So? Spell it out. Don't just disagree with me. Tell me what additional connections or benefits you get from filtering out (or being unable to process) emotional data, as a hard-core T. I honestly want to know.
The answer to this question is not straightforward, but here goes.
First, the benefits of this reality (I don't call it an approach, as it is not usually deliberate) is more in what it enables me to avoid than what it brings in beyond what others might experience. I should emphasize at the outset that I really can't know what others experience, only what I do, which limits my ability to speak comparatively.
Considering part of your earlier post:
You can choose to shut out that data and steer a straight course through life on an even keel. But you'll never really understand or connect with other people. You can't even connect with your own emotions, so happiness will elude you. You'll just have stability and predictability, but not much more. On the plus side, you can probably be more productive, since you can tune out a lot of the irritations of daily life and people.
I do understand and connect with people, but more on an intellectual or mental level than emotional. We connect through sharing ideas, insights, speculations, even arguments. I cannot connect with that many people this way, but when I do, it is just amazing. Exhilarating even. It can be like flying at the speed of light through a mental landscape. I work with many wonderful colleagues, and our interactions frequently dip into this territory.
Moreover, I do experience happiness and even joy, though I do not expressly seek either. I find them to be by-products of accomplishment, learning/growth, creativity, and doing the things I enjoy. So as an aside, I certainly do experience emotions, I just consider them personal rather than the stuff of everyday interactions, and similarly do not intrude on or make assumptions about the emotions of others. I also don't dwell on them overmuch. The experience I described above about mental connection obviously has a significant emotional component. It might for the other person as well, but if it is part of what we are sharing together, it is a very minor part.
Alternatively, you can input that data. Your course will then become a lot more erratic with a lot more collisions and crises. You may feel overwhelmed by data at time and exhaust yourself trying to balance competing agendas and needs (yours and theirs). But ultimately your connections with others will be stronger, and you'll be "handling" both yourself and others better. Happiness will become a possibility.
The effects of these irritations, collisions, and crises cannot be overestimated. They can consume significant energy and attention if I attend to them. This may be in large part because I am not good at attending to them. As you wrote later, if I were more practiced at it I might be able to manage them better. At this point, though, the cost of doing so is usually too high. I have read the advice that effort spent developing your strengths pays richer dividends than that spent working on your weaknesses, and I believe it.
As it is, I do feel I have a significant amount of personal stability, in that I feel very grounded in my life - like I can handle whatever comes along. I wouldn't say it is predictable, though. The stability gives me a firm base from which to take risks and try new things, which can seem unpredictable to others, and sometimes to me. I always have a plan, but it is almost as if its very existence gives me the confidence to depart from it to chase opportunities or try something out. I'm not sure this part is related to emotional processing or lack thereof, but you mentioned it so it seemed worth clarifying.
Does this answer your question?
