Regarding the first - No, I don't think people necessarily induce Fe in me. I mean, Fe is being aware of how everyone is getting along in the current situation and how much effort there is on each person's part to adjust to each other and make the experience as positive as possible for everyone involved. It also is aware of who sticks out and who doesn't (whether it is mood, awkward behaviour, admireable characteristics, whatever). It assesses all of the interconnections and relationships between people (or the ideas they are attached to) that may be relevent to be aware of when trying to interact with them. It's not something that I choose to do, it just is.
I suppose there's all sorts of ways that information can be used positively or negatively. If I perceive that someone is making an effort to adjust to me (or those I care about), assist or cheer me, show consideration for what matters to me etc then I will probably cut them way extra slack and also feel a closer bond to them because they have deposited something in their emotional bank account with me that is accruing interest. It also means they have something to draw from and if they get overdrawn from time to time, I'll probably make up the difference.
Depending on how close I am to the person and how often they make deposits, the amount I'm good for covering may be quite different. That's why it may seem to some that I make assumptions/am judgemental about someone, say like what happened earlier in this thread. If I don't have much history or the history I do have with the person is negative, they are making withdrawals when there is no money and no potential for overdraft and it feels like a demand or assumption to cover it, rather than a request (hence INFJs appearing picky to those people about how they are approached). It is also why I tend to be too lenient if I have extensive history with someone or if I feel like I understand why they haven't made any recent deposits.
2) Can you give an example of how you would adjust to something with Te? Think of the kind of run-in that might be common with you and an INFJ.
