Again, while I certainly see the Ne/Ni difference, I still think there is a great deal of rational reasoning going on (judging functions), at least in my case. I tend to associate the search for truth with my Fi, especially since I am an expressed introvert and spend far more time in introspection than in seeking stimulus.Thanks for playing along. As it happens, I was less interested in your conclusion than what you did with it. After all, functions aren't opinions. Your section above shows the marks of Ne, in that you start off on one subject (power of the president), then branch out to a related but different topic (the morality of military action). Your Ne went looking for observable implications of the presidents power.
If you go back and look at my bit, you will see that my thoughts branched in a different way, looking for other things that had the same fundamental routes. The pope was the example I mentioned. My Ni concerned itself with the causes rather than the subject itself.
This is perhaps themost readily apparent differance between Ne and Ni. IK think there are others, but they are a little harder to pin down!
