MBTI sorts people into sixteen types from how they answer a questionnaire. Dermatoglyphic analysis reads a physical pattern that formed before birth. The practical difference shows up over time: one can shift with your mood on the day, the other cannot.
A questionnaire records how you answer on the day you sit it — useful, and sensitive to mood, context and self-awareness. A biometric reading does not change, because the pattern formed before you were born. Neither replaces the other, and we would rather you knew that before you chose.
