Top 10 Highest IQ Holders of the World

Article by ,

Intelligence along with street smarts is what is needed in today’s world. Intelligence Quotient (IQ) is a measure, a score obtained from a test, measuring a person’s intelligence or how sharp their brain works. These tests are for certain areas like language fluency, 3 dimensional thinking, etc.
IQ scores are used as predictors of educational achievement, special needs, job performance and income. The average IQ of the population is 100 as many score between 70 and 130.

World’s 10 highest IQ holders are:

10. Stephen Hawking (IQ 160)


Stephen William Hawking was born on 8th January, 1942 in United Kingdom. His IQ is 160. He is devoted to the core fields of science and have worked on gravitational theorems in the framework of general relativity, and many theoretical predictions on black holes stating that they emit radiations and known as hawking radiation. He attended Oxford University in 1959 when he was only 17 years old.

He was the first to explain the cosmology thesis by a union of the general theory of relativity and quantum mechanics. He is a vocal supporter of the many-worlds interpretation of quantum mechanics.

Stephen is a fellow of the Royal Society of Arts, a lifetime member of the Pontifical Academy of Sciences, and a recipient of the Presidential Medal of Freedom – the highest civilian award in the United States. He was also a professor of Mathematics at the University of Cambridge between 1979 and 2009.

9. Albert Einstein (IQ 160-190)


He was born on 14th march 1879 in Germany. His IQ was estimated between 160 and 190. The right handed physicist did his schooling from Germany. His devotion towards science started with a compass that his father showed him. What made him work was reason behind what makes a compass needle move. Apart from physics, he had a keen interest in mechanics and mathematics. He also applied for polytechnic colleges in Italy, but due insufficient grades he failed to get admission. On the advice of the dean of the same, as he had exceptionally high grades in physics and mathematics, he completed his secondary education from Switzerland.

He worked in the field of Quantum theory and was the one to develop the general theory of relativity which was the turning point in the field of science. He is also very well known for his mass–energy equivalence formula E = mc2. For his services to theoretical physics, and for his discovery of the law of the photoelectric effect, he was awarded with a Nobel Prize. He continued to work in the field of Quantum theory even after his photoelectric effect thesis.

At an age of 76, he died on 17th April, 1955 due to some internal bleeding.

8. Judit Polgar (IQ 170)


She was born on 23rd July 1976, in Hungary. With an IQ of 170, she is the strongest female chess player in history. She achieved the title of Grand-master when she was 15 years old and was the youngest to do so until then. She is the only woman to have won a game from a current world number one player and has defeated former world champions in either rapid or classical chess.

Her childhood went through a lot of struggle and chess as a specialized subject. Her father used to believe that if trained properly, anyone could be a genius in any subject. Believing in her father, Judit fought with the Hungarian chess committee as women were not allowed to play with men. Based on similar grounds, so was not given the title of grandmaster even being nominated many times. With 2 sisters in her life, her childhood went under complete specialisation of chess with them as his father appointed them for home schooling.

7. Leonardo da Vinci (IQ 180-190)


Leonardo di ser Piero da Vinci was born on April 15, 1452, in Italy. He had an IQ between 180 and 190. He is often described as the archetype of the Renaissance Man, a man of “unquenchable curiosity” and “feverishly inventive imagination”. He was extremely talented and dedicated to his work specially art.

He did an informal education in Latin, geometry and mathematics. His first painting was a monster spitting fire. His famous artworks are Mona Lisa, the Last Supper, and the Vitruvian Man. He was skilled as a painter, sculptor, architect, musician, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer.

He died on May 2, 1519.

6. Marilyn Vos Savant (IQ 190)


She was born on August 11, 1946 in United States of America. Her IQ is 190. She is highly skilful in being an American magazine columnist, author, lecturer, and playwright.

