The Standard View of Disability (SVD) presupposes that having a disability invariably worsens a person's quality of life. Some scholars have identified that the judgements of this perspective are informed by an ableism that assumes the able-bodied perspective as the norm and attempts to isolate the body from its social determinants. Here I will try to answer the following questions: Are the generalisations that the SVD presupposes to describe the quality of life of people epistemically justified? What ethical consequences does the SVD entail for health decision-making?
