Agreed 👍
Dear Sugar. Welcome to your destination. Your time has finally come. Here are some happy pills, best to take 2 one hour before sleep and another 2 pills one hour before you wake up.

11:30 the most important part of the whole IQ thing. It's not about "remembering answers" and showing up on IQ test as a big memory bot like some naive people think - it's about finding solutions to complex problems as quickly as possible.
Which implies that someone with a low IQ would be able to find the same solutions to problems as someone with a high IQ (given enough time). This means that IQ tests don't measure cognitive abilities, only the speed of them.
@@paulknight9998 Thats what youtr iq is. If i tell you to build a house And you do ot the fastest you probably have the higgest oq causr you solved the problems fastest. everyone will eventually build the house
@@jamesowens7342 this is a terrible example.
Wrong. Not just about speed. Less iq has far more limitations. You can give low iq all the time in the world they will not discover a lot of what high iq people have already done
I've always said this. It's why many professionals like doctors, lawyers, etc. seem smart in their field but are in all actuality very dumb people. A good memory will get you through college, you will read and regurgitate, and as long as what you parrot is correct information you will seem smart. A person with high IQ can forget how to do a task after every time they do it and just figure it out by coming up with a new solution for the same task multiple times.
"Too far afield is actually one of the names of this podcast."
You come out with a lot of great one liners Lex. Very entertaining.
9:28 intelligence is not just the ability to memorize fact but also the ability to manipulate information to get at a novel and useful result.
They are not mutually exclusive but I think that being curious is just as important as having a high IQ. The thirst for knowledge is its own reward.
Jordan Peterson talks about being high in conscientiousness and being industrious. There are also other sorts of talents (or intelligences) that you can incorporate with some stick-to-itness.
My curiosity is asking if these things are mutually exclusive. Having a high IQ is correlated with curiosity. People who can learn easier would likely have a bigger thirst for knowledge.
Just throwing this out there. I have no empirical data but my observation is your average highschool dropout isn't exactly an avid reader.
You're pretty much saying that it's good to have abilities but you gotta use them properly
Re: Recalling backwards, I read something a while back where the great Greek philosophers would challenge each other by first retelling the events of their day from waking up to turning in, then after completing that cypher would retell the same day backwards.
I tried remembering every single detail and that was hard in itself. Going in reverse would make my brain crash.
That’s awesome.
Very informative. On the topic on reaction time, perhaps this is why FAANG interviews are so caught up in having a time limit for their algorithm challenges. It’s intense on the interviewee but as Richard mentioned, it’s a way to put a spotlight on those who process information quicker.
This is fascinating and I agree that quick calculation is correlated with intelligence, but I don't like how people who may be intelligent, but process slowly are often overlooked/omitted.
Malcolm Gladwell did a great look into how a minority of brilliant people are essentially cut out due to timed testing. There are some people who can calculate the best answer to more problems than certain people who calculate quickly. The former may get a worse score when timed in testing purely because they aren't as fast.
There are lots of benefits to failing faster, such as iterating more, and learning faster. It also allows for more productivity, especially with productivity enhancing tools like computers.
So optimizing for that can over the long term have compounding benefits on the individual level.
At the same time, being faster doesn't always mean finding the best answer, but it often means finding the good enough answer. The world runs on good enough.
@@NdxtremeProSpot on. As someone who is a top student in STEM field, but "process slowly", I've always been jealous of students who finish the test in 20 minutes and make mistakes, but it's still "good enough" for very high grade. I waste an hour more and get barely a few % better result. That's how I quickly realized I wouldn't be able to touch those super high IQ people if I was having a challenging time limit.
@@Magihyun That actually sounds like you could forgo some accuracy to get their results, but you have higher standards than them. Of course, I can't know that for sure.
@@Magihyun a good tester will recognize this.
