Why IQ Tests Are Stupid 

I love how people see IQ the same way DragonBall characters see power levels and they don't realize how stupid they look.

When you watch Rick and Morty once

Your IQ basically tells you how good you are at taking IQ-tests. Even the professional ones are flawed because you can train for them. (yes you can train for them.)

Another important point is that group averages tell you nothing about any particular person you might meet. You still have to treat everyone as individuals until you can make an informed judgement.

I purposefully failed every question and it said my iq was 85

Dunning - Kruger effect all over the comments section.

Ha! My IQ is 508! Although, there may or may not be a “negative” in front of that, but that’s beside the point.

Adam said it best: Only thing that IQ tests shows are how good are you in doing IQ tests

_"People who boast about their IQ are lossers."_ *- Stephen William Hawking (1942 - 2018)*

I have a friend who got a 90 on an iq test and I remember thinking that, “yeah, he’s not smart.” Seconds later, I dispelled my gut reaction. He isn’t dumb, just not smart in the way society taught me was right. He’s comedically smart, though his jokes may not be conventionally smart, they’ll still make you laugh. And I think everyone is like that. Everyone is smart in some way. I think you only have the right to say someone is stupid when they’re bad at absolutely everything, which most people are not.

To get smarter you need to: That's right.

Some things that this video did not talk about. IQ tests are supposed to be scaled based on the _age_ of the one taking them, this is how IQ is supposed to stay more or less constant throughout one's life. (for reference, IQ is calculated by taking your Mental age and dividing it by you Physical age and then multiplying that by 100. So if you are 15 but the test shows you were correctly answering questions that people at age 20 tended to answer correctly then you would have an IQ of 133. 100 is the "average" because if your Physical and Mental age are 1 to 1, then the equation would spit out 100). If you are just taking some random test online that claims to measure IQ, then you're not taking a real IQ test and it will not measure accurately. This is much easier to calculate in children to adolescence and even young adulthood because we know a lot about what functions the brain is still learning, and can create IQ tests towards those age groups to see what they have grasped and what the tasks the brain is still developing. So why take an IQ test? Originally and professionally it is used for helping to diagnose medical disorders, more specifically some mental and brain disorders. Obviously, this _could_ help diagnose a disease earlier on, potentially helping to find treatment earlier rather than later. But obviously, IQ tests are *NOT* the only thing that weighs that decision. If you are taking an IQ test outside of a medical environment then you're taking an IQ test for the wrong reason. It is also important to have only taken an IQ test in a medical environment because the doctors prescribing these tests _know_ how to target a test toward an age-group. While there _is_ still debate on the effectiveness of these tests, they have and are used to help diagnose disorders and have helped do so.

It took me a long time to understand why people were so obsessed with IQ because upon looking into this idea at a very young age I couldn't figure it out - I knew how these tests worked, I knew about IQs and EQs and all these tests people took to determine a number for their worth and only after once again investing some time in understanding the method later in my life I finally came to the same conclusion I always come to if something doesn't add up logically - people are incredibly uneducated about many things in live and buy into the most outrages lies all the time, to misunderstand tests like these is childplay with all of the scientific fetishism of these numbers going arround. If I had never done my research, I wouldn't know anything about these tests in particular. I workout to an obsessive degree and was very insecure about myself for quite a while growing uo as many people are so naturally, I was very curious about this kind of "objective measurement" of something so comparable until I started to question it. If these tests feel like logic puzzles, look like logic puzzles and work like logic puzzles - then what makes them so special? I scored well with multiple of them without any kind of training but as I figured that all of these tests had repeating patterns that are incredibly similar to a degree where a basic mathematical education could probably double your score in many of these sections, it started to feel more and more like a compeltley overhyped idea that had long lost its original meaning and I can't help but feel a little bit proud about my 14 year old me because even back than the whole deal seemed off. I hope more people come to the same conclusion I did because as long as people will try to rate themselves like that without actually understanding what they are doing, misconceptions about these kinds of things will unfortunately prevail with a widespread second rate media attention giving a spotlight to what ultimatley ends up being a test that measures your ability to take a test. If you go through any comment section about this topic, you will l realise that they are really a medical tool, not a "job interview measurement".

I can agree... when I was 14 I paid to take a Mensa IQ test that took 3 hours to complete. My IQ score was 155, however I am autistic and have severe social anxiety, and struggle with foreign languages greatly. I am very strong with mathematics and science, and general logic problems, but incredibly incompetent in many areas.

