This paper argues that accepting incommensurability can be a useful step for developing attractive hybrid theories to how to distribute scarce health-related resources. If one provides opportunity for distributive options to be incommensurable with respect to substantive criteria, one can hold on to substantive criteria while also providing room for decision processes to play a significant role. The paper also argues that the strategy of accepting incommensurability is preferable to the strategy of having substantive criteria establish sets of options that (...) are equally, explains why incommensurability gives us reason to go hybrid, and argues that reasons grounded in decision processes have properties that make them appropriate as “tiebreakers” in choice situations characterized by incommensurability.

Priority setting in healthcare is a highly contentious area of public decision making, in which different values often support incompatible policy options and compromise can be elusive. One promising approach to resolving priority-setting conflicts divides the decision-making process into two steps. In the first, a set of eligible options is identified; in the second, one of those options is chosen by a deliberative process. This paper considers the first step, examining proposals for identifying a set of options eligible for deliberation. (...) It focuses on the approach proposed by Anders Herlitz, which limits deliberation to options that are on a par; neither better or worse than, nor strictly equal to the alternatives. Once these “maximal” options are identified, the choice among them is made though a deliberative process that acknowledges the difficult tradeoffs which must be made. While parity and kindred notions are clearly useful in resolving some priority-setting conflicts, this paper argues that the conflicts that arise in setting priorities make it as difficult to decide which options are on a par as it is to decide among those options. The paper draws on priority-setting debates that occurred during the recent pandemic to illustrate the challenges in identifying eligible options: There may be sharp disagreement about how to understand and individuate relevant values; about whether certain values are relevant in a priority-setting context; about how to establish parity between “consequential” and “deontic” options, and about whether one option remains on a par with others after it is modified in various ways.

This paper introduces incommensurability, its potential relevance to population-level bioethics, and thecontributions to the special issue. It provides an overview of recent research on incommensurability, outlines somereasons to believe in its possibility and relevance, and presents some problems and opportunities that arise onceone accepts that incommensurability is possible.
