 The assumption that people with disabilities will not be able to enter into intimate relationships, or will impose onerous burdens on their intimates, may play a significant role in the routinization of prenatal testing and abortion for disability. The reluctance of many parents to have a disabled child often rests on an exaggerated view of the physical and emotional demands of raising such children, or on a failure to appreciate the capacities of such children to form rewarding parent-child relationships. The latter is likely to play a major role in the strength of the desire to avoid having a child with a serious cognitive impairment. Indeed, surveys show that prospective parents are far more reluctant to have a child with a cognitive or affective impairment than a sensory or motor impairment (Wertz 1998).