My hot take: The reason IQ scores actually don't matter that much, and the reason why actually intelligent people don't usually preface their contributions to humanity by claiming to be super sMaRt, is because social intelligence is also a part of.. well.. intelligence. A social species is what we are, and we also do reason rationally about our surroundings. Can we all just agree that, at the very least, being a smart, wise and good person has little to to with analytical skills? Now, for all of you big brain people out there, yes having a good acuity is a naturally usefull resource, but purely percieving without understanding is also an empty shell. Read, listen and learn stuff bois and grills

My teachers thought I was retarded (in the medical sense) when I was a kid because I struggled to read and write; I took multiple professional IQ tests and they showed me to be above average, this lead to other tests and it turned out I was severely dyslexic; I was then able to get help to largely overcome this and now I'm doing well. IQ tests aren't innately stupid, they can be very useful and in some cases life changing; I understand the importance of discussing how we use them, but acting like negative uses are inherent with the tests themselves is just dishonest and unhelpful.

my IQ on one website is about 80, on the other 142, thats the point i knew IQ is dumb

Damn. This one went way past IQs and told everyone to just love each other. This is what we need, y’all.

The guy with the world's highest IQ works a bouncer for a night club, in my eyes that proves that IQ isn't everything

I see what you did with that title.

My iq is over 900 because i watched rick and morty

I have never been good at math. My I.Q. is well over 130 in some tests, but if there are math questions the score suffers. I.Q. values are relative to whoever is tested and therefore are difficult to quantify.

The problem I have with IQ assessments is that when discussed, the fact human beings are subjects, not objects, is completely forgotten. The tests don’t take into account factors such as confidence, self-belief, and stress-resistance. They also don’t factor in whether a person takes the assessment seriously, nor whether the person has been informed of the implications should they score high, or low. All of the above can play into how a person performs during an IQ assessment. A hyper-anxious person may go into fight-flight mode under the pressure of being assessed. That would negatively affect their ability to concentrate, alongside short-term working memory. Which could show as below average ‘Digit Span’ and attention skill. Someone who suffers from severe self-doubt may second guess all their answers. They may not complete all the questions and assessments in time. The self-doubt could show up as below average ‘Processing Speed’ by the standards of the IQ measures. In reality, the person’s processing speed may be average or above average. That’s because IQ tests don’t take into account subjective, internal states. They assume cognitive performance is independent of inner emotional state. To any rational person, that idea is completely implausible and beyond incredulous. It’s often cited that IQ correlates very closely with life success. How about this: life success correlates with confidence, self-belief, and stress-resistance. Features of personality that have a profound impact on how someone performs during a timed test, such as an IQ assessment. On a personal level, I have noticed that people who report a high IQ commonly have confident, stress-resistant, and blunt, matter of fact personality profiles.

You are, I think, overlooking the fact that the way IQ tests are now used is far from why theyre were made. They are supposed to be used in a controlled environment, by a higly trained medical professional, who will use the results as only a tool to help initiate the best course of action in helping a patient. This is very far from the falacy that are online IQ test. Plus, medical IQ tests aren't supposed to be an absolute metric of "Hey, I'm the smarter guy !", but only one of many components used to understand a person's psyche.

I am currently majoring psychology; The IQ tests that are applied fail to assert and assess important facets of intelligence (creativity, problem solving, emotional intelligence, multitasking, corporal intelligence, self control...). They only briefily test logic, processing velocity and verbal intelligence, all of which are biased in their own way (the logic tests are LARGELY visual, so, to a blind person, they become impossible). BTW I am reffering to the gold standard tests, such as WISC, WAIS, Columbia... I am obviously doing a rough summarization of the issue, but people must know that these tests serve NO purpose aside from helping form a psychological diagnosis (maybe on learning issues at school). Intelligence is a complex concept that has little consensus among scientints of the field, so it should not be testable until that is reached.

When you get a 70 on an iq test

The only real argument you made in this video was a moral one against categorization of intelligence, then you made a hyperbolic scenario about some kind of dystopian future, when in reality IQ test are still somewhat useful for example they were invented by and are still used by the military to test someones potential you see the military didn't want to waste resources on training people who didn't have the mental capacity to learn certain skills so in that case it can be a useful system however your right in saying the race IQ debate is pointless when dealing with individuals, since the difference inside a group is often greater than the difference between two groups when it comes to humans.

