- Explore the history of IQ tests; how they measure a person’s intelligence and the ways they have been used to justify scientifically baseless ideologies.
--
In 1905, psychologists Alfred Binet and Théodore Simon designed a test for children who were struggling in school in France. Designed to determine which children required individualized attention, their method formed the basis of the modern IQ test. So how do IQ tests work, and are they a true reflection of intelligence? Stefan C. Dombrowski explores how the tests have been used throughout history.

“Our potential is one thing. What we do with it is quite another.”
― Angela Duckworth
Goodness of this thought varies as if u are talking about potential that is predetermined or something other
The first thing to do is to find its gradient
But the IQ test isn't about measuring one's potential.
@@vasudevraghav2109 Potential is unknown. So no one can tell you what you can be, what you can achieve. It's up to you what you will be.
@@djayjp yeah that's true. Even Alfred binet believed IQ is not fixed or ones potential isny predetermined.
I wish school was more like this. If i was taught things with this much passion, detail and importance then I would’ve always paid attention
Agreed 🙌
Agreed
More like teachers and not schools themselves. I used to love physics until high school. Before i had a teacher that would explain things almost like telling a story and with a bunch of curiosity facts; that made want search more about the subject and consequently study more. When high school arrived, the teacher was so boring that I lost complete interest; probably the only reason I still had good grades was because of solid physics foundations from the previous teacher.
Teachers are people. That’s the sad truth. They don’t love what they do, and they don’t get paid much to do it. Especially effecting is this: there is no competition. There isn’t a surplus of teachers competing for the best, but in fact not enough
I agree yet at the same time I have a very charismatic college math professor and I'm still not understanding jack. But that's probably another issue haha.
I’ve got a low IQ, I’m going to uni in September to study nursing, I was told I would never be able to do my GCSEs, I did them and passed. I’ve been tested loads for “issues” and disabilities, I can however excel at non-verbal reasoning though. 😊
Aww good luck with your journey, don’t let these people discriminate you ❤️
Congrats, this proves that you don't need to get a freaking 140 on a MENSA IQ test in order to succeed in life the way YOU want to succeed.
Work hard, and stop worrying about your IQ. It doesn't matter if you have an average IQ, or a genius level IQ. You can still do whatever you want with your life.
Congrats again!
Honestly, good for you! I hope your future prospects go well :)
@@lunariedawn to some degree, it does, but it isn't the greatest way to mesure overall. no one really knows what is since intelligence is relative
@@mo_7199 I'm not talking about intelligence though, I'm just saying that (especially from my own experience), IQ doesn't measure someone's intelligence, but their ability to see patterns and solve problems
In no way does that make one with a higher IQ smarter than one with a lower IQ

