It is hard to explain to non-NTs (ENTJs are similar in their high standards as well) because they think that I or other INTJs are just being argumentative or stubborn. It is absolutely nothing personal, but INTJs just have a hard time letting go of issues that are not thoroughly thought out. There are times when I will hold myself back and will refrain from discussing issues as I do not want to disrupt the harmony of a moment, but in my mind, I turn the issues over and over again in my head sometimes even for days after. I have been told that I am complex and intense. This is not always said in flattery as sometimes people have told me that I think too much and need to let things go. However, this is who I have been since I was a child of 3 or 4 (my earliest memory), and I accept myself as I am and frankly, after much self reflection and self criticism in my life, I like who I am. Still, I do not want to inconvenience others or make them uncomfortable. Now, there are INTJs who may be more egotistical about proving their point, but that is probably due to another issues that they may have, such as insecurity, narcissism or bi-polar disorder. Most INTJs that I have met are just very cerebral, intense and misunderstood. So, next time someone seems intense and argumentative, as long as they are not criticizing or putting down others, reflect on them, and think whether they may be an INTJ. Under that cerebral cloak, we are actually very ethical and fair people. Make your case logically, and we are also very open-minded.
Please comment on your experiences with INTJs or whether you relate to this if you are an INTJ.
