Abstract

It is widely agreed that first-person testimony is a good source of evidence, including testimony about the contents of mental states unobservable to others. Thus we generally think that an individual’s testimony is a good source of evidence about her wellbeing—after all, she experiences her quality of life and we don’t. However, some have argued that the first-person testimony of disabled individuals regarding their wellbeing is defeated: regardless of someone’s claim about how disability affects her overall wellbeing, other evidence about disability undermines the force of her testimony with respect to our justified beliefs. In this paper, I argue that at least some cases of first-person testimony about disability is not defeated. Particularly, neither the existence of conflicting testimony nor evidence about disabilities’ associated harms or challenges successfully undermine either the content of the testimony or the reliability of the testifiers. While I do not claim that first-person testimony is the only evidence relevant to characterizing disability, I argue that it is not always blocked by other evidence about disability. At least some first-person testimony from disabled individuals is, therefore, undefeated evidence relevant to evaluating disability and overall wellbeing.
