Does anyone else think Frank Zappa was an INTJ? I've been reading Zappa by Barry Miles and from what I can infer, he seems very INTJ. For instance, he would spend 18 hours a day in his studio dubbing live guitar solos onto studio tracks. He was rational, but his humor/satire often went over the heads of his listeners. He also viewed his live guitar solos as "air sculptures" or as compositions in themselves. Anyone else think he was an INTJ?
