With 3,000+ studies and validation in 70+ languages, the Big Five (OCEAN model) is the gold standard of personality assessment. Unlike MBTI, where 50% get a different type on retest, Big Five scores are highly stable and predictive of real-world outcomes.
Big Five is ~2x more accurate than MBTI at predicting life outcomes (Scientific American). Conscientiousness alone predicts job performance across all occupations.
When your team takes the test together, AI creates a team personality profile showing how your OCEAN mix affects collaboration. High Extraversion + Low Agreeableness? Expect energetic debates. High Conscientiousness across the board? Great execution, but watch for resistance to change.
90% of Fortune 500 companies use Big Five for team development. Team personality diversity predicts innovation, but only when managed well.
Complete the test in 10 minutes and get your Big Five profile instantly. No email required, no paywall for results. See your scores on all five dimensions with explanations of what they mean for your work style, communication, and collaboration.
Over 4,000,000 Big Five tests taken on open platforms worldwide. Our version adds AI team analysis that individual tests do not offer.
The Big Five test measures your personality across 5 dimensions using LIKERT-scale questions (agree/disagree). Each dimension captures a spectrum of traits. Here is what each dimension measures and a sample question.
I enjoy trying new and unfamiliar experiences.
Openness to Experience: measures curiosity, creativity, willingness to explore new ideas. High scorers are imaginative and open-minded. Low scorers prefer routine and the familiar. In teams: high-Openness members drive innovation, low-Openness members provide stability.
I always complete my tasks thoroughly and on time.
Conscientiousness: measures organization, discipline, reliability. The strongest predictor of job performance across all occupations (meta-analysis of 400,000+ participants). High scorers are dependable and goal-oriented. Low scorers are flexible but may struggle with deadlines.
I feel energized when spending time with other people.
Extraversion: measures sociability, assertiveness, positive energy. High scorers thrive in group settings and take initiative. Low scorers (introverts) recharge alone and prefer deep 1-on-1 conversations. In teams: the Extraversion mix shapes meeting dynamics and communication preferences.
I prioritize harmony and cooperation in my relationships.
Agreeableness: measures empathy, cooperation, trust. High scorers build strong relationships and resolve conflicts smoothly. Low scorers are more competitive and direct. In teams: high Agreeableness creates cohesion but may avoid necessary conflict. Low Agreeableness challenges assumptions but may create friction.
I remain calm and composed under pressure.
Emotional Stability (inverse of Neuroticism): measures stress resilience, emotional regulation, composure. High scorers stay steady under pressure. Low scorers are more emotionally reactive and may need more support during stressful periods. In teams: the emotional stability mix affects how the team handles deadlines and crises.
Each participant receives their Big Five OCEAN profile with scores on all 5 dimensions. AI explains what your scores mean for your work style, communication preferences, and strengths.
AI visualizes how the team personality profiles combine. See where your team clusters (e.g., mostly high Conscientiousness) and where outliers create productive tension or friction.
AI identifies potential collaboration patterns: which pairs may clash (both low Agreeableness), which pairs complement each other (high Openness + high Conscientiousness), and which team dynamics to watch.
Use the team profile as a discussion starter. Share results in a workshop setting to build mutual understanding. The most valuable insight is often: Now I understand why we communicate differently.
