 There are also more self-interested possible bad consequences to consider. Failure to treat infants as having FMS might lead to a lack of tenderness toward them, and thereby contribute to their turning into people who will mistreat us when they are older (Feinberg 1980, p. 198). Moreover, a rule of treating cognitively impaired human beings as having FMS would ensure that we will be treated well should we ever suffer from cognitive impairment (considered without endorsement by McMahan 2002, pp. 227–8).
