Five-Factor Personality Inventory (Big Five)
The Five-Factor Personality Inventory (Big Five) assesses personality across the five dimensions most widely accepted in science: openness to experience, conscientiousness, extraversion, agreeableness, and emotional stability/neuroticism. It produces a profile showing where a person sits on each dimension, scoring on a continuum rather than assigning a single type.
