Frequently Asked Questions

What is the Big Five (OCEAN) model?

It is the gold standard empirical taxonomy of personality, capturing individual differences across Extraversion, Agreeableness, Conscientiousness, Negative Emotionality, and Open-Mindedness.

How does BFI-2 differ from MBTI or Enneagram?

Unlike popular unvalidated typologies, the BFI-2 is backed by decades of peer-reviewed factor analytic research and cross-cultural validation.

Can personality traits change over a person's life?

Personality exhibits moderate to high stability, but normative maturation often brings gradual increases in Agreeableness and Conscientiousness and decreases in Negative Emotionality.

Is my personality profile stored?

No. The profile calculation is purely local and private.
