A new analogy:
How judging the quality of medicine at a hospital by having patients evaluate the doctors? Suppose we took a group of patients that all had breast cancer. Some doctors operate, and we administer the evaluation in the recovery room. Some use chemotherapy, and we give that the patients just after they throw up. Some misdiagnose and tell the patient it’s not cancerous at all. And some give the patients sugar pills and tell them that if they come in once a week and listen to the doctor’s jokes (which are actually quite good), they’ll be cured at moderate cost.
Which doctors will look the best?
How about the hospital? Suppose the doctors are all employees. Will the hospital like the idea of patient evaluations? What strategy will lead to the highest number of patients coming to that hospital?
