Big Five Personality Traits (OCEAN)
The Big Five — also known as the Five-Factor Model (FFM) — is the dominant scientific framework for mapping human [[personality]]. It organises personality variation into five broad dimensions, each measured on a continuous spectrum rather than as fixed types. The acronym OCEAN (or CANOE) covers the five factors:
### Openness to Experience
measures imaginative range, intellectual curiosity, and appetite for novelty and ideas.
### Conscientiousness
measures self-regulation, reliability, and the capacity for disciplined, goal-directed behaviour.
### Extraversion
measures sociability, assertiveness, and orientation toward the external world.
### Agreeableness
measures cooperative tendency, empathy, and concern for others’ wellbeing.
### Neuroticism
measures emotional reactivity and susceptibility to negative states such as anxiety, irritability, and low mood.
Unlike personality typologies such as MBTI, the Big Five avoids discrete categories — everyone sits somewhere on each spectrum, and scores are relatively stable across adulthood, though not immutable.

Each of the five domains breaks down into six facets each, giving thirty facets in total. These are from the NEO PI-R model developed by Costa and McCrae, which is the most widely used and researched framework for this level of detail:
