is by testing an individuals pattern recognition aptitude because it is the closest synthetic analog for learning problem solving skills. That makes IQ scores an excellent predictor for aptitude in STEM fields and technical employment. However it is not an effective predictor of aptitude for creative or interpersonal skills, which are equally as important for personal success in life.
One thing I've always wondered is, since our eyes are at the front of our heads - as it is in most species with eyes - why is the sight processing part of our brain located at the back? You'd think it would be at the front closer to the eyes. Also, how did the whole left side controls right side of body and vice versa come about? That seems like a very strange layout too.
I also thought about this strange positioning of visual cortex when they mentioned it in the video. The answer lies probably in how the parts of brain evolved over the course of primate origin.
Optic nerve as it traverses the brain has projections into the temporal and parietal lobe which also processes the optic signal and final image is formed in the occipital cortex. About the contra lateral control, it's because many nerves crosses to the other side either in the brain stem or the spinal cord. It's most likely because of something called somatic twist that occurred in vertebrates during the course of evolution. Invertebrates don't show this anatomy.
I think because of the complexity and the success of life on Earth, people gain the idea that all life is optimised and designed almost perfectly but there are a lot of flaws and pointless waste of resources. A few examples of these unintelligent designs: giraffe’s laryngeal nerve is much longer than it needs to be, human hips and birthing canal are narrow causing birthing to be dangerous and painful and tasmanian devils’ have 4 nipples yet have a litter as large as 30 resulting in very few surviving. These are just a few examples but every species has at least a few flaws in their design. My point was that there isn’t a good reason for it, its something that didn’t create a big enough disadvantage during our development as a species to evolve
@@kripa2982 also the optic nerves pass and cross (optic chiasma) in the thalamus and above the hypothalamus where it transmits information about the light conditions. With that information the hypophysis can regulate the circadian rhythm via the release of serotonin or melatonin hormones
the videogame thing is so true. There's obviously trash in all entertainment and videogames are no exception, some really do feel like they're slowly strangling each of my neurons, but I've found that games like Snowrunner really make you think logically and do a lot of risk vs reward calculation, throwing in variables like your vehicle's capability or potential obstacles on the road. Same as sim or sim-adjacent racing videogames, you have to be aware of your own capability as a driver, your car's capability, your tyre wear, changing weather if it's a feature, strategy, other drivers...Videogames really do give you hand on experience to form connections regarding quick decision making, strategy and risk vs reward thinking that a book, a school lesson or a documentary can't teach you, specially for younger kids that can't get into IRL situations that build those connections.
I can't see how that could be the case without some kind of definition of "intelligence" that would have to be designed for it to be true, somehow, and yet it's hard to imagine what it could be to be minimally valid. The best I could come up with is that perhaps by some neural correlates of intelligence, chimps' neurons are just as good, or some intelligence-related tasks. Chimps were actually found to have a significantly better working-memory than humans, and that's key for human intelligence (or highly correlated to IQ), but that's obviously not enough for human-like intelligence.
Pretty rich that neurologists are speaking about psychology topics as if they are experts. I understand that to the layman it may seem as though they should know a lot about psychology, and therefore IQ, but these are really two very different fields. Neurology is all about the physiology of the brain. While physiology can certainly affect cognition, neurologists aren't the ones measuring that. If a neurologist's patient is having cognitive issues, they may image the brain and run various tests to look for abnormalities, but how do they measure any potential cognitive deficits? That's right. They refer them to a psychologist to take an IQ test. This really turned me off from this channel as a whole. It's a real problem when experts pretend to be an authority on things they're not because the general public will just eat it up without question. I probably learned more about IQ in my one semester of cognitive science in undergrad than these guys did throughout their entire academic career. It just isn't a focal point of neurology.
Also, brain size does matter. It's just not the most important factor by a long shot, but it does likely matter. It's just that other things that make up the structure of the brain are believed to contribute much more to our intelligence such as cortical thickness. Brain size has a positive correlation (though admittedly weak) of 0.3-0.4 out of a possible 1 to intellectual capability. Having a larger brain than Steve doesn't mean you are smarter than Steve, but if your brain is significantly larger or smaller then it might be a good indicator of something. You just can't compare size when making interspecies comparisons due to the aforementioned structural features of the brain that we now believe contribute the most to our intelligence. What's even more hilarious about this video is her example of the bear. Bears have significantly smaller brains than humans. It's not just the size of the animal that determines the size of the brain like she tries to claim. Many large animals have very tiny brains proportional to their body mass and this data is easily found in a google search. Embarrassing! Humans have one of the highest brain to body mass proportions. I seriously doubt it's mere coincidence that the animals in which we've observed the most intelligence behaviors also seem to share this high ratio of brain to body mass (dolphins, whales, elephants). I would hate to have this lady as my neurologist. Did she even pay attention in class? What is even going on here?
@@philj9594ooo my dude you sound so weirdly narcissistic. “My field this blah blah blah> Drs and I’ll prove it by saying a lot but really nothing at the same time!!” You mad they didn’t call you for the episode?
Fascinating, I have always said IQ tests education not intelligence & I was right, I scored a very high score on the IQ test but in the midst of it I realized this is not testing my intelligence at all, because if I could not read I could not take the test, being able to read does not test instinctual intelligence, because you have to be taught to read no one is born knowing how to read.
@Rick Vis some learning disabilities exist and some kids learn differently doesn't mean they've got a lower IQ and I've seen some kids who had a lot of trouble learning in elementary school but as they grew older their acedamic performances became average.
That is asinine. If you are able to take the test it tests intelligence. IQ tests measure problem solving skills and education plays a miniscule part of it. That is why a highly educated person can score worse than an uneducated person
When i feel useless because im not talented at sport like my classmates were i remember my costumes and props ive made 😊 "no one can do everything but everyone can do something" - fav quote from a poster in high school
First of all I have two things to state: 1.Amazing video, i have definitely learnt a lot 2.I am having a doubt depending on the part where the dominant hand indicates the kind of person you are. So what if you wrote with both hands since your childhood or learnt to write with the non dominant hand later in life
A tendency is not a solid rule and doesn't determine things. There was a correlation found between brain activity and hand dominance. As they stated, none of this determines what kind of person you are.
IQ tests measure a number of different mechanisms for your intelligence, and even the primary determination of how fast someone can spot and process patterns is very valuable data, not to mention IQ is highly correlated with many outcomes in life. Just because we found some more nuances to define doesn’t mean we need to throw it out completely.
IQ is pretty stupid honestly. There is no such thing as being “smart” in order to be the definition of smart that everyone thinks would be to literally be at least intermediate in almost every subject math, science, history you name it. It doesn’t matter if you went to high school or whatever. You can still be dumber than a rock and I know this because I have met people who went to good schools and can’t even tell you how to toast bread. Sure IQ tests test pattern recognition but not common sense and really general knowledge. To live in this world you need to have common sense the basics of math history and science and you need some creativity as well. Someone can score good on an IQ test but they couldn’t tell you how grammar works or what the mitochondria is.
It is the most robust and reliable psychometric measure that psychology has ever produced, but yet many researchers are not a fan of it. I think a lot of that dislike stems from the implications of IQ as a very stable and robust measure of intelligence. Research (and this is actually some of the small fraction of social science research that is reproducible) shows that you can keep a high IQ child down with bad education, bad nutrition, bad parenting, etc, but you can't make a low IQ child high IQ via optimal condition, speaking to a reality where individuals have more of an IQ potential that differs from others. That is a very uncomfortable position to be in for a psychologist or someone working with social science, because the deterministic nature of it means that some people are simply destined to not achieve certain things in life.
You two should look up Kim Peek. That man was capable of accurately recalling the entire contents of over 12,000 books. He was capable of quickly calculating the day of the week that you were born just based on the date you gave him. He's widely known as the "Rain Man," the man with an incredible brain. His IQ was 87. I think that should speak for itself.
@@devinmes1868 IQ is a predictor of success, it's not a predictor of how fast you calculate or remember books. The strength of IQ lies in that it correlates reliably well with income, product sales, academic papers published, albums sold, bestseller books published, etc. And also that it speaks to a general intelligence, rather than multiple intelligences. For example, high IQ correlates well and reliably so with good grades in all classes among students.
@@devinmes1868 Yes and my computer can do calculations more quickly than he could and recall more information than he could. Yet there is still no computer program that can write a half-decent book, write a good song, produce original visual art, or diagnose someone with a disease reliably. I don't know that much about Kim Peek, but it is important to remember that being a savant is not equal to having a high intelligence. In fact it is almost the opposite. People with high intelligence are very adaptive and can do many different tasks and can adjust to different environments. Don't get me wrong, savants are very impressive and certainly have their own place in life. But I don't disagree with the assessment that they often aren't as intelligent. That is not what IQ tests measure, nor should it be what IQ tests measure. People with high intelligence can be well suited for almost any job (funnily enough one of the most intelligent people ever famously lived out his days as a grocery store clerk). Personally, my perception of people who are intelligent is that they can understand and solve problems incredibly quickly and thoroughly. This is why often a big part of intelligence tests are interesting riddle or mathematical problems. Because they test how quickly someone recognizes the parameters of the problem and how they can solve it. I think its important to remember that intelligence isn't how well your brain functions at a certain task. It's how well your brain can learn to do new tasks. That's why IQ tests are designed so that it's hard to study for them ahead of time. It's about adapting on the fly.
