High IQ Society
A high-IQ society is an organization that limits its membership to people who have attained a specified score on an IQ test, usually in the top two percent of the population (98th percentile) or above. These may also be referred to as genius societies. The largest and oldest such society is Mensa International, which was founded by Roland Berrill and Lancelot Ware in 1946. Entry requirements High-IQ societies typically accept a variety of IQ tests for membership eligibility; these include WAIS, Stanford-Binet, and Raven's Advanced Progressive Matrices, amongst many others deemed to sufficiently measure or correlate with intelligence. Tests deemed to insufficiently correlate with intelligence (e.g. post-1994 SAT, in the case of Mensa and Intertel) are not accepted for admission. As IQ significantly above 146 SD15 (approximately three-sigma) cannot be reliably measured with accuracy due to sub-test limitations and insufficient norming, IQ societies with cutoffs significantly h ...

Intelligence Quotient
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. The abbreviation "IQ" was coined by the psychologist William Stern for the German term ''Intelligenzquotient'', his term for a scoring method for intelligence tests at University of Breslau he advocated in a 1912 book. Historically, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months. The resulting fraction (quotient) was multiplied by 100 to obtain the IQ score. For modern IQ tests, the raw score is transformed to a normal distribution with mean 100 and standard deviation 15. This results in approximately two-thirds of the population scoring between IQ 85 and IQ 115 and about 2.5 percent each above 130 and below 70. Scores from intelligence tests are estimates of intelligence. Unlike, for example, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intertel
Intertel (previously the International Legion of Intelligence) is a high-IQ society founded in 1966, that is open to those who have scored at or above the 99th percentile (top 1%) on one of various standardized tests of intelligence. It has been identified as one of the notable high-IQ societies established since the late 1960s with admissions requirements that are stricter and more exclusive than Mensa. History and goals Intertel was founded in 1966 by Ralph Haines, following the example of Roland Berrill and Lancelot Ware (founders of Mensa), who wanted to create an association adapted to the gifted needs without any specific restriction of admission (with the exception of a minimum IQ). Intertel thus became the second oldest organization of this kind, Mensa being the first. The name "Intertel" derives from ''International Legion of Intelligence,'' and its members are still known as "Ilians". The organizations has three purposes, stated in its constitution: * Encouragin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mega Society
The Mega Society is a high IQ society open to people who have scored at the one-in-a-million level on a test of general intelligence claimed to be able to discriminate at that level. It was founded in 1982 by Ronald K. Hoeflin to facilitate psychometric research. The public profile of the Mega Society increased with the publication of the Mega Test in 1985 by Hoeflin. Criteria for acceptance No professionally designed and validated IQ test claims to distinguish test-takers at the one-in-a-million level of rarity of score. The standard score range of the Stanford-Binet IQ test is 40 to 160. The standard scores on most other currently normed IQ tests fall in the same range. A score of 160 corresponds to a rarity of about 1 person in 30,000 (leaving aside the issue of error of measurement common to all IQ tests), which falls short of the Mega Society's 1 in a million requirement. IQ scores above this level are dubious as there are insufficient normative cases upon which to base a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prometheus Society
The Prometheus Society is a high IQ society, similar to Mensa International, but much more restrictive. The entry criterion, achievable by a number of tests, is designed to be passable by 1 in 30,000 of the population, while Mensa entry is achievable by 1 in 50. The society produces a magazine, ''Gift of Fire'', published ten times per year. History Background An earlier organization, Mensa International, was founded by Roland Berrill and Lancelot Ware, who noted from their first conversation that although they came from different backgrounds, they were able to communicate and had much in common. They hypothesized that what they had in common was intelligence, and decided to see if a society of people selected for intelligence (using the only means then available, IQ tests) would also have much in common. They decided to focus on people whose IQ test scores would place them at or above the 98th percentile. Beyond the 98th percentile In the late 1930s Leta Stetter Hollingworth's ...

