The greatest potential for divisiveness lies in relationships where j-types have to depend on p-types, or vice versa, due to divergent orientation, focus and approach. Most j-types seem to prefer:

- commitments over freedom;
- structures over flexibility;
- to be systematic as opposed to ad hoc;
- destinations over journeys;
- predictability over novelty;
- to prevent rather than react;
- to control rather than allow;
- to go direct as opposed to meander;
- to do rather than practice;
- and edginess over chill.

Whereas, p-types seem to prefer the reverse. Note that this doesn't necessarily imply that one totally lacks the others inferred perspective.

One might think that these differences would serve to balance a relationship but I have found that they frequently cause death by 1000 cuts. Opinion?
