Has nothing to do with a loop it's how they function they are much more driven based on their internal framework and much more skeptical and hesitant in moving towards new areas of thought. IXTJs function like a waterfall moving towards one direction while IXTP spread themselves out towards different directions with a less powerful "stream". This makes the IXTJ type more conventional and predictable but more determined.
All you're describing is stereotypical J vs P characteristics.
Js are "closed and convergent"; Ps are "open and divergent".
The open and closed parts aren't really even that true.
And for the same reason J and P are labeled differently in Socionics.

"I trust what you are doing though…I just see it a little differently.
I don’t see it as you stepping away from the fire. I see it as the fire directing your course.
No matter how airy or earthy or watery you become... to many of us you will always be...a super nova."