I was hoping for a step by step debunk of IQ tests, their inherent flaws, maybe crude methods of measurement based upon pre-conceived notions and presumption of the participations education and memory as opposed to the utilisation of say, knowledge they have already, logical conclusions and explanations of said conclusions, etc. But I got this video, which I don't think gave me anything new though I appreciate it; so thank you second thought +1 sub for you.

This wasn’t an actual debunking of IQ tests as a concept and instead attacked an extreme position most people don’t even hold.

Somebody didn't get a high iq test

What this video is basically saying is that the way IQ is portrayed is a toxic way to level someone's so called "intelligence". Everyone has different skills. Some people who are good at math's, physics, science may struggle to do art or think creatively in that sense. I struggled to read and write but excelled in art more than anyone in my whole school. IQ is very one dimensional and the ability to solve particular problems are different for everyone.

Please don't tell me that people actually connote IQ with intelligence. THAT's stupidity.

I have watched 3 entire episodes of Jimmy Neutron, thus I posess great amounts of intelligence. over 3 lightyears of IQ, in fact.

Proponents of studying IQ don’t want to put people into jobs based on IQ, it’s about understanding how average IQ shapes societies. In a meritocracy smart people will naturally rise to the top, no one has to force it. That’s why Liberia looks like Liberia and that’s why Japan looks like Japan

This was a great video. Great job! Gonna share this on fb and make it my new “shower thoughts” post of the month.

"Being smart" comes in a variety of forms, such as being smart in agriculture or engineering. Its usually why i dont like iq tests because they don't test your forms of intelligence

As of right now, you have 666k subs...

even though i am an intellectual meritocracist this guy expressed his opposite opinion compared to mine in such a neutral and respectful way that i had to sub.

I was scrolling up in my home tab and saw just the name, I got super excited that GradeA posted for once, then I realized.

I’m not joking when I pressed this video I got a ad for a website to test your IQ XD

fictional character says: i have a 90 IQ and I've studied the Ottoman Empire and normative ethics ethic.I've mastered micro and macro economics I understand the political situation in Syria.

An IQ test is similar to a biography in that it tells more about the author than the subject.

Some facts on IQ tests and why they are not a good measurement of anything: *_It is important that the level of difficulty of the questions is attuned to the results. The average of the participants should always be at an IQ of about 100._* As long as this is not the case, the test is incorrectly "calibrated" and the result distribution is not deemed optimal. The result distribution must then be adjusted with fine-tuning the questions until the average participant reaches a value of 100. *So tests vary from region to region and from participant group to participant group, which makes comparing them nearly impossible.* Have a nice day!

You are so right. I wish more people thought like you

IQ sites are so inaccurate i got 115 on one and 80 on another lmao

3:07 *_but birds can fly._*

How have I've never seen this channel before?

I like your channel a great deal. I think a second thought may be needed on 'whom the country was design for'...from the past actions of the country, it was seemingly design for the few.

Idk why, but everyone seems to be either scoring from 135-145, or 170+. I remember that I took a very bad and exaggerated IQ test. It said I had 143, which I KNOW isn't true. I think that most online IQ tests are very inaccurate and exaggerate your score.

I think you might be misunderstanding the bell curve

Always assumed that IQ tests were not always an estimation of your intelligence but rather an prediction of how fast you’re able to learn and sometimes they can be very manipulative especially when you’re overwhelmed at the moment, that alone can decrease your score but it also depends on other issues in particular instances. When I was a young child they were doing several tests including the general IQ test but in only were momentary measurements and it eventually accumulated to a total of 67. But technically this is understandable since I was born prematurely and had a minor case of cerebral hemorrhage but it wasn’t severe but it did impact the way I process information. Initially I was going to special ed classes in primary school and they also concluded that I wasn’t able to excel academically also confessing that I will need to go to another special ed school once again (middle school) Didn’t agree with this at all, knew I had more abilities than just making small “assignments” and doing the same exercises over and over again and felt like I was misplaced deliberately. Thankfully I managed to go to a regular middle school but I still had to maintain contact with my pediatrician aside of annual visits but everything was going well so far, despite the fact that I needed to learn in a more effective way in comparison with my “normal” classmates but this didn’t affect my grades at all. Right now I’m pursuing another course as sales associate on a higher level and it’s still going promisingly well. Never did another test again but perhaps I didn’t succeed in it since it contained a lot of math and my comprehension in mad is terrible, surprisingly enough I adapt to languages more easily but perhaps I’ll attempt to the IQ test all over again just for my own clarity especially since it indicates that I’m “mentally retarded” but i’m not noticing any of the characteristics. I’m just saying it’s not always necessarily wrong but in some occasions it could be especially if you felt anxious, pressured or overwhelmed. My sincere apologies for my repetitive English in case I made any errors it’s not my first language.

