The other day I sat down to watch The Princess Bride for about the 10,000th time. Man that is a great movie! Anyway, when I was watching the part where Vizzini, the Sicilian, was answering the question as to how smart he is, he said:
“Let me put it this way. Have you ever heard of Plato, Aristotle, Socrates? Morons.”
So, I decided to mosey on over to the Interwebs and find a list of people with the highest IQ ever measured, and lo and behold I couldn’t find one! So for the sake of future searchers, I compiled the following information. Enjoy.
Background Info
In order to establish a baseline knowledge, IQ (intelligence quotient) is a score derived from attempting to measure the actual mental horsepower of any given individual. Personally I place little value in IQ tests, but I do acknowledge that they are an indicator of some common potential success factors, so we’ll leave it at that.
The “average” IQ is by definition 100, so if you score below that you are dumber than average, and above it means smarter than average.
Commonly acknowledged IQ Score Ranking System:
I’d like to stop for a second and inject a little philosophy before we go on. I have absolutely no respect whatsoever for intelligence. I only respect people for their actions. So no one should envy or emulate people on the list that follow because some of them are miserable human beings (like this narcissistic guy). Take Bobby Fischer as an example. He’s the biggest A-hole on the list, and I’d like to kick his teeth in for his comments about Jews and America.

From the Past
In 1926, psychologist Dr. Catherine Morris Cox – who had been assisted by Dr. Lewis M. Terman, Dr. Florence L. Goodenaugh, and Dr. Kate Gordon – published a study “of the most eminent men and women” who had lived between 1450 and 1850 to estimate what their IQs might have been. Data from that study as well as other sources around the net were compiled to form the following list. Please drop me a comment if you have additions or corrections (make sure and cite sources).

Test YOUR IQ
Now that you’ve read all about these really smart people, surely you want to know how you compare? Well, set aside a full 40 minutes and go through this test to determine where you are on the evolutionary chain.
Select the image below and the clock starts when the test loads, so be prepared in order to get the full 40 minutes. Trust me, you’re gonna need it! Oh, and if you answer “A” on every question, you get a 72! (a=72, b=65, c=65, d=65, e=72, f=72, g= 65, and h=65 – Only The Man would help you cheat on an IQ test!)

EDIT: I received the following e-mail from Mike, a former school psychologist of 30 years, regarding the validity of this IQ Test:
…one of the better and possibly fairly accurate IQ tests (11/8/07) seen on the net. Two caveats:
1. This test evaluates visual spatial reasoning skills, and not verbal which some may say would be a bias toward guys.
2. This test does not assess processing speed and ability to make quick/accurate and perhaps more c creative choices.For different view of intelligence away from IQ try: Theory of Multiple Intelligences
If it turns out you are a Genius, join a club! Here’s how to hook up with your intellectual peers:
- The Genius Society
- Mensa International
- International High IQ Society
- Poetic Genius Society
- The Mega Society
- The Triple Nine Society
By the way, why is it that most of the high IQ society Web sites suck so bad? And if I may inquire additionally, why is it that none of them have sections on their sites where they are actually teaching people by translating highly complex issues into understandable language?
Now, for the rest of us (I score just above a moderately intelligent canine, but just below a porpoise), you can just join the One Man’s Blog Society for the Incredibly Average. Believe me, we have a lot more fun around here.

I took this test quickly at work. Completed it in a little over 10 minutes. (dont wanna get caught goofing off ) :). scored a 122, think i could do better taking my time with a pen and paper but im still happy with that “Very Superior Intelligence” score :)
I ave fund that By tking these tests and sckring very low I am eleigibly for governt assistances. Smrt peple nevr get this usistnace. Thaz weh they have nu muny.
Lowest IQ everenecne
me
u make me fell stipid. how can u be so samrt and not care anbot is not so smrt/. I wish I was smart lwek yuse.
lol, Superior intellect really got you a great job; working in an office. Iq tests are nonsense, the fact that people can improve their scores through practice demonstrates that if someone were to have more exposure to IQ like problems before taking the test, it could have huge affects on their scores.