In her childhood days she used to work at her father’s general store and side by side she used to love reading and writing articles. Marilyn has got a local newspaper posting her work and she agreed to work under alias as she didn’t want to use her name for something at which she was imperfect. In 1986, she wrote for  a Sunday column in Parade magazine, wherein she used to solve puzzles and answer a variety of questions from her readers.

In 1985 she was registered into the Guinness  World records for having the highest IQ amongst women.

5. Garry Kasparov (IQ 194)


He was born on 13th April, 1963 in Soviet Union, Russia. He has an outstanding IQ of 194. He is a Russian chess grandmaster, a former World Chess Champion, a writer and a political activist, considered by many to be the greatest chess player. He began taking chess as a serious matter at an early age when his parents gave him a chess problem and he was able to propose a solution. He started his training at an age of 11.

He won his first championship which was Soviet Union Junior Chess championship, by the age of 13 years. In 1985 he won the first title of world championship in Moscow by earning twelve and a half points. He officially retired from major chess tournaments, on 10th March 2005. He also played against and got defeated by a supercomputer opponent that can calculate 200 million moves in every second

4. Kim Ung-yong (IQ 210)


Kim Ung-yong was born on March 7, 1963 in South Korea. By profession he is a civil engineer. His IQ as calculated is 210. At an age of 6 months he had started speaking. At an age of 3 he had learnt many languages like Japanese, Korean, German and English. And at an age of 14 years, he solved complex calculus problems on Japanese television.

3. Christopher Hirata (IQ 225)


He was born on 30th November 1982. He has an IQ of 225. When he was 12 years old, he had already done his college level course on physics and mathematics. At the age of 13 he won a gold medal in international science Olympiad. He was working with NASA on a project to conquer mars when he was 16 years old. He got his PhD from Princeton University and is currently teaching astrophysics at California Institute of Technology.

2. Terence Tao (IQ 225-230)


He was born on 17th July, 1975 in Australia. He has an IQ between 225 and 230. Being a mathematician, he specializes in harmonic analysis, partial differential equations, additive combinatorics, ergodic Ramsey theory, random matrix theory, and analytic number theory.

Terence is currently teaching at University of California, Los Angeles. He exhibited extraordinary mathematical abilities from an early age and knew basic arithmetic when he was 2 years old. He attended university level mathematics courses at the age of nine. When he was 15 he published his first assistant paper. He received his bachelor’s and master’s degrees at the age of 16.

1. William James Sidis(IQ 250-300)


He was born on 1st April 1888 in New York City. His IQ was estimated to be between 250 and 300. He went to a grammar school at an age of 6 and graduated within 7 months. He went to Harvard at an age of 11 and by the time he was adult, he knew over 40 languages. He specialized in the field of mathematics. At Harvard he was physically threatened by some students due to which his parents got him a teaching assistant job at Rice University in Texas. Being frustrated at job and being threatened by students he left his job and had a political career ahead. He died in 1944 due to some brain damage and it was the same reason his father had passed away.

    How can someone have a higher IQ than exists in the IQ system? Each IQ test has a maximum possible level, which those claims surpass, making them false claims.
    I.Q. is one’s score in a test of intelligence, tests which cannot give you more than a 100% on them. (There’s no extra credit.)
    From what I can tell, I.Q. doesn’t go beyond 200 in how results are scored.
    And, I just found via a google search someone who knows the history of I.Q. testing, who stated 200 is indeed the limit. He said that beyond 200 is unmeasurable. I imagine he means by the currently existing tests, which indeed cannot prove who is higher or lower in the intellectual hierarchy beyond it’s cutoff point.
    So, these claims over 200 are FALSE. Hearsay, and guesses do not count as facts.

    Most IQ tests only go up to 160, and the highest possible score is 200, which would be 100% score.

    They do only go up to 200. I’m in psychology of which IQ tests are a very prevalent part. I know a person very close to me who’s IQ is 165, also. I doubt this site can be a trusted source. More of an entertainment source than one for education.