The research done for the bell curve wasn't based on 'racist science'; it was conducted in an unbiased, scientific way (the methodology is publically available). Just because some people don't like the results of a study, that doesn't mean the study isn't accurate or usable.

I remember being a victim of the IQ based scams. Wisdom is considered gold. I never liked IQ test they are often rigged plus I feel like they are just self-esteem boosters.

But I'm pretty sure that IQ tests are supposed to indicate how fast you learn, not how much you know

On IQ tests you know what to think about, and when to think, in the real world you don’t.

Forrest Gump nailed it! "stupid is as stupid does" ....If someone does really stupid things all the time? I simply don't need to see the results of an IQ test ....dumb is dumb. And If someone is over and over again successful in most things? I will consider them quite bright....The proof is in the putting....but who does not just hate when a really dumb person lucks into a position of authority?? Maybe they are someone's relative or else were promoted or hired by someone scared to death of having anyone that might be smarter they are working for them....there are those because I have heard them brag about exactly THAT tactic.

Why need to test your iq if you could just watch rick and morty?

*So you took the cow,bird , and the dog mascot for this reason?*

IQ tests given by psychologists generally aim to give an estimate of cognitive ability based on domains like memory and pattern recognition. I’ve not seen any that advertise they measure things like “emotional intelligence”

This video is old but I just found it so I want to comment anyway. I found out I had dyslexia only at 17, when one of my teachers started questioning why I had such a hard time reading out loud and why my texts were often ridden with spelling mistakes if I was generally a pretty smart kid. So I went through all the testing and whatnot and, wouldn't you know it, I have dyslexia. Before this one teacher took interest in finding out why I seemed to struggle with "simple" tasks while also being clever, I was simply cast aside by teachers, peers and family members as "dumb". After I found out what the problem was and got tips on how to overcome it, my grades went up and I found school a lot more interesting because, for once, I wasn't being treated like an idiot by the people who were supposed to motivate to learn.

Iq dont really matter in the end "Humans have the power to change themselves" Saitama, One punch man

IQ-tests are actually a pretty well researched and operationalized concept within psychological literature testing one's ability to learn, and that's what it's most used for. If I were to teach a person a task, any task, how long would it take for them to learn it? someone with an IQ of 80 does not learn the in's and out's of an engine as fast, if ever, as someone with an IQ of 120. Understanding it does however not decide how well you can perform the task. IQ does not determine your future, it's just part of it. in fact if you go through university with an average IQ, your willpower and commitment of so commendable that if I were looking for a driven candidate, I'd love to pick you. The ability to grasp new concepts differ per individual and usually paired with personality traits as well, testing this is not inhumane or unfair in my opinion. It gives an indication, not a guarantee. We always have to judge someone on the individual level, not based on a singular number. But that number is also part of the individual, why should we leave that out?

IQ mostly measures your abstract reasoning which doesn't encompass the entire intelligence spectrum......it doesn't encompass verbal/linguistic reasoning, musical, artistic, interpersonal/ intrapersonal, kinesthetic reasoning and emotional reasoning. So deducing someone to be dumb if they happen to score lower on IQ tests without taking into account these other factors is an extremely flawed way of judging intelligence.

Iq does not mean anything because imagine the person with the highest iq did not went to school. The person will be considered dumb.

Usually I like your videos, but you seem to be missing the point of IQ tests, and criticize other things which are related to them. IQ tests are meant to measure specific cognitive abilities of people. Not potential(although IQ is correlated with success). And IQ doesn't indicate big differences, so treating people completely differently based on a couple of points is absurd. And all people should get the same basic education(as it is beneficial for them and society). But putting extra resources into people with considerably higher IQ can actually be beneficial for society, and for them(same goes for GPA, doesn't it?). I for example, am in a class of people with an IQ of 135+(tested by a professional institute), and It's very beneficial for us. Additionally I am in a national science program for gifted kids, and regular folks couldn't have been able to survive in this and benefit from it. These programs are very needed for people with high IQ because we waste our time in school. Being able to learn things faster. But because the pacing is fast in these programs, it means that it's not suited for regular people. And in my country, the philosophy is to give people the education that fits them. so extra resources are spent on people with considerably high IQ AND considerably low IQ. EDIT: Decided to unsubscribe. Your channel has 5 minute videos with little actual content in them. I subscribed only for the small minority of actually interesting videos, but as time passed I began to ignore all your videos in the feed, as the quality and topics deteriorated.

