Big Five personality model

Big Five (OCEAN) personality model

The Big Five — sometimes called the OCEAN or Five-Factor Model — is the personality framework most widely used in psychological research. It measures five broad traits: Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism.

The model emerged from decades of factor analysis on natural-language adjectives, not from a top-down theory. The same five factors appeared across English, Mandarin, Spanish, German, Turkish and dozens of other languages — that cross-cultural consistency is why the model is the academic default. Each trait is independent: a high score on one says nothing about your scores on the others. The Big Five predicts job performance, relationship satisfaction, longevity and creative output, but does NOT measure intelligence, ethics or skill at any specific task.
