So I was just reflecting on my past and psychoanalyzing myself as I often do (I have read that this is common with Si+Ti), and I realized that up until a precise point in my life, I may have been more feeling/emotional than thinking. I've always clearly fit the INTP mold and my childhood was relatively typical of that, but it seems to me their was a certain point (when I started reading about philosophy, history, sociology, etc. in high school) that I made a clear switch to dominant Ti where as before I had retrospectively been more Si and maybe Fe. I think it was certainly related to external factors- not fitting in in high school, an inspiring history teacher, discovering philosophy and sociology- but I am wondering if this is a common experience for INTPs or perhaps just the unique way I developed given my environment and experiences... or maybe just a projection onto past memories which I simply don't remember the stoic Ti as a part of because as a child my Thinking was applied to very different subjects and I didn't recognize it as such; thus I don't remember it as such.
I have read that INTPs who have developed their Si but ignore their Fe often become more reclusive and cynical, while INTPs with a well developed Fe are more sociable and often proud of their eccentricities albeit reserved. Perhaps I switched from Fe to Si as that kind of describes me at 18 vs. me at 14. Again could just be sleep deprived over-thinking on my part (this really isn't that important and I hate to have wasted this much of your time already).
Anyway, what do you think INTPs? Have you ever noticed a major shift in your personality style? Maybe from reclusive to sociable or vice versa? Feeling to Thinking?
