Yes. I did not say I was stupid. I said I do not understand how a strong belief in freedom and autonomy and choice would be an argument against him being INTJ. I have been classified INTJ multiple times and my heart beats for all these things.
I do not see how Solas is so unstructured and unscheduled. What about that chess game or the whole plan to begin with? Solas did not strike me as spontaneity incarnate.
I wanted to make a joke about him giving the Orb to Cornflakes on an impulse, but then felt bad for assuming that it didn't actually seem like a good idea at the time. 
I'm not familiar enough with the personality categorization beyond the fact that people who are and that know me just nod slowly when I tell them I got INTJ and mutter, "yeah...yeah...yep." a lot. But Solas's dialogue with Sera about revolutionary goals and disposing of those good at chaos and replacing them with able administrators, his talk with the Herald about poise and the importance of appearance before the Skyhold reveal, and his general personality make me think of a very careful, calculated personality that falls prey to passion a few too many times. *shrug* No idea if that has anything to do with it.
I'm always glad to see that I've missed the thread being charming in my absence rather than a fistfight, cheese and TV show arguments aside.
