or, the High-IQ Directories, Listings, Rankings

One
of the great wildernesses of the international high-IQ communities, as
delineated cells of IQ test-takers with scores on a variety of tests at a range
of rarities with generalized and specialized communities, are the high-IQ
directories, listings, and rankings.

With
each, they tend to list from highest to lowest scores as reported on a variety
of tests. In turn, this means the directories and the listings can be
considered directories and listings, generically, and rankings, specifically.

Therefore, for most, the most precise terminology would be “rankings” rather than “directories” or “listings.” Although, all terms work in the patois of the high-IQ community if not considering differences in generic or specific implied meanings.

This article will explore some of them[1]. Those rankings include ESOTERIQ Society of Masaaki Yamauchi (incorporative of some of the Giga Society of Paul Cooijmans), GENIUS High IQ Network of Dr. Iakovos Koukas, GFIS IQ List/Dinghong Yao IQ Ranking List of Dinghong Yao, GIFTED High IQ Network of Dr. Iakovos Koukas, Hall of IQ Scores of Konstantinos Ntalachanis, Hall of Sophia of Guillermo Alejandro Escárcega Pliego, HRIQ Ranking List of Qiao Hansheng, Mahir Wu Ranking List of Mahir Wu, Real IQ Listing of Dr. Ivan Ivec, Svenska IQ-Listan of Hans Sjöberg and Alexi Edin, VeNuS Ranking List of Domagoj Kutle/Domagoj Domo Kutle, WIQF Listing[2] of Marco Ripà and Dr. Manahel Thabet, World Famous IQ Scores of Dr. Ivan Ivec, World Genius Directory of Jason Betts, and World Highest IQ Scores of Mislav Predavec.

For
some further information with most actual or potential founding dates, and
founders, and two highest score claimants at present, associated tests, scores,
and standard deviations, please see further below:

ESOTERIQ Society of Masaaki Yamauchi founded in 2001 with the highest claimed scores at an IQ of 194.68 (S.D. 15) on the CIT5 by Dr. Heinrich Siemens and on RIDDLES by Yukun Wang. Its website stated:

The ESOTERIQ membership is separated into either the GIGA society members or non-the GIGA society members.  Any GIGA member is always automatically welcomed to the ESOTERIQ society.    

Non-GIGA members are required belonging to at least one of the following societies in advance and one test would be limited only per one candidate. Hence, the same tests are prohibited to be listed for the different individuals. 

A member or subscriber of the OLYMPIQ society (above IQ190.sd15 performance) 

A listed member of the World Genius Directory(above IQ190.sd15 performance) 

A non-belonging candidate of the above may also be considered on a case by case basis. 

WAIS-Ⅳ and Stanford-Binet-Ⅴ are invalid as the ESOTERIQ membership. 

The membership fee is free.

These
must be clerical errors, as the scores remain inclusive of IQs at 190 (S.D. 15)
and, therefore, should state “at or above” rather than “above” alone.

GENIUS High IQ Network of Dr. Iakovos Koukas founded in 2014 with the highest claimed score at an IQ of 208 (S.D. 15) on MATRIQ by Iakovos Koukas (first attempt) and the second-highest score at an IQ of 194 (S.D. 15) on MATRIQ by Tor Arne Jørgensen (second attempt).

GFIS IQ List/Dinghong Yao IQ Ranking List of Dinghong Yao founded in 2017 (maybe) with the highest claimed score at an IQ of 192 (S.D. 15) on the Logicaus Strictimanus 24 (LS24) by Mislav Predavec and the second-highest claimed scores at an IQ of 190+ (S.D. 15) on the Numerus Classic by Wen-Chin Sui and Challenger by Junxie Huang.

GIFTED High IQ Network of Dr. Iakovos Koukas founded in 2014 with the highest claimed score at an IQ of 208 (S.D. 15) on MATRIQ by Iakovos Koukas (first attempt) and the second-highest score at an IQ of 194 (S.D. 15) on MATRIQ by Tor Arne Jørgensen (second attempt).

Hall of IQ Scores of Konstantinos Ntalachanis founded in 2016 with the highest score claimed at an IQ of 230 (S.D. 15) by Konstantinos Ntalachanis on the D.O.S. and a second-highest score claimed at an IQ of 216 (S.D. 15) by Ken Luo on RIDDLES.

Hall of Sophia of Guillermo Alejandro Escárcega Pliego
founded in 2019 (maybe) with the highest claimed scores on a variety of tests
differentiating historical and current figures, prominent and not.

