Heh. I guess that does suck pretty badly. I'm not sure you can ever change someone's mind if they're that close minded. They're more likely to change their mind when it becomes something important to them. Like the mother who stopped believing that vaccines cause autism when she wanted to find other options because her kids were getting sick. I guess all you could do is suggest them and hopefully when they change enough in their life, they'll change their minds too. You could push for them to not be so close minded, but often that results in them believing even more in their beliefs. Though, you'd probably get more of a chance of convincing them if you take time to listen to their thoughts and act like you're considering them before suggesting your ideas. Because without that, you'd seem more like the close minded ones to them. It probably won't work all the time, but it helps in convincing people.
I wouldn't call it exactly a hellhole even when I do consider the flaws but now I think they have their place in society. Often people tend to judge other people by what they're good at. People like us would stress objectivity and skepticism when judging others because we value it in ourselves. Others would value reliability and discipline in judging others because they have it in themselves. But with this view, we limit ourselves to seeing what other strengths other people have that we often can lack.
SJs are called guardians because that's what they tend to be. They maintain ideas rather than forge new ones. While that may seem close minded, it also allows ideas to be implemented and maintained. Which intuitives in general can have trouble doing. All the little practical details we NTs tend to find annoying come more easily to them. And they have their roles maintaining order to follow in everyday life. Obedience in a bad light and to an extreme can be blind faith but used well, it can actually allow ideas to be implemented well in people's lives. I see this at times in a small scale in my own life. I can make more and more ideas and innovate new solutions to things but I can have trouble maintaining and following through with these ideas. So after seeing these "boring" skills like discipline and detail work as actually valuable, I actually was able to gain something from their perspective by working on these traits in my life. Maybe I can't change them, but maybe I can learn from them something I can change in myself.
Okay. I'm not saying that their lack of skepticism does not suck. It sucks and they should change. But I do still have patience with these traits because after all, they're not necessarily bad people. Just people with different strengths and weaknesses. Even if people are in the end wrong in their perspectives, there tends to be some amount of truth and value in ideas sometimes. It gets easier to be patient when you figure out that things higher Ne users tend to find hard like repetitve but needed work and small details is the same with SJs having difficulty in creating their own novel ideas and open mindedness that comes with higher Ne. Or maybe with NT's general value on skepticism.