In 2007, doctors found a guy in France that was functioning normally with 90% of his brain eroded away due to fluid buildup. IQ was a bit low at 75, but otherwise normal. His name was withheld in the article.
Just a comment on the epilepsy part of this video; epilepsy isn't necessarily lifelong. I myself had Petit mal epilepsy from the age of 10 to 17 and haven't had a seizure since (now 27).
Yeah, same. I had rolandic epilepsy as a kid, but grew out of it by the time I was ten. Which most kids with that condition do - it’s the most common type of benign childhood epilepsy. And I didn’t need daily meds either. Just had some in case I I had a seizure, which were thankfully very mild
Well, if we go by a pedantic definition, you're never truly "cured" of epilepsy, thus it is a diagnosis that will always be with you in your clinical history. For practical purposes though, it is like you said, sometimes seizures diminish and eventually can stop altogether for an indefinite period of time, which something important to note because most of the patients I've interacted with seem to hold the notion that being epileptic means being sensitive and in danger of any potential "trigger" or "surprise attack" for the rest of your life, when that isn't necessarily true.
There’s myths.. and there’s rumors.. the question about “can’t prevent a stroke” is definitely not a “widely held belief or idea”, which is the definition of a myth.
Yeah. The synapses in the region of the brain relevant to whatever task your performing will light up, and that will account for a small fraction of the total synapses that can be used. This is the basis for a very cool form of brain surgery, wherein neurosurgeons will map your brain activity in real time to see which areas of the brain 'light up' when you do various tasks, so they figure out where your most important neural pathways are, and if they have been disrupted or damaged during surgery.
@@ale-bt3pd dynamically though, it changes every moment as needed I imagine, Using 100% of your brain would mean you are having a giga-seizure/stroke I guess?
Small comment on withdrawal from social interaction using videogames, this is usually a symptom of an underlying psychological issue such as depression, social isolation (e.g. due to bullying) or lack of stimulus for someone with high intelligence. This does give a feedback loop because it causes further lack of development of social skills, but is hardly ever the initial trigger
That's an amazing conversation we have seen the very nice question I want to see is 1:44 and 12:33 just gives a clear concept I wish ✨ THE CONCEPT OF MOST INTELLIGENT (❤ HUMAN BRAIN ❤) MORE CLEAR ✨
90* hours of gaming my good man. Not 19. 19 are rookie numbers lmao. But seriously, 35 hours are ok so long as you don't neglect your other duties, whether school or work
IQ as a standalone is a measure of person's ability to identify and discern patterns - how fast, the complexity of patterns, e.g. from simple "find a missing picture of four" to identifying unmentioned amount of patterns in a set of many. Visual, verbal, sequential, and, most importantly, "existing". The last one is the difference between a functional and devoid-of-reality brain. "Social Intelligence" and "Emotional Intelligence" are pretty flexible and can be learned/improved with repetion and, again pattern recognition. I mean, psychopats apply just that. There is no imitate "abstract" and "logical" thinking. You either see it or not. Asperger, as an exception - it draws a cleaner line between the two.
I think the whole 10% of brain use is a myth thats often mischaracterized under how much of our bodily functions we control. For exampme there is hundreds of thousands of involuntary actions that occur in our body that we cannot actively control but our brain is responsible for. Which makes me think how supernatural someone would be just to be able to control their involuntary actions. For example being able to turn off pain receptors or sensations of heat and cold. While these sensations are neccisary for survival sometimes turning them off can prevent other issues. Like when we get set on fire we often panic, but if we could turn off our sensation of heat and pain we can get into the mindset to quickly duck and roll. Or maybe slow our heartrate when we have been bitten by a venomous creature to keep ourselves alive for longer.
I also believe there is a misunderstanding about the whole 10% issue, it's not about only using 10% of your brain, what is really meant by this is, we only use a fraction of our mental capacity or potential, think about highly intelligent people, that are also very knowledgeable, individuals, that know 7 languages, remember, everyone's name, can do complex math in their head quickly, these people are using the same amount of their brain as everyone else, but they are also using a much higher capacity of their brains potential than others. and so many studies have been done on this, educational stimulus, at a very early age, has a major influence on how much of the brains potential we are taking advantage of, experiences, create new neural pathways, it's all about the "wirings", so under this context, it is very plausible that the average human is only using "10%" of their brains, potential.
Intelligence testing is definitely not perfect. The tests don't always provide an accurate measure of intelligence for eople with disabilities or people with neurodevelopmental disorders, or those with learning disabilities. It can be even more difficult to measure if that person is gifted and disabled or nonverbal. So they are definitely only one instrument of many.
@@psychicspy Statistical reliability relies on normed data. When a child comes in and their testing shows high variability, that screws with the statistics. You take two children with a 120 IQ. One child is neurotypical and all of her subtest scores were within the normed stasticial variability. You can say that yes, the likelihood of this child's FSIQ being an accurate measure of their IQ is pretty high. Now take a twice exceptional child- gifted and disabled. This child also has an IQ of 120, but their subtest scores are extremely varied. Their lowest score was 91, and their highest score was 144. The normed data is for under a 23 point variability- this child has 53 points variability. This happens in less than 1% of time in intelligence testing. How does an average FSIQ of 120 help this child? The truth is, it doesn't help them. It isn't an accurate representation of their intelligence or their weaknesses. These children are often stuck in the middle and can't get help for their special needs or their gifts.
@@sj4iy Ever heard of outliers? Just knowing that a person had a learning disability would be reason enough to exclude them from the set of normal people who have taken an I Q test.
@@psychicspy An outlier is still a person affected by the fact that the test was not made for them. When IQ testing determines whether someone can recieve enrichment or special education at school, that's creating a lot of problems right there.
@@sj4iy No. It's solving a whole lot of future problems by ensuring that those with the most cognative horsepower get the attention they deserve so that one day they can help the rest of the cognatively elite figure out what to do with the slobbering masses that are rapidly out breeding the carrying capacity of this planet. Just one example of the positive contribution they will make.
Social and emotional intelligence are not really conscious ways of problem solving to me but more in the department of intuitive perception. Not really sure why we label it as intelligence and thus branding people lacking some of it as "unintelligent".
Yep. Thank you. The terms were absolutely made up because human beings have a tendency to be incredibly insecure about their intelligence and this gives them more potential outs to preserve their egos. I'm not saying the concepts are made up. But yes, intelligence is a misnomer here and contributes to soooo many of the infuriating and brain-rotting takes of the general public about IQ and intelligence.
"fish makes you smarter" comes from iodine deficiency. Seafood is a good source of iodine. Prior to iodized salt, people who did not eat a seafood based diet had iodine deficiency which causes a lower average IQ of about 15 points.
A person's intelligence is measured by how they exercise the basic rational capacities: he who understands abstract concepts can form true and correct judgments and can reason out clearly.
9:40 As a kid, in the 60s,I was told to eat fish which contains a lot of phosphorus that is good for your brain. Actually many other foods contain relevant quantities of phosphorus like chiken, pork and organ meat (liver, heart). The problem is that phosphorus is not important for brain alone, Phosphorus is needed for the growth, maintenance, and repair of all tissues and cells, and for the production of the genetic building blocks, DNA and RNA. Phosphorus is also needed to help balance and use other vitamins and minerals, including vitamin D, iodine, magnesium, and zinc.
"You are born with all the brain cells you're ever going to have, and it's up to you to take care of them."--That is an incredibly powerful statement that we should wake up to every morning.
humans go through different intelligence quotients throughout life. so saying that a chimpanzee is as smart as a human (albeit a child) is a factual statement. maybe you should think for 5 seconds before expressing those thoughts
You can get the benefits of fish without the drawbacks (needless killing, mercury, microplastics, PCB's, biodiversity loss, contributing to the environmental damage caused by the fishing industry) by eating plant based foods with ALA Omega-3 like ground flax, chia, and walnuts, as well as by taking a DHA/EPA supplement made from algae.
I think maybe the myth about different sexes having different brains probably comes about because of the difference in hormones and the testosterone. For instance, lots of testosterone in males may cause many things; one being greater risk taking - whether that be success in the business world, or be the choices that made the man sitting inside a prison cell. The brain itself would be the same from an observation standpoint, but so much more would be going on behind the scenes.
It is also because sexual attraction is linked to the size of some part of the brain (using homosexuals as reference)bAnd brain studies on transexuals.
Women being more emotional is a fact. You don't need to be a scientist to put two and two together. Look, women have periods and those periods which last from 3-7 days per month right And don't periods affect mood and emotions ? Next pregnancy, which is around 9 months and also with emotional changes afterwards. Considering that women have from 1 child to like 7 depending on where they live, that's a great contribution isn't. You also add menopause emotional differences to that Doing math women if there are no differences between men and women when they are not affected by pregnancy and periods the fact that well they are affected like from 10-40% of the time of their life by this factors. That alone makes them more emotional. How the hell do you say things like understand we get emotional when is that time of the month or when we're pregnant but can't you add two and two together because of it?
I want to note that the last part of the video where Satoshi mentioned that you are born with "all the brain cells that you are going to have" migth be a bit misleading. A concept that was very common up until recent years is that you are born with all your neurons and once a neuron dies it DIES and it doesn't regenerate. However, by now there have been studies that show "neurogenesis" is a real thing, even on old brains c:

