@Mac: there are at least 4 reasons an Fi-user's reading can be off (personal emotional instability, not having enough back info, laziness aka not doing your research before jumping to conclusions, inexperience, ...)
However. Chances are that, unless they're full blown emotionally unstable, they are on to something. They might not be accurate when they guess as to what it is, but there's something there. It's like ignoring that whining puppy they were talking about before. Me, I always compared it to a frigging bell going off, which I cannot ignore, and the other person doesn't seem to hear. All I want from you is to acknowledge the fact that there *is* in fact a bell. If you're going to insist that there is no bell and I must be insane, I'm going to go mental. For real. Then I'll start wondering what possible reasons you could have for lying to me, hiding the truth for me and why that bell is going off at all. And that's where you get inaccurate. Since there is no way for me to get more information on the bell, I'm going to have to resort to Ne to consider which options are all available, and there will be some crazy ones in there!
Also, when dealing with a rather inexperienced Fi-user, or one that's off their game for some reason, they might mistake certain emotions that have a similar vibe for another. For instance, momentary frustration can look like full blown rage, especially in a debate (like Tallullah talked about). Unfortunately, as Ti-users tend to *like* precision, they refuse the explanation or indication the Fi-user is given as being correct or truthful, and meanwhile imho, tossing the baby out there with the bathwater. Ok, maybe it's not full blown rage, but there *is* something there...plz plz plz take a moment and either explain to us why it's irrelevant/not important/should keep ringing/be ignored or is otherwise covered already and a non-issue, or turn it off coz
it is driving me crazy :steam:

(honestly, let's see you ignore a frigging smoke-alarm going off right next to you and keep drinking tea as if nothing's going on *pouts*)
You can see why at this point you won't get an appology from the Fi-user. You're demanding them to say out loud that there *is* no bell and appologize for even suggesting you are hiding a bell from them. Ironically, *that* would be lying. And most Fi-users are kinda truth-oriented, especially on these things.Dropping it is hard, as that bell is still going. Plz turn it off. Plz, or let us at least help you turn it off. We're worried about you
