Intelligence Testing from 1800 to 1900
A. Scientific Study of Individual Differences
The first scientific attempt of learning the mind were the studies of Francis Galton and James Cattell. * Francis Galton
He was a cousin of Douglas Strutt Galton, cousin of Charles Darwin and was an English Victorian polymath:anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, psychometrician, and statistician. He was knighted in 1909. Galton had a prolific intellect, and produced over 340 papers and books. He also created the Statistical Concept of Correlation and widely promoted regression toward the mean. He was the first to apply statistical methods to the study of human differences and inheritance of intelligence, and introduced the use of questionnaires and surveys for collecting data on human communities, which he needed for genealogical and biographical works and for his anthropometric studies. He was a pioneer in eugenics, coining the term itself and the phrase "nature versus nurture". His book, Hereditary Genius (1869), was the first social scientific attempt to study genius and greatness. As an investigator of the human mind, he founded psychometrics (the science of measuring mental faculties) and differential psychology and the lexical hypothesis of personality. He devised a method for classifying fingerprints that proved useful in forensic science. He also conducted research on the power of prayer, concluding it had none by its null effects on the longevity of those prayed for. * James McKeen Cattell

 (May 25, 1860 - January 20, 1944), American psychologist, was the first professor of psychology in the United States at theUniversity of Pennsylvania and long-time editor and publisher of scientific journals and publications, most notably the journal Science. He also served on the board of trustees for Science Service, now known as Society for Science & the Public, from 1921-1944. At the beginning of his career, many scientists regarded psychology at best a minor field of study, or at worst a pseudoscience such as phrenology. Perhaps more than any of his contemporaries, Cattell helped establish psychology as a legitimate science, worthy of study at the highest levels of the academy. At the time of his death, the New York Times hailed him as "the dean of American science." Yet Cattell may be best remembered for his uncompromising opposition to American involvement in World War I. His public opposition to the draft led to his dismissal from his position at Columbia University, a move that later led many American universities to establish tenure as a means of protecting unpopular beliefs. B. Foundations of Statistical Methods

Galton’s contribution to educational measurement is his findings of statistical methods. He invented and made derivations of the statistical methods and experimental techniques which influenced the mental and educational tests. He originated the questionnaire method and Theory of Eugenics. EUGENICS is the science which deals with all influences that improve the inborn qualities of a race; also with those that develop them to the utmost advantage. 1. Dissemination of a knowledge of the laws of heredity, so far as they are surely known, and promotion of their further study. Few seem to be aware how greatly the knowledge of what may be termed the actuarial side of heredity has advanced in recent years. The average closeness of kinship in each degree now admits of exact definition and of being treated mathematically, like birth- and death-rates, and the other topics with which actuaries are concerned. 2. Historical inquiry into the rates with which the various classes of society (classified according to civic usefulness.) have contributed to the population at various times, in ancient and modern nations. There is strong reason for believing that national rise and decline is closely connected with this influence. It seems to be the tendency...
