Okay, I'm a huge Bowie fan and decided to sit through the whole video. I've been trying to figure out his type for a long time now, but Bowie was such a private person that it makes it very difficult to piece it all together. I've read and seen many interviews and documentaries about him as well, so I know quite a bit about him. Honestly though, I'm not sure how anyone can say he's an ISFP, especially after watching the interview 10 minutes in. That is not tertiary Ni at work, sorry. I personally used to think he was an INFJ, but I've seen people make a good argument for ENFP. He's always seemed like a very intuitive person to me in general, from his interests in the esoteric/occult/Kabbalah, the deeper meaning in his songs, the metaphors he uses, not being a natural stage performer, etc. Hell, he even said he was intuitive in this quote:
"I'm terribly intuitive—I always thought I was intellectual about what I do, but I've come to the realisation that I have absolutely no idea what I'm doing half the time, that the majority of the stuff that I do is totally intuitive, totally about where I am physically and mentally at any moment in time and I have a far harder time than anybody else explaining it and analysing it. That's the territory of the artist anyway: to be quite at sea with what he does, and working towards not being intuive about it and being far more methodical and academic about it."
However, in regards to him being an INTJ, I just don't see aux-Te in him, even in interviews and from stories of the people he's worked with in the past. Bowie was softer than Te users and seemed to use Fi or maybe even a more Fi-ish Fe due to his 4w3 enneagram type.
You know, I'm not sure if he's still here, but I'm going to tag [mention=19700]asynaretic[/mention] because he's an avid Bowie fan too, but is a lot better at explaining things than I am. He once gave an interesting take on him being a possible INFJ. It'd be nice to get his input as well, that's if he's okay to do so.