    • AarOnTheBox

      MM, psychology, I love that hobby. Don’t you find it hilarious that some people think psychology is a science? Oh, and since you’re “in psychology” (not sure what the hell that even means other than the fact that its a good thing you didn’t study literature) I am sure you’ve noticed that psychology students are amongst the most pretentious yet naïve people on the planet? Especially considering an understanding of psychology or psychoanalytical skill has much more to do with IQ (see how tied that in there? did you like that?) and the ability to relate, sympathize and empathize, not draw large based conclusions and categories to pull individuals, who are almost infinitely more different and complex than a snowflake.
      Sure, you can study the “philosophy of psychology” and pretty much talk about that until you go psycho…logically insane. Of course, you can also learn how other people have decided they think psychology works, or you can share with others how you personally go about the process of psychoanalysis, but ultimately, psychoanalytical skills are more closely related to an art, or natural talent. Some people can study psychology their entire life and never be able to understand the complexities of psychoanalyses as well as a very intelligent person who just has a knack for such a thing.
      In fact, there are lots of psychological theories on what makes one good at psychology. Interesting, eh? But the most important word in that statement of course is: theories. Theories are all psychology has and ever will provide for us and ultimately, that is why psychology students are so annoying because they think they are actually learning something “factual” when instead the majority of psychology students (there are exceptions if they understand the nature of psychology prior to being spoon fed someone else’s opinions and then get graded (oh and you better get that good grade, because that diploma means you know what you are talking about) on how well you can parrot their own ideas back to them. It’s something interesting to think about.
      I mean, I guess the real proof would lay in the fact that psychology has not yet, and never will lead to a conclusion or one single fact that pertains to all people. However, why would it? Psychology isn’t a science. Now neurology, that’s a science. Psychology? Well, its a good way to convince people that you understand them than they understand themselves and, heck, if you can get a medical degree, you can also throw a bunch of useless pills at them, explaining to them that their issue is a chemical imbalance.
      Of course it is! My issue is that my brain doesn’t supply enough endorphins and my endorphin receptors are faulty so I need a permanent prescription for morphine! Too bad these silly psychiatrists haven’t bought it yet. Oh well!
      Good luck to you and your psychological…er…you’re being IN psychology…I am wondering if your name is Ms. Cho or Cholo or something and that’s why you are IN psychology.

      • IKnowThis

        I take the class merely for education of the subject. It is a hobby to me same as it is to you (as you make it seem). I don’t intend to create a career out of it. I don’t care about the diploma. I apologize for my syntax error. I was rushed for time and didn’t check it over, but you clearly still understood what was meant. I take responsibility for my mistake. I think faster than I type. Also, I never said it was a science. However, to me, it is a study (and in some areas, science) I happen to find interesting. Same as I find topics like drugs, philosophy, biology, religion, language, culinary arts, and the humanities interesting. I have my collected knowledge of each along with skills, and then some of others from various lessons along the way. Learning is what I strive for.
        I wasn’t aiming to start an argument. I just wanted to reiterate a fact previously mentioned, with background people may or may not trust. I’m sorry if I offended you by any means. That really was not my intention.

        What is psychology if not an science? there are only a limited ways to respond to every given scenario. This makes us able to study what way people will respond and get the same results from multiple instances, therefore we can create an understanding of how you get affected by the process and completion of any given situation thus we end up with resources to draw facts

        There are fewer smart people in this world, these negative comments and opposing thumbs you received are a great example of this. Look at how they praise the ignorance of their peers and continue to add more non sense into the equation as they gain support from other lesser beings. Stephanie Capalbo is a perfect example of this, 48 thumbs up on a thread based on iq and she ends it with a smiley face. Not to mention the useless comment and the flock of other lesser intellects who swarm her post with passion, since it is all they know, simple emotions rule their lives. As animalistic as they come, drawn here to this page because they too wish they could be like us. I know this you must be the most retarded person alive, casting doubt over the authenticity of this site with no proof or evidence.