@@NdxtremePro @Magihyun @Caleb Seems a quality such as speed is not about intelligence but moreso about shaping expectation toward navigating a fast pace world. We have a level of general AI that will excute most if not all such test in fractions of a second... 2 things about that; 1) I'm sure that the Deepmind team and probably other teams are capable of building general AI that will score off the charts (only because of the speed of the answer); 2) seems in the measure of AI, speed only addresses comparative performance, not intelligence. Ergo, wouldn't we apply the same logic to human intelligence/performance?
Adding a time limit, though, also provokes a stress reaction, which can worsen the performance.
The most difficult IQ tests that aim to measure way over 140 indeed don't have a time limit at all, e.g. The Titan Test, Mega Test, Cooijmans Intelligence Tests Form 4, etc. Even the most intelligent people spend weeks on them because the items are way more difficult. These are better at determining raw power of thought.
I've had two neuropsychological evaluations, both took 5 hours. They are a fascinating experience.

What went down ?
And? What happened?
Where do you do one of those
@@123mcgarrigle incorrect - depends on start of proceding word, an fascinating is a stupid thing to say.
The MMPI was given to nuclear power plant workers that had access to critical systems. If there were any red flags from your response, a psychologist would discuss it with you before his evaluation. I took it a couple of times without incident. One person I worked with answered “yes” to the question, “I like unusual sexual practices” which naturally piqued the attention of the psychologist. When asked to elaborate by the psychologist, my coworker admitted that he liked the doggystyle position. The psychologist told him that that was not unusual and passed him. I suggested he should have added “while dressed as a clown” or some other bizarre answer to see the psychologist’s reaction.
😂
Seems intrusive, thus begging a response that will make the inquisitor regret asking it.
I spent most of my life thinking I was below average intelligence because school put me in a special class when I was 9.
At age 50, I took my first IQ test and the result was 120 = superior intelligence.
Oh wow, imagine what I could have achieved if I believed in myself. School messed with my head.
Mine is 138 and i don't think i'm a genius but man I see a whole lot of low IQ people in the world.
This aspect of time is interesting, I wonder how general this is, because I know some people who will take their time thinking about a question or problem, and respond with a brilliant answer or solution, and others that will respond near instantaneously or come up with say a programmatic solution very quickly and although relatively sufficient, the longer processing method wins out in the end almost every time. And I genuinely find the slow thinkers to be some of the most intelligent people I know.
Because they are not always slow… they think so many things during the “long “ time they think and for this reason their reasoning is much more solid.
Not only that. The fact that having something timed can contribute to anxiety and not thinking clearly means the system has a pretty big flaw. Imagine for example having someone hover over you as you write, draw,...etc you probably wouldn't do nearly as good of a job.
Interesting that you bring something like this up. What I wonder is whether or not the "slow thinker", if required to, would be able to produce a good enough solution instantaneously - something workable - while also slowly thinking about the better solution in the back of their minds. I think the real unicorns in society are these people who are able to produce good answers in high-pressure, time-constrained situations and brilliant answers given a bit more time to process things. I think from a young age people tend to lean too far to either side of these ways of responding to problems and hard-wire their brains into either one of those types of "problem-processing" so to speak. I hope I am making sense lol
The most challenging IQ tests, such as the legendary Titan Test, Nemesis Test, or Mega Test, which have ceilings reaching up to 190 IQ, are indeed completely untimed and still hold substantial validity. These tests are specifically designed to identify the "most intelligent individuals" on Earth. While they are not employed for clinical purposes, such as detecting learning disabilities, they are intended for individuals who are already aware of their high intelligence and seek to further challenge themselves intellectually. Conventional IQ tests cannot differentiate effectively beyond 140 IQ points. The absence of a time limit does not imply that anyone can easily solve every question, as the questions themselves are exceptionally difficult.
I was STUNNED to learn this man wasn't keeping up on the Depp-Heard trial...
lol
Yeah really! Yet we are supposed to marvel at his presentation? Give me a break..
I am currently finish my MS Thesis on Machine Learning Applications. What this man has refered to as "dustbowl empiricism" is exactly what is done in most of Machine Learning projects: look for the propper features that best describe your dataset, typically by means of Principal Component Analysis or something of that nature, and then apply a clustering algorithm to those new features that might not have any meaning per se. This is just gold, finding that it is a philosophical approach to clustering. Pure gold to me at this precise time.
