Raymond Bernard Cattell (20 March 1905 – 2 February 1998) was a British and American psychologist, known for his exploration of many areas in psychology. These areas included: the basic dimensions of personality and temperament, a range of cognitive abilities, the dynamic dimensions of motivation and emotion, the clinical dimensions of personality, patterns of group and social behavior, applications of personality research to psychotherapy and learning theory, predictors of creativity and achievement, and many scientific research methods for exploring and measuring these areas. Cattell was famously productive throughout his 92 years, authoring and co-authoring over 50 books and 500 articles, and over 30 standardized tests. According to a widely cited ranking, he was the 16th most influential and eminent psychologist of the 20th century.
As a psychologist, Cattell was rigorously devoted to the scientific method. He was an early proponent of using factor analytical methods instead of what he called "verbal theorizing" to explore the basic dimensions of personality, motivation, and cognitive abilities. One of the most important results of Cattell's application of factor analysis was his discovery of 16 factors underlying human personality. He called these factors "source traits" because he believed they provide the underlying source for the surface behaviors we think of as personality. This theory of personality factors and the instrument used to measure them are known respectively as the 16 personality factor model and the 16PF Questionnaire.
Although Cattell is best known for identifying the dimensions of personality, he also studied basic dimensions of other domains: intelligence, motivation, and vocational interests. Cattell theorized the existence of fluid and crystallized intelligences to explain human cognitive ability, and authored the Culture Fair Intelligence Test to minimize the bias of written language and cultural background in intelligence testing.

Innovations and accomplishments
Cattell's principal accomplishments were in personality, intelligence, and statistics. In personality, he is best remembered for his 16-factor model of personality, arguing for this over Eysenck's simpler 3-factor model, and developing tests to measure his primary factors in the form of the 16PF Questionnaire. He was the first to propose a hierarchical, multi-level model of personality with basic primary factors at the first level and the broader, "second-order," or global traits of personality at a higher level of personality organization (Cattell, 1943). These five global traits are now identified with the widely used Big Five model of personality. His research led to further advances, such as distinguishing between state and trait measurement of personality. He also distinguished between immediate, transitory states and long-term, enduring tendencies for traits such as anxiety.
In intelligence, Cattell is known for the distinction of fluid and crystallized intelligence. He distinguished between current, abstract, adaptive intellectual abilities that he called "fluid intelligence" and applied knowledge that he called "crystallized intelligence." As a foundation for this distinction, Cattell developed the investment-model of ability, arguing that crystallized ability emerged from the investment of fluid ability in a particular topic of knowledge. He contributed to cognitive epidemiology with his theory that crystallized knowledge, while initially lacking fluid ability, could be maintained or even increase after fluid ability begins to decline, a concept used in the National Adult Reading Test (NART). Cattell developed his own ability test, the Culture Fair Intelligence Scales, which was designed to provide a completely non-verbal measure of intelligence like that now seen in the Raven's. The Culture Fair Intelligence Scales were also intended to minimize the influence of cultural or educational background on the results of intelligence tests.
In statistics, he founded the Society of Multivariate Experimental Psychology (1960) and its journal Multivariate Behavioral Research. He was an early and frequent user of factor analysis. Catell further developed factor analysis by inventing the Scree Test, which used the curve of latent roots to judge the best number of factors to result from a factor analysis. He also developed a new factor analysis rotation, the "Procrustes" rotation, which was designed to test the fit of data to a prior-hypothesized factor structure. Additional contributions include the Coefficient of Profile Similarity (taking account of shape, scatter, and level of two score profiles); the Dynamic Calculus for assessing interests and motivation; P-technique factor analysis for an occasion-by-variable matrix; the Taxonome program for ascertaining the number and contents of clusters in a data set; the Basic Data Relations Box (assessing the dimensions of experimental designs); sampling of variables, as opposed to or in conjunction with sampling of persons; the group syntality construct, or the "personality" of a group; factoring or repeated measures on single individuals to study fluctuating personality states; and Multiple Abstract Variance Analysis (MAVA), with "specification equations" to embody genetic and environmental variables and their interactions.