You’re right. No test can accurately measure how “intelligent” a person is and there are a lot of factors that can contribute someone to get higher or lower score. Anyway, I haven’t taken it yet… I hope I don’t find myself as a dumb after finishing it, I surely couldn’t overcome for a while XD
Who said working in an office is a great job? I am a CPA and have an MBA, and I hate working in an office. It’s boring and the computer glare is killing my eyesight. I love it when I have to travel because I get to meet and engage other people outside the darn office. I guess it depends on who you ask.
no one got a 199 or 165… if you do the test the highest you can get is “above end 160″ with a standard deviation of 24.
and also once you hit around 15 your not going to increase your iq score by very much. iq cannot be increased by reading or studying, its all about relationships and fluid intelligence. the only thing you can really work on is concentrating better…
im 16 and i got “above end 160″ with a standard deviation of 24. evidently I’m smarter than George Washington, which I do not believe to be true in the slightest. But even if I was, he was not the man we know today because of his iq. He is the first leader of our country because he fought for his beliefs, was true to his cause and hard working. He also had great confidence, which is why people had no problem putting their trust in him in their time of need. If you do not have an iq of 180 it does not mean that you cannot change the world, it simply means you had to work harder to get to the point where you can change the world, and will end up being a greater leader (because of character and experience) than someone who rides through life on the coattails of a lucky break.
meant that as a post… obviously my computer skills could use an iq boost as well :P
If you rushed through it like that I have to think that you would be able to improve by at least 5 points just by taking your time. Though I’m not sure it’s valid to take the same exact test twice because of the whole knowing the answers thing in advance. :-)
It would be funny if someone were to take this test like 5 times in a row to see how high they could ultimately get though.
John
yea, that would be cool. but i didnt notice, if i did say, which ones i got right and which i got wrong. So retaking it wouldnt be too bad ;)
I was surprised to see James Woods so high up there. Ive alway heard how smart he was, and i know he’s gotten in hold em poker big time latey (and supposedly he’s really good at it). But i guess i just dismissed it as media hype since he’s an actor.
I got 133 and I think I understand each question can’t really tell why could I be wrong at any, as I understand each one of it. I think they are wrigth, I love puzzles I’ve never consider me super smart or anithing. I write music so easily without ever studing music, as many other things I’ve achieved by my self so I wanted to see if there was something different about me and it seems I’m a little bit different, so I suggest to every one to do what you really enjoy be passionate about it, I’m pretty shure that this test can’t measure not even a bit of our potencial. I’m Mexican by the way :P greetings!!!
It is really bothering me seeing all these people saying they have scores such as yours, 133, and your spelling of many words through this are ridiculously misspelled. It is disgusting. Either this test is bull or you are lying.
i think it’s both.
Grammar has absolutely nothing to do with this test! Einstein had speech disabilities. So… That is why people with your IQ are never taken serious. The crazy thing im going to tell you is over 23 million adults in USA have some form of illiteracy.
i had to take a special test with a psychologist when I was 6 years old and whatever crazy potential I was diagnosed with, I am still a terrible speller. Why? Because I never put any effort in spelling. Spelling is realy only memorization, which believe it or not, is not a big deal IQ tests if you never made the effort. Some of the greatest composers had very high IQs. Music does not have much to do with spelling and so my point being, spelling has practicly nothing to do with IQ.
Or perhaps the fact that he’s a Mexican should’ve tipped you off that he’s not a native speaker. If he’d written in Mexican I’m sure the spelling & grammar would be better.
The test isn’t accurate. I got a score of 140+ without cheating, and I’m fairly certain I’m not that intelligent. Most people can get a good score if they take their time. (So you aren’t different after all.)
Oh and it bothers me when people brag about things like this and feel proud of themselves for it. And also when they’re arrogant about it.
You are right. I took a test at a Coutts Outplacement Agency conducted by a professor of psychology and score well at 153. One area on its own placed me in a genius category. I told one person, an old work associate, and immediatelt felt as though I was bragging. People I currently know have no idea I have that IQ level and I feel it is best I keep quiet about it.