I wonder if those who work in IQ field need to have a high IQ? Imagine working there for years, and one day you learn that you have an IQ of 90
The overage IQ of PhD holders is around 132, with college students' being at 115, and high school graduates at 105, so that's highly unlikely.

@cjwaves. I assume it's based on 'the data'
Many years ago! Before computer testing, I was given a multi copy paper test for a wry technical job interview as the first step of the selection process at this office…
After answering a few questions and noticing that there was 2 or 3 sheets attached together I peaked at the inside of the last sheet (it was glued at the long edges only) and saw that the last sheet had the answers to all the questions!
First thought was, why are they including the answers in this test? Is this a trick?
Then I realized that maybe it was just a convenient setup for the company to check the answers! Well, after the test and interview I left. A few days later they informed me that I had the best test results and they want to hire me…n
Sorry! I don't have an IQ high enough to understand you comment...did you copy the answers or not?
I don't understand the relevance of this story. So you cheated on the test?
@@syzygonal IQ test is useless and pointless.
@@Tethloach1 I don't think that was his point. If that was the point he was trying to make, then he failed. A test is not useless because it was administered poorly. That doesn't reflect on the efficacy of the test but the imprudence of the test's administrators.
Why am I so nervous watching this?

Intelligence is like money, some people are very rich and you'd never know it. Some people like to think they are rich too but are just in debt.
What about someone who you can tell is very rich, but wastes all their money on useless shit?

How would you know an untimed IQ test was not accurate unless you timed it and if you timed it, wouldn't that just prove that someone is faster? Or are you saying speed is synonymous with IQ? And would that theory hold true if the slower person solved more complex problems?
Speed of processing information is a great indicator of intelligence, someone that processes easier tasks slowly is unlikely to process harder tasks at all, so your point is redundant
It appears that test-taking speed is not so much a component of g (general intelligence) but rather lies in the non-cognitive personality domain and correlates positively with the trait of extraversion. Indeed, the most difficult IQ tests (High Range IQ tests) that aim to measure IQs up to 200 don't have time limits at all, for example, the Titan Test or Mega Test. Even the most intelligent people spend weeks on items. Here, the depth and power of thinking is measured, which is most important. The absence of a time limit in these high range IQ tests do not lead one to score higher than one is actually capable of because the items are hard enough so that only people who can actually solve them can solve them. If you believe timed tests are underestimating your IQ, then try some High Range IQ tests. Paul Cooijmans, founder of the most exclusive high iq society, the giga society, offers the best high range tests.
@@CountOfWoodlands okay, no time limit on the tests you recommend , I have no idea if I'm underestimated or over, I just like comparing patterns, it's fun for me, thx for the response ....
@@dukelee3964 For example, Cooijmans Intelligence Test - Form 4E. Test can be obtained on "iq-tests-for-the-high-range". The test fee is around 20 dollars/euros. However, the test constructor Paul Cooijmans is pre-eminent in his field and is striving for best quality, so don't worry. There is no flashy website or big marketing to get attention.
Processing speed of a computer is an analogy for the speed of processing for an intelligent mind. The ability to take in input, processing it within seconds to give useful output/information. This is the reason why I believe an intelligent mind is a brain full of useful schemas and framework, on which subsequent input can be tied to, interpreted, analyzed to give meaningful information/output. The question now is- can schemas be enhanced?
This is an incredible suggestion… but I suppose that’s what a life time of education really is. Enhancing your tools for understanding the world. Did previous civilisations realise the benefits of base 10 number system over previous systems. If they had, maybe advances would have been made quicker. Just one example.
I’m sure there’s more nuance to be had here.
@@lekudos cn we discus otsyd of YT pls?
