As an INTJ, you are Introverted, iNtuitive, Thinking, Judging. This makes your primary focus on Introverted Thinking with an Extraverted Intution.
This is defined as a NT personality, which is part of Carl Jung's Rational (Knowledge Seeking) type, and more specifically the Mastermind or Scientist.
You aren't as openly affectionate as some of you NT counterparts, and this may cause other bloggers to assume you aren't as friendly. Your ideas and actual applications for these ideas are brilliant, however, and you might be more likely to create something masterful on your journal.
No surprise, I'm always an INTJ in MBTI tests. It's pretty boring.