@billtboy, I know the feeling. At 7 years of age, my brother and I were part of psych class study that our father was assisting with. While we both scored high, I know that I have lost about 24 points over the 35 years between tests. and scored just 2 points higher than yours :( Does this mean I am getting more stupid with age? Although to be fair, I do math type puzzles and crypto-type puzzles in my spare time. I never got a degree because I have no drive, but people around me keep trying to push me to get one. It is just not me. Having said that, I can do anything I set my mind to, from cooking and designing clothes and sewing them, to electronics, engineering design mechanical skills, although I tend to try for perfection and tend to get too focused on the problems, to the exclusion of eating and sleeping (am I a bit anal about it? probably). Same for reading and all the errors people make in papers and magazines, let the ones in books. What is needed is a test for potential (a “drive” test?). Who knows? That is for those smarter than me :)
IQ does not neceassarily mean you are inteligent, it just indicates the capacity at which your brain can learn, or process information, which consequentially is directly proportional with the speed at which your brain learns. I’m 9 and my IQ is 166
It’s like being smart is a disease, an affliction. You know, when our kids are in the gifted programs at school – they are actually a part of the special education program. That’s not exactly such a far cry from the truth. I have a few uber smart people in my life, and being so smart has presented many challenges for them. I used to be so jealous, but, now I’m happy as a peach in the Average Club!!!
We can’t go looking down on the idea of extreme intelligence, that’s a direct invitation to the dumbing down process.
I take these tests once or twice a year for the fun of it. My scores are always worse than the last one.
I wonder how Kim Peek would measure up to all of these people if they could find a way to accurately test his IQ. Is knowledge intelligence? Would Kim Peek even be a candidate for this list if the knowledge known has to be fully applied (as in using the knowledge in engineering, etc..)?
You don’t know reading a page of web ? Swedenborg = 205 IQ
Hi
Could anyone please tell me what’s the meaning of different results of the test?
I’ve just take the test, and I don’t understand whats the meaning of: Above end 140, above end 130 above 160 which appeared as my results according to different deviations..
Thanks
That’s part of the test.
My score always varies wildly with these online quizzes (from 110 to 155), while the test I took when I was in grade school put me at 143. Isn’t the reasoning as to how one arrives at an answer more important than an answer? Shouldn’t that be what IQ measures?
I thought that test was very much slanted to people who think well in spatial relations. I scored a 99th percentile in Spatial Relations on the ACT test back in the day and a 25th percentile for Clerical Speed and Accuracy. Someone like me would do well on this test but would look mentally challenged on other tests. I got through this test in under 15 minutes and scored high but sub-mensa which is a good thing based on my boyhood chess heroes life.
I think this test actually gives you a score somewhat lower than your real IQ. If I remember correctly I got 128 the first time I took this test (years ago). I recently took a supervised culture-fair IQ test called FRT (Figure Reasoning Test) with Mensa, and got an IQ of 135 or higher (135 is the ceiling).
I ended with 127, 129, 143 for the different deviations. I was measured twice when I was 10 y/o and got 142 and 143 then.
Oh, and i finished the test in just 9 Minutes. Couldn’t afford more time, cause I’m at work. I had to “skip” more difficult questions by answering by feeling… So I think, it’s not too bad :-)
I got 160 acording to the last deviaton and scores around 140 around the others were at my highschool i was tested and ended up with 166 on both tests they gave me i also did the test in just under 10 minutes thinking each question through so im not sure whether this test is accurate or not
And you the Man, what about you ??you look so smart!!!” I’d like to kick his teeth in for his comments about Jews and America.” I don’t agree with Fisher, but not more with your comment!
But at least your right:Specialization is for Insects…small,small insects!
Stephane,
Well, I make no claim to greatness. When it comes to mental prowess I have little more capacity than a squirrel. And apparantly, as you point out, I also have an overdeveloped Medulla Oblongata that makes me act like an overly agressive monkey. :-)
Hmmm. Do you think the fact that I want to kick someone’s ass is inversely related to my ability to be intelligent? If so, I’m the dumbest man on earth. Because I often meet people I’d like to smack.
John “dumb as a box of hammers” P.
