Arthur Robert Jensen (August 24, 1923 – October 22, 2012) was an American psychologist and author. He was a professor of educational psychology at the University of California, Berkeley. Jensen was known for his work in psychometrics and differential psychology, the study of how and why individuals differ behaviorally from one another.
He was a major proponent of the hereditarian position in the nature and nurture debate, the position that genetics play a significant role in behavioral traits, such as intelligence and personality. He was the author of over 400 scientific papers published in refereed journals and sat on the editorial boards of the scientific journals Intelligence and Personality and Individual Differences.
He was rated as one of the 50 most eminent psychologists of the 20th century. He was also a controversial figure, largely for his conclusions regarding the causes of race-based differences in intelligence.

Jensen was born August 24, 1923, in San Diego, California, the son of Linda Mary (née Schachtmayer) and Arthur Alfred Jensen, who operated and owned a lumber and building materials company. His paternal grandparents were Danish immigrants and his mother was of half Polish Jewish and half German descent. He studied at University of California, Berkeley (B.A. 1945), San Diego State College (M.A., 1952) and Columbia University (Ph.D., 1956), and did his doctoral thesis with Percival Symonds on the Thematic Apperception Test. From 1956 through 1958, he did postdoctoral research at the University of London, Institute of Psychiatry with Hans Eysenck.
Upon returning to the United States, he 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. He received tenure at Berkeley in 1962 and was given his first sabbatical in 1964. He concentrated much of his work on the learning difficulties of culturally disadvantaged students.
Jensen had a lifelong interest in classical music and was, early in his life, attracted by the idea of becoming a conductor himself. At 14, he conducted a band that won a nationwide contest held in San Francisco. Later, he conducted orchestras and attended a seminar given by Nikolai Sokoloff. Soon after graduating from Berkeley, he moved to New York, mainly to be near the conductor Arturo Toscanini. He 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.
IQ and academic achievement
Jensen's interest in learning differences directed him to the extensive testing of 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.
Later, Jensen was an important advocate in the mainstream acceptance of the general factor of intelligence, a concept which was essentially synonymous with his Level II conceptual learning. The general 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 non-whites.
Jensen's most controversial work, published in February 1969 in the Harvard Educational Review, was titled "How Much Can We Boost IQ 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, 80% of the variance in IQ in the population studied was the result of genetic factors and the remainder was due to environmental influences.
The work became one of the most cited papers in the history of psychological testing and intelligence research, although a large number of citations consisted of rebuttals of Jensen's work, or references to it as an example of a controversial paper.
After the paper was released, large protests were held, demanding that Jensen be fired. Jensen's car tires were slashed, the university police provided him with plain-clothes bodyguards, and he and his family received threats that were considered so realistic by the police that they temporarily left their house. Jensen was spat on and was prevented from delivering lectures by disruptive protests. The editorial board of the Harvard Educational Review for a time refused to let him have reprints of his article, and said that they had not solicited the section on racial differences; Jensen later provided correspondence in which the board had requested he do so.
In a later article, Jensen argued that his claims had been misunderstood:
...nowhere have I "claimed" an "innate deficiency" of intelligence in blacks. My position on this question is clearly spelled out in my most recent book: "The plain fact is that at present there exists no scientifically satisfactory explanation for the differences between the IQ distributions in the black and white populations. The only genuine consensus among well-informed scientists on this topic is that the cause of the difference remains an open question." (Jensen, 1981a, p. 213).
Professor Jensen pointed out back in 1969 that black children's IQ scores rose by 8 to 10 points after he met with them informally in a play room and then tested them again after they were more relaxed around him. He did this because "I felt these children were really brighter than their IQ would indicate." What a shame that others seem to have less confidence in black children than Professor Jensen has had.
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 Chapter 12: Population Differences in g: Causal Hypotheses, Jensen writes:
The relationship of the g factor to a number of biological variables and its relationship to the size of the white-black differences on various cognitive tests (i.e., Spearman's hypothesis) suggests that the average white-black difference in g has a biological component. Human races are viewed not as discrete, or Platonic, categories, but rather as breeding populations that, as a result of natural selection, have come to differ statistically in the relative frequencies of many polymorphic genes. The genetic distances between various populations form a continuous variable that can be measured in terms of differences in gene frequencies. Racial populations differ in many genetic characteristics, some of which, such as brain size, have behavioral and psychometric correlates, particularly g.
