Abstract

Our topic here is uncertainty, especially as this arises in medicine. We are concerned with the uncertainty of diagnosis and of prognosis, and about how this should be communicated and shared between a doctor and patient. We are concerned with the idea that the doctor might rightly take responsibility for some of that uncertainty, in the sense that they may manage it when the patient is unwilling or unable to do so. And we are concerned with the implications that this has for informed consent, for shared decision making, and for other normative dimensions of the doctor–patient relationship. Most centrally we argue that it is best understood, not in terms of informed consent, but in terms of informed trust.
