++Addition++After reading multiple comments critiquing the post for the same thing, it’s clear that I did a poor job of explaining what the table purports to show. It’s not supposed to be an exact measure of IQ by profession by any means, as it is based entirely on average annual income figures. In other words, it’s an income table with the values converted to IQ scores (and thus, as silly girl points out, it’s a bit of a mislabeling on my part, although that is the point–to get an instinctive feel for how related IQ and income are at the career level).

As Saint Louis notes, physicists and astronomers are surely understated, while physicians and surgeons are overstated. Some of that, again, is a result of the prerequisite training required to enter those medical fields, and some is a result of the full workload and working conditions doctors and surgeons face relative to that of astronomers or chemical engineers.

Career Cast recently published a list ranking 200 major occupations from best to worst, as measured by five criteria. One of those is income, displayed as the median earnings in a field plus a small premium based on income growth potential.

While income is positively correlated with IQ, it’s obviously not perfectly so. Nonetheless, the following table estimates average IQ scores by occupation solely on the basis of the Career Cast mid-level income figures. The median salary (of a paralegal assistant) is taken to correspond to an IQ of 100. One standard deviation is assumed to be 15 IQ points:

With the exception of an astronomical score for surgeons and one in the stratosphere for physicians, it’s pretty predictable. And when I say that, I mean the scores are about what you’d predict to see if someone showed you a list of IQ by occupation without informing you of how the scores were determined. Pay is generally commensurate with an occupation’s cognitive demands, which is why the list has a great deal of face validity.

The apparent misrepresentations are the ones that irritate me the most, perhaps exposing me for an IQ meritocrat (or maybe its a visceral disdain for high IQ vampires who use their intelligence to parasitically suck the blood of their productive neighbors). I’m skeptical that nuclear engineers are, on average, ‘less intelligent’ than attorneys or that software engineers tend to have lower IQs than physicians.

Some of this is a result of credentialism, with medical school requirements being more difficult to fulfill than various certification requirements for software developers, even though being a successful software developer requires a higher IQ than being a doctor does. Some of it the result of the personal interaction premium, where, relative to the objective value people create, those who do so largely through direct communication with other people enjoy greater remuneration for their efforts (this trend is generally beneficial for women at the expense of men).

Of course, some of this ‘dissonance’ is due to crucial factors other than intelligence. Corporate executives need high executive function and strong leadership capabilities, while aerospace engineers, despite presumably having higher average IQs, do not have nearly as demanding non-IQ requirements for success.

  1. I don't see "Epigone" on the list anywhere but I guess that's what your day job is for.

    This sounds kind of similar to some of the stuff Half Sigma has written, and I believe that it is mostly true, but money is only one small piece of the puzzle. A higher IQ person who doesn't earn his or her potential still hopefully is able to do something they like and lead an interesting life. This topic is on my mind since a friend of mine expressed concern he's in a dead end clerical job at age 29.

    Off topic, but my captcha for this comment was "phapre," which is funny if you say it out loud.

    Speaking as a doctor, I think the estimates of physician's (161) and surgeon's IQ's(234) are terribly flawed. In my experience most doctors probably fall in the range of 115 to 140. 115 is probably adequate for the job, and given that minimum, their success is correlated with work ethic and drive, not IQ. Additionally, the list underestimates numerous occupations. For example, mathematician: 119. ?! I would think 140 or so, based on the graduate school math types I've been acquainted with. I believe many of the engineering professions are also underestimated, with 115 probably the minimum necessary IQ in engineering, the average should be higher. And many of the blue collar jobs listed at 100 and below require significant analytical and quantitative aptitude, probably at least 110 IQ. Corporate executive: 147? Most CEO types are persuasive communicators and leaders with IQ's around 115-125 give or take. An IQ above 140 is probably a barrier to success in most fields.
    Finally, technical writer, 106? Woah. Obviously income does not correlate perfectly with IQ. The outliers do stick out.

    • Replies: @David

    I agree with the Dr. Who ever heard of iq in 200's.

    Also in CA MD's Licensed by the State are surges when you check CA State Web Page, so it seems all Doctors are surgens.

