This is not so much raw memory, but just, direction.
One ISFp I know talks about becoming
forgetful in relationships, and, automatically resets to peacefulness, "forgetting" conflict. It is a very alpha approach, and has gotten him into trouble. For Si types in general, this seems to be a problem, because sooner or later things just 'reset', and it is like all

direction gets lost, and has to be rebuilt.
I am realizing this in myself, in terms of my morals and beliefs and life direction. It is like I make progress and I keep 'resetting', it is very strange. It very much seems like weak Ni, would you agree? Like I will think I have a course or idea figured out, or where I am supposed to go, and I can get motivated about it for a while, but then it just resets to present moment.
Particularly, because I heard some notes from the recent socionics meet that people might focus too much on their polr - I wonder if that is the case with me. I talk about Ni so much because I am clueless about it, perhaps I should actually "think less" about it (in some ways), and just focus on what is concrete?
Did anything come up about thinking about your polr in the 'right' way? If so, I would be very interested in that. It seems when I really focus on it, I just become complacent and indolent and lazy, which is very dissatisfying.
