 Though relationship-based accounts differ conceptually from respect-based accounts, they differ little in practical terms. They will identify different human beings as having full moral status only if humans can have the cognitive or other psychological capacities necessary for respect while lacking the empathy or motivation necessary for membership in a moral community (or vice-versa). For example, a moral-relationship account might exclude psychopaths. But so might a respect-based account, if it denied psychopaths autonomy because they lacked the capacity to be motivated by a sense of duty, or more broadly, a capacity to recognize and act on moral reasons (see Shoemaker 2007). A respect-based account might also exclude psychopaths if it attributed their moral deficits to severe disabilities in practical rationality. Relationship-based accounts would, like Kantian ones, appear to set a very high threshold for full moral status. The greater the moral accountability demanded by the relationship, the more difficult it may be to claim that human beings with radical cognitive impairments are capable of participation.
