Since the publication of Francis Galton's Hereditary Genius in 1869, and especially with the accelerated development of intelligence tests in the early 1900s, there has been a vast amount of social scientific research published relative to the question of greatness.
The earliest such research, Hereditary Genius, by Francis Galton (1869), argued that people vary hugely in "natural ability" which is allegedly inherited biologically.
To prove this thesis Galton collected data showing that genius clusters in what he termed "Notable Family Lines", such as those of Bernoulli, Cassini, Darwin, Herschel, and Jussieu in science, or Bach in music.
For example, da Vinci, Michelangelo, Descartes, Benjamin Franklin, Goethe, and others with IQs in the mid 160s or above were superior in their versatility to those attaining lower scores, such as George Washington, Palestrina, or Philip Sheridan.
[10] The work of both Cox and Galton has been criticized for failing to take sufficient account of the role of nurture, or more specifically socio-economic and educational advantage, in the achievements of these historical greats.
Then within these groupings he listed his notables in "strict chronological order", identifying the most eminent figures by using capital letters for their surnames (e.g. EMERSON, LONGFELLOW, POE, WHITMAN, etc.
[16] Recent research is consistent with these explanations;[17] but many aspects of the developmental process from birth to the attainment of greatness remain unaccounted for by Kroeber's anthropological approach.
[18] Retrospective studies, involving extensive interviews with individuals who have attained eminence, or at least exceptional levels of achievement, have added much to our understanding of the developmental process.
[20] She also interviewed forty-one Nobel laureates extensively about their "apprenticeships" to "master" scientists while they were doing their doctoral research, and other aspects of their career development related to the above topics.
[29] In particular Eysenck is interested in a personality trait called "psychoticism ... chief among (whose) cognitive features is a tendency to over-inclusiveness, i.e., an inclination not to limit one's associations to relevant ideas, memories, images, etc.
"[30] He considers a massive range of experimental psychological research in order to establish the underlying genetic, neuro-chemical mechanisms which may be operating to influence levels of creativity associated with fluctuations in "the tendency towards over-inclusiveness indicative of psychoticism..."[31] Eysenck's assessment of his overall argument is as follows: "There is no hint that the theory is more than a suggestion of how many disparate facts and hypotheses can be pulled together into a causal chain, explaining... the apogee of human endeavour – genius.
[33] Dorris argues that those who attain 'greatness' are credited with solving a key generational problem in a field and/or society (e.g., Albert Einstein resolving the conflict between Isaac Newton and James Clerk Maxwell in physics at the outset of the 20th century; or Woody Guthrie providing a voice for the outcasts of the Great Depression of the 1930s).
[39] Dorris documents his theoretical arguments with extensive case studies of a wide range of individuals, including Einstein, Elvis, Monet, Mozart, da Vinci, Abraham Lincoln, Watson and Crick, basketball great Bill Russell, Louis Armstrong, Bill Gates, Alfred Hitchcock, Woody Guthrie, and Norma Jeane/Marilyn Monroe.