Raymond Cattell was born on 20 March 1905, in Hilltop, West Bromwich, a small town in England near Birmingham, where his father's family was involved in inventing new parts for engines, automobiles, and other machines. It was a time when the burgeoning scientific ideas influenced his perspective on how to make a difference in the world. He wrote: "1905 was a felicitous year in which to be born. The airplane was just a year old. The Curies and Rutherford in that year penetrated the heart of the atom and the mystery of its radiations, Binet launched the first intelligence test, and Einstein, the theory of relativity."
When Cattell was about 5 years old, his family moved to Torquay, Devon, in the south of England, where he grew up with strong interests in science and spent a lot of time sailing around the coastline. He was the first of his family (and the only one in his generation) to attend university: in 1921, he was awarded a scholarship to study chemistry at the University of London, where he obtained a Bachelor of Science at the age of 19. While studying physics and chemistry at university he learned from influential people in many other fields, who visited or lived in London. He writes: "[I] browsed far outside science in my reading and attended public lectures - Bertrand Russell, H. G. Wells, Huxley, and Shaw being my favorite speakers (the last, in a meeting at King's College, converted me to vegetarianism - for almost two years!)."
As he observed first-hand the terrible destruction and suffering after World War I, he was increasingly attracted to the idea of applying the tools of science to the serious human problems that he saw around him. He stated that in the cultural upheaval after WWI, he felt that his laboratory table had begun to seem too small and the world's problems so vast. Thus, he decided to change his field of study and pursue a Ph.D in psychology at the University College, London, which he received in 1929.
While working on his Ph.D., Cattell accepted a position teaching and counseling in the Department of Education at Exeter University. He ultimately found this disappointing because there were no resources to conduct research there. During his three years at Exeter, Cattell courted and married Monica Rogers, whom he had known since his boyhood in Devon and they had a son together. Soon afterward he moved to Leicester where he organized one of England's first child guidance clinics. It was also in this time period that he finished his first book "Under Sail Through Red Devon," which described his many adventures sailing around the coastline and estuaries of South Devon and Dartmoor.
In 1937, he reluctantly left England and moved to the United States, when he was invited by Edward Thorndike, to come to Columbia University. Then, when the G. Stanley Hall professorship in Psychology became available at Clark University in 1938, Cattell was recommended by Thorndike and was appointed to the position at the age of 34.
After a few productive years at Clark, he was invited by Gordon Allport to join the Harvard University faculty in 1941. While at Harvard he planned and began some of the research in personality that would become the foundation for much of his later work in this area.
During World War II, Cattell served as a civilian consultant to the U.S. government researching and developing tests for selecting officers in the armed forces. With the war coming to an end, Cattell returned to teaching at Harvard and married Alberta Karen Schuettler, a Ph.D. student in mathematics at Radcliffe College. Over the years, she worked with Cattell on many aspects of his research, writing, and test development. They were married for over 30 years and had three daughters and a son.
Herbert Woodrow, professor of psychology at the University of Illinois at Urbana-Champaign and president of the APA, was searching for someone with a background in multivariate methods to establish a research laboratory. Cattell was invited to assume this position in 1945 and he accepted. With this newly created research professorship in psychology, he was able to obtain sufficient grant support for two Ph.D. associates, four graduate research assistants, and clerical assistance.
One reason that Cattell moved to the University of Illinois was that they were developing the first electronic computer, the Illiac I there, which made it possible for him to complete large-scale factor analyses, which had here-to-fore been impossible to conduct. At the University of Illinois, Raymond Cattell founded the Laboratory of Personality Assessment and Group Behavior. In 1949 he and his wife, Alberta Karen Cattell, founded The Institute for Personality and Ability Testing (IPAT) . Karen Cattell served as director of IPAT until 1993.