    , @Unknown

    Would anyone want just an adequate doctor or surgeon, or would they hope to be getting the best?

    , @Anonymous

    Donald trump must have a massive IQ...

  3. Overrated by this measurment:

    Surgeon (234.1): obviously, since by definition the number of people in the world with an IQ 10 standard deviations above the mean is between zero and one

    Physician (161.1): again, obvious; there are certainly some at that level, but it's not the median

    Corporate exec (148.0): probably more like 125-130 with great people skills

    Financial planner (122.8): similar to corporate execs, but minus about 10-12 IQ points


    Judge (127.9): Either judges are underrated or attorneys are overrated. The average judge is quite a bit smarter than the average attorney (certainly more then 0.1 IQ points). I'd drop about 3 points off from attorneys and add about 3 to judges. Then again, if this is including all sorts of local magistrates, etc., then maybe it is accurate.

    Physicist (124.9): I would think this is about the minimum to enter the field, not the median. Then again, there could be a lot of them out there with lower verbal IQs dragging down their scores.

    Astonomer (124.5), Nuclear Engineer (121.1), Aerospace Engineer (120.2): see Physicist

    What might be going on with the three previous ones is that many of them are likely government workers. They probably enjoy amazing benefits and pension packages. If benefits were included in the calculation, you'd probably see higher numbers for them.

    Philosopher (105.9): this is probably about 30 points too low; this is a job our society clearly doesn't value

    One that caught my attention:

    Clergy (98.4): this must include evangelical ministers, mega-church pastors, and black preachers; if you only measured Catholic priests and those from the mainline protestant groups, I bet it would be more like 110; Catholic and Episcopal bishops are probably more like 125

  4. If you remove medical and business oriented professions and readjust accordingly the results would probably be closer to what they really are.

  5. Regarding what I wrote about clergy: the median IQs I posited are what I suspect they actually are, not what their median salaries would suggest.

    Indeed, I wouldn't be surprised to see a slight inverse relationship between remuneration and IQ among clergy. After all, a lot very bright Catholic priests take vows of poverty. Meanwhile, a lot of intellectually middling (but with high charisma) evangelicals and mega-church pastors probably rake in the dough.

  6. dishwasher 87? that seems high

    As for clergy, they have pretty high verbal GRE scores on average, so they can't be too stupid. Now, of course that only applies to those denominations that require GRE scores for applicants to the M.Div. programs, and those GRE numbers also include students who don't have M.Div as their degree objective. Do Rabbis have to take the GRE to go to seminary?

    This ranking method is interesting a la IQ and the Wealth of Nations and yeah, there are other factors in play, which is, why it really is somewhat mislabeled. It is more like an IQ/ambition vs. income index. If IQ and drive were somehow combined into a single score, then it would make more sense.

  7. Computer Programmer is way too low – this should be in the 120-160 range, with a median IQ of about 130.

    I agree with Anonymous's (#2) estimates for physician, 114-140, as I'm married to one and know many socially, and none are intellectuals, but all hard working, with a median IQ of about 120.

  8. Income is frequenty a poor proxy for IQ. Wages are determined for economic reasons only some of which are related to ability. Clergy and ag scientists are example.

    New York City is awash with high IQ taxi drivers (many with PhDs) who do to various reasons can't practice their chosen fields, and few of the best performers on Broadway have escaped stints as waiters.

    There is some relationship between the two, but this is really nothing more than an income chart with misleading units.

  9. Charles Murray on Turkheimer's paper about heritability of IQ

  10. Thanks.

    How well do these career labels match up to the ones used in the GSS? If they match well enough, then you could correlate pay to scores on the GSS vocabulary test. It would be fun to look at outliers, such as "author."

  11. Steve,

    I'm going to give it a shot this weekend. There are not nearly 200 job categories with sample sizes large enough for a comparison in the GSS, though–we're probably looking at 30 or so.

  12. "Surgeon (234.1)": good God, someone's dug up Isaac Newton and taught him to be a sawbones.