Exactly what my first thoughts were when I realised that speed of processing, and mental bandwidth are crucial components which increase proportionally with one's brain output/power. And yes, building frameworks, outlines, personal analytical patterns, employing systems theory and systems thinking etc. is key to enhancing your brain's processing power and drastically boosting your long-term potentiation over time. I personally believe in building a "2nd brain" and using it to exponentially increase your mental bandwidth. I tried adding my cntc de. tai. ls but yt deleted my comment....

"Doing well at task A correltates to a higher G We test for G using a set of tasks that includes task A. Therefore scoring well at task A correlates to a higher G" well it would, wouldn't it? Circular argument - I think there's a better phrase for it.
Yes doing well on task A correlates with G. But the way that G is created is that doing well on tasks A,B,C,D,E,F,H,I,J,…. also correlate with G.
The island of talent phenomenon, for example when we see a profoundly mentally retarded person with perfect pitch and perfect memory for music is actually very rare.

As someone who likes puzzles I did a IQ test online once and it's like the best kind of puzzles ever I highly recommend !
If IQ measures speed of processing what measures maximum attainable speed, it looks like iq is a test of the minds torque, but if we were to give a series of questions with no time limit that got increasingly difficult so as not be able to Solve them within the standard measures of time allocated to traditional IQ tests, would people who do well on IQ solve these problems any better than most of the population
Iq tests measure speed of processing along with memory. The other side of it is fluid vs crystalized intelligence. Fluid intelligence is like a child learning faster and having faster processing speed than a senior citizen. The senior citizen has a lot more memories stored and should have a much bigger vocabulary as well as a higher information score.
There are such tests, called High Range IQ Tests that aim to measure IQs way over 140. There is no time limit but they contain incrediblly difficult items that also require the most intelligent people to think weeks about.
So chess can also be a measure of IQ? (holding information on different variations, finding the best variation, time management, etc)
This confirms to me that I have a modest IQ- I process slowly, generally. I usually need instructions reiterated, for example. This despite having done well in school, and ovcasionally coming across as "smart" verbally or in terms of written expression. But I wonder, if we of humble IQ can arrive at correct answers given time, why should those smart-and-quick folks be considered more reliable sources on general matters (assuming one has that bias)? Obviously, with complex or technical matters, it is understandable that a high IQ would be a great advantage.
Working memory and vocabulary which is essentially correlated with a diversity of known concepts. Pretty easy to understand why that would be two of the highest indicators for intelligence. Both of these things are improvable as well.
Two problems with IQ tests are that because they all have multiple mini tests within the test and each mini test is not equally valid at judging intelligence. For example there is one part of 2 of tests I have taken (both institutionally given) that I score 100 on. In test one, it is 1 of 4 parts. In test two it is 1 of 10 parts. This is my weak spot and it drags my IQ down. I score much lower in test one than test two.
I have also been told by people that score the tests, that generally most scorers think that certain parts of the test are much more likely to predict intelligence than others. If all 4 or 10 parts of the test are given equal credit in the final score, yet some parts deserve much more credit, then the scoring methodology is scientifically wrong. This would be easy to fix with a simple factorization algorithm and should be.
I have also found actual errors on some multiple choice questions. These were other choices that could have been added that would still be valid that spoiled the logic of the answers provided in the other choices.
I think that quickly admitting you don’t know something, while itself not necessarily an indicator of high I.Q., is probably highly correlated with it. I mention this because despite having an above average vocabulary, I did not know what ‘regatta’ meant either!
OK ... a little bit shocked Lex doesn't know what a regatta is... but very interesting indeed because it makes a point in what let's say the cultural knowledge makes for people to excel in life vs Intelligence, meaning empathy perhaps with a potencial boss in an interview, or just starting a conversation with a possible investor in your startup. This things truly matter in the way you connect and extract things from people and life into your advantage. I have varios friends that I regard very intelligent, almost genius, but they some lack social intelligence or general knowledge about culture. It is very interesting.... Lex BTW, you like music... Regatta de Blanc rings any bell? cheers from México.