Lol the size is because men's heads are bigger. There are certainly women that have larger brains than some men. The proportions are so similar that no part has a difference that is statistically significant.
I do believe some people are born intelligent and I do believe that some people develop intelligence through being naturally curious. I have proven this with me vs a few people in my family. I've even notice that people who lack a certain level of intelligence have child like tendencies. My sister, father, and a few of my cousins. Let's go back to being naturally curious and how it develops intelligence. I have notice that a person who displays a high level of curiosity as a child tend be good at a lot of things and they can use other subjects to explain things that they are not an expert in very well and get most of it right. Many people don't realize that their is a difference between being smart and intelligent. Smart has a lot to do with decision making while Intelligence deals with decision making, problem solving, and creativity. Not just because you are intelligent doesn't mean you are good at all three equally, but you still posses the quality to get all three done regardless. A person who get all A's is considered smart which goes back to decision making and memorizing. Society reveres them, but a person who is a mechanic is considered not as smart, but people do not realize that this person is intelligence because putting a machine together requires all three that I mentioned before. This is why I say books doesn't make you successful, but hands on experience makes you successful. The subconscious mind is quicker to absorb when you do.
Just a huge cope It lacks any substantial evidence and reasoning I used to make these kind of argument in middle school with my friends..we all thought we developed some huge reasoning capability with intelligence while sounding like this Thankfully realised and out of that phase
Thank you for this video. All of those myths have been taught to me during high school. And the high school teachers were so sure that their curriculum and lessons were factual because they were taught the same from the previous generation.
11:36 The notion that behavioral differences between different sexes is purely based on nurture is fallacious. There are a multitude of morphological differences between the brains of biological females and biological males at birth. This has been shown to be true in humans, as well as other mammals. Even biologically male and female chimpanzees show clear behavioral differences at a very young age. I wanted to link to some studies, but youtube often removes my comment if I post links.
Name one. Tried to find one in Langman, but no. Brain development is tied to patterns. If you have a boy and u raise him to be in touch with his emotions, to cry when sad, to explain that girls will hurt him when they get angry etc, his brain will adapt and u will see a typical female brain development.
To age better : New ongoing longterm studies in france show that ("altruistic, compassion type") mindfull meditation (comfortable) makes a huge difference for aging better (wile), better than for instance starting to learn a new language or vs. changing nothing. Actual change in the brain begins actually also to become detectable after 2-3 years 'practice' (that, BTW, becomes à pleasant need).
A clarification for the privacy myth: A Therapist service is sometimes use to screen people within an organization whereby the Therapist works for the interest of the organization not the subject/patient. This means that the privacy of the subject/patient is secondary to the interest of the organization. That is who pays the therapist defines the loyalty and privacy interest of the therapist.
Same goes for prodigies, thank you for the left and right handed people even now there's people still say left handed people are evil. I beg to differ my little brother is left handed and so is my sister in law his wife I know lucky. Isn't hereditary could play a part in a stroke my dad had a few of them mostly light one's.
There is some evidence that left-handers have higher rates of psychotic disorders like schizophrenia. Also, strokes run in my family, but my family were also sedentary, overweight, diabetic, and had very poor nutrition. My cousin had a major hemorrhage at 30 years old, but he only ate microwave pizza, didn't exercise, and lived an extremely stressful life. A lot of health issues are not genetic, but we often inherit bad lifestyle which is something in our control. Exercise, fish oil, magnesium, are all very good at improving the vasculature and reducing risk of stroke
@@EhurtAfy Agreed. And yikes, sorry to hear all that. Reminds me partially of my family and me :( But in our case, the bad lifestyle etc. is caused by ADHD/us being untreated for years.

