RT Journal Article SR Electronic T1 Double jeopardy, the equal value of lives and the veil of ignorance: a rejoinder to Harris. JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 204 OP 208 DO 10.1136/jme.22.4.204 VO 22 IS 4 A1 J McKie A1 H Kuhse A1 J Richardson A1 P Singer YR 1996 UL http://jme.bmj.com/content/22/4/204.abstract AB Harris levels two main criticisms against our original defence of QALYs (Quality Adjusted Life Years). First, he rejects the assumption implicit in the QALY approach that not all lives are of equal value. Second, he rejects our appeal to Rawls's veil of ignorance test in support of the QALY method. In the present article we defend QALYs against Harris's criticisms. We argue that some of the conclusions Harris draws from our view that resources should be allocated on the basis of potential improvements in quality of life and quantity of life are erroneous, and that others lack the moral implications Harris claims for them. On the other hand, we defend our claim that a rational egoist, behind a veil of ignorance, could consistently choose to allocate life-saving resources in accordance with the QALY method, despite Harris's claim that a rational egoist would allocate randomly if there is no better than a 50% chance of being the recipient.