  • Jon Opperman

    I had 144 IQ at 14, recorded and my HS counselor said the test didn’t measure above that. Took several private tests since high school; all between 178 and 182. Now I’m too old to care, since it is obvious we can’t either breed or teach such ability, and the greatest impacts on our world are determined by dunces…why should anyone else care about this stuff?

    • actionmanrandell

      i call b.s on the 178 or 182 its a proven fact that as you get older your IQ will be lower because all though you may have had an IQ 144 at 14 . that was your IQ for that age. it will always be lower as you get older

      • Jon Opperman

        Good to know you have this worked out. I’m a doddering old fool now and didn’t realize my faculties diminished over time. The numbers weren’t made up. My IQ at 19 was much higher than my IQ at 14. I honestly never aspired to be an anomaly for your pet theory.

        • actionmanrandell

          It is not a pet Theory its a verifiable scientific fact. and no one said you having a lower IQ when you are older means your mental faculties have Diminished. you say your IQ was higher at 19 than when you were 14 but thats a bold faced lie and if you indeed score a higher number on an IQ test then the test you took was a false test. your IQ depends on your age. the tests you take at say 14 are completely different than the ones you take at 20 or 30 or 50. if you took a test at 19 and your Score went up. the person who administered and evaluated your test did it incorrectly. for the simple fact is that test scores are different as you age

          • Jon Opperman

            IQ peaks in early adulthood. I surely spent less time finding this reference than it took you to formulate your trolling response. Apparently you place way too much emphasis on IQ and my post was a hot-button for you. Still, my post is an accurate account of my personal history.
            “The exact peak age of fluid intelligence or crystallized intelligence
            remains elusive. Cross-sectional studies usually show that especially
            fluid intelligence peaks at a relatively young age (often in the early
            adulthood) while longitudinal data mostly show that intelligence is
            stable until the mid adulthood or later. Subsequently, intelligence
            seems to decline slowly.”

            From wikipedia, referenced article:

          • neilinely

            How can you say it is a “bold-faced lie”? It is perfectly possible for one to get a higher IQ score at 19 than 14. Using your logic, a 14-year-old would have a lower IQ than a one-year-old. I’d like to see your results at ages one and 14!

          • actionmanrandell

            Wrong you are not listening you dipshit. when calculating someones IQ they use a persons age to determine IQ so an IQ of 150 at 14 is not the same thing as an IQ of 150 at 25 it simply isn’t if a person says there IQ is higher at 19 than at 14 they are a liar

          • neilinely

            First, there is no need to personally insult peoples. Second, liar is a loaded word meaning a deliberate attempt to mislead people through knowingly presenting false information. Thirdly, you do not understand how age is used. It is a factor insofar as IQs are relative to age but IQ is not entirely static and, whilst it peaks in early adulthood, it can be improved. Read Kevin McGrew, director of the Institute for Applied Psychometrics, visiting professor in Educational Psychology at the University of Minnesota

            It depends. First I think it is important to distinguish between at least three different meanings of the word intelligence. There is biological intelligence, or what is typically defined as neural efficiency. Then there’s psychometric intelligence – your measured IQ score – which is an indirect and imperfect method of estimating biological intelligence.

            Can you increase biological intelligence? Research during the past decade using various neurotechnologies (aka, brain fitness programs) has suggested that it is possible to fine-tune your neural efficiency, or mental horsepower. Your cognitive functions can be made to work more efficiently. and in a more synchronized manner.

            So can you change your IQ score? Individuals can change IQ scores. Your score may change not because of any real change in general intelligence, but that different tests may be used which measure different mixtures of abilities.

