RT Journal Article SR Electronic T1 The Gettier Problem in informed consent JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 642 OP 645 DO 10.1136/jme.2010.041939 VO 37 IS 11 A1 Shlomo Cohen YR 2011 UL http://jme.bmj.com/content/37/11/642.abstract AB The duty to procure informed consent (IC) from patients before any significant intervention is among the pillars of medical and research ethics. The provision by the doctor of relevant information about treatment and free decision-making by the patient are essential elements of IC. The paper presents cases of IC where the free decision about treatment is not causally related to the information provided, and claims that such cases pose a difficulty parallel to that presented by the Gettier Problem in epistemology. In analogy to the original problem with the concept of knowledge, these Gettier-type cases show an indeterminacy in the concept of IC: we either need to add some explicit additional condition of causal connection between information and consent, or else we should understand the concept in a new way—specifically, since the practice of autonomy necessarily involves some consideration of the relevant information, we must understand free consent in a way that no longer refers to patient autonomy.
