I must say, umop_3pisdn, INTJs such as yourself are redeeming of the whole type in my eyes.
Thank you. That's quite the complement. Though there are many INTJ's I respect more than myself. At least, they strike me as wiser.
Though I, too, am often prone to the "emotions are stupid!" mindset. It's usually because I'm uncomfortable with how much power feelings actually have over me.... It adds additional complications to something I used to think I had figured out. And it's not really my primary way of operating. I often have to remind myself to carefully examine my feelings, when I feel my anxiety begin to rise (a good indicator, I find).
Before, I never did that, and emotions would just blind-side me and sweep me up in their current. I wouldn't know how to deal with them, and if they were intense, it nearly always ended up in mismanagement of the emotions. Perhaps even tragically. Like rejecting romantic advances from people I
liked, because I was uncomfortable with the affection!

Eventually I started to realize it was very self-defeating, and indicative of a larger root problem. So I still sort of decided on logical terms that it just had to be dealt with sooner or later.
When I was younger, I used to take this to mean that the emotions were compromising my clarity of perspective. The thing that was, that those emotions I repressed ended up seeming very important, once I was open to accepting my weakness. This often can be quite contrary to most young INTJ's lines of thinking. We sort of strive to project an ideal image of ourselves, devoid of personal weakness (well, can't speak for all INTJ's, but I'll admit to it.) I probably wouldn't quite word my posts in the way that I do, if this weren't this case. Logically, I could say I find it "unbecoming" of how I view myself, as a writer and somewhat of a perfectionist. I demand a certain level of quality from myself, which is usually the highest I'm capable of, at that time, and granted it's an area I feel competent in.
I think it's mostly dependent on degree. Those who are really dogmatic or extreme about such preferences, are probably more prone to the weaknesses of their type.