  14. This is a plainly ridiculous post.

  15. So I suppose that professional athletes routinely have 300+ IQ? Hehe…

    Interesting list, though.

  16. It would be interesting to recalculate assuming a log-normal distribution of income. I suspect that medical folks will still be over-represented, but not nearly so badly. A while back I looked at U.S. income statistics, and it appeared that the standard deviation for a log-normal distribution was about 0.375.

  17. Door-to-door salesman: 72.9

    I was almost sucked into working a job like that, but I did some research on the Internet first and saved myself the trouble (they do business with different names, and actually charge you money to sign up, knowing that 90% of people are gonna quit when they find out what it is).

  18. Anthony,

    I haven't played around much with the LONGNORMDIST function in excel, but that would reduce the absurdly high values for things like surgeon (and professional athlete, too, if that was a broad job category actually reported on!)

  19. AE:

    Could you post a second chart next to this one with the actual IQs of those professions? I think it could help the readers see the difference between the actual IQ of the profession and what society value's in terms of IQ.

  20. Never knew basketball players were geniuses.

  21. So now we know, doctors and dentists are overpaid relative to their intelligence.

    I guess in their defence, medical workers would say they are paid more than other workers because they work harder and tend to be under higher stress levels than most educated workers.

    Relative to intelligence, journalism would have to be one of the worst paying jobs.

    Writing quickly and accurately to tight deadlines about topics which you may not know much about requires a far amount of intelligence and hard work, yet wages are often worse than in the semi-skilled trades.

    Oh my! Now surgeons aren't only gods, but they have a higher IQ than God himself???? You've GOT to be kidding me. Physicians, Surgeons, and Psychiatrists are all physicians. And IQ varies within the group, but from personal and professional experience with all types of physicians, the average is much lower. Personality determines specialty more than anything…

  23. What BS, especially for the physicians and surgeons. This may represent what they think about themselves, but it surely can have no basis in fact. My hunch is, average physician 125, average surgeon, perhaps 130. They are not the geniuses everyone thinks they are.

    I've been a computer programmer for 15 years now. I think I've worked with programmers with IQs easily over 130 as well as those with IQs easily under 100. How do I explain this wide range? I honestly think that the IQs of those that hire programmers seem to always be lower than the programmers they hire. My conclusion is that there are a lot of managers dumber than the people they hire. The "EQ", general aggressiveness, and a propensity for bullshit seem to be a requirement for climbing the ladder, at least in I.T. I'm sure this sounds like a broken record, but it's true. What's my point? Well, I'd like to submit to the readers that the computer engineer job title might hold the largest range of IQ scores.

  25. Where did you get this information from? It is total BS. The highest IQ of any living person today is of Marilyn vos Savant, who has an IQ of 228. Also, I highly doubt the the average waiter or dishwasher has an IQ just slightly above legally retarded.

    This doesn't even pass the laugh test. There are far too many career paths that result in low earnings and salaries. There are also plenty of smart people with low IQs, as it isn't a measure of how bright someone is, but their ability to reason and problem solving. What you are left with is something that is more correlated to education level, than IQ.

    In my particular field and aiming to hire people with above average problem solving skills, and slightly below median income levels, IQ is an important measure. It trumps education levels and knowledge. We find great success in hiring people as a result of pre-employment testing and above average IQ scores. Life chances brought them to our door, and perhaps they didn't have a secondary education or pursued a career path without much opportunity. By the measure here, we would need to pay prospective employees nearly twice the salaries we offer and it's long been dismissed that there is any meaningful correlation between IQ and income.

  27. An actual quantifiable study was done on IQ level of M.Ds. The IQs and demographics were available for an eastern city. All school children had to take IQ tests. Many of those children ended up as M.Ds. The Intelligence Quotients averaged out about 105. Decades later, a few years ago, another study was accomplished. The researcher discovered that many doctors had family members that had already been through the process and had drilled the aspiring medical students and walked them through everything before they were tested or observed. They squeaked by. That seems to explain all the dumb doctors so many of us have run into.

