Should I take MBTI or SBTI?
Take MBTI if your employer asks you to, if you want a serious framework for self-knowledge, or if you are reading a personal-development book that references it.
Take SBTI if you want a 3-minute laugh, if you want to share your result in your group chat, or if MBTI has stopped feeling specific enough — SBTI's 27 oddly specific types tend to call people out harder than the 16 MBTI types do.
Honestly? Take both. They scratch completely different itches.
