I'm asking this question because before I hit on ISTJ (which I've tested as more than once now, and I believe is exactly right) I tested as ENFP, INFP and INTP!
I think it's weird that I'm so clearly SJ and yet more than once I tested as NP. I've certainly never deliberately lied, because I've always been intrigued about my genuine results. The above are my favourite N types, so maybe I was subconsciously projecting this onto my answers?
I rejected them because:
ENFP - At the time I thought this was dead-on, except I couldn't understand how I was an extravert. My INTP friend also said it made sense and he always seemed pretty perceptive. This was at the most sociable time in my life, so all I can think of is this rubbed off on me before I reverted.
INFP - I just wondered how this could be right when I'm so pragmatic and organised. I'm no dreamer and not idealistic.
INTP - Just didn't seem right. My first thoughts were that I'm not a geek in anything and I hate science, but I thought maybe I should be more open-minded about what the type meant. Turned out my hunch was right though.
Has anyone else experienced this, or have you always been a clear-cut SJ? Maybe we occasionally have traits which are more pronounced from one moment to the next and this could show in the test results? Are ISTJs malleable/adaptable and could this skew the results?
