I am not suggesting every INTP does this, or that every person who ignores another must be an INTP.... It is simply a trend I have noticed with some of my INTP friends and I wanted to get some feedback on it.
I've seen quite a few INTP posters on various boards talk about how if they meet someone who has knowledge that they don't, they will want to (and often do) pepper that person with hundreds of questions to get the knowledge for themselves. I've experienced this for myself as well with some of my INTP friends, and even my INTP dad. When someone is interesting to them, then they are fully engaged.
What I wonder is what happens afterwards. Do you, as an INTP, find yourself ignoring that person once the information has been harvested? Or do you not even notice that you have stopped talking to that person?