That poor soul with 3 IQ...
What about the guy with 3 IQ 😂
He got 3 points for getting his name right.
LoL
He has the mental capacity of plastic.
@@johnsalchichon777 nope. Probably spoke some other language other than English and only knew very basic English.
5:41 "Individuals can't be categorized by a single numerical score" please someone say that to the school system!
Literally no one from the school system thinks that people are categorized only by IQ. Grades in school are a very useful tool, not only to determine a student's conscienciousness, but also to find who has difficulties learning. BUT WAIT, that is not to say that it is the sole factor for the value of an individual, as there are many other aspects that make someone unique. You are simply misrepresenting the school system, which I don't find to be noble.
@@henrilemoine3953 I think that everyone is born in a different way therefore not everyone has the same type of intelligence. For exemple a brilliant writer that has a very good creative type of intelligence might be bad at math because despite his creative genius he has a lack of logical type of intelligence which is the type of intelligence that (for some reason) is privileged at school. This system doesn't measure emotional intelligence either, for exemple as long as a person with low emotional intelligence (like for exemple a bully) is good at solving problems this person will be rewarded by the school system anyway. This can be easily explain by the fact that "creativity" and "kindness" can't be objectively graded, so the system put a number on the only thing that it can put a number on which is "problem solving". This is an extremely unfair system that I definitely did not misrepresented in my comment.
@@stevesoprano8113 very true........ But they don't put a number on ' Problem Solving' they put it on ability to gain marks by screaming every detail they can......
See in real life when u want to calculate u can just look it up in books or computers thats why we have them......
But no no no no!!!!! Lets see their hard drives working.......
Or to china
@@henrilemoine3953 I also disagree with this. Grades do not measure learning deficiencies as you like to believe. And if you watched this video, you will find that trying to grade learning deficiency has no scientific backing and is difficult to measure with consistent results. Tests have to be rigorously designed by industry professionals to produce whorthwhile results and I guarantee no shool makes their staff do this every year for every curriculum. At most they'll do it for the standardized tests, but I refer you to T.E.D ED's video on that subject to learn why that is also ineffective in its current state and why it should change.
When I was 7 my school forced my mom to take me to an IQ test because they wanted to prove I have a learning disability. I scored 139. They decided on their on I have some sort of mental disability and I had regular meetings with the school psychologist where I just draw and played with a hamster, until my mom figure out what they are doing.
I didn't have any disability, I was just really bored in class so I didn't do any homework or participate that much, and I was a very sensitive kid so when the teachers got mad at me I used to hide under my table and cry.
This treatment caused me a lot of problems later on and some of them still effect me to this day, mostly mentally.
The school system is messed up. They think that if a kid doesn't learn like everyone else, it's because he they have a problem. I learned faster then most of my class, so I was bored of doing things I already knew over and over. Now I find it hard to finish assignments and learn properly because I never had to, and now that I need to I have no learning skills.
If instead of taking me out of class to play with hamsters they let me learn faster, I would most likely do better at uni now.
If I was bored I just drew cartoon characters.Most of my teachers were cool with me so they let me get away with it.After awhile of being bored they let me skip 9th and 12th grade. I just realized how lucky I was thanks to you.
I don't think the school system is the only problem,
From what you wrote i think your parents are also the problem,
@@blackpepper2610 My parents were not the problem. I don't know what I wrote that made you think that, but they are fighting hard for me every day, and they always had. Of course they are not perfect, my twin sister and I were their first daughters and I admit they made some mistakes (which they didn't repeat with my little sister btw), but they are both great parents.
Its challenging to raise twins as your first kids. I think I didn't mention my twin sister in my original comment because I didn't think it mattered, but she went through a similar thing.
Right now my parents and my sisters are my only family, and I couldn't wish for a better one. I'm sure you didn't mean to offend me by your comment but it's very important to me that you'll understand it wasn't their fault. They always supported me and I've seen them yelling at teachers and embarrassing themselves to make sure nothing like what happened at elementary school will repeat itself.

Yeah I had to do an "IQ test" for part of my depression diagnosis; it actually tracks visual problem solving, audio comprehension, short & long term memory, and comprehension. The point is to look for underlying factors that may contribute to my depression and past. As it happens, instead of having average values across the board, I have wildly high scores in some places, and average scores in others. As a consequence I take and process in more sensory data than most people, but my memory is slightly uneven, resulting in a learning deficit. It also explains why I tend to think out loud and notice a lot of random details. Sometimes I enjoy taking off my glasses just to give my brain (and eyes because eye strain sucks) a rest.
That's really interesting
Wow
ok
Oh cool! I know depression can affect memory and cognitive function. I have depression too and when it's really bad my grades at school plummet. I can't focus, I feel like I'm in a fog, and it's harder to remember things. I do worse at work as well.