          • actionmanrandell

            you are still not listening. you can change your IQ but im sorry but your IQ will NEVER EVER EVER GO FROM 150 AT 14 TO HIGHER THAN THAT AT 25. OR ANY HIGHER AGE in every single IQ test. your IQ is determined around the number of answers you get correct and your age.there will always be a lower score as you get older because when you are older the tests are designed around your age. and as such you NEVER will have the same level of IQ lets put it this. if your IQ is 150 at 14 and at 25 you take an IQ tests. because the test is different. if you Score a 150 on said IQ that would mean you’re intelligence has increased. go take an IQ test online(there are tests out there that are very accurate) take the test multiple times putting in multiple different ages. you will get a different result each time. here is an even simpler explanation. when you take an IQ test and you are told you are gifted, or average, or above average, or a genius. they are determining that based on calculating how much your IQ is based on the average of every other person who took the same test at the same exact age as you. so if you get an IQ of 150(above genius) and you are 25. they are saying compared to every other 25 year old who took the same test. you are a genius. but when someone says they have an IQ of 150 they are half lying and half telling the truth. there is no way to judge the exact IQ a person has. there is a reasonable error around any reliable IQ and that error is going to be plus or minus 5 or 6 points, to give you a 95 percent confidence interval. So, for example, if a person scores 126, then you can say with 95 percent confidence that the person’s true IQ is somewhere between 120 and 132

            You can become a genuis later on even you were not one at the age of 14. What does even being a genius mean? If you feel like a genius you are a genius. Even better, if you take a test when you have an active state of mind void of worries, you will score better. My personal motto is to set your mind free of dictated knowledge. In this modern age, there is a huge accumulation of knowledge and one cannot grasp every bit of it. I personally think that some research areas are even diverged into rather unnecessarily complex paths. So what I do is to understand the gist. It is too easy to get lost in details. But if you are a genius you will have the ability to process given information without delay, in other words making necessary connections between pieces of information instantly. Otherwise, you will have to learn those connections the hard way. Sometimes you are in such a state of mind that you can understand even a rather complex thing in one shot. But, nobody will be able to stay in such a state of mind all the time even an IQ of 200. You are not born with an IQ of 200.

            LOL. I love how you keep on saying that people are not listening to you. They are clear responding to what you are saying giving links and sources saying that you are indeed incorrect. To your response that it is impossible to have a higher IQ. I had an IQ of 116 when I was in middle school. When I was a Senor in High School, it was 130. Both were given to me by the same psychologist and were given due to having ADD.

          • Autumn Rose

            Your IQ only goes down after the rest of your mental abilities decrease in old age. It is proven Brian function is linked to physical activity, if you stay in good physical condition when you are older (45 and up) your IQ will not drop too drastically. If you continue to mentally challenge yourself your IQ will also stay high. But you aren’t born with a set IQ and it drops as you get older, brain cell production slows as you get older. As children our brains are like sponges and for a time ou IQ will get higher and then plateau and then as we deteriorate our brain function deteriorates and the. Our IQ drops. Your IQ doesn’t drop every year as you age. That would be contradictory to survival as a omnivorous bipedal sentient being, fighting to stay alive in the food chain.

          • actionmanrandell

            it is not a fucking theory you dumb fuck

            an IQ is calculated by two means 1 the individual administering the test takes your age. and then takes the score of how many questions in the test you answered correctly and calculates said IQ based on age and test scores by definition an IQ score will be higher when you are younger. as you age it goes down because thats how it is calculated. for instance if a person has an IQ of 180 at 30. it would not have been 180 when he was say 14 it would have been higher. that is a fact

          • papa

            an IQ is calculated by age and test scores. you can not go from 150 to 175 on an IQ test. as you age the IQ score decreases because that is how they determine the score

      Some people need to check their grammar and spelling. The only time you use an apostrophe with the word “it’s” is when you are using it to mean “it is” or “it has”. There is no apostrophe used with the word “its” to show possession of something. If you don’t believe me, read here:

  • Onthebeachsyd

    The article does not mention the standard deviation used in determining the scores of these ten individuals and it is clear they are a mixture of different IQ measuring standards.

