True, or we actually CAN see within them, and the person is intrigued, speculative, and interested!
Always a matter of approachability, and most INFJ's have that in spades! I'd suggest as a whole INFJ's are disarming, not intrusive in their manner of approach in such a situation. Lean more towards building people up than tearing them down. Disarming is a good word for it, because we'll intrude your headspace and you'll think it was your idea.
What you are describing is one of the worst kinds of intrusion. The person who claims insight without effort and without demonstrating that skill is unlikely to possess it. Even though it can be a natural human tendency to simplify the world around us by making assumptions and imposing various stereotypes, more accurate insight requires a healthy level of respect for the complexity and uniqueness of each individual that is encountered. The person who is going to have the most insight will have both a natural tendency towards perceiving and analyzing thoughts and behavior, but also will put tremendous effort through an ongoing desire to continually learn. People are dynamic systems in a constant state of change. It requires a deep openness to respond to this continual evolution. The quickest way to lose the ability to understand other people in a meaningful way is to assume they are on a lower plane than self (boring, shallow, etc.) and therefore easier to comprehend. That assumption demonstrates an inability to see much detail and nuance in others. All that is perceived is something less than self, something less than the human being the person actually is.

It's funny how you guys look at my comment like brain stabbing and arrogant relational faux pas! LOL! Just not the case if what I've said is done with tact, humility, gentleness and kindness. Again, it's a way of building the person up, not tearing them down but encouraging potential, if a mental leap is made. Of course putting people in a box and labelling them is unproductive and arrogant, but what I've already said is totally different. What you've said sounds like buddha, "blow out the candle of self you must"....lol!
Finding people boring and shallow is personal preference, everyone feels that way about everyone. Everyone loves how everyone else talks? Ya right. Lies. It's not a matter of being lower, so much as it is a matter of learning patience with the naturally irksome. Everyone finds a group of people naturally irksome, there are just some people others have a hard time relating with.
