IQ 200 or above impossible

IQ 200 (rarity)
A Wolfram Alpha return result for “IQ 200” (Ѻ) overlaid with five of the highest mean Cox-Buzan IQs, which shows that there is an exact correction between the percentile IQ rarity method, which shows that of the approximate 80 billion people, come and gone, since “modern” humans formed about 40,000 to 150,000-thousand years ago, only “one” could have possibly had, theoretically, an IQ of 200, and that IQs above 200, e.g. the Cox-Buzan mean estimate of Goethe’s IQ as 213 (Ѻ) is impossible being that this has a rarity of about one in 40 trillion people. This is an example of a mathematical calculation not matching up with reality.
In genius studies, IQ 200 or above impossible refers to the assertion, made by some, that an IQ of 200 or above, e.g. IQ:200+, IQ:225+, etc., is realistically, physically, and or theoretically impossible, per reasons of statistical improbability, so-called "fat tail" distribution arguments, among others.

Overview
In 1917, Lewis Terman, the modern IQ scale inventor, used his formula to calculate, as a test case, an IQ of 200 for Francis Galton (see: IQ miscalculation) based on his intellectual ability as a youth, between ages 3 and 8. [1]

In 1926, Catherine Cox, Terman's graduate student, in her 8,000-page based treatise Early Mental Traits of 300 Geniuses, along with her team of psychologists at Stanford, calculated the IQs of the top 300 geniuses, who existed between 1450 and 1850, based on intellectual accomplishments, per decade of existence, and therein came to rank Goethe as the #1 genius in this grouping:

“One rater (M) has scored on the basis of the record of Goethe’s youth an IQ of 225. Goethe’s true IQ may in the history of mankind have been equaled in a few instances; one may well wonder whether it has ever been exceeded?”

In 1946, Abraham Sperling, in his “A Story of Genius”, was reporting the IQ of William Sidis as being in the 250 to 300 range: [2]

“There was no lessening of William Sidis' mental acuity. Helena Sidis told me that a few years before his death, her brother Bill took an intelligence test with a psychologist. His score was the very highest that had ever been obtained. In terms of IQ, the psychologist related that the figure would be between 250 and 300.”

In 1981, Agustin De Mello, amid his extreme forced prodigy experiment on his son Adragon De Mello, estimated the age 5 ratio IQ of his son to be in the IQ of 400 range:

“Agustin tested AD's intelligence when the boy turned five. He calculated an IQ of 400, meaning AD might rank as the greatest intellect in history.”

In 1988, De Mello, aged 11 years 8 months, set a world record by graduating from college with a BA in mathematics from the University of California, Santa Cruz.

In 1988, Kevin and Cassidy Kearney, amid the peculiar child rearing methods of their son Michael Kearney, estimated his age 4 ratio IQ to be 325:

“At age four, two psychologists and one sociologist gave Michael Kearney the Stanford-Binet IQ test (L-M version), a test designed for highly-gifted children age six and above. Michael scored 168, the ceiling of the test. Michael’s parents, Kevin and Cassidy, in their own words, “discovered in the library that the Stanford-Binet L-M version test gives a mental age which can be ratioed with chronological age for a true IQ … Kevin and I did the math and came up with Michael’s IQ at 325.”

Kearney would go on to beat De Mello’s record, by getting a BS in anthropology from the University of South Alabama at age 10.
Fool's IQ


In 1996, Marilyn Savant, college dropout who as an adult began to engage the world of making and taking IQ tests, faked an IQ of 228, via falsified age records of a Stanford-Binet test she took at age 11, which she got in the Guinness Book of World Records, which read as follows:

“The highest childhood score has been achieved by Marilyn Mach vos Savant who as a 10-year-old achieved a ceiling score for 23-year-olds thus giving her an IQ of 228.”

This Savant-citation remained in Guinness Book, before they removed the category, in 1996, per reason of "verifiability". Into the 2000s, Savant was still be parlayed around as the "smartest person ever", without, however, having produced anything of intellectual note.