HRIQ Ranking List of Qiao Hansheng with the highest claimed score at an IQ of 195+ (S.D. 15) on MATRIQ by Iakovos Koukas and the second-highest claimed score at an IQ of 191 (S.D. 15) on the Qoyman Multiple-Choice #3 by Dr. Evangelos Katsioulis.

Mahir
Wu Ranking List of Mahir Wu founded in 2017 (maybe) with the highest
claimed scores at an IQ of 190+ (S.D. 15) on Challenger by Junxie Huang and on
Free Fall (Part II) by Jose Gonzalez Molinero.

Real IQ Listing of Dr. Ivan Ivec (also links to Jason Betts) founded in 2012 (maybe) with the highest claimed score at an IQ of 181.20 (S.D. 15) by Luca Fiorani and the second-highest claimed score at an IQ of 174.90 (S.D. 15) by Erik Hæreid.

Svenska IQ-Listan of Hans Sjöberg and Alexi Edin founded in 2016 (maybe) with the highest claimed score at an IQ of 180 (S.D. 15) on the Cogitatus Logicae by Stefan Langemalm and the second-highest claimed score at an IQ of 172 (S.D. 15) on GENE V3 by Tonny Sellen.

VeNuS Ranking List of Domagoj Kutle/Domagoj Domo Kutle founded in 2017 (maybe). It utilizes an idea of Jason Betts of TrueIQ with the Venus score as a composite of the highest scores.

Although, as noted by Darryl Miyaguchi, in previous writings, this has antecedents in title, as stated in “A Short (and Bloody) History of the High I.Q. Societies” (2000), “The method, called the Ferguson formula, after George A. Ferguson, a well-known psychometrician, involves estimating the ‘true’ I.Q. that would be required to achieve high scores on imperfectly-correlated tests, which is generally higher than the average of the scores on the tests used.”

The highest claimed Venus score is 558 of Konstantinos Ntalachanis and the second-highest claimed Venus score is 552 of Dr. Heinrich Siemens.

WIQF Listing of Marco Ripà and Dr. Manahel Thabet founded in April 2014 with the highest claimed score at an IQ of 229.44 (S.D. 24)/ 180.90 (S.D. 15) on 1 unnamed test by Varidh Katiyar and the second-highest claimed score at an IQ of 220.00 (S.D. 24)/175 (S.D. 15) on 1 unnamed test by YoungHoon Kim/YoungHoon Bryan Kim.

World Famous IQ Scores of Dr. Ivan Ivec founded
in 2011 (maybe) with the highest claimed scores at an IQ of 190+ (S.D. 15) on
Numerus by Dong Khac Cuong and Tianxi Yu, on Free Fall Part II by José González
Molinero and Junxie Huang, and on Numerus Classic by Wen-Chin Sui.

World Genius Directory of Jason Betts founded in 2015 (maybe) with the highest claimed score at an IQ of 198 (S.D. 15) on the NVCP by Dr. Evangelos Katsioulis and the second-highest claimed score at an IQ of 195 (S.D. 15). on the CIT5 by Dr. Heinrich Siemens.

World Highest IQ Scores of Mislav Predavec[3] founded in 2007 with the highest claimed score at an IQ of 188 (S.D. 15) on the Ls 60 by Mislav Predavec and the second-highest claimed score at an IQ of 187.5 on the Logicaus strictimanus 24 by Mislav Predavec.

Based on these provisions, the founders of the rankings have a tendency to list themselves on the listings. In several, the founders rank themselves as the highest-scoring member of the ranking.

This happens with the GENIUS High IQ Network of Dr. Iakovos Koukas, GIFTED High IQ Network of Dr. Iakovos Koukas, Hall of IQ Scores of Konstantinos Ntalachanis, and World Highest IQ Scores of Mislav Predavec.

Now, a large number of rankings of the highest IQs, or the highest claimed IQs rather, exist online. Many at or above 6.00-sigma, in other words. When examining all of the above rankings, those individuals include the below names.

All,
according to the rankings themselves, the scores at or above 6.00-sigma with
individuals and tests if available, uncertain if all individuals themselves
make these claims. Therefore, consider the below relative only to the
individuated rankings in and of themselves, please:

World
Highest IQ Scores of Mislav Predavec

None claimed above 6.00-sigma. However, one claimed at 187.5 (S.D. 15) on the website, on the Ls 24 or the Logicaus strictimanus 24 would match the same test as the World Genius Directory with the claimed score of 192 (S.D. 15).

The same test and different scores with the World Genius Directory claimed at 6.12-sigma and the World Highest IQ Scores claimed at 5.83-sigma. Both claimed scores by Mislav Predavec; these may represent different attempts or clerical errors.

