Why the Big Five?

The Big Five (also called OCEAN) is the most replicated personality model in psychology. It measures five broad dimensions: Openness to Experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Unlike type-based systems, the Big Five gives you continuous scores that are stable over time and predictive of real-world outcomes.

Conscientiousness is consistently associated with job performance across occupational groups (Barrick & Mount, 1991). Neuroticism and Agreeableness are among the strongest personality predictors of relationship satisfaction. Your own traits predict your satisfaction more than your partner's traits do (Bach, Koch & Spinath, 2024).

This test uses 60 items drawn from the International Personality Item Pool (IPIP), a free, public-domain collection of items and scales (Goldberg et al., 2006). The 60-item selection is ours and has not been separately validated.

Common questions

What is the most accurate personality test?

The Big Five (OCEAN) model is widely used in personality research. Unlike MBTI, which assigns you to one of 16 types, the Big Five measures five continuous dimensions. This means your results are more stable over time and more predictive of real-world outcomes like job performance and relationship satisfaction. This test uses 60 items drawn from the public-domain International Personality Item Pool (IPIP).

How is the Big Five different from MBTI?

MBTI assigns you a four-letter type (like INFJ) based on binary categories. The Big Five measures five dimensions on continuous scales, so you get a score showing where you fall on each trait rather than being placed in a box. Studies have found that a substantial proportion of MBTI test-takers receive a different type on retest (Pittenger, 1993), while Big Five scores show much higher test-retest stability.

Can personality change over time?

Yes. Longitudinal research (Roberts et al.) shows that personality traits change predictably across adulthood. Conscientiousness and Agreeableness tend to increase with age, while Neuroticism tends to decrease. These changes are gradual and partly driven by life experiences like career development and relationships.