Well, if size doesn't matter, then all the books about evolution of the hominids into H.

We have many tests to measure many things. They’re not all perfect but just because they’re not perfect does not mean they’re useless. IQ tests don’t have to be perfect but they are useful and they do test a wide range of mental abilities.
I’m wondering if all strokes can be prevented though.. I work in neuro-oncology and our patients with brain tumors are at an elevated risk for stroke. Im not sure if this is due to their medications or because of tumors themselves. I can’t speak to their cardiovascular health, but sometimes they will get strokes and are otherwise healthy people who aren’t overweight and don’t have a history of cardiovascular ailments. Hailey Bieber apparently had a stroke recently. I guess all of these people had unhealthy hearts? Idk. Really curious about this.
You can prevent strokes due to preventable causes (of course), but there’s always gonna be those freak incidents where a perfectly healthy person has one
As a PhD neuroscientist, I can tell you that Neurologists (MDs) aren't the best people to debunk myths about the brain. Here are some things this video gets wrong: 1) Chimpanzees are not as smart as humans 2) 100% of your brain is working (i.e. is on) all the time. Not all of it is contributing to your consciousness, but it is doing something. You will never be at 70% brain on or anything like that unless you're in medical crisis (e.g. stroke) 3) Yes, memory does decline with age. The plasticity of the brain and the ability to form new memories are particularly subject to decline 4) Yes, there are (TONS) of sex differences between male and female brains. The idea that male and female brains are identical is nonsense and ignores decades of science
Just a genuine question I’ve always been curious about- are the differences between the sexes brains due to socialization, or is there some sort of inherent structural difference? How much of it is nurture vs nature essentially.
I've never understood how the myth that brain size indicates intelligence took hold when birds exist. Have you ever seen a crow or a parrot? Tiny brains, genius birds. I mean come on, they can _talk._
Chimps are not as smart as people. What is missing in this conversation is encephalization quotient, which is an attempt to analyze the relationship between brain mass and body size. It's not a completely linear ratio, and individuals will vary. For example, it can account for differences between men and women because men have larger bodies than women, their average brain sizes differ in a way predicted by encephalization quotients to have an equal average intelligence. It's not precise in predicting a person's intelligence, but better at estimating an average intelligence for a species.
Wait a minute, there are plenty of studies showing differences in brain connections between the sexes. Don't gender horomones affect brain development? I have my doubts about this point. Can you provide some literature?
The interesting fact is that most of old myths from 1600s or 1800s seem to be very popular, the reason why it is very easy to believe in that (you may overconfidently think that you don't have any false believe but the fact is that we always have some incorrect knowledge) is these two reasons: Reason 1: because it is INTUITIVE. Way before modern life and technology, the only way to figure out MOST of knowledge is through intuition, you think it MAY work, and if it SEEMS to work, you just believe in that Reason 2: because it is RARE to happen. What does that mean? Let take a look at heart attack, seems to be 2 to 3 times you witness it in your life, the younger you are, the rarer to experience it, or car accidents, most of the time when you are a witness is that you are a person on that car already and when car accident occurs, you are the person who need to be rescued and not the reverse, or sleep depride, it's so rare to see a person who works 8 hours a day for 5 days a week will find at least several months do nothing and sleep well, do exercise, and relax to experience the insane healthier life style, it's so rare and for those who have the chance to do so, they are already debunk the myths. In general, for myth believers, there are no way to verify if it is a myth or not because the chance you witness it is rare and the chance you are the only one who do it is even rarer, most of the time you will call ambulance, or someone who fortunately a doctor near there to save the patient. Therefore, most of myths remain debunk purely because it's hard to debunk it in daily life, the only way to know and debunk myth is through learning, watching educational videos, and we never have enough time to know every knowledge in the world, so there are always some myths remain inside us that we never even notice that they are myths in the first place.

IQ is kinda like horsepower. Even if you have high horsepower, if you have poor grip, down force, high weight, poor aerodynamic, your car is still gonna be slow as hell😂
IQ is not fixed though, continuous education can increase a person's IQ
It's silly to want to believe that a kid after pre-school taking an IQ test would score the same if they take it after college.
Especially looking at the IQ tests which use specific formula that you can sorta train to discover, but also, you can generally train your brain to take tests better by taking tests over and over again.
Pretty sh## argument. iQ is not horsepower. You dont go around killing people like a car running over people. If you have High IQ just because u lack grip, down force etc etc. Usually IQ stands to denote how fast you understand certain things if not most things, a HIGH IQ individual is less prone to anxiety, erratic behavior and understand what most people don't around him if 100 people have 100 IQ and 1 individual comes with 120, he will certainly have higher Odds of becoming their leader if these 100 men have 120 IQ then a men with an IQ of 140 would be able to stand out. Its always ALWAYS gonna be a factor of genetic mutation as well as environment factors. People who strive to do something else and unique entirely will have higher probability to have high or better IQ then rest of the people/most of the people.
@FredCarpenter-vv9ld Assuming they have the correct answers, you can definitely train yourself to get better scores with similar styled questions.
The problem with IQ tests online is that if a person takes it, they have no idea if they got a question right or wrong. So there is no way to review the answers to their questions. Hence, you can keep making the same mistakes over and over again.
So, if you taught your cousin some of the solutions to questions you know they have no idea on how to solve, I'm thinking they might get higher results the next time they take the quiz.