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 declared the consensus of the signing scholars on the meaning and significance of IQ following the publication of the book The Bell Curve. Jensen received $1.1 million from the Pioneer Fund, an organization frequently described as racist and white supremacist in nature. The fund contributed a total of $3.5 million to researchers cited in The Bell Curve's most controversial chapter "that suggests some races are naturally smarter than others" with Jensen's works being cited twenty-three times in the book's bibliography.
In 2005, Jensen's article, co-written with J. Philippe Rushton, named "Thirty Years of Research on Race Differences in Cognitive Ability", was published in the APA journal Psychology, Public Policy and Law. Jensen and Rushton present ten categories of evidence in support of the notion that IQ differences between whites and blacks are partly genetic in origin.
Melvin Konner of Emory University, wrote:
Statements made by Arthur Jensen, William Shockley, and other investigators in the late 1960s and early 1970s about race and IQ or social class and IQ rapidly passed into currency in policy discussions. Many of these statements were proved wrong, but they had already influenced some policymakers, and that influence is very difficult to recant.
Paul E. Meehl of the University of Minnesota, after being honored by the APA, wrote that Jensen's "contributions, in both quality and quantity, certainly excelled mine" and that he was "embarrassed" and "distress[ed]" that APA refused to honor Jensen out of ideology.
Sandra Scarr of Yale University wrote that Jensen possessed an "uncompromising personal integrity" and set the standard for "honest psychological science". She contrasted him and his work favorably to some of his critics, who she called "politically driven liars, who distort scientific facts in a misguided and condescending effort to protect an impossible myth about human equality".
Lisa Suzuki and Joshua Aronson of New York University wrote that Jensen had largely ignored evidence which failed to support his position that IQ test score gaps represent genetic racial differences.
After Jensen's death, James Flynn of the University of Otago, a prominent advocate of the environmental position, told The New York Times that Jensen was without racial bias and had not initially foreseen that his research would be used to argue for racial supremacy and that his career was "emblematic of the extent to which American scholarship is inhibited by political orthodoxy", though he noted that Jensen shifted towards genetic explanations later in life.
Francis Crick, the co-discoverer of DNA, considered that there was "much substance to Jensen's arguments" and that it was "likely that more than half the difference between the average I.Q. of American whites and Negroes is due to genetic reasons, and will not be eliminated by any foreseeable change in the environment."
Paleontologist and evolutionary biologist Stephen Jay Gould criticized Jensen's work in his 1981 book The Mismeasure of Man. 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). According to Gould, 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.
This is a claim most closely identified with Charles Spearman. 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). 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).
In 1980 Jensen published a detailed book in defense of the tests used to measure mental abilities, entitled Bias in Mental Testing. Reviewing this book, psychologist Kenneth Kaye endorsed Jensen's distinction between bias and discrimination, saying that he found many of Jensen's opponents to be more politically-biased than Jensen was.
Jensen's response and criticism
In Arthur Jensen's response to Gould's criticisms, in the paper titled The Debunking of Scientific Fossils and Straw Persons, Jensen begins his paper with this observation:
Stephen Jay Gould is a paleontologist at Harvard's Museum of Comparative Zoology and offers a course at Harvard entitled, "Biology as a Social Weapon." Apparently the course covers much the same content as does the present book. Having had some personal cause for interest in ideologically motivated attacks on biologically oriented behavioral scientists, I first took notice of Gould when he played a prominent role in a group called Science for the People and in that group's attack on the theories of Harvard zoologist Edward O. Wilson, a leader in the development of sociobiology...
While Jensen recognizes the validity of some of Gould's claims, in many places, he criticizes Gould's general approach:
This charge of a social, value-laden science undoubtedly contains an element of truth. In recent years, however, we recognize this charge as the keystone of the Marxist interpretation of the history of science.
