I don't know how good that test is. Here's my answers where I assume these are said to me hypothetically ("someone" = me)
So going through this, I can see more than one way to arrive at the same kind of answer.
"Ti: someone is being inconsistent or unfair, not following the rules"
- Indifference if I already have my opinion on it but if I don't understand where they are coming from, I'd ask about it more and be pretty interested in making sense of it.
"Te: someone is doing a task in the wrong way, is not making themselves useful, or is not making sense in their behavior"
- Irritating. Couldn't care less about the "useful" part, since I have my opinion on that already.
"Fi: someone is being mean or insensitive or doing something morally wrong"
- Indifferent or sometimes I would try to understand what they mean, again interested in making sense of the issue.
"Fe: someone is being emotionally closed or indifferent, or has a bad attitude which is affecting others"
- For the former part: I would feel weird/uneasy and not entirely understanding it? For the latter, either very annoyed and/or I'd want to understand what they mean.
"Si: someone is creating conflict or unpleasantness, or isn't taking good care of themselves"
- At unease for the former part, indifferent about the latter, actually hard to imagine being told this / dismissal.
"Se: someone is being lazy or out of touch with reality"
- Former: indifferent (see above for "useful", same thing). Latter: again hard to imagine this / dismissal.
"Ni: someone is acting without thinking of the consequences, or isn't making adequate preparation for something"
- Either hard to imagine this too or where I can imagine it, often dismissal. I do not prepare as much as some IxIs seem to but I do not prepare less than I need to. While IxI runs around worried, I know perfectly well it will all be fine and I can even deliberately piss them off more for fun (not out of bad intentions).
As for considering consequences, I decide myself when I am able to learn from mistakes by drawing the final conclusions and when I still need to analyze more to understand. Then my future actions depend on that. ...EDIT: this is true of only logical stuff. With people related stuff, I can take advice on this actually.
"Ne: someone is being close-minded or not considering something from a different perspective"
- Blah, fuck off. Usually these people are no more open-minded, they seem just as convinced about their viewpoint as I am about mine, at least they certainly do not try to consider mine.
