Big Five
Big Five is a popular model in psychology that describes five broad dimensions of personality: openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. This model is used to describe and predict human behavior, personality characteristics, and social interactions.
Openness to experience describes a tendency toward creativity, curiosity, and receptiveness to new ideas. Conscientiousness reflects organization, responsibility, and reliability. Extraversion is characterized by sociability, energy, and optimism. Agreeableness indicates a capacity for cooperation, trust, and compassion. Neuroticism is associated with emotional instability, anxiety, and a tendency to worry.
