The Five-Factor Model, developed by Costa and McCrae, is a comprehensive framework for understanding personality traits. This model, often referred to as the "Big Five," includes five core dimensions: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. These dimensions highlight how individuals differ in their thoughts, feelings, and behaviors, providing a broad map of human personality.

The model emerged from extensive research and statistical analyses that identified these five factors as the most reliable and valid descriptors of personality across diverse populations. This approach emphasizes the idea that personality is not merely a collection of traits but rather a spectrum that encompasses a range of behaviors and dispositions that can vary in intensity among individuals.

Furthermore, the Five-Factor Model has practical applications in various fields, including psychology, education, and business, as it helps in understanding individual differences, assessing personality for personal development, and enhancing interpersonal relationships. Its wide acceptance in personality psychology is a testament to its robustness and utility in capturing the complexity of human personality.
