AN EMPTINESS FINALLY HEAPED. THE SIGMA TEST

By Albert FRANK
(this article is published in ComMensal, Papyrus and Gift of Fire)

In 1999, a tragic emptiness appeared in the world of the " great" tests : For various reasons, the Mega, the Titan, The Power, The TFG shorts form of Cooijmans stopped being valid as tests of qualification, and the numerical section of the TFG long form has been suppressed.  
This emptiness has just been heapped : Hindemburg Melao Jr., founder of the Sigma Society (index.html) has created the " Sigma Test ", after a long and serious work, both in the realization of the test that in the establishment of norms. The test is available since September 2001.  
Who is Hindemburg Melao Jr., the founder of the Sigma Society? Born in Sao Paulo (Brazil) on January 15th 1972, he is a personality known in the world of chess. Melao has two world records in chess:  
- The longest announced checkmate in a simultaneous blindfold chess game, Sao Paulo, 1997 (mate in 12 moves, playing on 9 boards). This record is registered in the Guinness Book of Records, Brazilian Edition, 1998, pages 110 - 111.  
- The longest announced checkmate in a correspondence chess game: mate in 36 moves, in Special Class Tournament CXEB, published in Pi Society Journal - 05/00.  
He has written many relevant articles in the following fields: Mathematics, Physics, Astronomy, Psychology (problems concerning gifted children), and Research about the standardization of IQ tests.  
The Sigma Test : This test consists of 36 questions. These, weighted in ten levels of difficulties, are, above all, completely varied.  
What is particularly remarkable in this test ?  
- The increasing difficulty of the questions, that goes progressively from direct reasoning problems to questions needing a high power of reasoning using lateral (or divergent) thinking.  
- The questions concern a lot of various topics.  
- Very little preliminary knowledge seems to be required.  
- The standardization, obviously result of a long and serious work, is very clearly presented at the end of the test.  
- The weighted of the questions. It is practically the first time that, in a test, the " difficult " questions have a weight that seems proportional to the work and to the level of reasoning needed to solve them.  
The world of tests must thank Hindemburg Melao Jr. for having given him this test !

"The SIGMA test was one of the most interesting things I have done in the realm of puzzles because the later questions were so clever and had so many different levels of solution. I finished the test as a personal challenge, and it gave me great satisfaction. Some of the SIGMA test puzzles are REALLY beautiful. They are a work of art!"

(English Version) Dear Mr. Melao:

I found some interesting IQ test in Internet. However I have realized many of them are heavily cultural dependent. For instance, Dr. Hoefflin Power Test has rather interesting and difficult problems, however too many of them abuse of the mathematical abilities of the tester. The same problem has the test of Haselbauger and some others. I don’t mean they call for a Ph. degree in Mathematics, but it is clear than people with a strong mathematics background would get rather better scores than other people. Some others as Titan Ultra and Mega use verbal analogies which not only are heavily cultural dependent, also English speakers would get advantage from that.

The first time I saw the Sigma Test, I have to recognize that I didn’t like it as much as the Power Test or similar ones. Some ingenious problems of the second half seemed too arbitrary and without scientific interest for psicometry, as they didn’t have a unique solution and that makes me think they had a lack of objectivity. After answer questions 1 to 25 I found the others very vague. Even mathematical questions as the 31 which requires: first to figure out the theoretical model that the question is calling for and only them go for the second step: mathematically work it out. I haven’t found even one of those in Dr. Hoefflin tests, as those questions can be answered going directly to the second step.

Sigma test requires a strong convergent and divergent (lateral) thinking. Only a creative and deductive mind could get a high score in that test. If one test can tell an universal genius from other person who is only good at mathematics or verbal quizzes is the Sigma Test. Even a person without a mathematical knowledge, non native of the language of the test (no verbal analogies) could via questions 34, 35 and 36 get a very high score.

The scoring system is also new, and I am not only talking about the different weight of the questions, also as the tester has to explain the way he got the answer, eventually corrects answers the tester have gotten in a wrong way can be detected, so the IQ scores will not be dependent of the luck of the tester.

I agree with the creator of Sigma Test, the high IQ levels are more likely measured on intellectual production basis rather than using a test, however if any test can approximate better this is Mr. Hindemburg Melao Jr Sigma Test. We everybody thanks to Mr. Melao his contribution to the psicometry.

Luis Lara.


