Use of the role function.
It seems to me that the role function is a kind of corrective, parental function, that takes over when PoLR pressure or guilt transpires. For instance, my role function is :Se: , and when I feel like I am being lazy, my :Se: kicks in and tries to force me into a kind of tough love mentality with myself, and sort of kicks me out of the habit. However, I believe the real problem with causing my laziness is :Fi: , and :Se: is simply a more pleasant way of dealing with the symptoms of my PoLR, without the pain of trying to cope with the weakness. Any pressure on the PoLR is very uncomfortable, and blaming it laziness, or lack of :Se: , instead of the real problem seems to be at least one of the uses of the role function (at least mine).
Hidden agenda and role functions
I think that the role of the role function is not to take attention from the weak function but rather to support her and create the conditions that you do not feel that much pressure on your PolR function, to provide some kind of hope if you wish...For example, if you have problem with :Fi: it demand you to do something about it, to use your :Se: but not just to do anything but using the objective knowledge collected by your dominanat function :Ne: It seems to me that nor reason for being sador worried to much, as we all have got everything we need to succeed. The worry is only if we hear the concern of the weakest function but prefer to ignore it.
I think that directions in the block superego from the PolR to the role function - sort of activation of the role function by the weakest function and in the block ego from the dominanat/first to the second function. For examle, For ENTP type is natural to use his intuition - create ideas... however if he feels something is not ok with his intuitive feeling than he uses more thinking/ theoretical basis. I am not saying that all what I am saing may be true...just ideas. I have read somewhere that information circultes between the functions. And i have to say more about ENTP. One ENTP person was very kind to share his perspective on working of the functions so it would be interesting to know if it is going to ring the bell for the others...
Happy New Year to all
