A state of genuine uncertainty regarding the benefits or disadvantages of either therapeutic arm of a clinical trial; because a clinical investigator may become biased as a clinical study progresses, given his or her perception of the benefits or adverse effects of one of the therapeutic regimens being evaluated, he or she may enroll fewer and fewer patients in the arm perceived to be less beneficial (due to ethical considerations), and may ultimately defeat the very purpose of the study due to lack of patients in the control arm. A moral exit to this dilemma known as “clinical equipoise” is possible, since genuine uncertainty exists in the expert medical community at large; the investigator may thus continue to enroll control patients “blindly”, despite his or her bias.
