Raymond Bernard Cattell (born March 20, 1905 – died February 2, 1998) was a British-American psychologist. He was famous for his research into how our minds work. He studied different parts of our personality, how we think, what motivates us, and our feelings.
Cattell used a special math method called factor analysis to understand these things. He believed this was better than just guessing. One of his big discoveries was finding 16 main personality traits. He called these "source traits." These traits are measured by a test called the 16PF Questionnaire.
He also studied intelligence. He came up with the idea of two types of intelligence: fluid intelligence and crystallized intelligence. Fluid intelligence is about solving new problems. Crystallized intelligence is about using what you've learned. He also created the Culture Fair Intelligence Test. This test tries to measure intelligence fairly, no matter your background.

Key Discoveries in Psychology
Raymond Cattell made many important contributions to the field of psychology. He focused on understanding personality, abilities, and what motivates people. He also developed new ways to analyze data.
Understanding Personality Traits
Cattell is well-known for his 16-factor model of personality. He believed that personality could be broken down into 16 basic traits. He created the 16PF Questionnaire to measure these traits.
He was also the first to suggest that personality has different levels. There are many basic traits, but also a few broader, "second-order" traits. These broader traits are similar to what is now called the Big Five model. Cattell also looked at how personality traits change as people grow older.
Exploring Different Kinds of Intelligence
Cattell studied many types of mental abilities. His most famous idea is the difference between fluid and crystallized intelligence.
- Fluid intelligence is your ability to think logically and solve new problems. It's like being able to figure out a puzzle you've never seen before.
- Crystallized intelligence is the knowledge and skills you gain from experience and learning. It's like knowing many facts or how to do a specific job well.
Cattell believed that fluid intelligence helps you learn new things. This learning then builds up your crystallized intelligence. He also created the Culture Fair Intelligence Test. This test was designed to measure intelligence without being affected by your language or cultural background.
New Ways to Study Data
Cattell was a pioneer in using factor analysis. This is a statistical method that helps find hidden patterns in large amounts of data. He also developed new techniques for this method.
In 1960, he started the Society of Multivariate Experimental Psychology (SMEP). He also launched a journal called Multivariate Behavioral Research. These helped scientists who used advanced statistics to study human behavior.
About Raymond Cattell's Life
Raymond Cattell was born in England on March 20, 1905. His family was involved in inventing new parts for machines. This made him think about how a few people could make a big difference in the world.
Early Life and Education
When he was five, his family moved to Torquay, England. He loved science and spent a lot of time sailing. At 16, he earned a scholarship to study chemistry at King's College, London. He graduated with top honors at age 19.
After World War I, Cattell saw a lot of suffering. He decided to use science to help solve human problems. So, he switched his studies to psychology and earned his PhD in 1929. He later received another special doctorate from the University of London for his research.
Moving to the United States
In 1937, Cattell moved to the United States. He was invited to teach at Columbia University. Later, he joined Harvard University where he began his important research on personality.
During World War II, he helped the U.S. government. He developed tests to choose officers for the armed forces. After the war, he moved to the University of Illinois. He was able to do large-scale research there because they had one of the first electronic computers.
In 1949, he and his wife, Karen, started the Institute for Personality and Ability Testing (IPAT). This institute helped develop and publish his psychological tests. Cattell retired from the University of Illinois in 1973. He then moved to Colorado and later to Hawaii, where he continued his research and writing. He loved the ocean and sailing.
Raymond Cattell passed away in Honolulu, Hawaii, on February 2, 1998, at 92 years old. He is buried overlooking the sea. He left money in his will to build a school for children in Cambodia.
Cattell's Scientific Approach
When Cattell started his career, he felt that ideas about personality were mostly just guesses. He wanted psychology to be more like other sciences. He believed that if something existed, it could be measured.
He thought that many ideas used by early psychologists were unclear. For example, he found that "anxiety" was used in many different ways. Cattell wanted to test theories in an objective way that others could understand and repeat. He said that psychology was "a jungle of confusing, conflicting, and arbitrary concepts." He wanted to find the truth through scientific research.
Arthur B. Sweney, an expert in psychological testing, said that Cattell helped make behavioral science a "real science." He worked to find universal principles that could be used to help people.
Studying Many Things at Once
Instead of studying just one thing at a time, Cattell used a "multivariate" approach. This means he studied several variables at once. He believed that human behavior was too complex to understand by looking at things separately.
He thought that psychologists should study the whole person in their natural environment. This approach allowed him to study real-life situations like sadness or divorce. These situations couldn't be created in a lab.
Cattell applied these methods to personality, motivation, emotions, and mental abilities. He believed there were a limited number of basic, underlying dimensions in each area. He compared these to the basic elements in the periodic table of chemistry.
Cattell's Personality Theory
To study personality, Cattell collected data in three main ways:
- Life data (L-data): This involved observing people's everyday behavior. Examples include how many parties they attended or their grades in school.
- Experimental data (T-data): This involved observing people's reactions in controlled lab situations. Their behavior could be measured objectively.
- Questionnaire data (Q-data): This involved asking people about their own feelings and behaviors. This helped understand inner thoughts that might not be seen from the outside.
Cattell believed that a true personality trait should show up in all three types of data. After many years of research, he found 16 main personality traits. He named them with letters (A, B, C, etc.) to avoid confusion. Many studies around the world have supported these 16 traits.
He created different tests for different age groups. These included the Sixteen Personality Factor Questionnaire (16PF) for adults. He also developed tests to measure moods and temporary emotional states.
Cattell also found that the 16 primary traits could be grouped into five broader "second-order" factors. These are now known as the Big Five. For example, the "global trait" of Extraversion is made up of several primary traits that focus on social interaction.
Understanding these traits helps predict many real-life behaviors. For example, they can help understand:
- Why some students are more motivated to learn.
- What kind of career might suit someone.
- How people handle stress at work.
- How patients might recover from illness.
Cattell's research led to many important books about personality and motivation. These books showed how personality develops over a person's life. They also looked at how family, society, culture, biology, and genes influence behavior.
Controversy and Recognition
In 1997, the American Psychological Association (APA) chose Cattell for a "Gold Medal Award for Lifetime Achievement." However, some people criticized him because of his past writings about evolution and society. They claimed he had ideas that were seen as unfair or discriminatory.
Before the award was given, Cattell wrote an open letter. He stated, "I believe in equal opportunity for all individuals, and I abhor racism and discrimination based on race." He also said that any other belief would go against his life's work. Cattell then chose to refuse the award. He died a few months later.
Some people, like Richard L. Gorsuch, defended Cattell. They said that Cattell was actually one of the first to challenge unfairness in tests and try to reduce it.
