I personally have an issue of giving unsolicited advice. I think it ties into my enneagram more then anything, but I think as an INFJ it effects it to. Unsolicited advice is more or less telling someone what they should or should not do without them asking for such input. In situations where you see something as wrong, bad, good, ugly, scary, etc. it's a natural impulse that I am only somewhat aware of to start putting my two cents into something to make it better or more managable. Recently, I have noticed this being an overwhelming trend for INFJ's. While this trait is not exclusive to INFJ's, it seems like our version of it seems to be focused on social situations, or situations in which some sort of harm to a person could arise. A lot of this solicitation seems to come from Fe and Ti, as I have noticed that FP's and TJ's tend to do this much less frequently then FJ's and TP's (although both of those can do it in completely different ways).
So, my question to you is, how often do you give unsolicted advice? How do others respond do it? Do you ever try to supress it in any way? Discuss.