As far as I know, IQ is your ABILITY to learn, not what you actually achieve, know, or what position you have in life. Knowledge, on the other hand, is something that is acquired. You don’t know jack when born, but acquire knowledge as you mature.
The subject of over/under achiever often includes references to IQ’s.
As a 5 year old child, I tested genious (like 167 or something). Did it again as a 17 yr old. And again did when 28 yrs old, and 3 sheets to wind (I.E, drunk as a skunk).
But I’m not a millionaire, nor someone of significant importance – though I do make good money and am very good at what I do.
So what’s the real relevence of an IQ test? Acceptance into a club, bragging rights, ??? Who knows. Those who work hard, and achieve, are the people I look up to. Not necessarily anyone with a high IQ, because it’s not your ability to learn that makes a successful person, but someone with the heart to battle and win. I choose that person to look up to.
‘because I often meet people I’d like to smack’
BwAAAhahahahahahah!!!! That was rich. I feel that same way – though I wonder if I should be smacked myself too often, as I’m definitely a ‘learn the hard way’ type of person, just can’t believe advice until I get my ass kicked (figuratively or otherwise).
Great comment!
The original tests were designed to get a sense as to which students could be be put ahead in school and which needed more help. It also served to find potential for an institution with out much investiture.
Some thing interesting about all the groups you posted and most around the internet is the tests they accept aren’t intelligence tests exclusively. The SAT for instance is not an intelligence test as it is only testing knowledge of the subject. While linked to intelligence if some one of very high intellect never goes to school they will not get a high enough score and conversely some one who memorizes the material perfectly could have an average intelligence but still get a perfect score. Given the original intent at that level of intellect the tests are going to be fairly unreliable anyways. Even then why would I want to be in one of these groups as many of there members would be people who wanted bragging rights and took the easiest test and reported it.
All in all at the really high end of intelligence tests mean little and the only way to get a handle on somebodies intellect is to talk with them. “actually teaching people by translating highly complex issues into understandable language” while I agree that would be a useful source the point of these groups seems to be bragging rights and interaction with peers not the demands society asks of those perceived intelligent.
Ok, my score was 105. Although, as in life, I am never swayed by conditioning or statistics or by anyone for that matter. I always keep an open mind in achieving and in being a student of life on a whole. My overall learning and progression in life as nothing to do with numbers calculated by someone else. After all, it’s all in the game of life and how it is played than by what is attached to it by other’s perception. Only each individual themselves, will know what they need to learn next; and at what level they truly are at their rate of progression. However, I do believe that some people are gifted with a great understanding of mathematics, and that they should contribute to society in some way for the good with their gifts.
Thanks for interesting blog.

This is very interesting, though I don’t think that the “smartest people” list is all that accurate. What is really shows is “pretty smart famous people.” A list of Mensans might give a better list, but it would still not account for all those people with genius IQs who just never took a test to prove it. I mean, I wouldn’t be less smart if I had never taken a professional IQ test.
I do not believe in the higher values quoted. 100 IQ is supposed to be average. 110 would be a 1-10 individual. 120 a one in a hundred. 200? Gotta call BS. 10^9? This would correspond to the absolutely smartest person on earth, probably an unknowable proposition. The idea that intelligence is knowable to three figures of precision is even more dubious. The idea that intelligence is a solitary parameter, ridiculous!
Philip Emeagwali is more of a myth than genius. There are too many lies spread about him. Luckily the wikipedia updaters keep the links to the sites pointing out the inaccuracies about him, including the fact that there are no apparent actual patents under his name, though it is claimed he has 30+.
I usually score higher on other IQ tests. Mostly in the 120 range. I got 112 on this one. That is still considered as “Superior Intelligence”. I like that title. Much better than average.
Great list. Fascinating. Though I must say it seems that the IQ of individuals in the past is a matter of total guesswork.
Don — Take a look at the graph at the top of his post. It shows that 50% of the population falls between 90 and 110. So a 110 IQ is at the 75th percentile (that is, 25% of the population have an IQ of 110 or higher), not the 90th.
how were the estimated IQs of folks from the past arrived at? I’d really be interested in applying the algorithm to someone like Thomas Paine. Couldn’t find anything online about his IQ.
