Discover your
Big Five profile.
A free, scientific 120-question assessment based on the IPIP-NEO-PI-R. Understand your personality across five core dimensions and 30 facets.
Start the testThe Big Five model is the most widely accepted framework in personality psychology. Decades of research across cultures and languages consistently find that human personality can be described along five broad dimensions.
Each dimension breaks down into six facets, giving you a nuanced 30-facet profile rather than a simple label. Unlike type-based systems, the Big Five measures traits on a spectrum — there are no "good" or "bad" scores.
This assessment uses 120 items from the IPIP-NEO-PI-R, a public-domain instrument developed to measure the same traits as the commercial NEO-PI-R by Costa & McCrae. Each dimension captures a broad aspect of personality, broken into six specific facets. There are no good or bad scores — every position on the spectrum carries strengths.
Neuroticism
Emotional sensitivity & stress responseNeuroticism refers to the tendency to experience negative feelings such as anxiety, anger, and depression. High scorers experience intense negative emotions and may interpret ordinary situations as threatening. Low scorers tend to be calm, emotionally stable, and free from persistent negative feelings.
Extraversion
Social energy & positive emotionsExtraversion is marked by pronounced engagement with the external world, sociability, and positive energy. Extraverts enjoy being with people, are full of energy, and often experience positive emotions. Introverts lack the energy and activity levels of extraverts, preferring solitude and quiet.
Openness
Curiosity, creativity & imaginationOpenness describes a dimension of cognitive style that distinguishes imaginative, creative people from down-to-earth, conventional people. Open people are intellectually curious, appreciative of art, and sensitive to beauty. They tend to think in unconventional ways.
Agreeableness
Cooperation & social harmonyAgreeableness reflects individual differences in concern with cooperation and social harmony. Agreeable individuals value getting along with others, are considerate, friendly, generous, and willing to compromise their interests for others.
Conscientiousness
Organization, discipline & reliabilityConscientiousness concerns the way in which we control, regulate, and direct our impulses. Conscientious individuals avoid trouble and achieve high levels of success through purposeful planning and persistence. They are regarded as intelligent and reliable.
