Why two tests, not one

Different lens, complete picture.

MBTI tells you the structure. SBTI tells you the texture. Together they read like a personality x-ray + behind-the-scenes blooper reel.

FAQ

Common questions

Is this an official MBTI or clinical assessment?

No. DuoPersonica uses an MBTI-style 16-type lens for reflection and entertainment, while SBTI is our own scenario system. Neither should be used for hiring, diagnosis, or clinical decisions.

Do I have to pay?

The core tests, standard reports, and dual comparison are free. Career and relationship deep dives and AI Coach are optional paid benefits.

Can I take just one test?

Yes. MBTI and SBTI can each be completed on their own; the dual comparison becomes available after both results exist.

How are results and account data handled?

Results and account data are handled under our Privacy Policy. You can review the data policy and request an export or deletion of account data.