In 1960, Cattell organized and convened an international symposium to increase communication and cooperation among psychological researchers who were using multivariate statistics to study human behavior. This resulted in the foundation of the Society of Multivariate Experimental Psychology. He remained in the Illinois research professorship until he reached the University's required retirement age in 1973. A few years after he retired from the University of Illinois he built a home in Boulder, Colorado, where he wrote and published the results of a variety of research projects that had been left unfinished in Illinois.
In 1977 he decided to move to Hawaii, largely because of his lifelong love of the ocean and sailing (see his first book Under Sail Through Red Devon which he wrote about his early years of extensive sailing around his home in Devon, England). He continued his career as a part-time professor and advisor at the University of Hawaii. He also served as adjunct faculty of the Hawaii School of Professional Psychology, which became the American School of Professional Psychology. After settling in Hawaii he married Heather Birkett, a clinical psychologist, who later carried out extensive research using the 16PF and other tests. During the last two decades of his life in Hawaii, Cattell continued to publish a variety of scientific articles, as well as books on motivation, the scientific use of factor analysis, two volumes of personality and learning theory, the inheritance of personality and ability, structured learning theory; and co-edited a book on functional psychological testing, as well as a revision of his Handbook of Multivariate Experimental Psychology.
Cattell and his wife Heather Birkett Cattell lived on a lagoon in the southeast corner of Oahu where he kept a small sailing boat. Around 1990, he had to give up his nearly 80-year sailing career because of navigational challenges resulting from old age. He died peacefully at home in Honolulu on 2 February 1998, at the age of 92 (one month short of 93). He is buried in the Valley of the Temples on a hillside overlooking the sea.  Consistent with his will, his remaining funds have been used to build a school for underprivileged children in Cambodia .
When Cattell entered the field of psychology in the 1920s, he felt that the domain of personality was dominated by ideas that were largely theoretical and intuitive with little research basis. Cattell believed in E.L. Thorndike’s empirical viewpoint that “If something actually did exist, it existed in some amount and hence could be measured.”
Cattell found that concepts used by early psychological theorists tended to be subjective and poorly defined. For example, after examining over 400 published papers on the topic of "anxiety" in 1965, Cattell stated "The studies showed so many fundamentally different meanings used for anxiety and different ways of measuring it, that the studies could not even be integrated.”. Early personality theorists tended to provide little objective evidence or research bases for their theories. Cattell wanted psychology to become more like other sciences, where a theory could be tested in an objective way that could be understood and replicated by others. In Cattell's words:
- “Psychology appeared to be a jungle of confusing, conflicting, and arbitrary concepts. These pre-scientific theories doubtless contained insights which still surpass in refinement those depended upon by psychiatrists or psychologists today. But who knows, among the many brilliant ideas offered, which are the true ones? Some will claim that the statements of one theorist are correct, but others will favour the views of another. Then there is no objective way of sorting out the truth except through scientific research."
Psychologist Art Sweney, an expert in psychometrics, summed up Cattell’s methodology:
- “He was without exception the one man who made the most major strides in systematizing the field of behavioral science from all of its diverse facets into a real science based on empirical, replicable and universal principles. Seldom has psychology had such a determined, systematic explorer dedicated not only to the basic search for scientific knowledge but also to the need to apply science for the benefit of all.” 
In 1994, Cattell 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 IQ research following the publication of the book The Bell Curve.
Rather than pursue a “univariate” research approach to psychology, studying the effect that a single variable (such as “dominance”) might have on one other variable (such as “decision-making”), Cattell pioneered the use of a multivariate approach to psychology. He believed that behavioral dimensions were too complex and interactive to fully understand one dimension in isolation. The classical univariate approach required bringing the individual into an artificial laboratory situation and measuring the effect of one particular variable on another, while the multivariate approach allowed psychologists to study the whole person and their unique combination of traits in a natural environment. Multivariate analyses allowed for the study of real-world situations (e.g. depression, divorce, loss) that could not be manipulated in a laboratory.
