SilkRoad, I'm responding to your post without having read Fidelia's response, just so my reply doesn't change. We'll see how similar they are
Would ESTJs ever apologise because they sense (or get told!) that they have hurt someone's feelings (ie. "I'm sorry if I made you feel bad"), even if they personally feel that they haven't actually done something wrong - or are they much more the type to only apologise if they are clearly in the wrong? ("I'm sorry I screwed up")
I'm usually pretty resentful about apologizing when I don't feel like I did anything wrong. I'll wait for a while, in the hopes that they'll own up to what I perceive as "their" wrong, and then if a long enough time goes by, I'll make myself apologize just to diffuse the situation.
But if I feel like I did something wrong, I will ALWAYS apologize, because I feel so incredibly bad about it. I will apologize in an overly eloquent and profuse manner, a lot of the time, without meaning to. Back in the day, I would always apologize in writing, because 1) it was less awkward and 2) I'm more well-written than I am well-spoken. Now I don't

but I still think it's a lot easier to do.
Are ESTJs eager to leave the door open in troubled or terminated friendships/relationships, or do they tend to call it day and really move on, even if regretfully? (Would it be regretfully?)
What do you mean by "leave the door open"? You mean, leave the possibility that we'll become friends again?
How would an ESTJ react/feel if they sensed that they had lost the respect of someone who used to respect them?
Oh my god I'd be MORTIFIED. And after wallowing in self-pity for a while (and maybe crying about it!), I would go to insane lengths to gain that respect back. I'm one of those people who would rather be respected than liked (although the choice is really hard!), so I even get uncomfortable just THINKING about that situation. And it would be so much worse if it was someone I had high respect for, like a professor/mentor.
EDIT: One more - do ESTJs use humour to defuse tricky situations, or to try to? If so, is it more because they genuinely feel it's the way to go, or is it more "I'm not sure what to say to this obviously mad person, so I'll try to make a joke?"
When I'm trying to explain a sad situation (be it mine or someone else's), I might try to make it a little more light-hearted. When it involves me, I might try to make it sound like it isn't as big a deal as it is, because I don't want people to dwell on it, because if they dwelled on it, it would kill the mood. But if someone is angry at me, I never, ever do that -- mostly because I get really pissed off when people do that to me. It feels to me like they're ignoring the severity of the situation and are therefore disrespecting me. You can pretty much guarantee that, if I'm angry about a situation and someone makes a joke about it, I'll snap at them and say something like "Come on! This is serious!"
OK, very good. Thanks. I guess it's just about holding my ground if I really do have facts to back up what I'm saying.

Indeed! That is exactly, perfectly right.
You mentioned that they might get grumpy for 10 minutes if what they said was refuted, and maybe I take that too personally. When they get grumpy or whatever, I tend to be thinking, "Jeez, what's his problem? I guess he doesn't want me to refute him anymore. He must just want me to keep my mouth shut and never challenge him. Sheesh!"
What I'm saying is, it seems like a more difficult task then you make it sound. You make it sound like, "Just prove the ESTJ wrong and everything will be peachy." But, my experience is that it's much more difficult/challenging than this. It can sometimes become a very heated fight. Not always - but sometimes that happens I guess with 2 hard-nosed T's!!!
Well, some of it depends on what you're arguing about. If it's something related to morals, or deep personal beliefs that would rile up their Fi, then it's very different and I would recommend trying as hard as you can to not critique them. That's one difference between xNTP and xSTJ objectivity, is that you guys are great at distancing yourself from philosophical ideas, and xSTJs have a hard time not taking them personally and overly seriously (if they believe in them; otherwise it's no big deal). I'll bet it confuses the hell out of xNTPs when that happens, too.

"Wow, I thought you were a rational and analytical person! What the hell happened?!?" Well, what happened was that Fi stepped in and ruined everything.
But I'll bet you're thinking of more factual matters -- and yes, I know I'm making it sound easier than it is, mostly because the process of proving them wrong can be tricky. Once you prove them wrong, it's no big deal, and (unless you're really snooty about it) they will not associate their bad experience with you -- they'll just think "I was proven wrong and it was SO embarrassing because I HATE being wrong and how could I have EVER had such a ridiculous opinion on something???" But if your opinion is the total opposite of theirs, then you need as much evidence as possible to back up what you're saying. Either that, or you need to find other people to agree with you -- that functions just as well, as evidence, for ESTJs, because it shows that you don't have a crazy opinion, and that other people share it, which gives you some credibility.
Well, I think I've bugged you about ESTJ behavior enough in the past, so I won't keep beating a dead horse. It's just interesting to learn how different types approach things. Thanks.
You aren't beating a dead horse! You're
learning.