  28. Decades ago the IQs of an eastern city's students were collected, the IQs of students that went on to be doctors averaged out to 105. Recently research was carried out and it was discovered that many medical students had relatives that were already doctors and had been drilled and walked through everything before being tested or observed, thereby squeaking by and are now "practicing" on the rest of us.

    Considering that the highest IQ ever recorded is a 212 and the most intelligent man in America scored a 200 – both of which are >= 50 points higher than Einstein, I'm going to confidently state that this is wrong. Also, someone with an IQ of 160 is statistically 1 in a million, which means they have 7000 peers on the planet – and 30,000 students graduate from medical school in America each year – so yeah, this is more than a little off.

    There is no profession that would be accurately represented by a median IQ of 234. Few in the history of mankind could legitimately have an estimated IQ of 200, such as Goethe, Newton, da Vinci, or Einstein. I've known plenty of neurosurgeons (I'm a neuropsychologist myself), and none of them are even remotely close to the intellect of someone like Goethe.

    computer programmers/engineers are underestimated. most people who advance in that branche usually stop being programmers later on, moving up the ladder. second thing is that most people work for western countries while living in poorer countries (outsourcing workforce and freelance programmers) and they generally have very high salaries for conditions in countries where they live.

    I don't know what septic tank they got this load from but according to this BS every doctor is a genius. Frankly, I've met to many doctors that can't even understand simple Physics. Yet alone, begin to understand the human condition. Income is vastly more dependent on oportunity than I.Q.

  36. I think you've labeled a column IQ that isn't IQ. It's like a village idiot wrote this for other village idiots.

    I can't believe anybody buys into this crap. Someone literally just made these numbers up.

    When it comes to standardized testing, people who pursue general surgery residencies do approximately equal to those who pursue general medicine residencies (e.g . surgeon vs physician). This is a fact per the National Board of Medical Examiners and the American Association of Medical Colleges. Then, to put them at an off-the-charts IQ range just makes this so far beyond laughable it's shocking that some people are taking this seriously. o_0

    Speaking as an Orthopedic Surgeon, I was greatly surprised that on your list I have a higher IQ than the best chest player currently alive and higher than Bill Gates and Steve Jobs. If my welath was proportionate to this difference of IQ between Bill Gates and I, I wouldn't need to be a surgeon anymore.

    A little bit overrated IMO, where did you get these average numbers?

  40. Anonymous • Disclaimer says:

    These are complete fallacy. I've seen legitimate IQ compilations, and physicians and surgeons typically top the list, but we're talking 90% of t hem being between 120-140. And, there is no huge difference between a physician and a surgeon. An average internal medicine candidate scores equivalently on all examinations to an average general surgeon candidate. And, I hate to tell you all, but surgery does involve thinking, but it's less intellectually challenging than a large host of occupations.

My mother's side of the family all had genius IQs and one uncle's was 176 (they had idiot savant characteristics in some cases), and I have a genius IQ, too, and I have to tell you I have never run into a surgeon or a CEO of that caliber. This is just BS.

    I haven't run into too many doctors that would even say qualify as genius level, most have college-level IQs and even less. Nothing is wrong with that, but this is absolute baloney. This is just spreading a lot of disinfo. Obviously this person doesn't qualify high on the scale either.

    Yes, it's bemusing (but also frustrating) to see that charge repeated over and over again, as though I'm arguing that this legitimately and rigorously measures IQ, when, if there is a point–and it's more an FYI/thought-provoking post than anything else–it's that income is determined by a lot more than just IQ.

    160 or so (if im not mistaken) is approaching genius status. Physicians are around 130 which is very high. When you hear people talk they exaggerate numbers and don't understand what a true IQ is. Bobby Fischer was like 200 or 212 or something. Surgeons are smart…they aren't that smart. Many of these IQ's are due to dedicated learning. Mankind as a whole doesn't wake up one morning with an IQ of 150. It doesn't work like that. BTW, I know some people with legitimate high IQ's and they are dumber than a box of rocks. IQ's are only relavent….if they are relavent. What test decides how smart someone is? A doctor with an IQ of 135 who claims carbohydrates are the cause for obesity is obviously not intelligent enough to help a pt. lose body fat. But his IQ is 135…so what?