I’ve been an RN for almost 30yrs & the stuff I learn about brains has changed so much since I was new. We’ve learned SO much but still some things we just shrug & say “i don’t know. Brains are weird.”
Also, does being ambidextrous change how one’s brain reacts? (As opposed to be left or right-handed?) just curious.
As an ambi', myself, I'm gonna have to say there's going to be a lot of "It depends" for that question...
I was born "left handed" and ended up LEARNING ambidexterity to get through life easier. My mother (God bless her) was a staunch supporter of the idea of "Never tell that boy he can't do something that way." SO the teachers at school got backed off when I picked up the right handed scissors (or the left handed ones) or any other utensils simply because they were in better shape and more available than the ones for my "handedness"...
Part of the "trouble" with ambi' is that I lose some of the sense of "right and left" orientation, because there's less influence on the cues for it. I had to just memorize it, where the "normal" person bases it on which hand they write with... AND the other direction is just the opposite... BUT I didn't get so much of that. Sometimes I write with one hand, but when it gets tired or I just don't feel it, I'm working with the other one... haha...
The "advantage", however, is that I'm not so limited. Having learned to do things with both hands, relatively equally well, while it's taken me just a little longer to develop that "hand-eye coordination", now that I've got it, I'm generally more intimately involved in any skills with my hands... Being able to carry on a task when one hand gets tired, simply changing the duties assigned to the hands, DOES give me more "range" or "endurance" for it, and that adds to productivity... AND if I injure a hand, well, the other has less trouble taking up the slack, so to speak. I'm just a little bit less inconvenienced... and you might be surprised at how aggravating life can get when the hand you USUALLY wipe your butt with doesn't work well enough to do the job. (lolz)
Someone who was just naturally ambidextrous might have developed their "hand-eye coordination" faster than me and not suffered nearly the disadvantages of putting up with dull scissors or trying to negotiate Caligraphy with the screwed-up "bent" pens... Switch-hitters in baseball tend to be prized by teams, making that bar of performance just a little lower than maybe the rest of the players, whether orthodox or "south paw".
AND A LOT of it's going to depend on the culture they were raised in, and their parents and general "support" for it. Some cultures still stigmatize left-handedness as "of the devil" so there can be dubious mistrust and outright abusive tendencies for such a little detail. That can stunt the skills with the left hand, and diminish their appreciation of a talent... just as much as quietly practicing on its own can be a great benefit, building the neural pathways and creating more dynamic flexibility in a person's dexterity overall.
IN ANY CASE, I hope this helps a little bit. I'm no pro' about neurology, of course... JUST a perspective that might offer even some subjective information about how life is experienced, and the evidence (as I have anyways) that suggests there most certainly IS some difference in brain development between right handed or left handed folks and ambidextrous folks.
I DO still have a dominant eye (my right one)... BUT just about everyone has one side of their binary systems (the organs and nerve nets in pairs) that's got a little shorter pathway to the brain and a little faster impulse travel, a little more dominantly reliable than the other... That's probably normal even for the most ambidextrous among us. ;o)

From what I’ve read, most parts of the brains do not make new brain cells, but neurogenesis does occur in the hippocampus and glial cells are possibly able to thicken or regrow as well.
Just wondered about that since I often heard that it’s a myth that we only have a finite number of brain cells after we become adults.
They stated that myth at the very end of the video.
Was wondering about the same thing
Neurogenesis in adulthood has been observed in 2 regions of the brain ( the Dentate Gyrus in the Hippocampus and the Sub Ventricular Zone of the lateral ventricles) in mice. In humans, it has been proven only in the Dentate Gyrus and the investigations regarding Neurogenesis in the lateral ventricles are still ongoing.
Therefore, we don't have a finite number of neurons. However, Neurogenesis in the above mentioned regions does slow down as we grow older.

When I was 13 I was diagnosed with Asperger's. This was in '08, before they redid the ASD to the 3 levels they are now. I scored a 145 on the IQ test I was given at that time. It was not until 12 years later when I was 25 that I found out I have Aphantasia. MOST people with Aphantasia have no idea they have it. I just thought that when people were saying to "imagine" they were only using a method like an analogy or metaphor, not that they LITERALY meant to picture something. I think this makes the test I took very flawed. I can remember there being a good portion involving mental assembly of shapes into a final form. I don't think Aphantasia has influenced my logical or academic intelligence, but my social instead. I have a really hard time relating to people. Empathy and sympathy are not in my head a bit. It's hard for me to relate my own experiences with others, since my recall is mostly like reading a script. Things just exist as a list of details in my brain, but obviously not a visual. I have inner voice. Some info I just know and don't try to recall, it just happens. I am also completely ambidextrous. I will grab a writing utensil and use it with whatever hand is closer to it, without thinking about it, and make the same poor quality penmanship.
Most people with epilepsy can be treated with medication, but there are some instances where medication is not a viable option and people are able to manage seizures better through dietary changes/regulation and/or surgical intervention.

IQ presupposes that the best way to measure intelligence is by testing an individuals pattern recognition aptitude because it is the closest synthetic analog for learning problem solving skills. That makes IQ scores an excellent predictor for aptitude in STEM fields and technical employment. However it is not an effective predictor of aptitude for creative or interpersonal skills, which are equally as important for personal success in life.
In the field of it, IQ is certainly a predictor of success.
One thing I've always wondered is, since our eyes are at the front of our heads - as it is in most species with eyes - why is the sight processing part of our brain located at the back? You'd think it would be at the front closer to the eyes. Also, how did the whole left side controls right side of body and vice versa come about? That seems like a very strange layout too.
I also thought about this strange positioning of visual cortex when they mentioned it in the video.
The answer lies probably in how the parts of brain evolved over the course of primate origin.
Optic nerve as it traverses the brain has projections into the temporal and parietal lobe which also processes the optic signal and final image is formed in the occipital cortex.
About the contra lateral control, it's because many nerves crosses to the other side either in the brain stem or the spinal cord.
It's most likely because of something called somatic twist that occurred in vertebrates during the course of evolution. Invertebrates don't show this anatomy.
I think because of the complexity and the success of life on Earth, people gain the idea that all life is optimised and designed almost perfectly but there are a lot of flaws and pointless waste of resources. A few examples of these unintelligent designs: giraffe’s laryngeal nerve is much longer than it needs to be, human hips and birthing canal are narrow causing birthing to be dangerous and painful and tasmanian devils’ have 4 nipples yet have a litter as large as 30 resulting in very few surviving. These are just a few examples but every species has at least a few flaws in their design.
My point was that there isn’t a good reason for it, its something that didn’t create a big enough disadvantage during our development as a species to evolve

the videogame thing is so true. There's obviously trash in all entertainment and videogames are no exception, some really do feel like they're slowly strangling each of my neurons, but I've found that games like Snowrunner really make you think logically and do a lot of risk vs reward calculation, throwing in variables like your vehicle's capability or potential obstacles on the road. Same as sim or sim-adjacent racing videogames, you have to be aware of your own capability as a driver, your car's capability, your tyre wear, changing weather if it's a feature, strategy, other drivers...Videogames really do give you hand on experience to form connections regarding quick decision making, strategy and risk vs reward thinking that a book, a school lesson or a documentary can't teach you, specially for younger kids that can't get into IRL situations that build those connections.
“Chimps are just as intelligent as humans”…
I can't see how that could be the case without some kind of definition of "intelligence" that would have to be designed for it to be true, somehow, and yet it's hard to imagine what it could be to be minimally valid. The best I could come up with is that perhaps by some neural correlates of intelligence, chimps' neurons are just as good, or some intelligence-related tasks. Chimps were actually found to have a significantly better working-memory than humans, and that's key for human intelligence (or highly correlated to IQ), but that's obviously not enough for human-like intelligence.
This is one of the best episode of these expert debunk videos. 😊
Yes. Please bring these guys back.
Pretty rich that neurologists are speaking about psychology topics as if they are experts. I understand that to the layman it may seem as though they should know a lot about psychology, and therefore IQ, but these are really two very different fields. Neurology is all about the physiology of the brain. While physiology can certainly affect cognition, neurologists aren't the ones measuring that. If a neurologist's patient is having cognitive issues, they may image the brain and run various tests to look for abnormalities, but how do they measure any potential cognitive deficits? That's right. They refer them to a psychologist to take an IQ test. This really turned me off from this channel as a whole. It's a real problem when experts pretend to be an authority on things they're not because the general public will just eat it up without question. I probably learned more about IQ in my one semester of cognitive science in undergrad than these guys did throughout their entire academic career. It just isn't a focal point of neurology.
Also, brain size does matter. It's just not the most important factor by a long shot, but it does likely matter. It's just that other things that make up the structure of the brain are believed to contribute much more to our intelligence such as cortical thickness. Brain size has a positive correlation (though admittedly weak) of 0.3-0.4 out of a possible 1 to intellectual capability. Having a larger brain than Steve doesn't mean you are smarter than Steve, but if your brain is significantly larger or smaller then it might be a good indicator of something. You just can't compare size when making interspecies comparisons due to the aforementioned structural features of the brain that we now believe contribute the most to our intelligence.
What's even more hilarious about this video is her example of the bear. Bears have significantly smaller brains than humans. It's not just the size of the animal that determines the size of the brain like she tries to claim. Many large animals have very tiny brains proportional to their body mass and this data is easily found in a google search. Embarrassing! Humans have one of the highest brain to body mass proportions. I seriously doubt it's mere coincidence that the animals in which we've observed the most intelligence behaviors also seem to share this high ratio of brain to body mass (dolphins, whales, elephants).
I would hate to have this lady as my neurologist. Did she even pay attention in class? What is even going on here?

