Genius is a characteristic of original and exceptional insight in the performance of some art or endeavor that surpasses expectations, sets new standards for the future, establishes better methods of operation, or remains outside the capabilities of competitors. Genius is associated with intellectual ability and creative productivity. The term genius can also be used to refer to people characterised by genius, and/or to polymaths who excel across many subjects.
There is no scientifically precise definition of genius. Howard Gardener identified at least eight distinct categories of intelligences, that are publicly generalized within the one noun 'Genius'. Those categories include linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal, intrapersonal, and naturalistic intelligence. Though many researchers have seen no evidence supporting his proposal for independent brain-based intelligences for different types of cognitive abilities. Experts like Visser argue that the multiple intelligences (MI) hypothesis is wrong and that the general intelligence factor (g) is observable in non-verbal, non-quantitative, and non-paper-and-pencil tasks regardless of whether tasks are timed or untimed. When used to refer to the characteristic, genius is associated with talent, but several authors such as Cesare Lombroso and Arthur Schopenhauer systematically distinguish these terms. Walter Isaacson, biographer of many well-known geniuses, explains that although high intelligence may be a prerequisite, the most common trait that actually defines a genius may be the extraordinary ability to apply creativity and imaginative thinking to almost any situation.
In the early-19th century Carl von Clausewitz, who had a particular interest in what he called "military genius", defined "the essence of Genius" () in terms of "a very high mental capacity for certain employments".
Etymology
In ancient Rome, the genius (plural in Latin genii) was the guiding spirit or tutelary deity of a person, family (gens), or place (genius loci).genius. (n.d.). Dictionary.com Unabridged (v 1.1). Retrieved May 17, 2008, from Dictionary.com website: http://dictionary.reference.com/browse/genius Connotations of the word in Latin have a lineal relationship with the Greek word daemon in classical and medieval texts, and also share a relationship with the Arabic word al-ghul (as in the star Algol; its literal meaning being "the Demon").
The noun is related to the Latin verbs "gignere" (to beget, to give birth to) and "generare" (to beget, to generate, to procreate), and derives directly from the Indo-European stem thereof: "ǵenh" (to produce, to beget, to give birth). Because the achievements of exceptional individuals seemed to indicate the presence of a particularly powerful genius, by the time of Augustus, the word began to acquire its secondary meaning of "inspiration, talent".Oxford Latin Dictionary (Oxford: Clarendon Press, 1982, 1985 reprinting), entries on genius, p. 759, and gigno, p. 764. The term genius acquired its modern sense in the eighteenth century, and is a conflation of two Latin terms: genius, as above, and Ingenium, a related noun referring to our innate dispositions, talents, and inborn nature. Beginning to blend the concepts of the divine and the talented, the Encyclopédie article on genius (génie) describes such a person as "he whose soul is more expansive and struck by the feelings of all others; interested by all that is in nature never to receive an idea unless it evokes a feeling; everything excites him and on which nothing is lost."Saint-Lambert, Jean-François de (ascribed).

Historical development
Galton
The assessment of intelligence was initiated by Francis Galton (1822–1911) and James McKeen Cattell. They had advocated the analysis of reaction time and sensory acuity as measures of "neurophysiological efficiency" and the analysis of sensory acuity as a measure of intelligence.
Galton is regarded as the founder of psychometry. He studied the work of his older half-cousin Charles Darwin about biological evolution. Hypothesizing that eminence is inherited from ancestors, Galton did a study of families of eminent people in Britain, publishing it in 1869 as Hereditary Genius. Galton's ideas were elaborated from the work of two early 19th-century pioneers in statistics: Carl Friedrich Gauss and Adolphe Quetelet. Gauss discovered the normal distribution (bell-shaped curve): given a large number of measurements of the same variable under the same conditions, they vary at random from a most frequent value, the "average", to two least frequent values at maximum differences greater and lower than the most frequent value. Quetelet discovered that the bell-shaped curve applied to social statistics gathered by the French government in the course of its normal processes on large numbers of people passing through the courts and the military. His initial work in criminology led him to observe "the greater the number of individuals observed the more do peculiarities become effaced...". This ideal from which the peculiarities were effaced became "the average man".