Their actual secret sauce is to tell you things that you wanted to hear whether there’s truth to their claim or not. People like to “learn” things that they already believe.
and uses whatever studies they can find to prove their point without a hypothesis
This reminds me of the Gifted program my elementary school had, in which some kids who scored high enough on IQ tests got to leave the classroom and do fun stuff like make books and have parties. Many parents and teachers hate this program. All the students can enjoy and benefit from fun learning activities, not just the ones who score highly on IQ tests. Besides, it's damaging. The kids in the Gifted program often get inflated egos while other children feel as though they are not "gifted," all because of a flawed test that neglects to measure many other important qualities.
@Martha Speaks It's alright. You were just a puppy.
I feel so much more luckier now...
I've been in a gifted program during school and I don't think what you're saying is fair at all. While yeah, some of the kids there were assholes and the program gave them an unnecessary ego boost, this really wasn't the common trend. Most of us were just nerds who were bored at school and wanted to do something else for a change. These tests weren't useless, they did an excellent job at sorting out the exact kids fitting for the program - fast learners who enjoy learning and aren't reliant on school. You're neglecting to mention the reason these programs exists in the first place - to help people connect. It was an opportunity to finally meet and interact with people similar to me, in an environment where I wouldn't get bullied just for asking the teacher questions or for having good grades. As a result most of my friends at the time were from that program, and it was extremely important for my mental health. Yeah, obviously having fun learning activities is always a good idea for anyone, but cancelling these programs won't help with that. It's just going to give intelligent kids even more of a socially miserable time at school.
I never liked the "gifted" program for the very reasons you mentioned. My best friend was in that program. They went on monthly field trips, played games and participated in a lot of fun activities. They were able to leave class early to do this. Their curriculum challenged their intelligence, further allowing them to grow. This doesn't happen with "average" children. Theyre not challenged or praised for the gifts they have. They're not recognized. It's wrong. So many people are geniuses in disguise.
My best friend always considers me being as gifted as she...however, I was never in a gifted program.( I did land in an advanced reading classes only to get shoved into remedial math classes, lol) I can reason, deduct and predict like no else I know. I.Q tests only test a certain type of intelligence; there are many types of intelligences. The IQ test doesn't take this into consideration. Consequently, a lot of gifted children are left behind because some test said they didn't deserve to be challenged.
@@Niccole-oq8wo I fully agree that the average student should be pushed forwards and challenged more, but how is cancelling the gifted programs going to help with that? Stopping someone from achieving their potential isn't going to help anyone else achieve theirs. All you're doing here is addressing jealousy. If you closed down these programs the budget they use up would just go back into the regular boring school system and everyone would lose. If you think others should have similar opportunities, then open up new programs built for different types of intelligence - don't close the current ones.
Again, you're forgetting to consider the reason these programs exist in the first place - they aren't there because of some nonsensical superiority complex, they're there because people with high IQ tend to be challenged less by school, want to learn more and seek connections with others similar to them. You can argue that this doesn't correctly measure intelligence all you want, but the social environment there is vastly different from what would have happened if they opened it up for everyone.
I was in an awful social situation in school at the time. That was the only place where I actually got to meet similar kids without worrying about bullying all of the time, and I know that I'm not the only one who had that experience. That's a really important thing to consider, especially when talking about younger ages. It sucks that not everyone gets to have an experience like that, but it doesn't mean nobody should.
Every time I watched Ted-Ed I can feel that my IQ increase.

IQ cannot describe u....... It is not even fixed, it varies at different times of a day and depend on many unaccountable factors
@Ashutosh Dubey we don't even know whole brains functioning of various part, let alone full body and we start to measure it with unfaithfull tests....... ' I'm only human after all don't put ur blame on me' ......
The problem is the amount of variation. Sure, if you're hungry, tired, depressed or anxious, ofcourse it is going to play a role in your final result. Other factors do contribute to a fluctuating intelligence range as well. But that does not mean that it is not accurate. The correct manner to observe and analyze such psychometrics (personality tests like big five count as well), is to keep in mind that although the score can and does shift slightly during the day or various mental and physical states, it never results in a dramatic change in IQ score nor does it correspond to a lack of general intelligence.
Unfortunately, we know that while IQ is in part decided environmentally, it is mostly genetically influenced; meaning that it is determined at birth.
Can you manipulate it through environmental means such as nourishment and/or education? Definitely.
Does that mean there is not a fixed cap? No.
So, I would say that each person has a vareity of potentials, abilities and talents, most of which are settled the moment that one is borned. Intelligence (or general intelligence if you'd like) is one of those potentials, and the whole concept of potential is that there is a fixed cap; you can work on yourself and possibly reach your best version, but after that, you hit a conceptual "roof".

Where do you get your information from, Vasudev?
I am studying Psychology and therefore confront myself with IQ and tests on a regular basis, and in fact there are many IQ tests with a very high reliability.
That we do not fully understand all components of the brain yet, does not have anything to do with how IQ tests work.
So please, enlighten me where you get your insight from, that IQ tests have low reliability and do not work.