    Intelligence is multifaceted, often unbalanced, and it is the specific cognitive talent that plays a role in professional success.

    My IQ consistently scores between 130 and 135 on standardized intelligence tests. However, while my GRE verbal and analytical scores are both somewhere above the 90th percentile, my math scores fall just a little better than average at around the 52nd percentile. Suffice it to say, quantitative reasoning has always been my Achilles heel.

    You can derive from this that I might exceed in a variety of professions within, say, the medical field (my field) but I would make a lousy engineer or mathematician despite what the result of an IQ test might indicate to some. It is also my experience that I have a verbal reasoning ability that seems to exceed what might be expected from my official IQ number (which is derived from a non-verbal reasoning heavy test).

    There are other factors influencing income besides intelligence, to the point of making something like this worth little more than a party trick. People in the military or government service, for example, tend to be paid less than their private sector counterparts for well educated positions but better for more menial positions. My father had a very high IQ but never made a lot of money as a career Army officer.

    In medicine, specialists make significantly more than primary care physicians even though they aren't significantly more intelligent. I talked once with a surgeon who was a chief of surgery at a hospital. He said his IQ was 115 and he made $600K a year.

    Whites earn more than blacks, men earn more than women, tall men earn more than short men. People get paid more to work in dangerous or unpleasant conditions.

    This post is so far off base, it's ridiculous. First off, this post does not even begin to explain what and IQ is a measurement of (I know you already "know the answer and are thinking, "Intelligence, duh! Stupid." But there's more to it.).

    An IQ test is a STANDARDIZED test. What this means is that an IQ doesn't measure one's intelligence, per say. Rather it measures how one performs intellectually compared to one's peers. One thing, and maybe the only thing, this post got right was the standard deviation (SD), which is 15 points (usually, though it depends on the test you are taking). Anyone that scores 2 SDs (meaning an IQ score of 130, at least with regard to the WAIS-IV IQ test) above the mean (IQ = 100) is considered slightly gifted, or a genius (or at least what MENSA will accept and acknowledge as genius).

    There are three main IQ tests out there: the Stanford-Binet (mean IQ = 100, SD = 16), the WAIS-IV (mean IQ = 100, SD = 15), and the one offered by MENSA (not sure what the mean is, I would guess 100, and I have no idea what the SD is). To be clear MENSA will accept an IQ of 132 (measured by the Stanford-Binet) or an IQ of 130 (as measured by the WAIS-IV) as genius. Again, I'm not sure what score they require on their tests to qualify as a member.

    Here's the other key point to be made when speaking of IQ tests and measurements: the actual test has no units. It DOES NOT ACTUALLY MEASURE ANYTHING. HENCE, the reason the tests are standardized. What the test does measure is, as said before, your intellectual performance compared that of your peers (i.e. men and women of the same age as you). This tells you how you compare the rest of the population.

    The reason that a test score that is 2 or more SDs from the mean is accepted as genius is because this means that the individual out performed 98% of the population. In other words, only 2% of their peers could outperform them intellectually. Meaning that if you are a genius, there is a 98% chance you are the smartest person in whatever room you occupy. Conversely, there is only a 2% that any random Joe Shmo will be smarter than someone with an IQ of 130. How's this relate to the post you ask? Good question, I'm glad you asked! 😉

    Physicists, Software Engineers, Chemists, Biologists, Philosophers, Doctors, Designers, Inventors, and so on, are certainly very intelligent people. But just because they are intelligent does not mean that they are a true intellectual genius (i.e. that they have an IQ of 130 or greater). Even if they do happen do be a genius, or expert, in their respective field. Only 2%, read that again, yes 2%, of the ENTIRE POPULATION, of the world, has an IQ of 130 or greater. With 7 billion people on this planet, that leaves only 140 million (2% of 7 billion) people on the planet that have an IQ of 130 or higher.

    With all the occupations listed on here with an IQ of 130 or higher, I'd say that the total number (I'm talking world wide here) of people that occupy those occupations (does that sound as weird to you as it does to me?) is over 140 million. Based on just that you can throw this silly chart out.

