FAQ
Why does MBTI only rank third?
Despite MBTI's popularity, its scientific validity is questionable. Binary classification too simplified, low test-retest reliability (50% change types on retest), and official version requires payment. Modern psychology better supports continuous scoring systems.
Why does Big Five rank second?
Big Five has solid scientific foundation and high recognition in psychology. But many questions (100+), long test time, and results are too academic, not as intuitive as SBTI.
Should I take multiple tests?
Yes. Different tests analyze personality from different angles, results can complement each other. But if time is limited, prioritize SBTI as it combines accuracy, efficiency, and practicality.
Can these tests be used for recruitment?
SBTI and Big Five are more suitable for recruitment. SBTI has short test time and is free, Big Five has strong scientific validity. MBTI is not recommended as the sole basis for recruitment due to scientific validity issues.
Will test results change?
Personality traits are relatively stable but can be fine-tuned with life experiences. Recommend retesting every 6-12 months. SBTI's test-retest reliability is higher than MBTI, results are more stable.
