A voice in the Wilderness at The Chancellor's New Clothes makes the point of the irrationality so deftly. Why not say a sick person's recovery depends soley on the quality of the doctor (not to say that is not a factor - a factor - not the sole or even the major factor?)

“That’s the most ridiculous thing I’ve ever heard,” he began. “Students have nothing to do with their performance.”
Huh? I looked around the class to see if the other students had heard. They looked at me blankly.
