McCrae and Costa (psychologists)

McCrae and Costa are psychologists renowned for developing the Five-Factor Model of personality, which identifies five broad dimensions that describe human personality traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism. Their work helps to systematically understand individual differences by categorizing core personality characteristics that influence thoughts, feelings, and behaviors. This framework is widely used in psychology for research, clinical assessment, and personal development, providing a comprehensive and empirically supported way to understand how people typically differ from one another.
