Prioritarianism

Prioritarianism or the priority view is a view within ethics and political philosophy that holds that the goodness of an outcome is a function of overall well-being across all individuals with extra weight given to worse-off individuals. Prioritarianism thus resembles utilitarianism. Indeed, like utilitarianism, prioritarianism is a form of aggregative consequentialism; however, it differs from utilitarianism in that it does not rank outcomes solely on the basis of overall well-being.

The term "prioritarianism" was coined by moral philosopher Larry Temkin in an effort to explicate the theory's non-egalitarian form. Richard Arneson, a proponent of the view, offers the following precise formulation:

Prioritarianism holds that the moral value of achieving a benefit for an individual (or avoiding a loss) is greater, the greater the size of the benefit as measured by a well-being scale, and greater, the lower the person's level of well-being over the course of her life apart from receipt of this benefit.

Like utilitarians, prioritarians believe in maximizing moral value or goodness, with the proviso that the latter consists in more than just overall well-being. Prioritarianism says that benefits to the worse off matter more than benefits to the better off.

To further sharpen the difference between utilitarianism and prioritarianism, imagine a two-person society: its only members are Jim and Pam. Jim has an extremely high level of well-being, is rich, and lives a blissed-out existence. Pam, by contrast, has an extremely low level of well-being, is in extreme poverty, living a hellish existence. Now imagine that we have some free resources (say, $10,000) that we may distribute to the members of this society as we see fit. Under normal circumstances, due to the diminishing marginal utility of money, the $10,000 will generate more well-being for Pam than it will for Jim.

Thus, under normal circumstances, a utilitarian would recommend giving the resources to Pam. However, imagine that Jim, for whatever reason, although already filthy rich and very well-off, would gain just as much well-being by receiving the $10,000 as would Pam. Now, since it makes no difference in terms of overall well-being who gets the $10,000, utilitarians would say it makes no difference at all who gets the $10,000. Prioritarians, by contrast, would say that it is better to benefit Pam, the worse off individual.