    There's a lot more to this sorely flawed an fallacious article than I have pointed out, but I think this horse has been beaten to death more than enough times already. Though I did enjoy the post for the laughs. I know Epigone said this post was more about correlating IQ with occupational income, but I felt the need to point out some of the parameters surrounding IQ scores and measurements. Perhaps a follow up edit or post correcting and elaborating (more) on this chart would be helpful to readers.

    IQ and how much money one makes have no correlation to each other.

    As a matter of fact most geniuses (IQ over 160) are either unemployed, destitute or own their own successful businesses. Hiring managers of large corporations usually do not hire over-qualified geniuses.

    How much money one makes is purely tied to supply and demand. If there is a product, skill, service or industry that is low in supply and high in demand it will become more valuable and thus more profitable or receive higher wage payouts.

    If everyone was given an opportunity to become a surgeon and everyone became a successful board-certified surgeon then the supply would exceed the demand and board-certified surgeons would only make minimum wage. Does this mean the surgeon’s has a low IQ because he makes minimum wage? No!

    IQ and how much money one makes have nothing to do with each other. How much money an individual, corporation or industry makes is purely linked to economics, primarily supply & demand.

    All of the listed professions up above will become replaced by Artificial Intelligence robotics technology within the next decade and the price of products and services in ALL industries will also come down by 50 to 100 times. Everyone from a surgeon to a lawyer to a dishwasher will be worth less-than minimum wage when AI replaces human labor. Does this mean the IQ of these professionals has dropped? No! It simply means that AI can perfectly carry out complex jobs requiring high intelligence, abstract reasoning & creativity as well as unskilled menial jobs around the clock, 24/7 at 50 to 100 times lower costs than any human can regardless of skills, education or IQ.

    Even the most advanced field will become high in supply and low in demand when AI supersedes human labor making all human professions less-then minimum wage in value. Again, how much money one makes is directly linked to economics, i.e. supply & demand, not IQ.

    In actuality the smartest human professions are: Physicist, Mechanical Engineer, Electrical Engineer, Aerospace Engineer, Automotive Engineer, Software Engineer, Nuclear Engineer, Electronics Technician, Avionics Technician, Computer Scientist, Materials Scientist, Aircraft Mechanic & Automotive Mechanic. All the other professions out there could not even exist without these technical professionals. That is because Physicists, Engineers, Mechanics & Technicians hold most if not all technology patents allowing ALL of the other professions to exist.

    There is no correlation between IQ and how much money one makes. As a matter of fact 95% of all billionaires are high school drop-outs or college drop-outs that never held a steady job. All of whom learned at an early age that making money is all about going into business for one’s self and developing or investing in low supply products/services in high demand markets.

  85. I am astonished that anyone would present, to the public, an Intelligence/Income chart based on income (and potential for greater income)! As one might expect, the incomes at the top are overwhelmingly in three fields: Medical, State and Unionized. I will concede the Medical (partly because I must trust my doctor for my life, so I believe implicitly that he's really smart!) The State pays top dollar for its workers. My wife is a Master Teacher, but works in a private school – $24,000 a year for the same job for which a veteran teacher commands $80-90,000 annually. That's State and Union working together, not native intelligence, for the high wage. I myself tested 145 for IQ (my first test was 103, but I improved on each one, learning better how to take the test). As a minister, my salaries were just about where you put them – in the middle (perhaps a cynic would say my career choice was IQ 70, and thus it evens out?). I cannot imagine that my college prof's had anything on high school teachers – one needs far more education and native ablity to teach high school than college, and more to teach elementary than high school.

  86. …a postscript: Examining another chart (Henmon-Nelson), I observe that 25% of the janitors (lowest ranked of all) outscored 25% of the college professors. The view from the standpoint of the anomalies does indeed look pretty close to reality.

