 It is not clear that such refashioning would impose the “intolerable costs” feared by Wolff. Social inclusion does not require, for example, that individuals with significant cognitive impairments be able to make binding contracts in every domain of law and business; it requires that competence standards be graduated to reflect the complexity of specific tasks so that those individuals are not categorically excluded –a suggestion made more than two decades ago by the authors of the card-game metaphor (Buchanan and Brock 1990). Social model theorists know full well that impairments—physical as well as cognitive—differ from skin color in that they are sometimes relevant to what people can do, as are such other attributes as education and income. But that feature of impairment hardly precludes social reconstruction. Indeed, the most effective rebuttal to the card-game metaphor may be found in the practical work that already has been done in educational and workplace inclusion (e.g., Biklen 1992; Block 2006; Hehir 2002; McGuire et al. 2006). At the same time, it bears emphasis that the social model of disability was originally conceptualized in terms of physical disabilities. And there may be significant limitations on the extent to which it applies to cognitive disabilities. More generally, although it may be useful to speak of “the” social model of “disability”, the diversity of impairments that fall under the extension of “disability” suggests that the aptness of the social model in any given context will vary depending on the nature of the impairments at issue.