Cattell applied multivariate research to three domains: the traits of personality or temperament, the motivational or dynamic traits, and the diverse dimensions of abilities. In each of these areas, he thought there must be a finite number of basic, unitary elements that could be identified. He drew a comparison between these fundamental, underlying traits to the basic elements of the physical world that were discovered and presented in the periodic table of the elements.
In 1960, he organized an international meeting of research-oriented psychologists, resulting in the founding of the Society for Multivariate Experimental Psychology, and its journal, Multivariate Behavioral Research. He brought many researchers from Europe, Asia, Africa, Australia, and South America to work at his lab at the University of Illinois. Many of his books were written in collaboration with others.
Cattell noted that in sciences such as chemistry, physics, astronomy, and medicine, unsubstantiated theories were historically widespread until new instruments were developed to improve scientific observation and measurement. In the 1920s, Cattell studied under Charles Spearman who was developing the new psychometric technique of factor analysis in his effort to understand the basic dimensions and structure of human abilities. Factor analysis became a powerful tool to help uncover the basic dimensions behind a confusing array of surface variables in a particular domain.
Factor analysis was built upon the earlier development of the correlation coefficient, which measures the degree to which two variables are related or tend to go together. For example, if "frequency of exercise" and "blood pressure level" were measured on a large group of people, then inter-correlating these two variables would indicate the degree to which "exercise" and "blood pressure" are directly related to each other. Factor analysis performs complex calculations on the correlation coefficients among a multitude of variables in a particular domain (such as abilities or personality) to determine the basic, unitary factors at work behind the superficial variables of behavior found in that domain.
While working at the University of London with Spearman exploring the number and nature of human abilities, Cattell postulated that factor analysis could be applied to other areas beyond the domain of abilities. In particular, Cattell was interested in exploring the basic dimensions and structure of human personality. For example, he thought that if factor analysis were applied to a wide range of measures of interpersonal functioning, the basic dimensions within the domain of social behavior could be identified. Thus, factor analysis could be used to discover the fundamental dimensions behind the large number of apparent surface behaviors and then facilitate more effective research in this area.
In order to apply factor analysis to personality, Cattell believed it necessary to sample the widest possible range of variables. He specified three kinds of data for comprehensive sampling, to capture the full range of personality dimensions:
- Life data (or L-data), which involves collecting data from the individual’s natural, everyday life behaviors, measuring their characteristic behavior patterns in the real world. This could range from number of traffic accidents or number of parties attended each month, to grade point average in school or number of illnesses or divorces.
- Experimental data (or T-data) which involves reactions to standardized experimental situations created in a lab where a subject’s behavior can be objectively observed and measured.
- Questionnaire data (or Q-data), which involves responses based on introspection by the individual about their own behavior and feelings. He found that this kind of direct questioning often measured subtle internal states and viewpoints that might be hard to see or measure in external behavior.
In order for a personality dimension to be called “fundamental and unitary,” Cattell believed that it needed to be found in factor analyses of data from all three of these domains. Thus, Cattell constructed personality measures of a wide range of traits in each medium. He then repeatedly performed factor analyses on the data.
With the help of many colleagues, Cattell's factor-analytic studies continued over several decades, eventually producing the 16 fundamental factors underlying human personality. He decided to name these traits with letters (A, B, C, D, E…) in order to avoid misnaming these newly discovered dimensions, or inviting confusion with existing vocabulary and concepts. Factor-analytic studies by many researchers in diverse cultures around the world have re-validated the number and meaning of these traits.
Cattell set about developing tests to measure these traits across different age ranges, such as The 16 Personality Factor Questionnaire for adults, the Adolescent Personality Questionnaire, and the Children’s Personality Questionnaire.
From the beginning of his research, Cattell reasoned that, as in other scientific domains like intelligence, there might be an additional, higher level of organization within personality which would provide a structure for the many primary traits. When he factor analyzed the 16 primary traits themselves, he found five “second-order” or global factors, now commonly known as the Big Five. These second-order or global traits were broad, overarching domains of behavior, which provided meaning and structure for the primary traits. For example, the global trait Extraversion emerged from factor-analytic results made up of the five primary traits that were interpersonal in focus.