    For example the adult Weschler scale has a standard deviation of 15. This means a person with an IQ of 145 is three standard deviations above the norm of 100. The cut-off for MENSA is 130 (sd15) which is two standard deviations above the norm.

    No-one has a Weschler IQ higher than about 195. (6.33 standard deviations above the norm)

    Childhood IQ’s are measured using a standard deviation of 24. This means that a child with an IQ six standard deviations above the norm would have an IQ of 244 (sd24). (100+(6*24))

    The 2nd, 3rd and 4th highest scores on the above list are obviously not Weschler (sd15) scores but they are also not accurate childhood scores. All three individuals have scored 190+ (sd15) which would mean a childhood score of 244+ (sd24).

    Sidis was simply phenomenal and based on what he did as a child, as a teenager and as a young man had a higher IQ than anyone else in history, but was sensitive and succumbed to the pressure of being a publicly known ‘super-genius’. No-one knows what his IQ was because there was no way of measuring it.

    • jorge

      It has been my understanding that once you surpass the 200 mark in the Intelligence quotient test then you are compared against the greats to see where,
      beyond the scale range the individual would rank. Its all a projection of what it could be since the less intelligent are the ones coming up with the tests.

    i think they said his IQ was so high because he knew of over 40 languages and he finished grammar school at the age of 6(and a half) he is smarter then a person with an IQ of 200. you guys and gals here know basic languages he knew more then 40. most of you people say your IQ are high like 160-190.

    Any test does have a limit, for a standard IQ test, that limit is 200, Key word limit, a person’s IQ can be far higher than that limit (Though it is extremely unlikely) Putting it into terms, it could serve as a “check point” of sorts. I personally dislike IQ tests, they are not a accurate judge of intelligence, and even so, a person could have a IQ of 150 and contribute more to the world’s well being than a person with a IQ of 200. There is a member of MENSA, one of their highest ranking members IQ wise and they are a janitor. There is also the matter of mental and emotional stability to put into account. I’m sure that there are people with IQ’s in the 170-200 range but they just don’t give a flying F***.

    The comment section is for useful opinions, don’t insult others…
    …I agree that IQ tests doesn’t mean “Intelligence Test” literally. However is a fairly complete test to measure the intellectual capacity of a person. And finally the publication’s name is “Top 10 Highest IQ Holders of the World” not “Smartest people”…

    I was feeling judgmental about the author’s language skills at first, but I noticed that the errors seem consistent with someone who is not a native English speaker, or, it was badly translated to English from another language.

    This list is nonsense – my score is 161 so on that basis I should be in the top ten! Ridiculous list!

    • ryan evans

      less than 0.5% of the population has an iq over 140

      if your iq were actually 161 you would be at the very pinnacle of some field of study.

      it should be noted here that internet iq tests are complete and total bs

        Just cause your smart doesn’t mean you have to use it.

  • Arrin Stoner

    I believe that Da Vinci is somewhat overrated and should absolutely not be on this list. Granted the man was a genius painter (possibly the greatest) however, most of his drawings, sketches, inventions and other works outside of the realm of painting were taken from other less notable artists, engineers and inventors at that time. Due to his prolific skills at art his sketch books and other works have been embellished and glorified as if he was the genius behind these ideas when in fact he took these ideas from others and made slight modifications. Important to note, many of his “inventions” were impractical and never worked nor could ever work.

