When I was Executive Producer of All Things Considered, I would get letters from freelancers who wanted to produce stories for the show. “What subjects are you interested in?” they’d ask. I was mystified and stumbled “The name of the program is All Things Considered! We’re interested in everything!”
I realized later, when this question kept coming up, that people were confusing subject selection with treatment. I drew up a little grid to show the difference between Treatment and Subject.
