 Many mainstream philosophers and bioethicists question the use of summary health measures in priority setting (Harris 1987; Brock 1995). They argue that their proposed use is based either on a questionable utilitarian assessment of lives as more valuable if they “contain” more utility, or on the controversial distributive principle that society should give scarce goods to those who will benefit most from them. But many still defend the general assumptions about disability and quality of life that informed those measures (Brock 2005). Other philosophers and disability scholars have challenged these assumptions (Bickenbach 2005). Some have gone even further, questioning whether quality-of-life assessments place an exaggerated premium on the prevention or correction of impairments that do not, in hospitable environments, preclude rich and rewarding lives (Barnes 2009a; Asch and Wasserman 2010).
