. . . but the reality is, they do not deal with irrational behavior well. That includes their own irrational behavior, that they themselves are sometimes are susceptible to.
. . .
We do not have a built in mechanism for coping with this other than our analytical skills, which are inadequate to understand this irrational behavior.
I've often thought about this as well. I can remember when I was a child, a lot of times just wanting to remove emotions from myself altogether because they were so distracting and I viewed them as exhausting and a complete waste of time. As I grew older, I realized that most people fell into two general categories, those disposed to dealing with emotions or with logic. And the problem of dealing with others irrational behavior, as well as my own, became more and more something that I wanted to solve, at least to provide a personal way of coping. I've come to the following conclusions, that I've found work well for me:
External Irrational behavior:
This one was easy, and as I'm sure most NT types will agree, ignorance is bliss. As an introvert, it's easy for me to ignore people, to keep completely silent when nonsense is happening. If a person is extremely insistent on my participation, I will oblige in a variety of ways, including, but not limited to; logical dissection, sarcasm, raucous laughter, beratement, contrarianism and so forth.
The key idea being that external irrational behavior is like a fire. It needs fuel to consume, and if I provide no additional fuel, I can be patient and wait for it to burn out. If I can somehow remove the fuel, it will be extinguished. If I can give it too much fuel all at once, I might just let it explode and watch with certain satisfaction as it burns everyone and everything around it.
Internal Irrational behavior:
Dealing with my own nonsense has not been such a strategic progression. I wrote one time in my journal that I felt like my emotions were leaking out of me, in ways I couldn’t predict or control. I thought at one time that, not unlike when I was younger, if I were to just embrace my emotions they would somehow leave me, as if they would get bored with me or something. But the same emotions would come back. And my reaction to them was still unpredictable, even if I was settled on the acceptance of them.
My personal solution? I collect my irrational emotions. I save them. I can’t relish in them by becoming overly happy/angry/sad etc., yet I can’t shave them off because they just come back thicker. So I store them, sometimes labeled neatly, sometimes generalized haphazardly, depending on their volume and/or frequency. I transform them into works of art, or sharpen them into weapons of destruction. I might distill them into harmlessly repetitive actions, or focus them to produce epic, irreplicable feats of physical or mental precision.
