The U.S. Commission on Civil Rights has described the "extremely extensive" negative connotations of disability: "To the fact that a [person with a disability] differs from the norm physically or mentally, people often add a value judgment that such a difference is a big and very negative one." [4] Even without evidence to support this supposition, philosophers like Singer are not immune from this bias. In fact, their views seem to emerge from it when divorced from the reality of the lives that disabled people actually live.
In contrast to Singer’s ivory tower speculations, the United States Supreme Court has acknowledged that "society's accumulated myths and fears about disability are as handicapping as are the physical limitations that flow from actual impairment." [5] Regulations and courts addressing job discrimination based on disability under the ADA and other laws have expressly identified the discrimination that results from misperceptions and unrealistically low expectations of what people with disabilities are able to do.