    I think there are quite lot of misunderstandings in this list. As a medical student I agree an average doctor having an IQ of 110-140 as reasonable but giving such a immense value of 234 which excels the highest value of IQ a person has in this world. IQ is a big scope which I'm not gonna cover in this comment, although if you look at this list it's obvious that the author has considered only the values of memory related IQ while neglecting most of the logical part. Also author has purposely prioritized on medical related jobs as firsts in his list which is a big second mistake. If we take the statistical data about high IQ prodigies in the world and which profession they've moved for later in their life, highest score goes to Mathematics and engineering. So it's clear since the author has put them into a much shallow score, most part of this list is a mess.
    On the other hand the truth is doctors don't have a big logical knowledge as math oriented scopes because most of the time (over 70% in our medical college life)we only have to deal with medical books, not with new things or logical juggles. So as the bottom line I can say and you'll also agree that putting medical career as the first place while throwing away such high IQ required scopes like Physicists, Engineers and mathematicians is a big mess after all.

    This data is really stretching having any validity. While there is a positive correlation between annual income and IQ, it all but completely breaks down when you look at it from the perspective of individual occupations, especially those toward the high end of the spectrum.

    This is due to the way we value some occupations relative to others as a society, and pay scales do not fall along a standard bell curve the way IQ does.

    The average IQ of the "smartest" profession is likely not over 130 or so; it certainly isn't 160 or 230. Additionally, the average IQ of surgeons, CEOs, and physicians is certainly not higher than the average IQ of most types of engineers, scientists, and professors.

  93. @Anonymous
    Speaking as a doctor, I think the estimates of physician's (161) and surgeon's IQ's(234) are terribly flawed. In my experience most doctors probably fall in the range of 115 to 140. 115 is probably adequate for the job, and given that minimum, their success is correlated with work ethic and drive, not IQ. Additionally, the list underestimates numerous occupations. For example, mathematician: 119. ?! I would think 140 or so, based on the graduate school math types I've been acquainted with. I believe many of the engineering professions are also underestimated, with 115 probably the minimum necessary IQ in engineering, the average should be higher. And many of the blue collar jobs listed at 100 and below require significant analytical and quantitative aptitude, probably at least 110 IQ. Corporate executive: 147? Most CEO types are persuasive communicators and leaders with IQ's around 115-125 give or take. An IQ above 140 is probably a barrier to success in most fields.
    Finally, technical writer, 106? Woah. Obviously income does not correlate perfectly with IQ. The outliers do stick out.

    For the IQ test of your choice whether its Wais(STd 15), Stanford-Binet(STD 16) or Cattell(STD-24) put in 234 and then click calculate. Now it doesn't matter which one of the 3 you choose because in each of the 3 cases you get the rarity(at the botto, where it says 1/x) you get infinity. In other words ITS IMPOSSIBLE FOR ANYONE TO GET AN IQ OF 234. So suffice to say stating that Surgeons(or any person) have an IQ of 234 is beyond absurd.

    Also the idea that Physicians on average have an IQ of 161 is also absurd.

    I also very much doubt that Mathematicians on average only have an IQ of 119 and that their IQs would be on average less than Corporate executives(I also doubt on average CEOs have anywhere near an Average IQ of 148), dentists, Orthodontist, Financial planner, Astronomer, Physician, Commercial airline pilot or even a surgeon.

    "The highest IQ of any living person today is of Marilyn vos Savant, who has an IQ of 228. "

    That is a myth. Savant never scored that high. For more detail read the following

    "Alan S. Kaufman, a psychology professor and author of IQ tests, writes in IQ Testing 101 that "Miss Savant was given an old version of the Stanford-Binet (Terman & Merrill 1937), which did, indeed, use the antiquated formula of MA/CA × 100. But in the test manual's norms, the Binet does not permit IQs to rise above 170 at any age, child or adult. And the authors of the old Binet stated: 'Beyond fifteen the mental ages are entirely artificial and are to be thought of as simply numerical scores.' (Terman & Merrill 1937). …the psychologist who came up with an IQ of 228 committed an extrapolation of a misconception, thereby violating almost every rule imaginable concerning the meaning of IQs."[11] Savant has commented on reports mentioning varying IQ scores she was said to have obtained.[12]"

    Sorry, I'm calling BS. as a British Mechanical Engineer I'd say almost all my colleagues are way, way smarter than "112".
    My IQ is over 150, as tested several times, and I'd struggle to tell the difference between a person with an IQ of 112 and person with an iq of 90…..