I am glad that the video makes the point that even though IQ testing has been used incorrectly in history, it isn't something that is useless. We may never have a perfect iq test, but we can use it (and other tests) to learn how to benchmark the human mind. Just as we have with physical tests. However, there will always be exceptions.
I just learned what I would’ve learned in online school for a whole week compressed into 6 minutes.
Your school is spending a whole week on the history of IQ testing?
@@thebatonmaster 40 students. One teacher. 6 minutes?
Wisest 1 I truly respect your opinion. You think that. Everyone thinks differently and you thinking Ted Ed isn’t the best is 100 percent fine. On the other hand, I think that Ted Ed is teaching me all that I need to know for now. Maybe in the future it won’t be the best teaching resource. It seems that you need something a bit more on the deeper meaning side. I agree with you though, the IQ test is great and Ted Ed didn’t cover that in the video. They didn’t necessarily cover everything about the history of IQ in this video, but I think it covered enough for us to know the basics of the history. If you want anything else to be covered just let me know. Also Ted Ed explains it in a more fun and colourful way. That may help students pay attention more and learn more from Ted Ed than what they’re learning in school.
Thank you very much for your opinion. This helped me and it will help Ted Ed get better in the future
@Wisest 1 but the title of this video stated "the dark history of IQ" so expect this will be in a negative standpoint of view... but they still managed the video to be light at the conclusion of this course... you should have been more understanding, not the other way around...

@@kevinhodge4730 They don't, though? If you look at a test's biases, like getting a higher score if you go to school, it explains why it is kinda effective. Someone who didn't go to school would probably be less successful than someone who went to school. That doesn't mean the test scores potential accurately. IQ tests generally touch up on creativity, and other intelligence types.
It is correlated, but because of other factors. It isn't even correlated that strongly.
@@asrnyigit4040 Lookup _spurious relationship_ . Another explanation is that those who are smart happen to attend more school and also happen to score higher on IQ tests. Also, IQ tests only measure one "type" of intelligence- general intelligence. IQ tests do not attempt to capture such loosely-defined concepts as "creativity."

I was given my first IQ test in 7th grade in my 2nd year of public school back in 1974. It was administered to select me for the "academically talented" group the following year where they had us skip some years subjects and combine others- enabling us to graduate high school a year earlier. However no one noticed, in all my years of schooling, that I was severely dyslexic. I was diagnosed at age 50 after I commented to my Dr. that I still couldn't spell my brother Brian's name correctly.

Entered a private school in 1970 at the age of 11, and took the Binet test.

Environment can indeed have a positive effect on one's intellect.
But to dismiss any inherent biological differences on the basis that other things have an effect is dangerous nonsense.
There are a lot of different types of IQ tests out there. Some on them I score very high on, some not so high. I have a phd in astrophysics and was always one of the top students in every class without really studying, so I know what I got upstairs. That said, if you ask me to flip shapes and match patterns for an hour, I'm not going to score that high.
I don’t know my own IQ and honestly I don’t mind keeping it that way. The number does not represent how capable i am to achieve the goals i set for myself
Yes it does. It's actually a big factor on how fast and easier your gonna get your goals. Although it truly dependant on how much motivation you have to reach your goals
I have a sort of low IQ score. I never went to college. But I taught my self animation and now run my own business. Doing well on IQ tests just means you are good at IQ tests. It has almost nothing to do with your creative capacity.
It actually does have allot to do with your self taught learning and adaptation. Knowing you learned animation on your own and were score to run a business alone, I'm guessing you have a write high IQ
Good for you, you worked hard and you became successful. IQ tests though are probably the best at testing the creativity of a person that isn't either self report or those "think of a use or all of the possibilities" tests. Though there are people who score high in IQ tests who aren't creative at all. It's just that creative people are intelligent. The notion that you're just good at an IQ test and nothing else is false and ignores the century of literature that's been comparing the academic/career success to many tested populations. Is this evidence not enough? Or right, it's also found that IQ correlates to other aspects of cognitive abilities which you might consider as pieces of "intelligence." It's a definitional matter if you want to go down that path, but it's been found that higher IQ people have higher processing speeds (There's a .25 correlation between IQ and reaction time), score generally higher on all aspects of intelligence (ex. spatial reasoning, working memory, logic, verbal intelligence. People with higher IQs are also more capable of keeping more factors inside their minds, which if you think about it makes a huge difference in the real world or on IQ tests.

