Using psychology

I often think about the art.
#I even don't have understanding art :-)


I think that a value of art is how much human who views the art feels, unless a computer or a alien desides value of art.


If my idea is in the right. the art only has to think about how impless viewer.
Then, is specialist of psychology a good artist?


For example, the artist painter, the lyricist, the novelist , director of photography and so on.


Is this nearsighted?