The reason those parents got such high IQ scores is because the questions are dumb

POV: You are mad because you scored low on an IQ test.

I read an article that using brain scan imaging is much better at measuring intelligence and even in areas such as emotional intelligence (it does this by measuring gray matter). But however there's one big problem it's not possible to measure with the human eye so there working on a bot for this task. I'd like to see this in the future it would be a much needed development in scientific research.

On any video about IQ, everyone in the comments just happens to have an IQ of 140 lmfao

I feel that I'm scientifically intelligent but emotionally, I have come to agree with myself and accept that I'm a dumbass

It's always the chickens trying to get rid of the test altogether.

Never in the real world are answers to problems laid out in front of us.

actually, by watching all seasons of richard and mortifer 15 times, my IQ has increased approximately a billion trillion times so based on my incredibly superior intellect, i can accurately say that you have the big gay

Intelligence and wisdom are separate things, just saying because you video seem to mix the 2. Intelligence means somebody's ability to solve problems, the more intelligent you are, the more complex problems you are able to solve. Sure, there are multiple areas of intelligence, but IQ is meant to measure an overall intelligence relative to the average Joe and in my opinion it does that well enough if it is done by a trustful source, but, of course, it is never 100% accurate. The point you're missing is that your level on intelligence is NOT written in stone, especially if you are

This video wants to say: IQ tests are stupid. But it actually explains why the people who don't understand IQ tests take them to extreme. In conclusion: IQ tests aren't stupid. The people who take them to extremes are dogmatic (and perhaps stupid)

Thank you for this video

short answer: because all the people in the comment section admitt that they have an IQ well over 135...

I did multiple IQ tests online and had scores varying from 73 to 136 and 189. To illustrate how ridiculous they are. I know full well my IQ is past 200 :p

Thank God, this time there is no kid smarter than Einstein, Hawking and other great individuals.

Well, something needs to compensaste my lack of social skill

I have a form of dyslexia. Because of that, I (Or atleast my Mom, I was like 10yo) wanted to get government support, I live in Germany, we get training paid in cases like dyslexia. The thing was, that you had to test for serious learning disabilitys, to determin if you get the funds. I had to take an official IQ test. I scored a 129. Later in Life I took a Mensa IQ Test and I was a Beta tester for an App designed by PHD students to get a real IQ test onto the smartphone. Both scored above 130. For all who dont know, IQ shows how fast you can learn new concepts, and to some degree it shows if you can learn harder more abstract concepts. You might think Im just here to boast, thats not the case. Im talking about this, because a high IQ didnt help me much in life. I have severe depression. I had to relearn how to learn at Uni, because in school everything was so easy that I didnt have to learn. But in Uni, I have to sit down to learn that stuff, and I never learned how to do that in my School life. I learned the hard way, that you dont need a high IQ, what you need is perseverance, which I just didnt have. I had a friend I always think about if this IQ topic comes up. I didnt know his IQ, but I guess it wasnt very high, he had serious trouble understanding even basic stuff. Irony and Sarcasm went right over his head. But what he needed is time. He took longer to understand stuff, but he had no problem at all to sit down and take that time. He got his Bachelors degree, not by being Inteligent, but just by being able to sit down and learn. I get bored by stuff realy quick (ADD), and did you try to learn something when you get instantly bored? Its just impossible. And my memory is just plain bad. I have friends who can remember everything they learned in school. I can only vaguely remember what I learned 6 Month ago. Like Math, I am realy realy good at learning Math, but after 6 month I wont be able to do what I learned and I have to relearn it. I will remember that I learned it once, but I just cant use it anymore. So a high IQ is not important if you dont do anything with that, and it doesnt mean that you are supperior to anyone. Also what I learned is, to never talk about your oh so high IQ (which is ironic because I wrote all this). I got asked a few times in school if I know my IQ. Everytime I told them, the people who asked started to make fun of me. Even good friends, who didnt ask with any ill intend. What most people dont know about IQ tests is, that your age plays a role. If you have a high IQ as a kid, this can change over time, and when you reach adulthood, you might have a normal IQ. Early IQ doesnt mean much if you dont train to maintain that IQ.