In this
manner, we can produce a unified picture of the claims to scores at or above 6.00-sigma
by living individuals. With the rankings, while elimination of redundancy or duplication
of names with minor spelling or accent variations, we can produce a claimed
score ranking.

A claimed score ranking of individuals at or above 6.00-sigma from the current crop of better-known living highest-IQ rankings (directories, listings, and rankings):

Former ESOTERIQ Members

  • (YoungHoon Kim/YoungHoon Bryan Kim at 6.00-sigma or higher, potentially, formerly a member; no longer on the listing.)
  • (Cavan Cohoes at 6.00-sigma or higher, potentially, formerly a member; no longer on the listing.)
  • (Tanxi Yu at 6.00-sigma or higher, potentially, formerly a member; no longer on the listing.)
  • (Luca Fiorani at 6.00-sigma or higher, potentially, formerly a member; no longer on the listing.)
  • (Jose Molinero at 6.00-sigma or higher, potentially, formerly a member; no longer on the listing.)
  • (Junxie Huang at 6.00-sigma or higher, potentially, formerly a member; no longer on the listing.)
  • (Sanghyun Cho at 6.00-sigma or higher, potentially, formerly a member; no longer on the listing.)
  • (Dawid Skrzos at 6.00-sigma or higher, potentially, formerly a member; no longer on the listing.)

With these 29 claimed by the rankings, while potentially only claimed by the Hall of Sophia for some, the range of sigmas would be 6.00-sigma to unmeasurable or, alternatively 6.00-sigma, to 8.67-sigma. All this on the premise of the accuracy of the testing and the claims of scores on tests connected to IQ scores.

The
rarities out of the general population implied by the sigmas including and
after 6.00 to, for example, 6.80-sigma would mean the following, as examples:

  • 6.00-sigma is 1 out of 1,009,976,678 people in the general population.
  • 6.07-sigma is 1 out of 1,525,765,721 people in the general population.
  • 6.13-sigma is 1 out of 2,314,980,850 people in the general population.
  • 6.20-sigma is 1 out of 3,527,693,270 people in the general population.
  • 6.27-sigma is 1 out of 5,399,067,340 people in the general population.
  • 6.33-sigma is 1 out of 8,299,126,114 people in the general population.
  • 6.40-sigma is 1 out of 12,812,462,045 people in the general population.
  • 6.47-sigma is 1 out of 19,866,426,228 people in the general population.
  • 6.53-sigma is 1 out of 30,938,221,975 people in the general population.
  • 6.60-sigma is 1 out of 48,390,420,202 people in the general population.
  • 6.67-sigma is 1 out of 76,017,176,740 people in the general population.
  • 6.73-sigma is 1 out of 119,937,672,336 people in the general population.
  • 6.80-sigma is 1 out of 190,057,377,928 people in the general population.

And so on, given the rarity past somewhere between 6.67-sigma to 6.73-sigma, and given the number of people who have lived on the planet in the history of the species, even in the present day, the scores on alternative tests compared to mainstream intelligence tests become inflated by the nature of the rarities claimed in addition to the number of individual test-takers claiming scores above or at 6-sigma.

Even with the elimination of scores claimed only on the rankings, or only the scores of individuals who themselves claim the scores on the alternative tests at or above 6-sigma, the continual issues of the rarities and the number of individuals glare forward.

In short, even if verified as accurate scores, as a premise of assuming
trust in the scores claimed, the scores themselves, by individuals, can be
claimed as inflated beyond the real metrics. Indeed, when on psychometric
validity and reliability grounds, these remain alternative tests.

As such, these alternative tests lack the depth of reliability and validity found in the mainstream intelligence tests developed over decades and decades, even more than a century, so alternative tests compared to mainstream intelligence tests, including, as was noted to me, an alternative test (NVCP, NVCP-E, NVCP-R) made into a mainstream intelligence test.

Which is to say, as was described succinctly by one individual, the French branch of Harcourt Assessment acquired Pearson Education and made the NVCP-E, in particular, into the EPC, while the one highest-IQ claimant claims the score on the NVCP-R, not the NCVP-E. Both from Dr. Xavier Jouve; both test constructor and tested knew one another.