Hence, in this general "obervationalist" point of view, sorting through IQ:200 range estimates is like separating the pyrite (FeS2), aka fool's gold, from the gold (Au): many people are fooled by pyrite, but only the gold is of any value.

Thims
See main: HCT IQ:200-range prodigies
Of note, Libb Thims was goaded into "IQ ranking" (and re-ranking) when on 17 Feb 2010, the "IQ of 400" citation for Adragon De Mello was found, and subsequently added (see: version 214) into Thims growing circa 2006 to present IQ:200+ collection; after which, the ranking of geniuses by purely "cited" IQs (below right) became mentally incongruous, no longer visually pleasant to look at, i.e. a nonsense ranking:
Thims IQ 200+ collection (2007-1010)
after which Thims was "forced" into doing his owing re-rankings of ceiling range IQs, which resulted firstly the genius IQs (24 Oct 2011) page, which then transformed eventually into the more-cogent five-part top 500 geniuses (Jan 2014) set of pages, ranked by real IQ (or true IQ), i.e. IQs that match up with reality.

The following shows the actual dates when Thims began to discover these various 200-range IQ during his research (see: footnote 2.5); IQs shown cited by other (not Thims):

The above infobox shows, seemingly, that if one is a coming of age prodigy in the IQ:200± range intellect, one's mind will "naturally" gravito-electromagnitate towards a chemical thermodynamics model of the existence of things, in one way or another, being that the first law and second law are what define "nature" of things, in modern terms. The 200 range genius will use certain "key terms" that are common to other 200 range geniuses; such genius will put these ideas to print and or discuss them with someone who puts these ideas to print. These ideas will be discovered by other 200-range geniuses (similar to the "blue sky problem" common to pre 20th century IQ 200 range geniuses). Hence, the myth of the "anonymous 200-range genius", who supposedly works in isolation from the connected community, seems to be myth.

IQs: 500+ | 1000+
Over note, in the 2011 film Limitless the fictional genius nootropic drug imbibed character of Eddie Morra claimed to have a 4 digit IQ and has been characterized (Ѻ) by some as a “21st century Faust.” Since then, there has been a certain amount of discussion as to "what would it be like" to have an IQ of 500 or 1,000. [3] These types of speculations, however, are without merit, and lacking a true conceptual basis of what the IQ scale in the so-called ceiling range or "fat tail" end seems to entail, namely that the closer one gets to the 200 range, plus or minus, the harder it is to maintain, retrospectively speaking, e.g. Aristotle seems to have held his place at the 195 position, in 2,300+ year retrospect, Da Vinci at the 200 position, in 500+ year retrospect, and Goethe in the 215+ range, in 200-year retrospect, but these are the rare handful that seemingly been able to do this; hence, "stable" long-term 200-range IQ citation seem to be akin to attempting to run the 4-minute mile, get to approach absolute zero, or approach the speed of light, i.e. the close one gets, the harder it gets. Hence, at some gray area point, at or above the IQ 210 to 235 range is somewhat of a chimera, that only the distant future will be better equipped to judge and IQs above say 240 are unrealistic, akin to the finding that it is impossible to accelerate a body to the speed of light or to cool a system to absolute zero.

In spite of this “increasing steepness effect” associated with ceiling approaching IQs, there are some, e.g. Stephen Hsu (Ѻ)(Ѻ), who believe that scientists of the future will genetically engineer humans, like we currently do with chickens to get larger bodies, to make humans with IQs of 1000. This, however, is more akin to science fiction.