Triple Nine Society
The Triple Nine Society (TNS) is an international high IQ society for adults whose score on a standardized test demonstrates an IQ at or above the 99.9th percentile of the human population. The society recognizes scores from over 20 different tests of adult intelligence. The society was founded in 1978 and is a non-profit, 501(c)(7) organization incorporated in Virginia, USA. , it reports a member base of over 1,900 adults in 50 countries. Organization Executive Committee Officers serve for two-year terms. Six are elected and three are appointed. In 2015 TNS established a 501(c)(3) subsidiary charitable organization, the Triple Nine Society Foundation, to provide scholarships to intellectually gifted students pursuing higher education goals, to educate the public about the needs of very intellectually gifted people, and for other charitable work. Communication TNS publishes a bimonthly journal, ''Vidya'', which contains articles, poetry and other creative content contribute ...

Standardized Test
A standardized test is a test that is administered and scored in a consistent, or "standard", manner. Standardized tests are designed in such a way that the questions and interpretations are consistent and are administered and scored in a predetermined, standard manner. Any test in which the same test is given in the same manner to all test takers, and graded in the same manner for everyone, is a standardized test. Standardized tests do not need to be high-stakes tests, time-limited tests, or multiple-choice tests. A standardized test may be any type of test: a written test, an oral test, or a practical skills performance test. The questions can be simple or complex. The subject matter among school-age students is frequently academic skills, but a standardized test can be given on nearly any topic, including driving tests, creativity, athleticism, personality, professional ethics, or other attributes. The opposite of standardized testing is ''non-standardized testing'', in w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Deviation
In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. Standard deviation may be abbreviated SD, and is most commonly represented in mathematical texts and equations by the lower case Greek letter σ (sigma), for the population standard deviation, or the Latin letter '' s'', for the sample standard deviation. The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same unit as the data. The standard deviation of a popu ...

Raven's Progressive Matrices
Raven's Progressive Matrices (often referred to simply as Raven's Matrices) or RPM is a non-verbal test typically used to measure general human intelligence and abstract reasoning and is regarded as a non-verbal estimate of fluid intelligence. It is one of the most common tests administered to both groups and individuals ranging from 5-year-olds to the elderly.Kaplan, R. M., & Saccuzzo, D. P. (2009). Standardized tests in education, civil service, and the military. Psychological testing: Principles, applications, and issues (7 ed. pp. 325–327). Belmont, CA: Wadsworth. It comprises 60 multiple choice questions, listed in order of increasing difficulty. This format is designed to measure the test taker's reasoning ability, the eductive ("meaning-making") component of Spearman's ''g'' (''g'' is often referred to as general intelligence). The tests were originally developed by John C. Raven in 1936.Raven, J. C. (1936). ''Mental tests used in genetic studies: The performance of re ...

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found ...

Stanford–Binet Intelligence Scales
The Stanford–Binet Intelligence Scales (or more commonly the Stanford–Binet) is an individually-administered intelligence test that was revised from the original Binet–Simon Scale by Alfred Binet and Theodore Simon. The Stanford–Binet Intelligence Scale is now in its fifth edition (SB5), which was released in 2003. It is a cognitive ability and intelligence test that is used to diagnose developmental or intellectual deficiencies in young children. The test measures five weighted factors and consists of both verbal and nonverbal subtests. The five factors being tested are knowledge, quantitative reasoning, visual-spatial processing, working memory, and fluid reasoning. The development of the Stanford–Binet initiated the modern field of intelligence testing and was one of the first examples of an adaptive test. The test originated in France, then was revised in the United States. It was initially created by the French psychologist Alfred Binet, who, following the introdu ...

Wechsler Adult Intelligence Scale
The Wechsler Adult Intelligence Scale (WAIS) is an IQ test designed to measure intelligence and cognitive ability in adults and older adolescents. The original WAIS (Form I) was published in February 1955 by David Wechsler, as a revision of the Wechsler–Bellevue Intelligence Scale, released in 1939. It is currently in its fourth edition (''WAIS-IV'') released in 2008 by Pearson, and is the most widely used IQ test, for both adults and older adolescents, in the world. History The WAIS is founded on Wechsler's definition of intelligence, which he defined as "... the global capacity of a person to act purposefully, to think rationally, and to deal effectively with his environment." He believed that intelligence was made up of specific elements that could be isolated, defined, and subsequently measured. However, these individual elements were not entirely independent, but were all interrelated. His argument, in other words, is that general intelligence is composed of various speci ...