Intelligence and wisdom are 2 different things, not to mention determination and persistence. Speaking of "intelligence" in the context of the video is strictly referring to the G factor, or the intelligence in your genes so to speak. The other things you can control, but you can't adjust your IQ in any way.

In my opinion, IQ tests do tell alot about how people are perceived by others (somebody who is quick to deal with new information and verbally fluent will be perceived to be more intelligent) and it certainly is useful, but it is by no means an accurate measure of a persons cognitive abilities/potential. There are many people who may seem to be a little slow at processing things, whether that be because they suffer from some form of autism or anxiety disorder, or maybe because they suffer from insomnia and yet will go on to change the world purely because their cognition is unique, and as of today, unexaminable.
Also, I did like the way this guy kept bringing the discussion back to the original question. Lex likes to bounce around alot and sometimes the question asked is forgotten or glossed over.
"but it is by no means an accurate measure of a persons cognitive abilities/potential." i wish we coul save comments, this was very well said
Amazing reflection!
@@GameOgreDonkey Do you think a great metrics to calculate intelligence is how much positive value one has created for others past a long time?
every challenge will always have some structure to it, thus prior familiarity can never be eliminated as a factor in solution finding. nothing is innately novel
Very clever lex to save the best part of the info until the end of the clip. Lol you bastard!
If someone wasn't exposed to information like as an example, fibonacci sequence, yet on iq test can recognise and generalise the sequence, yet someone who's been better educated and exposed to that information has only to recognise and memorise the rule.. So how can that be a exact analysis of intelligence (repeating learnt information compared to critical thinking)?
Nature or nurture?
yup, a good test will try to measure fluid intelligence more and minimize the influence of crystallized intelligence, stuff like culture-dependent knowledge. Yet fluid intelligence is dependent on nature as well as nurture, probably not to the same degree but they both seem important.
we can view the role of nurture either as nurture being insufficient compared to the possible limits of nature or the enhanchement of the very limited basic kit nature gives us, depending on ones focus. They certainly seem codependent though. Then again this could be a false dilemma, the seperation of the two does seem a bit questionable at times.
You have a good point, and knowledge is accrued over centuries, so IQ test, imho, is just an elite's game.
Fascinating chat. Thank you
09:45 Hick's law, or the Hick-Hyman law, named after British and American psychologists William Edmund Hick and Ray Hyman, describes the time it takes for a person to make a decision as a result of the possible choices: increasing the number of choices will increase the decision time logarithmically. The Hick-Hyman law assesses cognitive information capacity in choice reaction experiments. The amount of time taken to process a certain amount of bits in the Hick-Hyman law is known as the "rate of gain of information". Source:Wikipedia/Hick's law
Fascinating. Thanks for the tidbit to send me off to learn more of this. 🙏🏽
I don’t like the vocabulary testing mostly because while yes, people with a higher IQ tend to have a broadened vocabulary, there is a chance that even a genius hasn’t heard a word before and there’s usually not very many context clues in a word to derive a definition. This is especially true with people who read a lot of books vs not with people reading having significantly broader vocabularies. You could say “people who like to read are usually smarter” but I would be very careful with that thought because it’s definitely not 1:1 especially with people who don’t have the patience to read a book but have high fluid intelligences. Number sequence backwards is useful. I think raven’s matrices is by far the most accurate predictor of fluid intelligence simply because it measures a persons ability to switch pattern recognition and problem solving methods quickly.
That point Haier makes pertains to the complex emotions that are expressed in the differential sequenses of human thought and emotions that hug and tug at I.Q. outside the bounds of the EGO experience of Life.
I appreciate Lex had put solvable puzzle on the preview. I expected a little trolling
Bro, I’ve been tested for IQ and luckily, the test results came back negative, which was a huge relief 😅
I’ve taken the MMPI. It’s pretty difficult to weigh the questions when there are valid arguments on both sides. I had to reason it out in my thoughts and decide, X > Y or Y > X? I prefer essay questions where I can describe my thinking process in order to defend my choice, but the test was fun, nonetheless. (I *LOVE* tests!)
