I"ll do you one better.
I'll provide one of the dissimilarities you were clamoring for.
INTJs seem to find it very hard to admit when they are wrong, or even when they may be wrong. Nothing in Snowden's statements point to a certainty in correctness, to a belief that he is correct enough to be able to determine whether the NSA is correct or not. He believes that people should be informed so that they can decide. This is one of the things that convinced me. You even allude to this difference between INTJs and INTPs in your penultimate post by criticizing my "failure to conclude."
Of course, I'm sure that now, this will not be good enough.
I can ask you more questions, but you'll just respond with more one word answers and not actually back up your claims that you are someone who '"understands" typology. You didn't do that above, I don't expect you to do that anywhere else. You did not provide an explanation of the four functions that you claimed you understand so well. Why should I believe you, when you seem afraid and reluctant to even attempt this?
Your convictions are not ironclad evidence.
I knew someone who was convinced that a new utopia would emerge in December 2012. This conviction was, obviously, not the same thing as truth.
Start discussing the same things I'm discussing and giving real responses and counter-analysis and perhaps I'll change my mind. I guarantee you that no one will be convinced if you continue to present your feelings dressed up by table scraps of data, and perhaps I'll change my mind.
