Abstract
Often, a health resource distribution (or, more generally, a health policy) ranks higher than another on one value, say, on promoting total population health; and lower on another, say, on promoting that of the worst off. Then, some opine, there need not be a rational determination as to which of the multiple distributions that partially fulfill both one ought to choose. Sometimes, reason determines only partially, intransitively, or contentiously which of the many “compromises” between these two values is best or most choiceworthy. Norman Daniels, Ruth Chang, Martijn Boot, and Anders Herlitz affirm this opinion, which I shall call “value incommensurability,” “rational underdeterminacy,” or “reasonable disagreement.” To decide between the multiple reasonable compromises on health resource distribution, these philosophers recommend a deliberative democratic process, on two main grounds. First, in such situations, deliberation can produce the determinacy needed for decisionmaking. Second, by treating respectfully and justly even those patients or communities for whom the distributive compromise selected is bad, deliberation shields the legitimacy of that policy. Increasingly, practically-oriented bioethics recommends democratic deliberation even more expansively than these philosophers do—for nearly every decision on health resource distribution and not only when values are incommensurate—on these two grounds and on others. And one could propose a more modest variant on this expansive move as the justification of democratic deliberation. I argue that none of these moves warrants democratic deliberation on health policy.
