 Many critics have found Rawls’s argument for the difference principle unconvincing (see, for example, Kymlicka 2001: 60–70). They ask why people behind the veil of ignorance would not choose to gamble, selecting an alternative principle that is less favorable to the disadvantaged in society than the difference principle but which would give higher rewards than this principle should one turn out in fact to belong to one of the more favored social classes. However, even if this is valid as a criticism of Rawls’s argument for the difference principle, it can be argued that Rawls’s thought experiment nevertheless provides strong intuitive support for those who believe that justice requires at least the enactment of a social minimum. For while most people placed behind the veil of ignorance might not be so risk averse as to choose the difference principle to govern their society, it is reasonable to suppose that most would at least be concerned to insure themselves against the danger of desperate poverty and would hence desire principles of justice that ensure everyone reasonable access to a social minimum. Interestingly, efforts by psychologists to model decision-making in situations akin to the original position show that people in practice tend to choose a principle that calls for the maximization of average well-being but subject to the constraint that nobody falls below a specified floor (see Frolich and Oppenheimer 1992).