Indeed, Katsioulis took the NVCP-E twice and the NVCP-R twice for a first attempt and a second attempt on both tests as stated in “General information“:

IQ 205 , sd 16, NVCP-R [Rasch equated raw 49/54] • 2002
IQ 196 , sd 16, Qoymans Multiple Choice #3 [ceiling] • 2003
IQ 192 , sd 16, NVCP-E [Rasch equated raw 35/40] • 2002
IQ 186 , sd 16, NVCP-R [Fluid Intelligence Index Score] • 2002
IQ 183 , sd 16, NVCP-E [Fluid Intelligence Index Score] • 2002
IQ 183 , sd 16, Cattell Culture Fair III A+B [ceiling-1] • 2003
IQ 180+ sd 16, Bonnardel BLS4 – 2T [ceiling] • 2003
IQ 180+ sd 16, WAIS-R [extrapolated full scale] • 2002

Thusly, and if assuming a reasonable principle of first attempts resulting in lower scores, one comes to the first attempt on the NVCP-E at an IQ of 183 (S.D. 16) and on the NVCP-R at an IQ 186 (S.D. 16), and a second attempt on the NVCP-E at an IQ of 192 (S.D. 16) and on the NVCP-R at an IQ of 205 (S.D. 16).

In turn, as with the WAIS-R and the Bonnardel BLS4 – 2T scores listed above, and if assuming the seriousness in the effort of the experimental psychologist, Dr. Xavier Jouve, while ignoring relational conflict of interest between the two of them, we can come to the IQ scores from the mainstream intelligence tests at 175+ (S.D. 15), on the WAIS-R and the Bonnardel BLS4 – 2T, to 177.81 (S.D. 15) to 180.63 (S.D. 15), on the NVCP-E (first attempt) and NVCP-R (first attempt), respectively.

Since done by an experimental psychologist, this seems more serious than the MATRIQ and the score of Iakovos Koukas, though a first attempt on the MATRIQ.

One can see some of the highest claimants with WAIS, or a trusted mainstream intelligence test, score at 164 (S.D. 15), or 4.27-sigma, for Dr. Iakovos Koukas and 175 (S.D. 15), or 5.00-sigma, for Dr. Evangelos Katsioulis, while each, individually, claims a sigma of 6.93-sigma on MATRIQ and a 6.53-sigma on NVCP-R, respectively.

However, the WAIS-R scores for Katsioulis match the NVCP-E and NVCP-R first attempt scores far more than the MATRIQ first attempt and the WAIS score for Koukas.

Nonetheless, the N on all tests remains too low. Those with specific psychometric reliability and validity relate to the mainstream intelligence tests, as in aimed at measurement of the proposed scientific construct or psychological construct of general intelligence.

Thus, you see the massive differential between alternative tests and mainstream intelligence test scores for two of the highest-IQ in the world claimants.

This logic can be replicated across the spectrum for more scientific reliability and validity when making loose individual comparisons or larger contrasts, too, between alternative test scores (and scorers), seen mostly on these rankings, and mainstream intelligence tests, seen little on these rankings.

This leaves open the questions about individuals making claims about
themselves or individuals assessed and claimed in history. Both more dubious,
in different ways, than the rankings, though living rankings have import for
individuals who wish for communal recognition of recognized test scores and
claimed IQs.

Catherine
Morris Cox made a ranking of 300. James Cattell made the Cattell 1,000. Jim
Glenn made a list without specific IQs attached to the names. John Platt made a
ranking with none at or above IQ 200, or without a specific IQ attached to the
name.

Libb Thims made the ranking of 1,000 geniuses in history. The late Tony Buzan made a ranking. Same with the late Tony Buzan and Raymond Keene. Will Durant listed some without any at or above IQ 200.

Catherine
Morris Cox ranked those above IQ 200 as Johann Wolfgang von Goethe (IQ 210),
Gottfried Wilhelm (von) Leibniz (IQ 205), Hugo Grotius (IQ 200), and Thomas
Wolsey (IQ 200).

Libb
Thims made the ranking of those at or above IQ 200 with Johann Wolfgang von
Goethe (IQ 225), Isaac Newton (IQ 220), Albert Einstein (IQ 215), James Clerk
Maxwell (IQ 210), Willard Gibbs (IQ 210), Rudolf Clausius (IQ 205), Leonardo Da
Vinci (IQ 200), and Thomas Young (IQ 200).

The late Tony Buzan included at or above IQ 200 as
Leonardo Da Vinci (IQ 220), Johann Wolfgang von Goethe (IQ 215), William Shakespeare (IQ 210), and Albert Einstein (IQ 205).

The late
Tony Buzan and Raymond Keene ranked those above IQ 200 as Leonardo Da Vinci (IQ
220), Johann Wolfgang von Goethe (IQ 215), William Shakespeare (IQ 210), and
Albert Einstein (IQ 205), too.

Even so, there exist self-claimed IQs or IQs claimed about some, as in media hype or inflated IQs.