IQ does not measure your success, only your intelligence. Best advice is not to look at your results or if better, don't do an IQ Test at all.

@@ArnieOcfemia There is actually a very strong correlation between childhood IQ and success later in life.

Made me feel like a genius for a while but I’m pretty sure it was fake
Juzer Morudwala If an iq test is online, it’s usually fake. But don’t worry about it too much, as people across the intelligence bell curve can all be very successful
IQ tests, if you make good use of it, can help identify natural abilities, interests as well as weakness. They could help save years of struggle and can tell what should one do to be at their best.
The first thing to know about IQ is that you can increase your score by at least 20 points through training.
The second is that IQ scores increases in countries that improve their school system. (mentioned in the video, along with other factors that improve learning like affordable and available health care)
It works well as a "general knowledge" screening, but that is about it.
I suspect you could use IQ tests to compare different groups in a country and see if there is systematic biases against certain groups, given that we would expect any random grouping not based on academic results to be unbiased. (Things like skin tone or gender comes to mind.)

Well, thats like a A- or sthng. Not to brag but, the best score i ever got was 91 :)

me and many friends who are neurodiverse and have learning disabilities were refused support in high school because we scored high on an iq test, i ended up dropping out of school because of it. the systems in place have an incredible detrimental affect on students yet they are still the standard
Then why dont you get help for it. If you dont go out of your way to compensate for any inability, thats your fault. I got ADHD, and atleast put effort to get counselling and medication. How tf were you refused support too. Is your school that underfunded it cant afford another paycheck for an EA?
As with all things humans do, we adapt and get used to thinking in a specific way. If you continuously do conventional IQ tests, you will see your score rise steadily as your brain starts to adapt to using that specific skill/trait. If a loved one interrupts you during your test, you will most likely find it hard to empathize with whatever problem they might have, because you are tuned in to solving a problem - not simulating another persons life in your imagination.
Our brains are incredibly adaptable and plastic, and it frustrates me that we have a tendency of rashfully concluding logically, when most problems are much more ambiguous than at first glance. Overall we have a tendency of thinking ourselves better than others and trusting ourselves and our beliefs more than anyone else's.
IMO the smartest people are the ones who realize their own ignorance
"I know that i know nothing" - Socrates
I agree with everything you said. One thing to note is that you might as well not practice IQ tests because the people who score the highest will learn how to inflate the score the fastest.
Another interesting and beautifully animated/directed lesson! Thanks, Ted-Ed!
As a psychology major, I can say that this topic is explained quite perfectly
*Army Alpha*
*Army Beta*
If my intelligence is fixed, and inherited and there is nothing i can do to improve or change it, what reason do I have to do anything? Why should I bother trying to improve myself at all.?
Why is your intelligence fixed? People born with disorders may struggle to do the same things that people born without them will do. This is not the case for every situation, and disregarding the disabled as useless is a mistake. They can provide fresh perspectives a lot of the time. And though you may struggle there is no hard cap on what anyone can achieve. Then again, there's value even when not achieving.
@@Kryptnyt You are missing the point. I never said intelligence is fixed, or that disabled people are useless, I don't believe that at all. My point is that the belief that intelligence is something that is inherited and can't be improved through training and effort is a incredibly toxic belief. and there are people who actually believe this. It absolves people of personal responsibility, if I can't improve my intelligence, why should I make any attempt to improve myself? Also, for people who are very intelligent and succesful, They didn't work for their success, they simply inherited it. You see the problem with this toxic idea?
The IQ test actually makes the assumption that you will steadily grow more intelligent as you age, if the calculation presented in this video is true. So I'm confused where you are being told that you can't improve from. But yes, closed-mindedness is bad.
You guys rock! Please keep posting more! Your videos are informative and amazing to watch. I learn something new and exciting with each video and I believe it helps me to increase my capacity to think in ways I couldn't have done alone. Thank you :D
The best iq test is how many ted ed riddles you get right
Hmm, then. have a very low IQ...
Love the artwork in this video.... there is a nice Hergé feel to the characters.
As far as I know it wasn’t a IQ test that was used for the selection of army in US, it was a personality test which is something totally different. The Flyn effect is based on the lack of new norms. A large group of people must be tested to determine the norm. It is highly possible that IQ of 100 is no longer the average and that the distribution has grown larger.