(Version Española) Querido Sr. Melao:

En Internet he encontrado algunos IQ test muy interesantes. Pero me he dado cuenta de que muchos de ellos son muy dependientes del nivel cultural del individuo. Por ejemplo el Power Test del Doctor Hoefflin, contiene unos problemas muy interesantes, sin embargo, creo que abusa de las habilidades matemáticas del que los toma. Y lo mismo le pasa a los de Haselbauer y otros más. Algunos como el Titán, Mega y Ultra contienen ejercicios de analogías que son muy culturalmente dependientes y que además serían más fáciles, obviamente, para los angloparlantes. Cuando me topé con el Sigma Test, he de reconocer que no me gustó tanto como el Power Test. Y algunos problemas de ingenio de la segunda mitad me parecían muy arbitrarios y sin interés, pues parecía que al no existir solución única carecían de la objetividad que debe de tener un IQ test. Después de responder a las preguntas de la 1 a la 25 las demás me parecían muy vagas. Pasó el tiempo y me fui dando cuenta de que el Sigma Test probablemente sea el mejor test de los que he visto nunca. El Sigma Test, además de habilidades deductivas, se ocupa del pensamiento divergente y de la creatividad, como el Power Test no podría nunca hacerlo. Las respuestas en los últimos problemas del Sigma no siempre son únicas, aunque exista una que es la mejor de todas. Creo que si un test podría distinguir entre un genio creativo como Leonardo da Vinci de una persona que simplemente tiene una buena capacidad matemática ése sería el Sigma Test. Además, al contrario que muchos otros test, personas sin conocimientos matemáticos pueden obtener puntuaciones IQ muy altas ya que las preguntas 26-30, 33-36 no requieren conocimientos matemáticos pero sí un alto, altísimo IQ para responder correctamente a las 35, 36.

El sistema de puntuación es también novedoso, permite puntuación parcial de un test para respuestas parcialmente correctas, cosa que otros test no permiten. Además, la nueva norma nos da mejores ideas acerca del IQ del testando.

La idea de que el verdadero IQ del testando, especialmente para los valores más altos del IQ, se ve mejor en la producción intelectual de la persona más que en un test de IQ me parece verdaderamente correcta. Por eso dice usted que los miembros de Mega no son tan inteligentes como un premio Nobel de ciencia medio. No obstante creo que el Sigma Test es más cercano, puede reflejar más exactamente, el desempeño mental de alguien en la vida profesional de lo que lo pueden hacer los test de Hoefflin u otros. Esto se debe a que las preguntas del Sigma no requieren un solo tipo de pensamiento sino varios, además están basadas en situaciones concretas que son ó parecen reales. Le felicito por su contribución la psicometría.

Luis Lara.

Thought tests and puzzles always have amused me, this is the first IQ-test I have bothered to send in for scoring. I found myself increasingly absorbed by the intellectual art behind the questions in this test. Together with achievement, I rank creativity on top of the scale, which you elegantly have combined with divergent / convergent thinking. Thank you for creating a great test. I now look forward to take the Sigma Test VI! Provided my scores are sufficient, I intend to apply for membership in the Sigma Society.

The Sigma Society---Creative Fusion1  

I've just translated the Sigma Society Test -- which claims to test up to IQ 202, by levels (sigma) -- into English. Though I am uncertain about the scale, (I don't believe it could differentiate any higher than the 180-190+ level) the test itself is almost a relief.  

The problems are almost Pascal-like and highly creative. The test begins with basic Mensa/WAIS/Binet questions, which progressively turn into more interesting problems like correcting a false conclusion about Fermat's Theorem deriving from the Pythagorean, measuring lung capacity within a $ budget, approach diameters for a planet (from a parachute POV), weighing the Graphite on a piece of paper, developing methods for estimating a stranger's vocabulary, getting out of a cannibalistic situation by picking eggs and constructing a Sphere of Invisibility. 

Now I may be mistaken, but these seem much closer to the problems for which Vinci and Pascal are famous. 

Creative and Logical, with a high degree of unconventional thought required. I hear it's decently normed, too -- 

Email me if you want a copy of the translation.

From Stephen Reejis (United States, Boston University, member of Cerebrals Society):

Melao,

Thanks for the detailed statistical information pointers. Rarely does one get in these or even non-statistical but scientific circles the breadth of coverage you have touched upon. But frequently "scientists" make all sorts of statistical inferential slippages, although what everyone remembers is only the "punchline" of their papers. This is very useful exposure, and I will try to delve into many of the areas you have brought up.

A few of the links don't work though. The other links are very good.

And since you are here, although I have not submitted the original Sigma test (not that much money ), I must say that it is a completely beautiful excercise. I really appreciate the degree of thought that goes into the items and it has given me a lot of pleasure to think about some of the items ( I particularly like the one about the boiled/unboiled eggs with the cannibals) and a few others at that level (although the hardest ones have me perfectly stumped). I have two silver math IMO friend and an applied math major friend and in my mind, the quality of their general thought and ability is amazing (I am a strong believer that mathamatical ability is the strongest marker for intellect, very beautifully tested in IMO-style questions). Your test combines creativity and brings a tangibility to exactly what is the complexity involved in an item of high difficulty, and makes the item accessible to the non-specialist (contrast with IMO questions, which require at least a basic understanding of some areas). Congratulations to you for it

Reejis