IQ is more of a meme lately than anything else tbh

Someone in my class says he has an IQ of 159 but doesn’t know what AI means.

Thanks this is what I always tell my classmates

Im just here for the smooth ad transitions

To me, IQ tests are simply a way to measure some form of intelligence. Just like a strong person might want to know how strong they are, a smart person might want to know how smart they are. And there are many different tests, so if you score high on one you might score lower on another. But a high IQ would still indicate that a person is smarter than average, in the ways the test evaluates the person at least. Just like you could consider someone who can bench press over a hundred kilograms, strong. Someone who scores high on an IQ test can be considered, smart. But let's say the strong guy always skips leg day. Is he weak because his legs are not as strong as his arms? Or is he a strong guy with weak legs? Or do you consider him strong, solely on their bench press results? Just as strong is a vague term, smart is also vague. And there are different kinds of smarts and strengths, which would mean that a strong person can still be bested by an objectively weaker person in some physical challenges and the same goes for smart people with mental challenges. A person with higher IQ is not always correct in their reasoning compared to a person of lower IQ. It's simply more likely, statistically speaking. Imo. You would probably bet on the big guy in a fight, if you have nothing else to go on, just as you would bet on the guy with higher IQ in a chess game or something similar. I guess IQ tests get a bad rep because many people who consider themselves, smart, might not score as high as they would like. Smart people are probably more prone to be arrogant when it comes to questioning their intelligence. I know I am guilty of this to an extent. People have managed to convince me that my intelligence is way above average throughout my life though, as many unrelated people have come to the same conclusion, just by working with me and listening to how a think about things. But I view myself as a sort of glass cannon, being really smart at some things, and probably even dumber than average at others. But I'm definitely smart enough to know when someone knows more than me about something, and listen to what they have to say about that particular subject. That's probably how I got to the point where I am today. But I have not done a real IQ test. Unless you consider online ones, accurate, which I don't. Just my two cents on the matter.

I have a feeling this is just a very roundabout way of telling us you didn't score very well on your IQ test.

a properly designed meritocracy would judge people based on there work performance not from tests.

Basically, this video advocates for the dismissal of a valuable psychometric tool because... ignorant people misuse it to serve their own aims. Never have I disagreed so strongly with any of your videos. If discriminating on the basis of IQ measurement is wrong (and yes it is), then outlaw the discriminating, not the IQ measure.

I don’t need an IQ test to tell me that I am an idiot. I’m smart enough to figure that out all by myself.

Ok but you can't just sneak in that less intelligent people would be homeless in a mostly automated society. That isn't necessarily what would happen. especially if the things we need are automated.

As someone that administers IQ tests for a living, people care way too much about IQ and put too much stock in how it will determine their life.

My I.Q. is as high as you can get, a perfect 100

Outstanding!

The problem of taking IQ tests serious for purposes other than measuring learning deficiencies in children, is that we move to some weird society model run by technocrats; they might be smart but morally and/or ethically flawed.

someone should have sent this to my family before they got my IQ tested while getting my adhd diagnosis in elementary school, put me in a gifted program, and adjusted all their expectations of me accordingly with an unrealistically optimism

There is strong statistical correlation between IQ and wealth and also crime. That cannot be denied no matter how hard you try.

Hello Second Thought. Your video - as they invariably are - was entertaining and intriguing. I agree with your video's contentions that the very concept of numerically reducing a humans intellectual and cognitive capabilities is a problematic one. Likewise, there are many scientific professionals such as Stephen Jay Gould (paleontologist), Peter Schönemann (Psychologist), or Robert Sternberg (Psychologist) who have impugned I.Q. tests. Furthermore, as was stated in your video, the results from these test might lead to social stratification based on intelligence, alike Aldous Huxley's Brave New World. To conclude, I do hope that humanity can resist use dubious procedures like I.Q. tests to hierarchize itself. Let's not let I.Q. tests become the next Phrenology; a doctrine tenuously based on science that was used to vindicate racial and political views of the time.

Literally my high school Eleanor roosevelt high school had classes only for gifted students who applied to enter at their middle school and for example, In the hallway of classes when all the students were standing in lines the "gifted students" on one side of the hallway and the regular attenders on the other side. You could see that the gifted students were all of caucasian descent(one or two asians) and the regular attenders were all of hispanic and african american descent. The gifted students recieved the best classes and the regular attenders were stuck with the mediocre , and very limited educational topics.