We need such videos debunking popular myths regarding health 👍🏻
IQ tests measure a number of different mechanisms for your intelligence, and even the primary determination of how fast someone can spot and process patterns is very valuable data, not to mention IQ is highly correlated with many outcomes in life. Just because we found some more nuances to define doesn’t mean we need to throw it out completely.
IQ is pretty stupid honestly. There is no such thing as being “smart” in order to be the definition of smart that everyone thinks would be to literally be at least intermediate in almost every subject math, science, history you name it. It doesn’t matter if you went to high school or whatever. You can still be dumber than a rock and I know this because I have met people who went to good schools and can’t even tell you how to toast bread. Sure IQ tests test pattern recognition but not common sense and really general knowledge. To live in this world you need to have common sense the basics of math history and science and you need some creativity as well. Someone can score good on an IQ test but they couldn’t tell you how grammar works or what the mitochondria is.
It is the most robust and reliable psychometric measure that psychology has ever produced, but yet many researchers are not a fan of it.
I think a lot of that dislike stems from the implications of IQ as a very stable and robust measure of intelligence. Research (and this is actually some of the small fraction of social science research that is reproducible) shows that you can keep a high IQ child down with bad education, bad nutrition, bad parenting, etc, but you can't make a low IQ child high IQ via optimal condition, speaking to a reality where individuals have more of an IQ potential that differs from others. That is a very uncomfortable position to be in for a psychologist or someone working with social science, because the deterministic nature of it means that some people are simply destined to not achieve certain things in life.
You two should look up Kim Peek. That man was capable of accurately recalling the entire contents of over 12,000 books. He was capable of quickly calculating the day of the week that you were born just based on the date you gave him. He's widely known as the "Rain Man," the man with an incredible brain.
His IQ was 87. I think that should speak for itself.
@@devinmes1868 IQ is a predictor of success, it's not a predictor of how fast you calculate or remember books.
The strength of IQ lies in that it correlates reliably well with income, product sales, academic papers published, albums sold, bestseller books published, etc. And also that it speaks to a general intelligence, rather than multiple intelligences. For example, high IQ correlates well and reliably so with good grades in all classes among students.
@@devinmes1868 Yes and my computer can do calculations more quickly than he could and recall more information than he could. Yet there is still no computer program that can write a half-decent book, write a good song, produce original visual art, or diagnose someone with a disease reliably.
I don't know that much about Kim Peek, but it is important to remember that being a savant is not equal to having a high intelligence. In fact it is almost the opposite. People with high intelligence are very adaptive and can do many different tasks and can adjust to different environments. Don't get me wrong, savants are very impressive and certainly have their own place in life. But I don't disagree with the assessment that they often aren't as intelligent. That is not what IQ tests measure, nor should it be what IQ tests measure.
People with high intelligence can be well suited for almost any job (funnily enough one of the most intelligent people ever famously lived out his days as a grocery store clerk). Personally, my perception of people who are intelligent is that they can understand and solve problems incredibly quickly and thoroughly. This is why often a big part of intelligence tests are interesting riddle or mathematical problems. Because they test how quickly someone recognizes the parameters of the problem and how they can solve it. I think its important to remember that intelligence isn't how well your brain functions at a certain task. It's how well your brain can learn to do new tasks. That's why IQ tests are designed so that it's hard to study for them ahead of time. It's about adapting on the fly.
Always informative to have real experts (10 + years of actual study and work) talking about their subject.

Just a comment on the epilepsy part of this video; epilepsy isn't necessarily lifelong. I myself had Petit mal epilepsy from the age of 10 to 17 and haven't had a seizure since (now 27).
That’s awesome.

I had rolandic epilepsy as a kid, but grew out of it by the time I was ten. Which most kids with that condition do - it’s the most common type of benign childhood epilepsy. And I didn’t need daily meds either. Just had some in case I I had a seizure, which were thankfully very mild
Well, if we go by a pedantic definition, you're never truly "cured" of epilepsy, thus it is a diagnosis that will always be with you in your clinical history.
For practical purposes though, it is like you said, sometimes seizures diminish and eventually can stop altogether for an indefinite period of time, which something important to note because most of the patients I've interacted with seem to hold the notion that being epileptic means being sensitive and in danger of any potential "trigger" or "surprise attack" for the rest of your life, when that isn't necessarily true.
Great video, but is "you can't prevent a stroke" really an existing myth that's out there that people believe??
Yes.
There’s myths.. and there’s rumors.. the question about “can’t prevent a stroke” is definitely not a “widely held belief or idea”, which is the definition of a myth.
I mean you can not reduce the risk to 0%, but you can reduce it.
Also, "you can't prevent a stroke" is a somewhat different postulation than "you can't reduce the risk of stroke", which is the one they addressed.

We use "only 10% of our brain" at a time the same way that we use "only 33% of our traffic lights" at a time.
Yeah. The synapses in the region of the brain relevant to whatever task your performing will light up, and that will account for a small fraction of the total synapses that can be used. This is the basis for a very cool form of brain surgery, wherein neurosurgeons will map your brain activity in real time to see which areas of the brain 'light up' when you do various tasks, so they figure out where your most important neural pathways are, and if they have been disrupted or damaged during surgery.

IQ as a standalone is a measure of person's ability to identify and discern patterns - how fast, the complexity of patterns, e.g. from simple "find a missing picture of four" to identifying unmentioned amount of patterns in a set of many. Visual, verbal, sequential, and, most importantly, "existing". The last one is the difference between a functional and devoid-of-reality brain. "Social Intelligence" and "Emotional Intelligence" are pretty flexible and can be learned/improved with repetion and, again pattern recognition. I mean, psychopats apply just that. There is no imitate "abstract" and "logical" thinking. You either see it or not. Asperger, as an exception - it draws a cleaner line between the two.

