"All our science, measured against reality, is primitive and childlike, and yet it is the most precious thing we have." Albert Einstein






"When a mathematician engaged in investigating physical actions and results has arrived at his own conclusions, may they not be expressed in common language as fully, clearly, and definitely as in mathematical formulae? If so, would it not be a great boon to such as well to express them so, translating them out of their hieroglyphics that we might also work upon them by experiment?" Michael Faraday




Definition of IQ : What is IQ?

IQ (intelligence quotient) = (Mental Age / Chronological Age) x 100.

The IQ of a child between the ages of 5 to 16 years old is calculated by dividing the child's mental age by his chronological age and then multiplying the result by 100. If a 10 year old child performs mentally at a 10 year old level, the IQ is calculated as 10 divided by 10 equaling 1, and multiplying the 1 by 100 equals an IQ of 100. If the 10 year old child mentally performs at a 20 year old level, then 20 over 10 equals 2, and multiplying 2 by 100 equals an IQ score of 200.

Adult IQ is calculated by supervised IQ testing. Adult IQ scores are specific to each IQ test and are not interchangeable between one IQ test and another. Membership qualifications to most high IQ societies require percentile ratings instead of IQ scores.

The IQ formula (MA/CA) x 100 = IQ was created as an indicator, not based on mathematical rules. The formula could have been (MA/CA)x10 or (MA/CA)x1000. IQ scores are relative numbers, of no real measurement other than to show relative differences of measurable mental performance between different people taking similar tests.




"The artistic genius wants to give pleasure, but if his work is on a very high level, he may easily lack people to appreciate it; he offers them food, but no one wants it. That gives him a sometimes ludicrously touching pathos; for basically he has no right to force pleasure on men. His pipe sounds, but no one wants to dance. Can that be tragic?" Friedrich Nietzsche - Human All Too Human




Average IQ, Gifted IQ, Genius IQ


An IQ score of 100 is average. Only one person in the world has an average IQ. Half of everyone else has a higher IQ, and the other half has a lower IQ. As IQ scores increase, so do opinions differ on what marks gifted and genius. IQ ratings are generally relative to the personal opinion and view of the person being asked (a 6'6" tall man may appear tall to a 5' tall man, but an 8' tall man thinks everyone to be short).

Generally, average IQ is about 90 to 115, talented is about 115 to 125, gifted is about 125 to 140, and about 140+ is commonly believed as having the potential for genius. It is important to note that whatsoever environment a person lives in, it is that which the person will deem normal, and all terms about intellectual levels are only relative to the individual's own personal level.




"I am attacked by two very opposite sects, the scientists and the know-nothings. Both laugh at me, calling me 'the frogs' dancing master'. Yet I know I have discovered one of the greatest forces in nature". Luigi Galvani, Italian physicist (1737-1798),accredited discoverer of electrically-induced muscle contraction: galvanism.




Traits of People with High IQ

Individuals with high IQs are humans just like everyone else, with similar personality strengths and weaknesses as everyone else. Some high IQers are nice, some are not so nice, and each individual has idiosyncrasies just as do all humans.

High levels of intelligence are commonly accompanied with a greater potential for simultaneously exhibiting above average skills in several fields (g and multiple intelligence). Extremely talented individuals do not easily recognize their own traits as being anything except common because there are no known higher levels of talent to compare the individual's talent to.




"In order that thinking might not degenerate into "metaphysics", or into empty talk, it is only necessary that enough propositions of the conceptual system be firmly enough connected with sensory experiences and that the conceptual system, in view of its task of ordering and surveying sense experience, should show as much unity and parsimony as possible." Albert Einstein




SQ (Sensory Quotient) Scoring

Beyond Prodigies book cover

Update for March 22, 2013 — the new prodigies book is now available through Barnes&Noble.
Much of the book's information is based on SesquIQ's SQ project, and since the book details some of the features within the SQ classifications of cognition the previous SQ tests have now been halted and no scoring will be given except for the new SQ tests.

SesquIQ has helped to develop the SQ (sensory quotient) tests. The scoring method measures differences of conscious sensorial perception. Sensorially talented individuals are able to perceive and be mentally cognizant of details that the majority of other people may not recognize except at the subconscious level. A SQ score of 100 is average for over 99.9% of all tested individuals.

One advantage of SQ as it applies to intelligence is that the increased conscious sensory input results in increased information for the mind to work with. All expressed intelligence relies on an individual having sensorially experienced a thing first-hand. With increased information input, the mind is able to correlate more data and arrive at a more useful and logical conclusion than if there were little information available.

Primarily due to frequent public misinterpretations of SQ scoring, the SQ scoring method temporarily adopted a method that visually appeared similar to IQ scoring. SQ scores of 90, 180, 270, 360, and 450 became 100, 125, 150, 175, and 200 respectively. Pre-July 2005 SQ scores were adjusted accordingly. Instead of relating 90 degrees to each level, the formula simply added 25 points per deviation. Actual scores are unimportant, it is the percentile ranking that holds importance, and percentile rankings for each level remained unchanged relative to pre-July 2005 scores. Nevertheless, since the SQ scoring method is unique and not so easily reduced down to a two dimensional mathematics as like IQ, SQ scoring has returned to the original method.
