A: No. Your type is an inborn predisposition, a lasting hard-wiring in the brain that you are born with. Short of a brain injury, your type should not ever change, based on type theory. However, your awareness of your type can change. If you take the assessment multiple times and get different answers, it’s because you’re answering the questions differently. Certain seasons of your life may cause you to highlight certain preferences over others, but it’s your awareness that is changing, not your actual preferences. I thought I was an ESTJ for over a year before I realized my true preference is for ENTJ. Both of my parents have a preference for S as well as all four of my grandparents. Therefore, I grew up in a strong S-cultured family. My preference for N is apparent to me now, but it took a while for me to discover it.
