I think that almost any type could be an artist of one form or another.
What about comic books? Couldn't an INTJ [or any type of NT for that matter]become an awesome comic book artist [or comic book writer for that matter]? I mean some forms of art are very precise and technical. What about medical journal illustrations?
Aren't these done by artists?
I mean what is art anyway?
When you really start to dissect this question, there doesn't seem to be a pat answer. Art is kind of like beauty, as they say, "in the eye of the beholder." All of us have the power to create and that is what art is, I think, using that which is to create that which hitherto, was not. If you can imagine and if you can give the imgination form, then you are an artist, at least in some capacity, regardless of type. So, which NT type is the most artistic? Whichever one imagines a design, a plan, a play, a song, a novel, a movie, a superhero, a cartoon, a video, a dance, etc...and sets out to give it a form that can be shared with others....and that could be anyone at any time.