In such a manner, there should be skepticism and more careful observation as to even the most minimal criteria of the type of test (alternative test versus mainstream intelligence test), the first attempt on the test or more than the first attempt on the test, and the real name or a fake name/pseudonym on the test, or, further, the financial conflicts of interest or other conflicts of interest inherent in the claimed scores or the rankings declared, as such.

Individuals have taken tests under false names, more than once, and on only alternative tests, for example. Outside of those considerations, these become increasing red flags, including if a difference between a mainstream intelligence test versus an alternative test, as can be noted by Libb Thims in a decent manner.

For
example, outside of the genius listing, Libb Thims listed inflated IQs, where
one needs to remain cautious: Adragon De Mello, Ainan Cawley, Michael Kearney,
Maria Dos Marinos, Marnen Laibow-Koser, Evangelos Katsioulis, Avi Ben-Abraham,
Rick Rosner, Marilyn Savant, Visalini Kumaraswamy, Marta Rodiguez, Gena Leung,
Nathan Leopold, Christopher Langan/Christopher Michael Langan, Michael Grost, Sho Yano, Dylan Jones, Naida Camukova, Edith Stern,
Christopher Harding, Daniel Simidchieva, Garry Kasparov, Philip Emeagwali,
Bobby Fischer, Merrill Kenneth Wolf, Grady
Towers, Pranav Veera, Judith Polgar, Jacob Barnett, Victoria Cowie, Colin
Carlson, Oscar Wrigley, and Elise Tan-Roberts (link here).

Parents want their kids to be geniuses. The culture and media like the stories about genius going well and going awry. Individuals want to join the high-IQ community at the higher-IQ levels, and so on. These are motivations for lying, as happens, often, in these areas, apparently.

Although,
by and large, the efforts are honest and sincere. These issues or concerns
arise rather pervasively and, therefore, require a conscious attention about
them.

[1] In “Christian Sorensen on Measuring and Ranking the Highly Intelligent,” it states:

There are a ton of online sources via articles including “The 40 smartest people of all time,” “30 Smartest People Alive Today,” “8 People with Higher IQs Than Einstein,” “Here Is The Highest Possible IQ And The People Who Hold The World Record,” “25 Highest IQ’s Throughout History,” “The 50 Greatest Living Geniuses,” “21 Celebrities With Surprisingly High IQs,” “World’s Most Intelligent People 2010 – Intelligent People – Highest IQ,” “Feeling accomplished yet? Here is a list of people whose IQ levels have created records time and again,” “Who has the highest recorded IQ of all time?,” “Of All Things: Which president had the highest IQ?,” “Talk About Hidden Genius: These Are The Celebrities Boasting The Highest IQs,” “24 of the smartest people who ever lived,” “Famous Historical Genius IQs,” “The Smartest and Least Brainy Presidents, by IQ Scores,” “An 11-Year-Old Just Earned the Highest IQ Score Possible,” “What Is The Highest IQ Possible You Can Achieve?,” “What is the highest IQ ever measured in a human?,” “Dr Evangelos Katsioulis has the World’s Highest IQ,” “The Time Everyone “Corrected” the World’s Smartest Woman,” “The 13 Presidents with the Highest IQ Scores,” “Who Has the Highest IQ in the World? 35 People Who Are Even Smarter Than Einstein,” “​TOP 10 PEOPLE HAVE HIGHEST IQ SCORES IN THE WORLD (P.2),” “Meet Marilyn Vos Savant, The Woman With The World’s Highest IQ,” “The World’s 50 Smartest Teenagers,” “These 26 Celebrities Have The Highest IQ In Hollywood… #17 Is Pretty Much A Genius!,” “10 People With The Highest IQ In The World,” “The Man With The Highest IQ In The World Doesn’t Think He’s Very Smart At All,” “Top 12 People with Highest IQ in the World,” “Top 10 Women with Highest IQ in the World,” “The Massive List of Genius – People With the Highest IQ,” “Highest IQ Scores in History,” “A 3-year-old boy has just become the youngest member of Mensa UK, the largest international high IQ society,” and others.  It comes down to partial and questionable listings, individual profiles, children, celebrities, and American presidents. Then it’s a smattering of probably truly more obscure materials. Outside of the straight gossip-level journalism, there are a number of listings such as GENIUS High IQ Network, Gifted High IQ Network, Hall of IQ scores, HRIQ Ranking List, Mahir Wu Ranking List, VeNuS Ranking List, World Famous IQ Scores, World Genius Directory, World Highest IQ Scores, GFIS IQ List, WIQF Listing, and Real IQ Listing.