    I am only going to speak my piece (I am not opposed to a spirited debate). However, aggressive and insulting commentary are rampant on posts; frankly, I think they are written by cowardly individuals with ‘small man’ complexes for the purpose of bullying while safely avoiding a physical confrontation (a quintessential example, AarOnTheBox). Now, maybe IQ tests only go up to 200, maybe they don’t.
    First, I think that we can all agree that IQ and Standardized Tests CAN (not always) be indicators of eventual academic success & perhaps occupational success as well. But, to cut to the chase I think Einstein said it best, when he indicated that imagination is more important than intelligence. The most important factor is “what someone can do with their intelligence?” One may be a genius, be a member of Mensa, and attend MIT yet cannot tie their own shoes. That being said, there are others with “average” IQs that have enormous success for a variety of reasons: ability to think ‘outside the box,’ work ethic, or other creative faculties.
    My point can be summed up very concisely and perhaps is redundant: If you take the 5 individuals with the highest IQs in the world their intelligence does not mean a thing unless they are forwarding a cause. Example: solving difficult problems (say math, physics, what have you) that is actually relevant to explaining an important theory (or how / why something works), not simply because the problem cannot be solved by anyone else. The same would hold true with innovations. Steve Jobs is not on the list (I am guessing he had above-average intelligence), yet look at how his intelligence was applied through creative channels. I give praise to those with high IQs and those with ‘book smarts.’ However, when considering individuals at the highest echelon of IQs, one must consider how said individuals can contribute or apply their knowledge in useful, meaningful, and insightful/constructive ways. Thank You for Reading. kpn

    There’s a lot of different types of intelligence, therefore it is best to measure each of them specifically. IQ tests are not the proper measurement of our overall intelligence, because IQ tests don’t include all types of intelligence.

    I.Q test scores
    I tested at 89 in Elementary School, with not a hint of encouragement or an introduction to the very basics from my parents. I was tought to give up when things got tough. Constantly being reminded that I was a moron, I finally embraced the lie as a truth. I came to a few questions on the test that I had no answer for and decided to give up. Should one return to schooling either by home or private, I do believe a higher score later in life would be, no surprise.
    Employers often check applicants I.Q to determine if they are a good risk. I believe that in reality I am a 110 or slightly higher.

  • Mensa

    In Mensa Slovakia were publicied best IQ’s .. there were numbers like 200, 245, or lower 175 or highest 275 and I didn’t saw them here.. tell me why if on world are about 1 000 000 000 people that are having IQ 175 than why aren’t they wroten here? You know why? Because they are not popular of psychology, they are not the best mathematicians but they can be best in world in Biology.. you should think about better list …. They aren’t wroten here just because they didn’t went to Harvard??? reeeaaaalllyyyy???

  • dave

    My IQ is 140 and it means absolutley nothing. All an IQ test means is you are good at solving puzzles. My uncle has an IQ of 190 and he has no common sense. If it’s not in a book he is clueless.

    • papa

      I know someone just like this. He refers back to his mensa tests but sad to say many have said he lacked sense for success and thusfar has walked away empty-handed when it comes to business. He too is like a walking library but can only recite learned information and has yet to develop anything of his own. I think maybe they are excepting the creativity IQ which can be much more important to make change in the world. I think a good mix like Einstein can make such an impact in human history. Otherwise, what good is it when you can’t properly harness it or are missing some ingredients?

  • Kenneth Kleefeld

    An IQ of 300 has no meaningful cumulative percentile interpretation. On my IMAC using Microsoft EXCEL, assuming a mean of 100 and a standard deviation of 15, it is 100% out to at least 30 decimal places. Maybe some special tests can rank order the smartest people, but to label the results IQ is misleading.

  • Cmiuc Cat

    i think comparing to people of the past is incorrect… life was simpler, it wasn’t complex as today’s world is where there are a lot of challenges… and who is to say the testing was the same as it is today…

  • Jordan

    I have an IQ of 400,000.

  • jworryfree

    How low can IQ be measured? We seem to have many respondents approaching the low end of the scale. Plus can you measure anger?

  • Anum Anjum

    walter o’brien has an iq of 197 and should definitely be added to this list, he is a online personality, a hacker, as well as the ceo of a major computer service company called scorpion, and the reason i would like him on this list is because his life was put into a tv show called scorpion.