Jensen adds that Gould made a number of misrepresentations, whether intentional or unintentional, while purporting to present Jensen's own positions:
In his references to my own work, Gould includes at least nine citations that involve more than just an expression of Gould's opinion; in these citations Gould purportedly paraphrases my views. Yet in eight of the nine cases, Gould's representation of these views is false, misleading, or grossly caricatured. Nonspecialists could have no way of knowing any of this without reading the cited sources. While an author can occasionally make an inadvertent mistake in paraphrasing another, it appears Gould's paraphrases are consistently slanted to serve his own message.
Jensen expressed considerably greater praise of his frequent intellectual sparring partner, James R. Flynn:
Now and then I am asked by colleagues, students, and journalists: who, in my opinion, are the most respectable critics of my position on the race-IQ issue? The name James R. Flynn is by far the first that comes to mind. His book, Race, IQ and Jensen (1980), is a distinguished contribution to the literature on this topic, and, among the critiques I have seen of my position, is virtually in a class by itself for objectivity, thoroughness, and scholarly integrity.
Bias in Mental Testing
Bias in Mental Testing (1980) is a book examining the question of test bias in commonly used standardized tests. The book runs almost 800 pages and has been called "exhaustive" by three researchers who reviewed the field 19 years after the book's publication. It reviewed in detail the available evidence about test bias across major US racial/ethnic groups. Jensen concluded that "the currently most widely used standardized tests of mental ability -- IQ, scholastic aptitude, and achievement tests -- are, by and large, not biased against any of the native-born English-speaking minority groups on which the amount of research evidence is sufficient for an objective determination of bias, if the tests were in fact biased. For most nonverbal standardized tests, this generalization is not limited to English-speaking minorities." (p. ix). Jensen also published a summary of the book the same year which was a target article in the journal Behavioral and Brain Sciences to which 27 commentaries were printed along with the author's reply.
The g Factor
The g Factor: The Science of Mental Ability (1998) is a book on the general intelligence factor (g). The book deals with the intellectual history of g and various models of how to conceptualize intelligence, and with the biological correlates of g, its heritability, and its practical predictive power.
Clocking the Mind
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. Whereas IQ merely represents an interval (ranking) scale and thus possesses no true ratio scale properties, Jensen argues mental chronometry represents a true natural science of mental ability.
In 2003, Jensen was awarded the Kistler Prize for original contributions to the understanding of the connection between the human genome and human society. In 2006, the International Society for Intelligence Research awarded Jensen its Lifetime Achievement Award.

Since his death in 1972, Draper and the Pioneer Fund have been criticized for funding "race and intelligence research," which is a euphemism for "scientific" racism (Kenny 2002, Tucker 2002). Draper has become even more controversial since the publication of The Bell Curve (Herrnstein & Murray 1994), which purported to prove that white people's intelligence was superior to black people's intelligence, because the Pioneer Fund supported the controversial research in the book (Fraser 1995; Jacoby & Glauberman 1995; Baum 2004).

According to Taxpayers the Pioneer Fund in its first charter had called for the encouragement of the "reproduction of individuals descended predominantly from white persons who settled in the original 13 states or from related stock." Taxpayers also claimed that the fund supported racist research, including that of notorious scientist William B. Shockley. In a press release, "taxpayers described the Pioneer Fund as a "white supremacist" organization. What was the racist link between Prop. 187 and the Pioneer Fund? Taxpayers claimed that the Federation for American Immigration Reform (FAIR) had received S600,000 in grants since 1988 from the Pioneer Fund, and that Alan Nelson was FAIR's lobbyist in Sacramento when he coauthored Prop. 187.

Ideology: White Nationalist. Started in 1937 by textile magnate Wickliffe Draper, the Pioneer Fund's original mandate was to pursue "race betterment" by promoting the genetic stock of those "deemed to be descended predominantly from white persons who settled in the original thirteen states prior to the adoption of the Constitution." Today, it still funds studies of race and intelligence, as well as eugenics, the "science" of breeding superior human beings that was discredited by various Nazi atrocities. The Pioneer Fund has supported many of the leading Anglo-American race scientists of the last several decades as well as anti-immigration groups such as the Federation for American Immigration Reform (FAIR).
