I find this question on some forum, so I am interested what do you think.
Is Sound designer artist or technician?
Some say it should be added Psychologist?
An artist is an artist.
Yes, you may operate equipment, which is also what technicians do.
Yes, you may study or be influenced/inspired by human psychology, which is what psychologists do.
But to consider an artist a technician would be a bad analogy. To consider an artist a psychologist would be a false analogy. Art is not about equipment, art is about human expression and/or the creation of beautiful or interesting things. Nor is art genuinely (in a scientific way) about human psychology. Technology (and designing, operating and installing it) on the other hand is about equipment and getting useful things done.
