Research Summary:

Medical decision science explores how people reason, formulate judgments and make decisions. The term "medical" is used in the broad sense to include all actions that contribute to health. The term "people" is used in the broad sense to include clinicians, patients and policymakers. This field is not limited to doctors or confined to clinical care. The main rationale for this field is that medical care requires judgment, judgment raises the risk of error and error provides an opportunity for improvement.
