 These accounts are attractive in identifying attributes that may offer a more intuitively appealing basis for moral status than practical rationality or self-awareness, and in reducing, to varying extents, the proportion of humanity excluded from full moral status. But because they exclude some humans, and may include some non-human animals, they do not fully capture commonsense views about moral status and will be unacceptable to some philosophers. Moreover, these alternative attributes do not resolve, but merely relocate, the problem of accounting for the threshold and range features of full moral status.