I know exactly what a “regatta” is because it knocked me out of a regional spelling bee 50+ years ago! I’d never heard of it so reached into my experience and came up with “ricotta” - you can bet I’ve never forgotten how to spell *REGATTA* since then!

A rare time you see Lex interrupting his guest for a whole long minute, basically to say that yes he's heard about the MMPI test
I've hired/interviewed a lot of different people while working as a software architect and as a consultant. Personality, previous experience, etc, everything just pales in comparison to intelligence and industriousness. Intelligence definitely coming in first place. Because intelligence is exponential, someone with 130 iq learns many times faster than 115 iq. Same thing with 145 iq vs 130. No one wants to spend 10 times as long teaching someone.
form where you have the info it's exponential? it just can't be true and i think it's easy to be proven
The answer to the question in the thumbnail is 1, 3, 5, 6 and 9 if you think of the grid as being numbered 1 to 9 and the answer being the blue squares.
There is twist somewhere, an individual under Dominic O'Brien mentorship would be able to recite those numbers backwards and forwards, does this not cloud the true intelligence assessment, giving a false positive? Or showing that performance on this item of an IQ test can be enhanced?
I think IQ test have gaps that do not measure certain aspects of intelligence.
For example long term planning, deciding between a thousand choices by seeing the big picture, not just choosing from six pictures in a test, which you are limited for time.
What about long term memory, applying information you have aquired in an intelligent way to make a 'big picture' decision in the present to get the best solution in the long term. What about using all your acquired long term knowledge to merge learned information to form creative solutions to a current problem, or even just to make something unique and creative like a work of art, or an engineering masterpiece. IQ tests do not measure this which is a very important aspect of human intelligence that is used for the things that really matter in life, such as career choice, financial planning, family planning and more. There seems to be a lot of focus on speed in an IQ test which in day to day real life is mostly only beneficial for trivial decisions. I think this is probably why the majority of psychologists believe that an IQ score is not a true measure of overall human intelligence.
I think it is handy for measure certain areas of intelligence, mainly reasoning.
Regarding the light test.
You see this is another example that what we call intelligence is just Clockspeed:
How fast one thinks; which causes a subjective slowing of time. More time to process info and more time to make a decision.
It is not true that intelligence is mainly speed and that with enough time given everybody could solve and learn anything. This Dr. Haier is really freaking wrong here. In fact, the most difficult IQ Tests that try to measure IQs way above 140 do NOT have time limits at all (Mega Test, Titan Test, Cooijmans Intelligence tests), which, however, does not mean that with enough time everybody could score full points. Extremely high IQs are determined by ability to solve extremely hard items/problems, not by solving items quickly. When one cannot solve an item in a high range untimted test, it is because he is not capable of doing so and not because of strict time limits imposed.

I find it interesting that we still don't truly understand what IQ even means. It seems that (some?) researchers are still thinking it only means doing the same thing faster when doing the task requires some amount of processing.
However, I would consider true IQ as ability to more complex stuff than somebody with lesser IQ. That would require more and more progressively harder tests until the test subject no longer can complete any. I don't know if this would be called IQ in research or something else.
There are mental tasks that less intelligent person cannot do, no matter how many hours you give to complete the test.
Indeed, there are such IQ tests, called High Range IQ Tests. These difficult IQ tests (High Range IQ tests) that aim to measure IQs way over 140 don't have time limits at all, for example, the Titan Test or Mega Test, Cooijmans Intelligence Test Form 4E. Even the most intelligent people spend weeks on certain items because they are extremely complex to solve. Here, the depth and power of thinking is measured. The absence of a time limit in these high range IQ tests does not lead one to score higher than one is actually capable of because the items are hard enough so that only people who can actually solve them can solve them. Regular IQ tests with time limits don't have much validity above 140 because they lack hard enough problems. Also, It appears that test-taking speed is not so much a component of g (general intelligence) but rather lies in the non-cognitive personality domain and correlates positively with the trait of extraversion.
