 Reductionists, by contrast, think that the health of a public is reducible to an aggregation of the health of individuals. This claim about reduction, however, need not signal an aversion to an extensive role for government in protecting or promoting public health. That is, some might deny that there is an entity, ‘the public,’ that matters morally in a way that cannot be reducible to individual interests or values but agree with anti-reductionists about policy measures. For example, it is possible that focusing on measures that reduce the incidence of disease in a population will be better at producing more value for individuals than a focus on treating or preventing disease for individuals. (Rose 1985; Rose et al. 2008) Presumably, various anti-reductionists would argue for a similar conclusion, although they would invoke other values to reach it.