Fun fact: there's a correlation between the average IQ of a country and how well off its population is in terms of technological advancements
Possibly but so far there has been no IQ testing on that scale.
I mean yeah, obviously a more logically advanced population would be inclined to be more technologically advanced.
fun fact, most people who think they are smarter for being born in a country with good conditions, will likely not contribute to any technological advances themselves.
@@andreasrasmussen6362 it's usually the minority of the workers who contribute to technology advancements, the engineers, scientists, programmers, etc
Simple, colonialism. Countries didn't develop in a vacuum.
What do you mean? i AM the dark history of IQ test.
You haven't seen nothing yet 🤣💀💀💀
Alexandra Baker,
So using an IQ test to justify racism, forced sterilization and murder are not dark?
One thing I’ve noticed about intelligence is that usually children who like school more end up learning more from it. Maybe the biases and stuff end up dampering someone’s chances to learn?
It’s not that they like school more, but that they like learning more.
That's true to an extent, and children who are not challenged enough in class could ignore the content. Jeremiah Noar is right, but this topic might be more of a matter of conscientiousness.
School: hey so uhh here's a bunch of math you build a thing around the star with it
Internet: dyson spheres are a structure used to harvest energy from stars, they require a special kind of reflective panels because it's too hard to produce enough solar starships that would be reliable...........() okay now take this stuff, this is diameter formula, this is the use of materials, this is stable orbit formula, this is to calculate the replacement requirement time, this is not important, you can just search it up anytime.
The ability to identify abstract patterns that aren't based on things I've already been taught? Pfffft. When is THAT ever gonna be useful in a complex world???
“Don’t let an iq test determine your success in life”
I.Q. is not the same thing as intelligence, just like how strength is not the same thing as athleticism.
Thanks Ted-Ed you reminded me of my "below average" result :(. Now i know it shouldnt be compared to other people especially, my classmates.
I recently got an assessment on the possibility of having ADHD and I'm pretty positive a reason it was dismissed (not denied, mind you, but my psychologist told me if I did have it, I had it under control) was because I got a high IQ score on the tests, too.
What ? I got diagnosed with adhd and My "high iq" was part of it,cause it showed big differences between different parts of the test for eg Short term memory was bad and under the average but problem solving was way over average etc and having big differences like that is a part of adhd and beibg neurodivergent (so having adhd ,beibg autistic etc) is foten accompanied with higher or lower IQ since it's a difference in the brain (but it's not Always the case)
Aldo to add,: I didn't just do an iq test we also talked i got avsked questions about My chilhodd,different environments,My feelings,like etc and Tool attention tests all to get a precise inderstansing of My brain and I didn't get diagnosed only with adhd
@@alicia1636 Thank you for sharing your story with me!
The reason I commented about it is because she sounded dismissive of my complaints about having a hard time focusing on anything that didn't bring me pleasure, and sometimes even in things that do, because I had good grades in school and because of my concentration while taking the tests. The assessment was largely inconclusive to me, so I didn't get diagnosed and I don't claim to have it. It could very well be something else, after all.
I'm still being medicated though and it has substantially improved my daily life even though I can still get distracted often. But it feels less overwhelming, even on a low dose.
I wasn't claiming I believe intelligence equals neurotypical, either. It actually offended me a bit because I have an autistic friend who also has ADHD and she's brilliant, we're both really passionate about Literature, so I went a bit ??? when she said it. Made me feel like I wasn't being taken seriously.
@@alicia1636 Also, I'd like to apologize if it looks like I implied having a high IQ and being neurodivergent were mutually exclusive, because I know for a fact they're not. Thank you, though, for sharing this with me, I really appreciate it!
Of course its works for them,who designed that tests
So we can reach to the conclusion that IQ tests are useful and partly true for determining problem solving skills, but not enough to categorize people. But my question is, in the future there might be a more precise and correct tests. Isn't that led to a categorization among people again?
@Otto Coldbeer but in the past we can see the examples of that it used in group level. Yeah we use it now on individual level, but if the test will become more trustworthy in future, wouldn't that led to a categorization on people?
@@selimsenturk4889 that categorization might be useful, like helping teacher to know who to help. But at the same time, it may leads to discrimination between people.
@Otto Coldbeer also we have to consider the children that needs special treatment. It can be the children that are having learning problems or it also could be the children that are highly intelligent.
IQ tests are useless, we all know artificial intelligence IQ is low but it beat people with high IQ
@@truthboom Artificil intelliegence IQ is very high, it just can't be measured my human tests.

