Let me take you back to an experiment that took place in 1930s New York…..

No matter how many times a child was presented to a doctor, there was a 50% chance that they would be prescibed a tonsilectomy…even if they’d been seen by Doctors many times before who had said that they didn’t need one.

So what’s happening here?
