Shotgun

What I was trying to get at, from the previous discussion, is simple: In the old days, when technology is limited, physicians need good clinical skill to formulate a hypothesis - to make a diagnosis that and there, or to determine what (targetted) investigations are necessary to do so.

But, when technology has become sufficiently sophisticated and is cheap and readily available, you don't need a hypothesis to start with - a shotgun approach is simple and practical: Whatever the symptom is, put the patient through a whole body CT (computer tomography) scan or MRI (magnetic resonance imaging) or PET (positron emission tomography) or any other autopsy-equivalent investigation and you will know what's wrong.

In other words, we are almost coming to an age that we may not need a brain to become a physician.

But, what may skip your eyes is: The same phenomenon happens in medical research.
