I think it is telling of something too. Socionics Model A's Vital functions "manifest without words" and "in the process of doing things" - that strikes me as relevant.
The thoughts that are easiest for me to articulate are just observations of things I have done and what lessons or knowledge I have taken away from it. Online I see people refer to these as their N=1 experiences.
Fi must have some part in the decisions I make. I retrace the decisions I make better than I can articulate what something made me feel (feelings which may have inspired my decision). So there's that.
