The thing is that Ozzy Osbourne don't take drugs anymore, since several years know. And he still consistent in his personality throughout the decades. So I don't take that into consideration. If I type the guy he is today, he is an ENFP, and if I type the guy of yesterday, he was an ENFP too.He also took acid every day for an entire year which has undoubtedly complicated things. It's impossible to say how that's affected his brain. Unfortunately I don't think there's any video of him before his acid binge which was around 1968.
Drugs can definitely make typing much more difficult. If you look at Stevie Nicks for example, she comes off like an ESTJ in a lot of recent interviews. If you go back to the mid seventies she comes off as a clear INFJ.
Being aknowledged of the manifestations of the shadow function help to avoid that error. For ENPs, Se is called their "devilish" function. Which means that they can use it to an extreme, but without the practical, down-to-earth style and the dexterity of an SP. For Ozzy it's totally that: he ate bats, was an hardcore alcool and drug user, but he still had no particular ability in the use of Se, even now that he is a quite old man.If anything, that kind of drug abuse points to Se. I fully acknowledge that all types can abuse drugs, including ENFP. I can't think of one ENFP who've completely shut out the world to go on an extended drug binge though.
The ISFP is the quiet sensualist, the stoic sculptor. Theses people fits that description. But not Ozzy Osbourne, he has not a strong interest in scuplting the physical musical form in a subtle and stoic way like them.I can think of some ISFPs:
And theses guys you quoted have not the sensotard-ness of Ozzy, not his goofy and wild exuberance either. You will never find them be as awkward as Ozzy in the video I posted, not either behave like this:
That being said, you may be right. There's something about the way he rambles on that could be the brain-dead version of Ne. I don't really see any actual, practical use of Ne at any point during his career, nor do I see anything that points to NF. Still, despite all that, I can't rule out ENFP.
He does exibit NF characteristics, but as an ENFP, it's mixed with wild hedonism and delusion, the song Crazy Train is an example: it's wild, exuberant, explosive and also has lyrics abstract in speech and oriented toward ethics and appeal to universal love. This and endless mental explorations are strong trends in his music. Ne and Fi above all.