I think the whole 10% of brain use is a myth thats often mischaracterized under how much of our bodily functions we control.
For exampme there is hundreds of thousands of involuntary actions that occur in our body that we cannot actively control but our brain is responsible for. Which makes me think how supernatural someone would be just to be able to control their involuntary actions.
For example being able to turn off pain receptors or sensations of heat and cold. While these sensations are neccisary for survival sometimes turning them off can prevent other issues. Like when we get set on fire we often panic, but if we could turn off our sensation of heat and pain we can get into the mindset to quickly duck and roll.
Or maybe slow our heartrate when we have been bitten by a venomous creature to keep ourselves alive for longer.
I also believe there is a misunderstanding about the whole 10% issue, it's not about only using 10% of your brain, what is really meant by this is, we only use a fraction of our mental capacity or potential, think about highly intelligent people, that are also very knowledgeable, individuals, that know 7 languages, remember, everyone's name, can do complex math in their head quickly, these people are using the same amount of their brain as everyone else, but they are also using a much higher capacity of their brains potential than others.
and so many studies have been done on this, educational stimulus, at a very early age, has a major influence on how much of the brains potential we are taking advantage of, experiences, create new neural pathways, it's all about the "wirings", so under this context, it is very plausible that the average human is only using "10%" of their brains, potential.

Intelligence testing is definitely not perfect. The tests don't always provide an accurate measure of intelligence for eople with disabilities or people with neurodevelopmental disorders, or those with learning disabilities. It can be even more difficult to measure if that person is gifted and disabled or nonverbal. So they are definitely only one instrument of many.
Psychometricians generally regard IQ tests as having high statistical reliability.
@@psychicspy Statistical reliability relies on normed data. When a child comes in and their testing shows high variability, that screws with the statistics.
You take two children with a 120 IQ. One child is neurotypical and all of her subtest scores were within the normed stasticial variability. You can say that yes, the likelihood of this child's FSIQ being an accurate measure of their IQ is pretty high.
Now take a twice exceptional child- gifted and disabled. This child also has an IQ of 120, but their subtest scores are extremely varied. Their lowest score was 91, and their highest score was 144. The normed data is for under a 23 point variability- this child has 53 points variability. This happens in less than 1% of time in intelligence testing. How does an average FSIQ of 120 help this child? The truth is, it doesn't help them. It isn't an accurate representation of their intelligence or their weaknesses. These children are often stuck in the middle and can't get help for their special needs or their gifts.

Finally debunking the 10% myth
What about IQ consistently correlated statistically with success in careers? What's the explanation for this?
IQ is an outcome
LMAO no, success in careers is far more correlated with your family connections.
I think maybe the myth about different sexes having different brains probably comes about because of the difference in hormones and the testosterone. For instance, lots of testosterone in males may cause many things; one being greater risk taking - whether that be success in the business world, or be the choices that made the man sitting inside a prison cell.
The brain itself would be the same from an observation standpoint, but so much more would be going on behind the scenes.
It's mostly social expectations and role socialisation. Men are not expected to be social. Women are not expected to be great problem solvers.
It is also because sexual attraction is linked to the size of some part of the brain (using homosexuals as reference)bAnd brain studies on transexuals.
Women being more emotional is a fact. You don't need to be a scientist to put two and two together. Look, women have periods and those periods which last from 3-7 days per month right
And don't periods affect mood and emotions ? Next pregnancy, which is around 9 months and also with emotional changes afterwards. Considering that women have from 1 child to like 7 depending on where they live, that's a great contribution isn't. You also add menopause emotional differences to that
Doing math women if there are no differences between men and women when they are not affected by pregnancy and periods the fact that well they are affected like from 10-40% of the time of their life by this factors. That alone makes them more emotional.
How the hell do you say things like understand we get emotional when is that time of the month or when we're pregnant but can't you add two and two together because of it?

However, by now there have been studies that show "neurogenesis" is a real thing, even on old brains c:
I noticed that you didn’t rip up the Memory slide, lol! Thanks for this presentation - seeing these 2 smart, empathetic professionals gives me hope for the future of our youth.
Um... At the end of the video it was stated that "you're born with all the brain cells that you'll ever have".
Didn't research show that adult brain does grow new neurons?
I'm a bit confused here...
Not to rmention I think the brain grows in the first year after birth, and then end up at a static size.
@@Carewolf Diameter and content are two different things...
You can have the same container but still swap it's brain cells content a bit.
@@trillionman2105 To assemble an entire puzzle you need lots of pieces but if you have most of the pieces already in place adding one or two extra pieces means the difference between having the whole picture or some crapy pile of junk.
Is quantity really the important part here?
male brains are 10% overall bigger in size. female brain is bigger in prefrontal cortex, while male has bigger occipital regions. I am surprised they didnt know that
They don't know much, 80% of what they claimed in the video is patently false.
@@yeetdeets yes, and I just pointed to a few most obvious facts. Where they found such ‘experts’?
@@yeetdeets dunning Kruger
Lol the size is because men's heads are bigger. There are certainly women that have larger brains than some men. The proportions are so similar that no part has a difference that is statistically significant.
I do believe some people are born intelligent and I do believe that some people develop intelligence through being naturally curious. I have proven this with me vs a few people in my family. I've even notice that people who lack a certain level of intelligence have child like tendencies. My sister, father, and a few of my cousins. Let's go back to being naturally curious and how it develops intelligence. I have notice that a person who displays a high level of curiosity as a child tend be good at a lot of things and they can use other subjects to explain things that they are not an expert in very well and get most of it right. Many people don't realize that their is a difference between being smart and intelligent. Smart has a lot to do with decision making while Intelligence deals with decision making, problem solving, and creativity. Not just because you are intelligent doesn't mean you are good at all three equally, but you still posses the quality to get all three done regardless. A person who get all A's is considered smart which goes back to decision making and memorizing. Society reveres them, but a person who is a mechanic is considered not as smart, but people do not realize that this person is intelligence because putting a machine together requires all three that I mentioned before. This is why I say books doesn't make you successful, but hands on experience makes you successful. The subconscious mind is quicker to absorb when you do.
Incredibly subjective post and ultimately meaningless because of it.
Just a huge cope
It lacks any substantial evidence and reasoning
I used to make these kind of argument in middle school with my friends..we all thought we developed some huge reasoning capability with intelligence while sounding like this
Thankfully realised and out of that phase
I think I'm in love with Dr. Billakota.
Thank you for this video. All of those myths have been taught to me during high school. And the high school teachers were so sure that their curriculum and lessons were factual because they were taught the same from the previous generation.
Development is key with consistency...
11:36 The notion that behavioral differences between different sexes is purely based on nurture is fallacious. There are a multitude of morphological differences between the brains of biological females and biological males at birth. This has been shown to be true in humans, as well as other mammals. Even biologically male and female chimpanzees show clear behavioral differences at a very young age.
I wanted to link to some studies, but youtube often removes my comment if I post links.
Yeah, I think that one was woke protection.
No links, just lie
Name one. Tried to find one in Langman, but no. Brain development is tied to patterns. If you have a boy and u raise him to be in touch with his emotions, to cry when sad, to explain that girls will hurt him when they get angry etc, his brain will adapt and u will see a typical female brain development.
@@ionescusarah5398This is not true at all. Evolution has taken care of it
Also mention pattern perception. Some of it happens before the neural signals even get to the brain. Interesting. Very interesting video. Thank you.
To age better : New ongoing longterm studies in france show that ("altruistic, compassion type") mindfull meditation (comfortable) makes a huge difference for aging better (wile), better than for instance starting to learn a new language or vs. changing nothing.
Actual change in the brain begins actually also to become detectable after 2-3 years 'practice' (that, BTW, becomes à pleasant need).
A clarification for the privacy myth: A Therapist service is sometimes use to screen people within an organization whereby the Therapist works for the interest of the organization not the subject/patient. This means that the privacy of the subject/patient is secondary to the interest of the organization. That is who pays the therapist defines the loyalty and privacy interest of the therapist.
Oh God did I enjoy you torn apart the paper about IQ!!! Thanks to educate people on the limits of IQ tests!
Same goes for prodigies, thank you for the left and right handed people even now there's people still say left handed people are evil. I beg to differ my little brother is left handed and so is my sister in law his wife I know lucky. Isn't hereditary could play a part in a stroke my dad had a few of them mostly light one's.
There is some evidence that left-handers have higher rates of psychotic disorders like schizophrenia. Also, strokes run in my family, but my family were also sedentary, overweight, diabetic, and had very poor nutrition. My cousin had a major hemorrhage at 30 years old, but he only ate microwave pizza, didn't exercise, and lived an extremely stressful life. A lot of health issues are not genetic, but we often inherit bad lifestyle which is something in our control. Exercise, fish oil, magnesium, are all very good at improving the vasculature and reducing risk of stroke
@@EhurtAfy Agreed. And yikes, sorry to hear all that. Reminds me partially of my family and me :( But in our case, the bad lifestyle etc. is caused by ADHD/us being untreated for years.
I am left handed 😂
My writing is neat
I draw well (i usually complete all the homework of my cousins in painting)
i score 95% in my exams
And i can never hurt any living creature .....i can't bear that pressure on my brain of hurting someone
And people are shocked by this ....like they do not expect me to behave like a normal human 😂
Brain talking about itself
When someone said you're stupid I'd highly recommend this video show them
"size doesn't matter....
.
.