Lex made me feel better when he did not know what regatta was
Im surprised it took me that long to figure out the simple pattern.
Its just 1st pic and 2 pic added toghether in tows from left to right
Lex had been unusually proactive in this clip.
Where is the test? What site
We all have a limited capacities different from one to another & the successful one’s use their abilities to it’s limit & intelligence/environment/upbringing/opportunities are all variables.
There are brilliant people everywhere
2:51 Oh sounds like you are just making a convolutional neural network but on paper:
1) Each Washington vs Lincoln question is an image transformation that produces a pattern
2) Each resulting pattern is weighted together
3) That gives you a value that corresponds with a result
It's like trying to describe how characters 4 and 5 are different in such a way that the description would always be able to correctly differentiate them. The description would fill a book & still probably fail. BUT if you apply random transformations it would produce "scores" that would correspond with the right answer
I am total wortless of remembering numbers, tough I am pretty good to learn soo I think I could learn to remember like 12 digit numbers. But I supose I could do backward stuff to, but if they ask me to order them, I would be lost!
IQ is not what you know. It is what you have the ability to learn.
Cognitive capacity u mean!
@@akpabiomd9970 No. What I meant is exactly whAt I typed.
Ok
@@hyperretroactivehyperretro5992 I know thats what you meant , I was only validating your comment and giving the name psychologist call it. No offence!

I would have ask Haier about Ravens progressive matrices test. Would have been very interesting.
The difference between causation and correlation is crucial. If you have causation, you already have half of the scientific theory. Correlation, however, might mean something, or it might mean nothing. 95% of psychometrics is correlation.
At the beginning. The two nerds I love it
i have seen 100s of lex podcasts/clips but for some reason, this podcast was off. Anyone feel the same?
10:40 That's good as it accounts more for visual IQ.
When applying the Dust Bowl Empiricism method, wouldn't one need to use a different test to determine the disorder?
What a disability has to do with knowing what regatta means?
I visualize a phone dial and I can remember the pattern frontwards and backwards. Does that mean I’m a visual learner and is that cheating?
I have a 145IQ and it doesn't necessarily mean I'm knowledgeable in any specific field. There are so many subjects that I'm have 0 knowledge of and there are people who might have a lower IQ who are brilliant in that field. Most of the smartest people I know don't even project as "smart." A person can learn how to act "smart," but it's not that simple to recognize truly gifted people.
You can have high IQ and still be "dumb" but it's very unlikely unless done on purpose. What high IQ does is that you can absorb knowledge of a given field exponecially faster then someone with lower one and go beyond them. Example, having 100 IQ and play chess for 10 years, you will be most likely a decent one, but i can come in with 140 IQ never played chess and beat you consistently within a year and then you will never caught up to me.
@@redytor 10 years of experience will beat an advantaged IQ almost every time.
I must have 160 then no?
@@thug588 yeah maybe. It's all pretty made up anyway. 145 160 200 it doesn't really mean much.
@@VV-ku6bk so your brain is much more fail than mine
OF COURSE.
there's a weird question in my mind , if someone doesn't speak a language that have numbers for example the Pirahã people , how you can measure the g factor for them ?
Charles Murray and Richard Haier are expert academics on IQ. IQ is inherited and cannot be increased by any known method or learning program.
IQ is no different to other inherited human gifts, example sporting ability, eye-sight etc etc. It serves no purpose to promote specific inherited gifts. A sound philosophy is to teach that the QUANTITY of lemons inherited is one advantage but the most important thing in life is the QUALITY of the lemonade made froj those lemons. QUALITY lemonade manufacture is not inherited and in that regard everyone is EQUAL.

Wow really impressed Lex also considers himself a psychologist.
I always hated that aspect of IQ tests as I believed that with enough time I could work out every problem. But this indicates that all IQ is is just a measure of how quickly one can solve problems and not a measure of the amount of tools one needs to solve a problem as I originally thought.
