To start, he's definitely an I. He seemed too creative, resourceful, and forward-thinking about the future of society to be an S. He wore colorful outfits and designed the Neverland Ranch... so that seems like an "N." He was definitely F. So that leaves us with INF(?)... Finally, I think he liked cleanliness, order, and timeliness. To keep up his concert schedule, I would imagine that he could have been a J. Plus, this is a man who bleached his skin white, so that all of it would look one uniform color after he was diagnosed with Vitiligo. I doubt a "P" would have done that! I think Michael was an INFJ. Also, dreamers tend to be INFPs, whereas INFJs are both dreamers and doers.
I've done a lot of research on this and reviewed some artwork that MJ had drawn in his younger years to try to get into his mind... My conclusions were that he was very "against the war machine." I believe that he was also asexual (not a pedophile). I discovered on my own that he bears a striking resemblance to the life of Frida Kahlo, who also died around the same age of a physician-assisted suicide. They both had chronic pain, abusive parents (I believe they were physically and sexually abused by their fathers), both had pet monkeys, both had more than 50 unnecessary surgeries, both had high IQ, and both had gender dysphoria. Kahlo was a woman who dressed like a man (and penciled in a unibrow for herself), whereas MJ was a man who identified at times with longer hair and more feminine features. I predicted MJ's death before it happened, since I saw the similarities between these two people. I don't know if that analysis helps, but those were my findings-- I really liked MJ, and think we should count him among us.