When it comes to brain." Had me there mate.
I loved this. Hopefully, we'll get a part 2, part 3, part 4...
Well, if size doesn't matter, then all the books about evolution of the hominids into H. Sapiens have to be rewritten, since the brain capacity of the skull was one of the main characteristics of the development of rational intelligence, tools and culture. I would love to see a confrontation between neuroscientists and anthropologists regarding this matter.
Could it simply mean brain mass relative to body size?
@@mindovermindfuck Hard question: crows or parrots don't have a bigger brain mass than other birds and are much more intelligent than most mammals. So the brain/body mass ratio is not always accurate.
@@jupersan Bird also have a very different brain structure so that could explain it.
But as a whole that "myth" was badly explain.
They said the proportion though.
Didn’t some of the early humans types have bigger brains
Did a neurologist just say that chimpanzees are just as smart as humans?
Well they are as smart as human children maybe that’s what they meant but they said it vaguely
Yeah, this was strange
yes? humans go through different intelligence quotients throughout life. so saying that a chimpanzee is as smart as a human (albeit a child) is a factual statement
We have many tests to measure many things. They’re not all perfect but just because they’re not perfect does not mean they’re useless. IQ tests don’t have to be perfect but they are useful and they do test a wide range of mental abilities.
Fascinating... Science is awlays changing... For instance... Some of these debunks will be dubunked soon and so on!!!
Great video!
🧠
I’m wondering if all strokes can be prevented though.. I work in neuro-oncology and our patients with brain tumors are at an elevated risk for stroke. Im not sure if this is due to their medications or because of tumors themselves. I can’t speak to their cardiovascular health, but sometimes they will get strokes and are otherwise healthy people who aren’t overweight and don’t have a history of cardiovascular ailments. Hailey Bieber apparently had a stroke recently. I guess all of these people had unhealthy hearts? Idk. Really curious about this.
You can prevent strokes due to preventable causes (of course), but there’s always gonna be those freak incidents where a perfectly healthy person has one
Please make a video about radiology myths ♡
As a PhD neuroscientist, I can tell you that Neurologists (MDs) aren't the best people to debunk myths about the brain. Here are some things this video gets wrong:
1) Chimpanzees are not as smart as humans
2) 100% of your brain is working (i.e. is on) all the time. Not all of it is contributing to your consciousness, but it is doing something. You will never be at 70% brain on or anything like that unless you're in medical crisis (e.g. stroke)
3) Yes, memory does decline with age. The plasticity of the brain and the ability to form new memories are particularly subject to decline
4) Yes, there are (TONS) of sex differences between male and female brains. The idea that male and female brains are identical is nonsense and ignores decades of science
Just a genuine question I’ve always been curious about- are the differences between the sexes brains due to socialization, or is there some sort of inherent structural difference? How much of it is nurture vs nature essentially.
"Education is not the learning of facts but the training of the mind to think."
I've never understood how the myth that brain size indicates intelligence took hold when birds exist. Have you ever seen a crow or a parrot? Tiny brains, genius birds. I mean come on, they can _talk._
the fact that she said chimpanzees are "probably as smart as we are" at 1:05 made me lose all respect
What makes you think they are not?
Chimps are not as smart as people. What is missing in this conversation is encephalization quotient, which is an attempt to analyze the relationship between brain mass and body size.
It's not a completely linear ratio, and individuals will vary. For example, it can account for differences between men and women because men have larger bodies than women, their average brain sizes differ in a way predicted by encephalization quotients to have an equal average intelligence. It's not precise in predicting a person's intelligence, but better at estimating an average intelligence for a species.
Wait a minute, there are plenty of studies showing differences in brain connections between the sexes. Don't gender horomones affect brain development? I have my doubts about this point. Can you provide some literature?
She's from one of the most woke institutions in the US. What did you expect?
Something does affect brain development, but it hasnt be proven that sex hormones do this. Could be nature, could be nurture
@@ionescusarah5398 Perhaps, but it would be unusual if other settings led to the same outcomes.
I really enjoyed both of you. So sophisticated and direct.
@@priapulida please elaborate!
The interesting fact is that most of old myths from 1600s or 1800s seem to be very popular, the reason why it is very easy to believe in that (you may overconfidently think that you don't have any false believe but the fact is that we always have some incorrect knowledge) is these two reasons:
Reason 1: because it is INTUITIVE. Way before modern life and technology, the only way to figure out MOST of knowledge is through intuition, you think it MAY work, and if it SEEMS to work, you just believe in that
Reason 2: because it is RARE to happen. What does that mean? Let take a look at heart attack, seems to be 2 to 3 times you witness it in your life, the younger you are, the rarer to experience it, or car accidents, most of the time when you are a witness is that you are a person on that car already and when car accident occurs, you are the person who need to be rescued and not the reverse, or sleep depride, it's so rare to see a person who works 8 hours a day for 5 days a week will find at least several months do nothing and sleep well, do exercise, and relax to experience the insane healthier life style, it's so rare and for those who have the chance to do so, they are already debunk the myths. In general, for myth believers, there are no way to verify if it is a myth or not because the chance you witness it is rare and the chance you are the only one who do it is even rarer, most of the time you will call ambulance, or someone who fortunately a doctor near there to save the patient. Therefore, most of myths remain debunk purely because it's hard to debunk it in daily life, the only way to know and debunk myth is through learning, watching educational videos, and we never have enough time to know every knowledge in the world, so there are always some myths remain inside us that we never even notice that they are myths in the first place.
