Jensen was born August 24, 1923, to a father of Danish ancestry and a mother who was half Polish Jewish and half German (non-Jewish). Events 49 BC - Julius Caesar 's General Gaius Scribonius Curio is defeated in the Second Battle of the Bagradas River Year 1923 ( MCMXXIII) was a Common year starting on Monday (link will display the full calendar of the Gregorian calendar. The history of the Jews in Poland dates back over a Millennium. [5]. Jensen studied at University of California, Berkeley (B.

Columbia University is a private University in the United States and a member of the Ivy League. D. , 1956). Jensen did his doctoral thesis on the Thematic Apperception Test. The Thematic Apperception Test is an example of a Projective test. From 1956 through 1958, Jensen did his postdoctoral research at the University of London, Institute of Psychiatry. The University of London is a university based primarily in London, England, UK. Upon returning to the United States, Jensen became a researcher and professor at the University of California, Berkeley, where he focused on individual differences in learning, especially the influences of culture, development, and genetics on intelligence and learning. Culture (from the Latin cultura stemming from colere, meaning "to cultivate" generally refers to patterns of human activity and the symbolic Jensen received tenure at Berkeley in 1962 and was given his first sabbatical in 1964. Tenure commonly refers to life tenure in a job and specifically to a senior Academic 's Contractual right not to have their position terminated A sabbatical (from the Latin sabbaticus, from the Greek sabbatikos, from Hebrew shabbathon, i He has concentrated much of his work on the learning difficulties of culturally disadvantaged students. In 2003, Jensen was awarded the Kistler Prize for original contributions to the understanding of the connection between the human genome and human society. The Kistler Prize (created 1999 is awarded annually to recognize original contributions "to the understanding of the connection between human heredity and human society" and In classical genetics the genome of a Diploid Organism including Eukarya refers to a full set of chromosomes or genes in a Gamete, thereby A society is a Population of Humans characterized by patterns of relationships between individuals that share a distinctive Culture and Institutions
Jensen has had a life long interest in classical music and was, early in his life, attracted by the idea of becoming a conductor himself. At fourteen, Jensen conducted a band that won a nationwide contest held in San Francisco. Later, Jensen conducted orchestras and attended a seminar given by Nikolai Sokoloff. WikipediaWikiProject Composers#Lead section --> Nikolai Sokoloff ( 28 May 1886 &ndash 25 September Soon after graduating from Berkeley, Jensen moved to New York, mainly to be near the conductor Arturo Toscanini. WikipediaWikiProject Classical music#Biographical_infoboxes --> Arturo Toscanini (ɑrˈturɔ ˌtɔskɑˈnini (March 25 1867 &ndash January Jensen was also deeply interested in the life and example of Gandhi, producing an unpublished book-length manuscript on his life. During Jensen's period in San Diego he spent time working as a social worker with the San Diego Department of Public Welfare. Social work is a discipline involving the application of Social theory and research methods to study and improve the lives of people groups and societies
Jensen's interest in learning differences directed him to the extensive testing of black, Mexican-American, and other minority-group school children. The results led him to distinguish between two separate types of learning ability. Level I, or associative learning, may be defined as retention of input and rote memorization of simple facts and skills. Level II, or conceptual learning, is roughly equivalent to the ability to manipulate and transform inputs, that is, the ability to solve problems. Statistical analysis of his findings led Jensen to conclude that Level I abilities were distributed equally among members of all races, but that Level II occurred with significantly greater frequency among whites and Asian-Americans than among African-Americans and Mexican-Americans.
