Parsons is a doctor and medical educator studying how doctors make these decisions, a process known as management reasoning, and how doctors in training develop this ability. The other half is knowing what to do about it — in other words, deciding how to manage a patient’s health condition. Pattern matching, at this level, is essentially the same thing a doctor does when fitting a patient’s symptoms to an illness script. And both doctors’ and patients’ sense of risk and uncertainty are shaped by their experience. It cannot acknowledge uncertainty the way a good doctor can, returning to it with you as your circumstances change.
