 Proponents of clinical equipoise as an ethical requirement for clinical research determine whether equipoise obtains not by appeal to the belief states of individual clinicians, but based on whether there is consensus among the community of experts regarding which treatment is best. Lind believed that sea water was ineffective for the treatment of scurvy. Yet, in the absence of agreement among the community of experts, this view essentially constituted an individual preference rather than a clinical norm. This suggests that it was acceptable for Lind to randomly assign sailors under his care to the prevailing treatments in order to test, in essence, whose preferred treatment was the best. In this way, the existence of uncertainty within the community of experts seems to offer a way to reconcile the methods of clinical research with the norms of clinical medicine.
