“It is unsettling to find how little it takes to defeat success in medicine. You come as a professional equipped with expertise and technology. You do not imagine that a mere matter of etiquette could foil you. But the social dimension turns out to be as essential as the scientific--matters of how casual you should be, how formal, how reticent, how forthright. Also: how apologetic, how self-confident, how money-minded. In this work against sickness, we begin not with genetic or cellular interactions, but with human ones. They are what make medicine so complex and fascinating. How each interaction is negotiated can determine whether a doctor is trusted, whether a patient is heard, whether the right diagnosis is made, the right treatment given. But in this realm there are no perfect formulas.”
