Overview

Big Five Personality Traits

The Big Five Personality Traits (OCEAN model) is the most widely recognized scientific framework in modern psychology for evaluating human personality across five dimensions: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. It was systematized in the 1980s by researchers including Lewis Goldberg and Costa & McCrae, and has been established through over 40 years of research and cross-cultural validation. The model is utilized across diverse fields including human resources, clinical psychology, education, and academic research, with its distinguishing feature being the conceptualization of personality as a continuous spectrum.