Overestimation | Issues
Clearly, form the examples cited above, those such as Sidis, De Mello, and Kearney did NOT have real IQs (or true IQs), say as compared to a Cox-Buzan IQ, 500-year retrospect, estimate of Da Vinci has having had an IQ of 200 or Goethe, the world's second biggest author (behind Shakespeare), to as having an IQ of 213. Some of this overestimation issue is captured well by American child prodigy turned physicist, biophysicist, social scientist, genius studies scholar, and reductionism defender John Platt:

“Lestrade (Ѻ) to be let loose on such a study is exactly as pathetic as for a subnormal waitress in the IQ of 90 range to try to measure the intellectual differences in college students.”
John Platt (1962), “The Coming Generation of Genius” (pg. 73)

This is embodied in the old saying that "genius recognizes genius", e.g. Platt recognized the genius of Percy Bridgman ranking him with an IQ of 180, which is about five points shy of his current estimate, based on what he actually did, in retrospect, and conversely that "genius recognizes lesser genius", as the Landau genius scale and Lev Landau being the prime example, and non-genius ability or work.

Moreover, going into the early 20th century, it has been estimated that accelerated learning psychologists, of niche schools of this sort, in American, estimate ratio IQs of children, in the 200 range, at about one per 1.8 years per 3-4 state range of population, or something to this effect.

Quotes
The following are related quotes:

“OK most IQ's use 100 as mean and 15 points per standard deviation so an IQ of 200 or above according to wolfram alpha would be 1 out of nearly 80 billion statistically. The world population was about 6.8 billion in 2009 so the fact that there would be one with IQ 200 is shocking but all these 200+ is just ridiculous.”
— Eddie Koski (Ѻ) (2012), “IQ:200+ | Smartest Person Ever (4 of 4)”, forum (Ѻ) post

“If anyone is interested in this – [claim] that Goethe had an IQ of 225 or whatever. Keep in mind IQ was invented in the twentieth century. Goethe who lived hundreds of years ago, never took any kind of IQ test, so the whole thing of claiming Goethe or Newton or whoever had an IQ of this or that is just pure speculation (and wrong one) – Google, "IQ Percentile and Rarity Chart" . They have a chart showing the percentage of population and odds for any given IQ. The odds of scoring 200 are 1 in 76 billion. The odds of scoring 201 are 1 in 119 billion, and the odds of scoring 202 are 1 in 190 billion. There are only 7 billion people on earth. That should be enough to settle this issue. No, Goethe didn't have an IQ of 225; that's a ridiculous made up definition of IQ. Note how this guy keeps making this silly claim over and over again. It cannot be true, unless he is giving Goethe children's test when he was a child.”
— Evi Tthought (Ѻ) (2015), “25 Smartest People Alive | Existive (2014) (5 of 5)”, forum post (Ѻ), Dec.

“I agree with Gladyshev’s 2012 statement that ‘Goethe's affinity can be interpreted on the basis of supramolecular thermodynamics. Changing of the Gibbs function occurring on the supramolecular structure level in complex systems (organisms). The affinity of Goethe is related to the phenomenon of sensory tropism’, but the reason Libb peddles Goethe and Hirata (although unlike Goethe, Hirata is the real deal) is that he thinks it allows him to peddle his ‘human chemistry’ BS, which in turn, he thinks will make it easier for him to peddle and sell his BS scam books onHuman Chemistry. Essentially his entire website [eoht.info] is a book scam operation to try and sell his book. It’s funny that he goes on to give the illusion that there are other posters that agree with him. He has done the same laughable tactic where he cites some quote from some anon poster on how brilliant he is and that becomes the proof that he supposedly has an IQ in the range of 170-220. For the record NO ONE has an IQ over 200 despite what anyone claims. Having said that I certainly would put Fields medalist Manjul Bhargava (Ѻ) ahead of Goethe any day.”

“If we go by the standard IQ rarity chart (that you can find anywhere) the rarity of scoring an IQ of 200 sd. 16 is about 1 in 5 billion. That's is theoretically (and approximately) 22 people who could have scored that high within the beginning of time.”
— Anon (2017), “Archimedes” (Ѻ), Hmolpedia Forum, Apr 2

“The highest deviation IQ test is the WISC-IV Extended Norms, at 210 SD16, or the Stanford-Binet 5 Extended Scales, at 225, and so take any 350 IQ estimate with a grain of salt.”