School Psychologist who gives these tests. 100% truth. I still give them, but also include a variety of different pieces of data and sources to back up a hypothesis for learning disabilities or intellectual disability. These tests are also important to observe children in a structured 1 on 1 setting for other academic and behavioral concerns!

All these people talking about how IQ isn't important...
IQ is your ability to adapt and solve problems. It's how fast you can recognize a fault, think differently and learn new things. For many people IQ won't have be an impact on their life, but for some people it does.
CEOs (or the ones right below them) need to solve different problems each day, they need to recognize patterns and occasionally think differently. That's why CEOs actually tend to have higher IQs.
For many people, like writers, reporters, mechanics, nurses, truck drivers, chefs ets. IQ won't be important. That is not to say they aren't smart. You can be bad and good at everything you do, but these jobs require different abilities.
Therefore, you shoudn't be to hard on yourself because you have an average/below average IQ. It will probably not matter.
And you SHOULD pursue your dreams, because that's what life's about.
All you do is see how well you understand Rick and Morty and scale from there.
Let me guess...
That it's dated and doesn't really represent one's intelligence?
@Otto Coldbeer A quick search says otherwise:
_"IQ tests are misleading because they do not accurately reflect intelligence, according to a study which found that a minimum of three different exams are needed to measure someone's brainpower."_
@Otto Coldbeer Worry not, that's the tendency with studies and such: the fact that they need more information to be up to date via further investigations to prove their true value and accuracy.
@@geoleo965 Do a slower search please, you are wildly misinterpreting the information at hand. There are numerous different IQ tests, ie. CogAT, DAS, DAS-II, OLSAT, Otis-Gamma Test, Stanford Binet, etc...
@@cFlakeOfficial Did you skip the mentioned *guess* and *quick search* part? Please, read properly beforehand; furthermore, the point I mentioned stands: further studies for actual veracity.
You're being needlessly judgmental & redundant.
@@geoleo965 Further studies being actual IQ-tests. IQ-tests do accurately reflect intelligence up to a certain point (around the 140-145 mark). You made a guess in your first comment, the second one made it seem like you were stating a fact.
In the last minute of the video, "oh, BTW, IQ tests are actually good at measuring reasoning skills."
Okay after like 10 minutes of reading this comment section, it's summed up like this: People talking about IQ tests despite not knowing anything about them.
First of all, intelligence is the easiest thing to measure in psychology. The literature has been done, testing has been done over and over. The techniques derived from measuring the psychometric have also been used to accurately determine other aspects of the field of psychology. Done, so if you question the validity of these techniques you question the entirety of psychology.
Questioning the established definition of intelligence (IQ, general cognitive ability, whatever) is going to be a hard take, as other psychometrics of intelligence have already been done and correlated to even further establish the tests' credibility. For example: Take reaction time, which has been found to have a .25 correlation. That means smarter people generally think faster. People with higher IQs can also maintain more digits inside their head at once and manipulate those abstractions (ex. say that string backwards). What does this mean? They somehow figured out how to write the number in their head? No, their brains are more capable of maintaining more factors inside their mind. You can actually try to visualize a cube in your mind and add a certain amount of details to each of the faces, and then try to rotate that abstraction. Your IQ is doing that, and the higher it is the more details you can hold without dropping.
TLDR: Statistics have shown that IQ determines how many things you can keep your head at once, mostly determine how fast you can think, how well you can rotate an object in your mind, how well you do in school (though hardwork can be a factor), your financial success (.5 correlation), how well you can recognize patterns, how fast you learn a video game, blah blah blah. Of course there is going to be a little room for variance in this, but it's literally the most solid of all of the psychometrics.
Btw the higher your IQ, the more likely you're going to be higher in a certain set of cognitive abilities but weaker at another.
It's horrifying how they have used these tests to assess a person's value, which it does not. Even though it has a depressing history, it doesn't invalidate the test itself. There is no connection to actual wisdom about life with intelligence, and being a nicer person has 100% more value than scoring higher on this test.
1:15 15 isn't the only sigma value in use.
1:24 There is fairly broad agreement where the definition of fluid intelligence is concerned. Most would recognise it as *_the capacity to think logically and solve problems in novel situations, i.e. independent of accumulated/acquired knowledge._*
Testability itself is a more contentious subject. While the quality of tests and the manner in which they are administered might at times undermine results, the principal focus should be on the fluid component. I would dispute there being
15 isn't the sigma value, it's 1 standard deviation, sigma is the square of a standard deviation
So this is what started tests in school, yep humans be humans
I have low scores in school test not because I have low IQ, it just that I'm too lazy to study..yes laziness is the main problem
Laziness was always the problem.
you don't study for iq tests

