Again I think some of that is due to my age. The older I get the more I realize how much there is that I don't know. I find that I am more cognizant of the fact that there may be many possibilities I am unaware of or may not have considered. Unfortunately, this sometimes means it takes me quite awhile to make up my mind about some things. (overthinking)
The thing is, I don't see this to this degree in other ISTJs who are about the same age you are.
OK let's look at something else, how do you relate to the following statements:
"Since they have no direct experience with the new concept, they have no tools for knowing how to deal with it or what to think about it."
"The new, the untried can perplex the ISTJ"
When I think about it this makes a lot of sense. ISTJs tend to draw upon history. History has taught me that there is often more to the story and that things are often not what they seem to be.
Do you mind that things are often not what they seem to be? Did you ever mind much?
What some call debating I would definitely categorize as heated arguments. I wouldn't mind debates if all involved remained respectful and civil, but that rarely happens. Since that is the case I try to avoid them.
So some INTP's liking to debate... Thing is this is a really bad heuristics. Say 60% of INTPs enjoy heated arguments and 40% of ISTJs enjoy heated arguments. Then we cannot use this to type. Unnecessary detail, hardly relevant to type. If it was like, 95% of INTPs enjoyed it and 5% of ISTJs did then it would be a lot more relevant.
For instance if someone gives me a job to do I want to know exactly what their expectations are. I want expectations to be clearly outlined. I don't want to be given something to do with no clear idea of what the persons expectations are.
From what I've read about INTPs they would find this very boring. It sounds like many of them want to be given freedom to develop things in whatever manner they deem best. Versus me wanting to know what the expectation is.
Why do you need to know exactly their expectations? INTP may want to know too but for a different reason than ISTJ.
I've evaluated the descriptions for ISTJ, INTP and ISTP so many times. I find aspects of all three descriptions that I can relate to. And aspects of all three that I can't relate to. I read comments on the ISTJ forum and very often find myself shaking my head in agreement. This does not happen nearly so often when I browse the INTP and ISTP threads. When I go beyond the descriptions and observe the actual people, I find ISTJs to be more like minded.
I do feel some similarity between us (I mean I find it really easy to read some of your posts, even if some other posts of yours include another aspect that I can't relate to), and I see how you fit here in some ways, yeah, I'm not debating that part at all.
IxTx and something like Si, that's already a lot in common.
Not sure if this has already been shared, but I found an interesting post on reddit on si-fi loops:
"Because of our dominant Si, ISTJs tend to be most comfortable with stability and that which has already been experienced. Additionally, underdeveloped Inferior Ne leads us to view the future with distrust: we tend to see a number of things that could go wrong in any situation and a smaller number of favourable outcomes. This relationship between Si and Ne (desire for the known and distrust of the unknown) could explain why you feel "neurotic and tightly wound" "anxious" and have the "frequent tinge of dread." Further developing your Ne could help develop a more balanced (i.e. less pessimistic) view of the future, making you less anxious overall.
When in the grip of Ne, an ISTJ will see bigger and bigger negative possibilities until the entire future is a dark cloud. This leads to abandoning systems and stability (Te and Si) in favour of doing what feels right in the moment to the ISTJ: Ne-Fi takes over, and we look like really shitty ENFPs. (For ISTJs, escaping the grip often means riding out the downward spiral until you hit rock-bottom, where you can finally regain clarity and snap out of it.)
Hmm, the thing is, I use a very different coping mechanism (I might've mentioned this before in somewhat less detail): my mind simply blocks out the possibilities, I may see the "worst possible" sometimes but I again try to not focus on that and instead focus on figuring out concrete steps to deal with the situation. Keeping the clarity as much as I can. The thing is though, in complex situations, I end up getting disoriented still, I run around that way, wasting time to find the right direction, and it takes a while to get back on track having found a solution. Strong Ne supposedly would easily find some way out.
The tip about developing Ne to see a more balanced view of a situation... uhh, if this means, "things could go better actually", seeing many positive possibilities, or something, I guess, it works in the sense that it takes the mind off the bad possibility that it got a bit stuck on. So that the focus on it is no longer disproportionately strong.
Well by default, as I said I quickly take the focus away from the Ne stuff by concentrating on objective analysis to find a concrete solution but yes, sometimes it helps make my mind un-stuck if I consider another possibility. The problem is only that it's very hard for me to see a second possibility. Once I see it, I'm fine, and I lose interest in the whole thing actually, that is, in "what could be". It's definitely a relief.
Now with the above idea of developing Ne, the idea of considering more than just a second possibility but actually many/all of them so that it's ensured the focus is not disproportionately on one possible (but unverified) outcome, well it would be extremely hard to get this mindset and I do not feel like I would want to stay focused on such a mindset for long. It would make me feel like I lose my concrete aim and that's not good. All in all, best just not to look at any of the possibilities without concrete reasoning directly leading there.
As for your rumination on past events to glean useful knowledge: welcome to Si, the overly analytical perceiving function. Most often, ISTJs use this analysis to determine systemic improvements (i.e. Si-Te asking "what steps could I have taken in this process to reduce the waste of resources?"). However, once we start developing our Fi in a real way, we begin ruminating on events to find improvements to the personal impact of a situation as well. (i.e. Si-Fi asking "what steps could I have taken in this process to get my friend what I think they needed?")
Ha, well, I relate to analyzing a lot about the F side of things and that coming later in life for me.
An Si-Fi loop skips over the objective logic and doesn't try to learn (or do) anything useful from this rumination. It's more like "here are all the things that went wrong yesterday, and here's why I'm at fault for every single one. There are no solutions: I'm just the worst." In a loop, if an ISTJ forgets their umbrella, then they'll also end up blaming themselves for the rain. (ISTJs can often escape a loop by consciously engaging with Te and objectively assessing the situation.)"
No, I cannot at all relate to this in the way presented. I turn my anger externally instead of onto myself. (No, I don't take it out on innocent people.) To be more precise, I would be angry in general about the situation that includes the rain and the missing umbrella and all that. It doesn't include myself personally. But yes, I can fix it by objectively assessing the situation.
