The thing that I hate about Socionics is how flat a view it has about human growth and development.
The worst part is the concept of the PoLR. It's generally seen as every type's Achilles' heel.
I think the PoLR can be overcome. It will never be your greatest strength but there is a way to balance your type out to the point where the weaknesses of the PoLR aren't as apparent.
I think your dual can be the best resource for this personal growth, but I think even a "conflicting" relationship could be beneficial.
How do you feel about your PoLR function? Do you think it can be overcome?
