It’s very difficult to arrange an experimental setup for “no treatment at all”, because even enrolling people in a study can be considered a “treatment”—it’s an expectation-inducing intervention with perforce no control group.
I agree that it’s the partition you want, and I’m not saying it’s impossible, but—can you come up with a specific way of running such an experiment?
