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: ##### Openness to Experience The domain most associated with imagination, aesthetic sensitivity, and intellectual curiosity • Imagination — fantasy life, richness of inner world • Artistic Interests — aesthetic sensitivity, beauty in art and nature • Emotionality — awareness of and access to one’s own feelings • Adventurousness — appetite for novelty, discomfort with routine • Intellect — enjoyment of ideas, abstract thinking, debate • Liberalism — willingness to challenge convention and authority ##### Conscientiousness The domain of self-regulation, reliability, and goal-directed behaviour • Self-Efficacy — belief in one’s own competence and effectiveness • Orderliness — preference for structure, tidiness, correct procedure • Dutifulness — strength of moral obligation and sense of responsibility • Achievement-Striving — drive toward goals and excellence • Self-Discipline — capacity to begin and persist at difficult tasks • Cautiousness — tendency to think before acting ##### Extraversion The domain of social engagement, assertiveness, and positive affect • Friendliness — warmth toward others, ease of forming bonds • Gregariousness — enjoyment of crowds and social stimulation • Assertiveness — tendency to lead, speak out, take charge • Activity Level — pace of life, busyness, physical energy • Excitement-Seeking — appetite for stimulation, risk, and thrills • Cheerfulness — tendency toward positive mood and enthusiasm ##### Agreeableness The domain of cooperation, empathy, and prosocial orientation • Trust — assumption that others have good intentions • Morality — straightforwardness, discomfort with manipulation • Altruism — genuine reward found in helping others • Cooperation — preference for harmony over confrontation • Modesty — reluctance to claim superiority • Sympathy — compassion, emotional responsiveness to others’ suffering ##### Neuroticism The domain of emotional reactivity and negative affect • Anxiety — tendency toward worry and nervous anticipation • Anger — proneness to frustration and resentment when thwarted • Depression — tendency toward sadness and discouragement • Self-Consciousness — sensitivity to social judgment and embarrassment • Immoderation — difficulty resisting cravings and impulses • Vulnerability — tendency to panic or feel helpless under stress --- Related notes: [[Steven Kessler 1]]
