The "16 Personality Factors" is a psychological model developed by Raymond Cattell to assess human personality traits. It identifies 16 distinct factors that describe individual differences in behavior and personality. These factors are measured through a questionnaire, providing insights into how people think, feel, and interact with others. Each of the 16 factors falls into broader categories, such as extraversion, anxiety, and independence. This model helps in understanding personality in various contexts, including personal relationships, workplace dynamics, and mental health. It is widely used in psychology, counseling, and organizational settings for personal development and team building.
