Raymond Cattell

Raymond Cattell was a British psychologist known for his work in personality and intelligence. He developed the 16 Personality Factor (16PF) model, which identifies essential traits that make up human personality. Cattell also contributed to the study of intelligence, distinguishing between fluid intelligence (problem-solving ability) and crystallized intelligence (knowledge gained from experience). His scientific approach emphasized the use of factor analysis, a statistical method to identify underlying relationships in data, making his theories influential in both psychology and educational assessments. Cattell's work remains relevant in understanding individual differences in behavior and cognition.