Later, Jensen was an important advocate in the mainstream acceptance of general intelligence factor, a concept which was essentially synonymous with his Level II conceptual learning. The general intelligence factor (abbreviated g) is a controversial construct used in the field of Psychology ( see also Psychometrics General intelligence factor, or g, is an abstraction that stems from the observation that scores on all forms of cognitive tests correlate positively with one another. Jensen claimed, on the basis of his research, that general cognitive ability is essentially an inherited trait, determined predominantly by genetic factors rather than by environmental conditions. He also contended that while associative learning, or memorizing ability, is equally distributed among the races, conceptual learning, or synthesizing ability, occurs with significantly greater frequency in whites than in blacks. He suggested that from the data, one might conclude that on average, white Americans are more intelligent than African-Americans. African Americans or Black Americans are citizens or residents of the United States who have origins in any of the black populations of Africa [6]
Jensen's most controversial work, published in February 1969 in the Harvard Educational Review, was titled "How Much Can We Boost I. Year 1969 ( MCMLXIX) was a Common year starting on Wednesday (link will display full calendar of the Gregorian calendar. The Harvard Educational Review is an interdisciplinary scholarly journal of opinion and research dealing with education published by the Harvard Education Publishing Group Q. and Scholastic Achievement?" It concluded, among other things, that Head Start programs designed to boost African-American IQ scores had failed, and that this was likely never to be remedied, largely because, in Jensen's estimation, heritability of IQ was over 0. For the Australian television series see Head Start (TV series Head Start is a program of the United States Department of Health and Human African Americans or Black Americans are citizens or residents of the United States who have origins in any of the black populations of Africa An Intelligence Quotient or IQ is a score derived from one of several different Standardized tests attempting to measure Intelligence. 7 of the within-race IQ variability, and the 0. 3 left over was due to non-shared environmental influences.
The work became one of - if not the most - cited papers in the history of psychological testing and intelligence research. [7] The release of Jensen's paper, How Much Can We Boost I. Q. and Scholastic Achievement?, sparked a huge academic controversy. Although his paper was widely cited, a random selection of 60 of these citations revealed that 29 of the papers were direct rebuttals or criticisms of Jensen's arguments, 8 cited the paper as an "example of controversy," 8 used it as a background reference. Only 15 citations of Jensen's paper were in any way supportive of his theories, and 7 of these 15 were only in relation to minor points. [8]
After the paper was released, students and faculty staged large protests outside Jensen's U.C. Berkeley office. The University of California Berkeley (also referred to as Cal, Berkeley and UC Berkeley) is a major research university located in Berkeley There may have been death threats against him. Jensen was denied reprints of his work by his publisher and was not permitted to reply in response to letters of criticism -- both extremely unusual and exceptional policies for their day. Many colleagues at the time felt that even if Jensen's work contained no scientific merit, his treatment was itself against the spirit of science and the free exchange of ideas. In a later article, Jensen argued that his claims had been misunderstood:
Thomas Sowell wrote:
However, Jensen's 1998 The g Factor: The Science of Mental Ability gives his position suggesting a genetic component is implicated in the white-black difference in IQ:
In 1994 he was one of 52 signatories on "Mainstream Science on Intelligence," an editorial written by Linda Gottfredson and published in the Wall Street Journal, which defended the findings on race and intelligence in The Bell Curve. "Mainstream Science on Intelligence" was an opinion piece published in the Wall Street Journal on December 13, 1994.