If Hawking was here, he probably would say :” I have no idea. But people who brag about their IQ are losers”

IQ does predict life outcomes well when MULTIPLIED/FACTORED with personality profiles measuring conscientiousness. The underachievers with a high IQ would likely score low on conscientiousness.
I belive IQ is partially inheritance (big chunk of it) like when u play a game its determined ur based stat but u need to gain experience to sharpened ur mental thinking, the older u are the harder IQ to change
But under any circumstance test should be with their native language becouse language isnt part of the test
A thoroughly informative channel with content with a taste for the scientific method
Why is everyone concerned to find out their I.Q. score. If you're doing OK and feeling well then you're fine. Just be yourself. Then mabey after college or sometime find out. That's not all that important in life. What is important is who are you going to marry, how will you work and at what job, and a social life with kids ( or mabey kids destroy as social life). Also yes, schoolwork is very important. You ask what schoolwork involves, well I'll tell ya. Taking notes and doing class work, homework as well then studying for tests. If you do this you'll be passing with flying colors. Not to worry, it's all simple.

“...through selective breeding...”
The what
you dont wanna know, trust me
They mean that in America they sterilised people w “undesirable” traits such as being non white, or having a low IQ
It still doesn't change the fact that someone with IQ lower than 80 can NEVER EVER be more productive than the resource required to train that person for certain tasks.
People with IQ lower than a certain threshold will always be a net burden to the society in terms of measurable productivity.
HOWEVER, it does NOT mean that person is useless at all. People can contribute to society in many different ways.
IQ is also still the BEST predictor for financial success (it is the highest correlation factor), but NOT the ONLY predictor.
Still, it's pretty powerful, considering how wealthy background make being financially successful very easy, but high IQ actually prevail that.
Just think about it - imagine you have choice of inheriting a large portfolio of rental properties with passive income of $8,000 per month but have IQ of 80, or would you rather be born in a middle class family with the IQ of 150? - I would choose the latter every single time.
Do you have any sources for this? I only vaguely recall hearing something similar but with SAT scores instead of IQ tests.

If there were no IQ differences in ethnicities and genders, nobody would be disputing the IQ test.
Imagine writing a test that would decide whether you'd live or die...
You would DIE you would get sterililazed meaning you cant have children
The fact that IQ has been used by deeply flawed ideologies doesn't make IQ deeply flawed. It's still the single most reliable test in all psychometry, and even if we don't like to admit it, it's the best predictor of lifetime material success we have.
“...and better nutrition.” The United States: are you sure?
Yet IQ testing remains the most effective predictor of professional and economic success.
Is it? Based on what studies?
Despite it's dark history IQ is a useful tool. It's very hard and in fact arbitrary to decide what exactly is intelligence, but it matters little because IQ is a very good predictor of multiple important life outcomes. Research has shown that when groups of friends rank each other according to perceived intelligence and compare this to the IQ-scores of the participants, the ranking matches. IQ is one of the strongest predictors of income, criminal behavior, education level, job performance, welfare reception, having an illegitimate child,...
