Typological Doh!
Reading Lenore Thomson's Personality Type: An Owner's Manual produced an insight that now seems so flipping obvious/
In Jungian types, the final designation (either P or J) doesn't really have attributes, but it has implications that kind of look like attributes. The common assumption is that J types are more scheduled and organized, while P types are more creative and spontaneous. More specifically, J implies the ability and tendency to be decisive, whereas P more implies the ability and tendency to keep options open. The drawbacks being, of course, that J's can be judgmental and P's can be flaky.
This works for extraverted types, because for an extraverted type, the function that the P or J modifies is that individual's primary function. So, an ENTJ's primary function is extraverted Thinking, which is the Judging function.
But for introverts, the opposite is true. The P or J modifies the secondary function, which means that the introvert's primary function is opposite the one modified by P or J. So, an ISTP's primary function is not extraverted Sensation, which is the function modified by the P, but it is the J function, introverted Thinking.
So, if it really does follow that J functions are more conclusion-oriented, then iPs are more likely to make judgments than iJs. The difference, I think, between an eJ and an iP would be then that the eJ would apply that judgement to extraverted activities, like being somewhere on time, while an iP would apply that judgment to interior activities, like personal taste (including opinions about people).
I'm leaving out a lot of type mechanics here, so I may lose most people. I'd be more than happy to explain to anyone who's interested. But I just wanted to capture this, because it was such a Doh!