Galton was inspired by Quetelet to define the average man as "an entire normal scheme"; that is, if one combines the normal curves of every measurable human characteristic, one will, in theory, perceive a syndrome straddled by "the average man" and flanked by persons that are different. In contrast to Quetelet, Galton's average man was not statistical but was theoretical only. There was no measure of general averageness, only a large number of very specific averages. Setting out to discover a general measure of the average, Galton looked at educational statistics and found bell-curves in test results of all sorts; initially in mathematics grades for the final honors examination and in entrance examination scores for Sandhurst.
Galton's method in Hereditary Genius was to count and assess the eminent relatives of eminent men. He found that the number of eminent relatives was greater with a closer degree of kinship. This work is considered the first example of historiometry, an analytical study of historical human progress. The work is controversial and has been criticized for several reasons. Galton then departed from Gauss in a way that became crucial to the history of the 20th century AD. The bell-shaped curve was not random, he concluded. The differences between the average and the upper end were due to a non-random factor, "natural ability", which he defined as "those qualities of intellect and disposition, which urge and qualify men to perform acts that lead to reputation…a nature which, when left to itself, will, urged by an inherent stimulus, climb the path that leads to eminence."Bernstein (1998), page 163. The apparent randomness of the scores was due to the randomness of this natural ability in the population as a whole, in theory.
Criticisms include that Galton's study fails to account for the impact of social status and the associated availability of resources in the form of economic inheritance, meaning that inherited "eminence" or "genius" can be gained through the enriched environment provided by wealthy families. Galton went on to develop the field of eugenics. Galton attempted to control for economic inheritance by comparing the adopted nephews of popes, who would have the advantage of wealth without being as closely related to popes as sons are to their fathers, to the biological children of eminent individuals.
Psychology
Genius is expressed in a variety of forms (e.g., mathematical, literary, musical performance). Persons with genius tend to have strong intuitions about their domains, and they build on these insights with tremendous energy. Carl Rogers, a founder of the humanistic approach to psychology, expands on the idea of a genius trusting his or her intuition in a given field, writing: "El Greco, for example, must have realized as he looked at some of his early work, that 'good artists do not paint like that.' But somehow he trusted his own experiencing of life, the process of himself, sufficiently that he could go on expressing his own unique perceptions. It was as though he could say, 'Good artists don't paint like this, but I paint like this.' Or to move to another field, Ernest Hemingway was surely aware that 'good writers do not write like this.' But fortunately he moved toward being Hemingway, being himself, rather than toward someone else's conception of a good writer."
It has been suggested that there exists a connection between mental illness, in particular schizophrenia and bipolar disorder, and genius.Efroimson, V. P. The Genetics of Genius. 2002 Individuals with bipolar disorder and schizotypal personality disorder, the latter of which being more common amongst relatives of schizophrenics, tend to show elevated creativity.. Several people who have been regarded as geniuses were diagnosed with mental disorders; examples include Vincent van Gogh, Virginia Woolf, John Forbes Nash Jr. and Ernest Hemingway.Ernest Hemingway
In a 2010 study conducted by the Karolinska Institute, it was observed that highly creative individuals and schizophrenics have a lower density of thalamic dopamine D2 receptors. One of the investigators explained that "Fewer D2 receptors in the thalamus probably means a lower degree of signal filtering, and thus a higher flow of information from the thalamus." This could be a possible mechanism behind the ability of healthy highly creative people to see numerous uncommon connections in a problem-solving situation and the bizarre associations found in schizophrenics.
IQ and genius
Galton was a pioneer in investigating both eminent human achievement and mental testing. In his book Hereditary Genius, written before the development of IQ testing, he proposed that hereditary influences on eminent achievement are strong, and that eminence is rare in the general population. Lewis Terman chose "'near' genius or genius" as the classification label for the highest classification on his 1916 version of the Stanford–Binet test. By 1926, Terman began publishing about a longitudinal study of California schoolchildren who were referred for IQ testing by their schoolteachers, called Genetic Studies of Genius, which he conducted for the rest of his life. Catherine M. Cox, a colleague of Terman's, wrote a whole book, The Early Mental Traits of 300 Geniuses, published as volume 2 of The Genetic Studies of Genius book series, in which she analyzed biographical data about historic geniuses. Although her estimates of childhood IQ scores of historical figures who never took IQ tests have been criticized on methodological grounds, Cox's study was thorough in finding out what else matters besides IQ in becoming a genius. By the 1937 second revision of the Stanford–Binet test, Terman no longer used the term "genius" as an IQ classification, nor has any subsequent IQ test. In 1939, David Wechsler specifically commented that "we are rather hesitant about calling a person a genius on the basis of a single intelligence test score".