I think it takes into consideration both if you can get the answer and how quickly
It has been found that when more time is allowed for an I.Q. test administration, the g loading of the test rises. It appears that test-taking speed is not so much a component of g (general intelligence) but rather lies in the non-cognitive personality domain and correlates positively with the trait of extraversion. Indeed, the most difficult IQ tests (High Range IQ tests) that aim to measure IQs up to 200 don't have time limits at all, for example, the Titan Test or Mega Test. Even the most intelligent people spend weeks on items. Here, the depth and power of thinking is measured, which is most important. The absence of a time limit in these high range IQ tests do not lead one to score higher than one is actually capable of because the items are hard enough so that only people who can actually solve them can solve them. If you believe timed tests are underestimating your IQ, then try some High Range IQ tests. Paul Cooijmans, founder of the most exclusive high iq society, the giga society, offers the best high range tests.
Now I can’t get those 6 numbers out of my head
Lol I've competed in Regattas...
G Factor is related to the G Funk, and that’s a whole new level.
How many kilometres from Washington DC to Miami? Let me tell you, there is small state in the southern most India called Kerala, with a population of 34 million, where quite a a big number of people have contemplated this question at some points in their life 😀
😁😁
How many kilometers from Miami Beach to Washington DC? That is a classic dialogue from an Indian movie. I must share this all of my friends immediately, that is so funny on so many levels!!!
I am interested to know what is. " excellent testimony " . To me its just testimony info to be weighted with all other info.
BTW on the thumbnail, add left to right
I knew what Regatta means..
big hello from Henley by the way.
I’m just trying to figure out what the G factor is.
I think the number backward test if more of a test of a person's ability to visualize a number in their head, as if it were written down. If you do that well, you just persist the image of the numbers list in your imagination as if if you "wrote it down" in your mind, and then read it back to front to response to the backwards test. If you persist numbers in your head in some other manner (looping audio, etc.), you will not do that well. It's a fun test for me because my ability to hold an image of text/numbers stably in my head is all over the map depending on the time of day, how I slept, did I eat tacos, etc.. Some days it's dead easy, other days that brain function is just "out to lunch".
So I'm not sure it's a good example of a transformation like doing a "letter jumbles" puzzles or converting a data set from one knowledge representation to another. For me at least, it's just a visualization stability test.
Imagine typing the number out on a phone, basically. But to be fair, Id wager even if they trained people to do that, the smarter ones would be better.
It is more simple an IQ test measures how one compares to other people in a group/population on a list of cognitive tasks. The resulting tests correlate somewhat to one's intelligence but not very strong. The test are getting better and better though over the years.
If you have a bucket that holds 2 gallons of water and another bucket that holds 3 gallons of water, how many buckets do you have?
In Perth Australia even the disadvantaged know what a regarta is, because we have the Masters Regatta where people make the boats out of old milk cartons and race them,
Yet you misspell it
Yeah, much happier, thanks

I have always been kinda slow, but when I did the wais IV test with a psychologist I got a high IQ because it separates processing speed into its own category. Does this mean that my intelligence is low in terms of g-factor? The psychologist suggested autism because I had such a large difference of scores between tests.
Maybe you have problem with your working memory
@@trongtue8384 my working memory was normal based on the test where you memorize numbers that is being read up to you
@@z0uLess so do you have problem in prossing thing ? Like the speed of your thought
@@trongtue8384 prossing thing? I have issues with not being able to generalize and I get stuck on details, I think, which the first sentence of this comment is an example of.
@@z0uLess Sorry if my writing is bad because English is not my first language.
But can you explain more about "not being able to generalize...." because it seem very fit to myself. And do it cause any problem when you study in school ?
I love to see Lex puzzled!
To paraphrase Forrest Gump, "Smart is as smart does."
The 'disadvantaged' people of West Virginia know what a regatta is. The Sternwheel Regatta in Charleston, West Virginia. "Ya Gotta Regatta," great slogan. The P.A. Denny was the Tiger Woods of regattas up and down the Ohio and Kanawha Rivers, by the way.

By saying "cultural" he also means "trainable" I guess?