In 1995 an American Psychological Association task force published a paper titled "Intelligence: Knowns and Unknowns" which concluded that within the white population the heritability of IQ is "around . The American Psychological Association (APA is a professional organization representing psychologists in the U Intelligence Knowns and Unknowns is a report of a Task Force established by the Board of Scientific Affairs of the American Psychological Association. 75" but also "It is sometimes suggested that the Black/White differential in psychometric intelligence is partly due to genetic differences (Jensen, 1972) There is not much direct evidence on this point, but what little there is fails to support the genetic hypothesis. "
Melvin Konner wrote in the notes to his book The Tangled Wing: Biological Constraints on the Human Spirit:
Many studies that purport to be both science-based and attempt to influence public policy have been accused of scientific racism. Konner wrote:
Jensen, 84, and retired, has co-authored recent articles with J. Phillipe Rushton. John Philippe Rushton (born December 3, 1943) is a Psychology professor at the University of Western Ontario, Canada, most widely Konner wrote:
Lisa Suzuki and Joshua Aronson of New York University wrote in 2005 that Jensen has largely ignored evidence that fails to support his position that IQ test score gaps represent a genetic racial hierarchy unwaveringly for over 30 years.

The Pioneer Fund is a US non-profit foundation established in 1937 "to advance the scientific study of heredity and human differences [12]
Paleontologist and evolutionary biologist Stephen Jay Gould, attacked Jensen's work in his 1981 book The Mismeasure of Man. Stephen Jay Gould (September 10 1941 &ndash May 20 2002 was a prominent American paleontologist, evolutionary biologist, and historian of science Year 1981 ( MCMLXXXI) was a Common year starting on Thursday (link displays the 1981 The Mismeasure of Man is a controversial 1981 book written by the Harvard paleontologist Stephen Jay Gould (1941-2002 Gould writes that Jensen misapplies the concept of "heritability", which is defined as a measure of the variation of a trait due to inheritance within a population (Gould 1981: 127; 156-157). In Genetics, Heritability is the proportion of phenotypic variation in a population that is attributable to genetic variation among individuals Jensen uses heritability to measure differences between populations. Gould also disagrees with Jensen's belief that IQ tests measure a real variable, g, or "the general factor common to a large number of cognitive abilities" which can be measured along a unilinear scale. The general intelligence factor (abbreviated g) is a controversial construct used in the field of Psychology ( see also Psychometrics This is a claim most closely identified with Charles Spearman. Charles Edward Spearman, FRS ( September 10 1863 - September 17 1945) was an English Psychologist known for work According to Gould, Jensen misunderstood the research of L. L. Thurstone to ultimately support this claim; Gould however argues that Thurstone's factor analysis of intelligence revealed g to be an illusion (1981: 159; 13-314). Louis Leon Thurstone ( 29 May 1887 &ndash 30 September 1955) was a U Factor analysis is a statistical method used to explain variability among observed Variables in terms of fewer unobserved variables called factors Gould criticizes Jensen's sources including his use of Catharine Cox's 1926 Genetic Studies of Genius, which examines historiometrically the IQs of historic intellectuals after their deaths (Gould 1981: 153-154). Catharine Morris Cox Miles ( May 20, 1890 - October 11, 1984) was an American psychologist known for her work on intelligence Year 1926 ( MCMXXVI) was a Common year starting on Friday (link will display the full calendar of the Gregorian calendar. Historiometry is the historical study of human progress or individual personal characteristics using Statistics to analyze References to famous people
In a 1982 review of The Mismeasure of Man, Jensen gives point-by-point rebuttals to much Gould's critique, including Gould's treatment of heritability, the "reification" of g, and the use of Thurstone's analysis. Year 1982 ( MCMLXXXII) was a Common year starting on Friday (link displays the 1982 Gregorian calendar) Gould's responses appear in the 1996 edition of The Mismeasure of Man.

In Arthur Jensen's response to Gould's criticisms, in the paper titled The Debunking of Scientific Fossils and Straw Persons. [6], Jensen begins his paper with this observation
While Jensen recognizes the validity of some of Gould's claims, in many places, he criticizes Gould's general approach
Jensen adds that Gould made a number of misrepresentations, whether intentional or unintentional, while purporting to present Jensen's own positions

Clocking the Mind : Mental Chronometry and Individual Differences (2006) deals with mental chronometry (MC), and covers a variety of techniques for measuring the speed with which the brain processes information. Mental chronometry is the use of response time in perceptual-motor tasks to infer the content duration and temporal sequencing of cognitive operations Whereas IQ merely represents an ordinal (ranking) scale and thus possesses no true ratio scale properties, Jensen argues mental chronometry represents a true natural science of mental ability.
