A genius is a person who displays exceptional intellectual ability, creative productivity, universality in genres or originality, typically to a degree that is associated with the achievement of new advances in a domain of knowledge. Despite the presence of scholars in many subjects throughout history, many geniuses have shown high achievements in only a single kind of activity.
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.
Mensa is the largest and oldest high IQ society in the world. It is a non-profit organization open to people who score at the 98th percentile or higher on a standardised, supervised IQ or other approved intelligence test. Mensa formally comprises national groups and the umbrella organisation Mensa International, with a registered office in Caythorpe, Lincolnshire, England, which is separate from the British Mensa office in Wolverhampton. The word mensa is Latin for 'table', as is symbolised in the organisation's logo, and was chosen to demonstrate the round-table nature of the organisation; the coming together of equals.
The Stanford–Binet Intelligence Scales is an individually administered intelligence test that was revised from the original Binet–Simon Scale by Lewis Terman, a psychologist at Stanford University. The Stanford–Binet Intelligence Scale is now in its fifth edition (SB5) and 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.
Intellectual giftedness is an intellectual ability significantly higher than average. It is a characteristic of children, variously defined, that motivates differences in school programming. It is thought to persist as a trait into adult life, with various consequences studied in longitudinal studies of giftedness over the last century. There is no generally agreed definition of giftedness for either children or adults, but most school placement decisions and most longitudinal studies over the course of individual lives have followed people with IQs in the top 2.5 percent of the population—that is, IQs above 130. Definitions of giftedness also vary across cultures.
Intelligence has been defined in many ways: the capacity for logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. More generally, it can be described as the ability to perceive or infer information, and to retain it as knowledge to be applied towards adaptive behaviors within an environment or context.

The Prometheus Society is a high IQ society, similar to Mensa International, but much more restrictive. The entry test 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.
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 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. Data collection for the next version began in 2016 and is expected to end in spring 2020.
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 Triple Nine Society is a non-profit, 501(c)(7) organization incorporated in Virginia, USA. The organization was founded in 1978. As of February 2020, TNS reports a member base of over 1,900 adults residing in 50 countries. The Society's constitution encourages friendship, communication, and intellectual exploration. TNS members communicate online, at gatherings, and through Vidya, the Society's bimonthly journal. Dues are set at $10 per year for the internet version of Vidya and $30 per year for the print version..
Lewis Madison Terman was an American psychologist and author. He was noted as a pioneer in educational psychology in the early 20th century at the Stanford Graduate School of Education. He is best known for his revision of the Stanford–Binet Intelligence Scales and for initiating the longitudinal study of children with high IQs called the Genetic Studies of Genius. He was a prominent eugenicist and was a member of the Human Betterment Foundation. He also served as president of the American Psychological Association. A Review of General Psychology survey, published in 2002, ranked Terman as the 72nd most cited psychologist of the 20th century, in a tie with G. Stanley Hall.
Cognitive tests are assessments of the cognitive capabilities of humans and other animals. Tests administered to humans include various forms of IQ tests; those administered to animals include the mirror test and the T maze test. Such study is important to research concerning the philosophy of mind and psychology, as well as determination of human and animal intelligence.
Raven's Progressive Matrices or RPM is a nonverbal group test typically used in educational settings. It is usually a 60-item test used in measuring abstract reasoning and regarded as a non-verbal estimate of fluid intelligence. It is the most common and popular test administered to groups ranging from 5-year-olds to the elderly. It is made of 60 multiple choice questions, listed in order of difficulty. This format is designed to measure the test taker's reasoning ability, the eductive ("meaning-making") component of Spearman's g. The tests were originally developed by John C. Raven in 1936. In each test item, the subject is asked to identify the missing element that completes a pattern. Many patterns are presented in the form of a 6×6, 4×4, 3×3, or 2×2 matrix, giving the test its name.
The Culture Fair Intelligence Test (CFIT) was created by Raymond Cattell in 1949 as an attempt to measure cognitive abilities devoid of sociocultural and environmental influences. Scholars have subsequently concluded that the attempt to construct measures of cognitive abilities devoid of the influences of experiential and cultural conditioning is a challenging one. Cattell proposed that general intelligence (g) comprises both Fluid Intelligence (Gf) and Crystallized Intelligence (Gc). Whereas Gf is biologically and constitutionally based, Gc is the actual level of a person's cognitive functioning, based on the augmentation of Gf through sociocultural and experiential learning.
In statistics, a floor effect arises when a data-gathering instrument has a lower limit to the data values it can reliably specify. This lower limit is known as the "floor". Floor effects are occasionally encountered in psychological testing, when a test designed to estimate some psychological trait has a minimum standard score that may not distinguish some test-takers who differ in their responses on the test item content. Giving preschool children an IQ test designed for adults would likely show many of the test-takers with scores near the lowest standard score for adult test-takers. To indicate differences in current intellectual functioning among young children, IQ tests specifically for young children are developed, on which many test-takers can score well above the floor score. An IQ test designed to help assess intellectually disabled persons might intentionally be designed with easier item content and a lower floor score to better distinguish among individuals taking the test as part of an assessment process.
Founded in 1982 by Ronald K. Hoeflin to facilitate psychometric research, 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.
IQ classification is the practice by IQ test publishers of labeling IQ score ranges with category names such as "superior" or "average".
The Cognitive Abilities Test(CogAT) is a group-administered K–12 assessment intended to estimate students' learned reasoning and problem solving abilities through a battery of verbal, quantitative, and nonverbal test items. The test purports to assess students' acquired reasoning abilities while also predicting achievement scores when administered with the co-normed Iowa Tests. The test was originally published in 1954 as the Lorge-Thorndike Intelligence Test, after the psychologists who authored the first version of it, Irving Lorge and R.L. Thorndike.
The Genetic Studies of Genius, today known as the Terman Study of the Gifted, is currently the oldest and longest-running longitudinal study in the field of psychology. It was begun by Lewis Terman at Stanford University in 1921 to examine the development and characteristics of gifted children into adulthood.
