 Nor is it appropriate to determine whether a person has been made worse off by a given act by comparing the actual value produced for that person by that act against the expected value produced for that person by any alternate act. The proposal here takes no position on whether the expected or actual value approach is correct. But it does take into account that the view that an act can be considered at least as good for a person than an alternate act if the actual value the one act generates for that person is at least as great as the expected value the alternate act generates for that person is inconsistent (Roberts 2009).
