What we need in medical schools is not to teach empathy, as much as to preserve it. The process of learning huge volumes of information about disease, of learning a specialised language, can ironically make one lose sight of the patient one came to serve; empathy can be replaced by cynicism.
Students undergo a conversion in the third year of medical school - not pre-clinical to clinical, but pre-cynical to cynical.
Certainly when I got to medical school, I had role models of the kind of physicians I wanted to be. I had an uncle who, looking back, was probably not the most-educated physician around but he carried it off so well.
