 Still: though logically independent of claims about the evaluative import of disability, the medical and social models suggest different views about the impact of disability on well-being, and different views about how disability is relevant to reproductive decisions, medical interventions, and social policy. The affirmational model is likely to be more in sympathy with social than medical models here. Those who accept a social model of disability regard the association between disability and well-being as highly contingent, mediated by a variety of environmental and social factors (Campbell &amp; Stramondo 2017). They also tend to question conceptions of well-being that give a central role to the possession or exercise of the standard array of physical and mental functions, as those conceptions imply, or are often taken to imply, that well-being is precluded or diminished merely by the absence or limitation of those functions (see entry  disability: health, well-being, and personal relationships).  As a result, they generally see the disadvantages of disability not only as externally caused, but as less formidable than they appear to people who view disability in largely biomedical terms. These differences are reflected in the conflicting assessments of life with disabilities found in the bioethics and public policy literature on the one hand, and disability scholarship on the other (contrast Brock 2005 with Goering 2008).