Thus, global Extraversion is fundamentally related to the primary traits that came together in the factor analysis to define Extraversion, and, moving in the opposite direction, the domain of Extraversion gave conceptual meaning and structure to these primary traits, identifying their focus and function in personality. These two levels of personality structure can be used to provide an integrated understanding of the whole person, with the global traits giving an overview of the individual’s functioning in a broad-brush way, and the more-specific primary trait scores providing an in-depth, detailed picture of the individual’s unique trait combinations.
Research on the basic 16 traits has shown them to be useful in understanding and predicting a wide range of real life behaviors. For example, the traits have been used in educational settings to study and predict such things as achievement motivation, learning style or cognitive style, creativity, and compatible career choices; in work or employment settings to predict such things as leadership style, interpersonal skills, creativity, conscientiousness, stress-management, and accident-proneness; in medical settings to predict heart attack proneness, pain management variables, likely compliance with medical instructions, or recovery pattern from burns or organ transplants; in clinical settings to predict self-esteem, interpersonal needs, frustration tolerance, and openness to change; and, in research settings to predict a wide range of dimensions such as aggression, conformity, and authoritarianism.
Cattell’s program of personality research in the 1940s, 50’s, and 60’s resulted in five books that have been widely recognized as identifying fundamental dimensions of personality and their organizing principles:
- The Description and Measurement of Personality (1946)
- Personality: A Systematic, Theoretical, and Factual Study (1950)
- Personality and Motivation Structure and Measurement (1957)
- The Scientific Analysis of Personality (1965)
- Personality and Mood by Questionnaire (1973)
These books detailed a program of research that was based on personality data from objective behavioral studies, from self-report or questionnaire data, and from observer ratings. They presented a theory of personality development over the human life span, including effects on the individual’s behavior from family, social, cultural, biological, and genetic influences, as well as influences from the domains of motivation and ability.
Criticism and the APA Lifetime Achievement Award
William H. Tucker and Barry Mehler have taken issue with Cattell based on his interests in eugenics, evolution and political systems. They argue that throughout his life Cattell adhered to a mixture of eugenics and theology, which he eventually named Beyondism and proposed as "a new morality from science". Beyondism is based on the premise that groups, like individuals, evolve based on survival of the fittest. Cattell argues that a diversity of "racio-cultural" groups is necessary to allow that evolution. He makes controversial arguments to support natural group selection by encouraging not only the separation of groups but also the prevention of any "external" assistance to "failing" groups from "successful" ones, and by calling for a process of "genthanasia," in which the former would be "phased out" by the latter through "educational and birth control measures"—that is, by segregating them and preventing their reproduction. Cattell's former colleagues and other supporters assert that, although some of Cattell's views are controversial, Tucker and Mehler have exaggerated and misrepresented him by using quotes out of context and from outdated writings.
In 1997, Cattell, at 92, was chosen by the American Psychological Association (APA) for its "Gold Medal Award for Lifetime Achievement in the Science of Psychology." Before the medal was presented, Mehler launched a publicity campaign against Cattell through his nonprofit foundation ISAR accusing Cattell of being sympathetic to racist and fascist ideas and claiming that "it is unconscionable to honor this man whose work helps to dignify the most destructive political ideas of the twentieth century". A blue-ribbon committee was convened by the APA to investigate the legitimacy of the charges. However, before the committee reached a decision, Cattell issued an open letter to the committee saying "I abhor racism and discrimination based on race. Any other belief would be antithetical to my life’s work" and saying that "it is unfortunate that the APA announcement … has brought misguided critics' statements a great deal of publicity." He refused the award, withdrawing his name from consideration. The blue ribbon committee was therefore disbanded and Cattell, in failing health, died months later.
But psychology is a more tricky field, in which even outstanding authorities have been known to run in circles, 'describing things which everyone knows in language which no one understands'.
