Thanks for that, celesul. When I see people conversing and citing sources for their ideas, as an INFP, I immediately think that I won't be able to offer anything with credibility to the conversation because facts are expected.
My problem? A disorganized filing system somewhere in my brain. The stuff is there. Now where did I put it?
So my reaction is to speak from experience of encounters with others, to speak from my feelings and my thoughts. These are valid to me and can be useful to others also.
And because I have little motivation to try to force others to change their ideas or behavior it all comes out to a rationalizer as inconsequential.
I suppose, as an INFP, my motivation leans more toward support and encouragement in what others choose for themselves.
