FAQ
How is BBTI different from MBTI?
MBTI is based on self-report questionnaires. BBTI derives personality axes from natal chart structure — reflecting innate predispositions rather than self-perception.
Do I need an exact birth time?
Yes. Birth time precision directly affects house positions and the Ascendant. Accuracy within ±5 minutes is recommended.
Why might there be two different results?
Whole Sign and Placidus use different house division methods. When they disagree, it indicates an offset between innate tendency and real-world behavioral expression.
Will my result change?
BBTI is based on your natal chart, so it remains fixed. However, personality evolves through growth, experience, and environment.