    Last time IQ was tested in college professors they scored an average of 116, doctors 121.

    Internal polls of Mensa indicate that members of Mensa have a median income of 10% higher than the general population.

    I suspect that "IQ" plays a smaller role in income than the average person assumes.

    While I wish this chart was accurate even for my 'mere' 140-150 range, in my experience I know to many Mensans that work at Home Depot to believe it. ---good day

    A historian needs a much higher IQ than average, tell David Starkey or Dan Jones that they only need an IQ of 105; David Starkey must have an IQ of at least 145 and probably a lot higher. Also, the term "nurse" covers a vast area, and if you have ever had an endoscopy you will know that the theatre nurse is who primarily deals with you the patient, she is to an extent in charge of the surgeon too, and probably has an IQ of at least 130 to be able to do that job. She also has to re-assure the patient and explain what you have to do. I also agree with the post above me that a lot of engineers have to be extremely intelligent, in the region of 150 as he says. Teachers come in all ranges of intelligence, from the nasty little schoolmarms who would struggle to score 95, to teachers who really care that everyone understands their subject and even try to care about those who are learning much faster than the rest of the class, we had a teacher like that and he probably scored around 135, lovely guy, very patient, very deep understanding of his subject.

    Speaking as a doctor, I think the estimates of physician's (161) and surgeon's IQ's(234) are terribly flawed. In my experience most doctors probably fall in the range of 115 to 140. 115 is probably adequate for the job, and given that minimum, their success is correlated with work ethic and drive, not IQ. Additionally, the list underestimates numerous occupations. For example, mathematician: 119. ?! I would think 140 or so, based on the graduate school math types I've been acquainted with. I believe many of the engineering professions are also underestimated, with 115 probably the minimum necessary IQ in engineering, the average should be higher. And many of the blue collar jobs listed at 100 and below require significant analytical and quantitative aptitude, probably at least 110 IQ. Corporate executive: 147? Most CEO types are persuasive communicators and leaders with IQ's around 115-125 give or take. An IQ above 140 is probably a barrier to success in most fields.
    Finally, technical writer, 106? Woah. Obviously income does not correlate perfectly with IQ. The outliers do stick out.

    Would anyone want just an adequate doctor or surgeon, or would they hope to be getting the best?

    I have an IQ of 127, and have been a ( 88 IQ ) cashier all my life.

    What does this say about these silly little results and correlation between income and intelligence ?

    Something that I think certainly skews the graph is that a lot of the occupations on the lower end of the IQ scale are jobs performed by younger people, dishwasher and such, breaking into the workforce. Peak brain performance caps out at about, what, 24 I believe? Further, the working poor tend to have lower IQ's because of their economic status – poor diets, long hours that consume free time for more intellectually stimulating activity, etc. So, I think charts like these are kind of foolish.

    The data are fictitious…absurdly so. In my brief search for information on this topic this is the second time I have seen the table.

    The statistics do not make sense and were created by someone ignorant of statistics and psychometrics. It is not even plausible lie. There are not enough people in the world in the upper IQ ranges to fill those professions. Others have pointed this out. IQ's are measured with a mean set at 100 and typical standard deviation of 15 or 16. That people post this and comment this information a bit of a shame (ah I am commenting, what a shame). Unless the evil genius was to get responses to the misinformation.

    For those that comment: Do the research, take a class, read a book and ignore how you feel about it. People talking about who they know, who they are, or what their IQ is has no bearing on the issue. Murry and Hernstein wrote a controversial book in the 1990s that deals with this and other issues. Read the book to understand the methods and patterns and then decide.

    Why would anyone bother to make a table of nonsense is the more interesting question. Did a surgeon make it? A physician that is a surgeon?

    How do you estimate IQ from income? There is a correlation but I cannot imagine a valid method to create the estimates here.

    Wow, I just took 10 minutes reading this and writing comments on it. That must have been the purpose for it, suck me in from search for research on the topic I was doing.
