Recently I was reading this site: INFJ or INFP? a closer look, which was put together by an INFJ to help INFs determine whether they have INFJ or INFP preferences. Though I am an ENFP, I read the many, many pages and found it very interesting, though I don't know if I think absolutely all of it is correct. What I wonder especially is if there is an analogous relationship between ENFP and ENFJ characteristics.
One thing that was especially interesting was the page on "The Self-Disclosure Facet." (You can find it by using the drop-down menu in the corner; there's no direct link to it.) The site's author says that INFPs, favoring Fi, tend not to self-disclose about particular things, though they may share their more abstract or general ideas; whereas INFJs, favoring Fe, tend to actually use concrete examples of self-disclosure in order to facilitate communication between themselves and others.
Do any of you INFPs or ENFPs feel this is a correct assessment, in general? And other types, does this observation seem to square with your interactions with NFPs?
I will come back later to give my answer.
