The theoretical basis of Steelter:

Raymond Cattell

The Steelter competency assessment test, as well as the psychometric report resulting from the test, are based on the studies of the British psychologist Raymond Cattell. In this entry we will make a biography of the author and we will explain the reason why Steelter uses Cattell's work as a theoretical basis. 

Raymond Cattell was born on March 20, 1905, in a small town in England called West Bromwich. From a young age he developed an interest in science and became the first person in his family to attend college, earning his bachelor's degree in chemistry from Kings College when he was only 19. 

After witnessing the devastation of World War I, Cattell became interested in using science to solve human problems. He received his PhD in psychology from University College London in 1929.

After teaching for a few years at Exeter University, Cattell was invited to teach at Columbia University by pioneering psychologist Edward Thorndike. In 1938, he became a professor at Clark University, and in 1941, he moved to Harvard after being invited by Gordon Allport. In 1945, Cattell took a position at the University of Illinois where he established a research department. At that time, the school was developing a pioneering computer that allowed Cattell to perform factor analysis on a much larger scale than was previously possible. In 1973, Cattell retired from the University of Illinois and finally settled in Hawaii, where he continued to teach, write and enjoy his lifelong passion for sailing. He died on February 2, 1998. 

In addition to his research on personality, motivation and intelligence, Cattell's work with multivariate analysis left a lasting impression on psychology. While previous research in psychology had focused on the study of individual variables in isolation, Cattell pioneered the use of multivariate analysis that allowed researchers to see individuals as a whole and study aspects of human behavior that could not be studied in a laboratory setting.


Cattell is known for his 16 personality factors, with which he and numerous professionals used factorial analysis to identify 16 different fundamental components of personality. He later developed the 16PF personality questionnaire, which is still widely used today. Cattell also influenced the work of other psychologists.
