Yeah, I've been refraining myself from posting in this thread.
If you want to express something, for any reason or purpose at all, and you do so in a creative manner, then what you do or produce is art.
No type does it "better".
Yea I think that any type is good at whatever art they produce whether it be dance, music, a painting, a drawing, a novel, an empire, or a building, but you can totally say that someone is better at painting a replica of the Mona Lisa than someone else and they're probably a certain type that tends to be able to do that.
Comparing myself to my friend who tested ISFP I would say we are both very artistic and considered pretty good, but we have very different natural styles. We are both capable of imitating each other's styles to an extent I think, but it's very obvious how different we produce art, most obvious example by drawing. She's amazing at copying things from real life, still life. When she doodles she usually doodles people and actual objects based in reality. When I draw I just tend to let whatever flow from my hand. I think she said that she usually has an image in mind of what she wants to draw. I don't usually, and if I do it almost always never turns out how I expected it to. I draw a lot of strange things out of shapes and lines, creatures, or just whatever. Very organic and abstract things. I lack the patience and eye for proportions for copying something from life to make it look so realistic, and she says she just doesn't get how I can let all these things flow out when I doodle around. Our art is very different in these ways, but both I think are equally impressive.
I don't know how much these observations mean, but if it seems to mean anything, well it's interesting.
I think each type is more inclined to a certain type of art than others.
Looking at my mom who I think is ISFJ, she's more inclined to interior design... furniture and very physical things that suit the environment. I have a sense that T types might be attracted to graphic designs too maybe, because of a sense of structure in aesthetics? or maybe I'm BSing heh.
Anyway I love arrrrt... I love seeing ANY type create art. It's quite beautiful, because I think it comes from within.
