Basically, what it boils down to is this.

Career musician: “I remember my science class in 5th grade where we just had to get the right answer or else, so science isn’t creative.”

Most scientists: “I remember my music lessons when I was in 5th grade where I had to just get the notes right or else, so I thought music wasn’t creative, but I stuck with it long enough to realize that isn’t the case, and I really enjoy doing it now.”

The only difference between these populations is that the scientists I’ve known had the good sense not to make blanket conclusions based on something that took place when they were 11, whereas the career musicians are happy to do just that.
