The Bad-Difference View of disability says, roughly, that disability makes one worse off. The Mere-Difference View of disability says, roughly, that it doesn’t. In recent work, Barnes – a MDV proponent – offers a detailed exposition of the MDV. No BDV proponent has done the same. While many thinkers make it clear that they endorse a BDV, they don’t carefully articulate their view. In this paper, I clarify the nature of the BDV. I argue that its best interpretation is probabilistic and comparative: it is the view that a person is likely to be, all things considered, worse off with a disability than without. As such, Barnes – who criticises the version of the BDV that disability by itself, intrinsically or automatically makes a person worse off – misses an opportunity to attack the most plausible and relevant version of the BDV, and the best version remains unchallenged.

Many endorse the Bad-Difference View of disability which says that disability makes one likely to be worse off even in the absence of discrimination against the disabled. Others defend the Mere-Difference View of disability which says that, discounting discrimination, disability does not make one likely to be worse off. A common motivation for the BDV is the Options Argument which identifies reduction in valuable options as a harm of disability. Some reject this argument, arguing that disabled people's prospects aren't hindered by having fewer options. In this article, I defend the Options Argument by arguing that, in disability cases, possessing a greater number of valuable options seems to overall improve well-being prospects. As such, the Options Argument appears to be sound and – although it doesn't establish the BDV – it lends plausibility to the BDV by identifying a potentially significant cost of disability.
