Curious why you react the way you do? **Big Five Personality Test** is the scientifically validated personality assessment used by researchers and clinicians for over forty years — the OCEAN model. In about seven minutes you'll see where you sit on each of the five core traits: **Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism** — compared to global norms.
This is a tool for self-reflection, not a clinical diagnosis. Your results are a starting point for self-awareness, not labels.

**Why this app exists**
Most personality apps are MBTI dressed up as science. The Big Five (OCEAN) is the personality framework that actually has decades of peer-reviewed evidence behind it — the model that academic psychologists, recruiters, and serious researchers use. We wanted a beautiful, clear, completely-on-device version of it that anyone could take in seven minutes.

**About the science**
The BFI-2 (Soto & John, 2017) is one of the most widely cited Big Five inventories — published in *Journal of Personality and Social Psychology* and used in thousands of studies. Percentiles are computed against published norms using a normal-distribution model. The Pro test follows the NEO PI-R taxonomy of six facets per trait — the framework that has shaped industrial-organizational psychology for decades.
