I wanted to start a thread on the aforementioned topic because this is a flaw in the INFJ persona that I've noticed from day one. Please know I'm not saying I'm issue free. I'm just saying that INFJ's can sometimes refuse to interpret information because it goes against their preconceived notions of how that information should be presented.
I would agree that INFJ's in particular can appear the most closed of any type to information that does not meet a certain "protocol" standard. The "wrong" facts, said the "wrong" way, at the "wrong" time, by the "wrong" person ... I think what makes it stand out too is that (especially to Pe types) we just accept all input and sort through it after. It's quite startling to us I think to imagine dismissing anything in an initial evaluative gathering of information. Or dismissing information because of anything related to "decorum". Naturally, I still examine the source of the information I gather, but the source does not prevent my consideration of the ideas for their inherent value alone, independent of their origin.
I think what makes it stand out more is that INFJ's in particular
feel more flexy to me externally than they really are internally ... their intuition kind of sends out these (almost seemingly false) openness signals to information gathering, so it can be a surprise to realize and learn that in execution, all input is not considered equally valid from the get-go, and that their minds have (to us, what seems prematurely) closed to certain options and appear intractable to revisit those options.
INxJ's in particular seem often drawn more to information that they are unconsciously looking for. The way they perceive the world has to go in through the Ni filter then come back out to the outer world as judgement on that information. So, they skim, evaluate and thus limit input in order to aid or speed up that process. IxxJ's overall have (in comparison to how I feel about such things) a sense of inner rigidity which can, at times, make the inception of new information into their "inner grid" challenging.
Of course, we Pe types can tend to take in too much info, not be discerning enough about source, consider too many things of equal value when we should narrow focus earlier to our benefit and occasionally dismiss a source as hokey off the hop. "Squirrel?" We simply don't have that initial filter to information that Pi types do. Everything in the direct environment just comes in as it is experienced, everything is initially fair game. Judgement and evaluation only comes later.
Fe / Ti types, in general and in my experience, do tend to assign source credibility a higher value overall and seem more impressed by that. Once you "prove" a certain competence to Fe / Ti, you get to enjoy the benefit of that in a role or as a person for an extended time, whereas an Fi / Te user tends to look more to individual events to form trends that either tend to play out over time or diverge. An example for clarity: as a web developer, I have worked with many INTP's, and if you've got the paper credentials, and then prove to them that not only can you "talk the talk", but "walk the walk" (through the successful completion of a suitably impressive task) you are IN. And then your competency is simply assumed moving forward, sometimes shockingly so haha. INTJ's and ISTJ's, however, want to look more at each individual project you work on and although they form a picture in their mind of what you can do, and there's a sense of trust attached to their belief in your competency, there's never that same sense of being "off-leash".
Hope my vantage point helps contribute to an overall picture here.
