      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.

    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.

    • @NdxtremePro
      @NdxtremePro Před 2 lety +23

      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.

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.

      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.

    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.

    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.

      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.

      @Santon-Motho Před rokem +1

      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

    • @CountOfWoodlands

      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 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.

    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

      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.

    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.

  • @Veggamattic
    @Veggamattic Před 9 měsíci +1

    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.

    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.

    • @Nestoras_Zogopoulos
      @Nestoras_Zogopoulos Před 2 lety +4

      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.

    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.

    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.

      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.

    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.

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.

    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.

    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.

    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.
