The utility monster is a thought experiment in the study of ethics. It was created by philosopher Robert Nozick in
1974 as a criticism of utilitarianism.
In the thought experiment, a hypothetical being is proposed who receives as much or more utility from each additional
unit of a resource he consumes as the first unit he consumes. In other words, the utility monster is not subject
to diminishing marginal returnswith regard to utility, but instead experiences constant marginal returns, or even
increasing marginal returns.
Since ordinary people receive less utility with each additional unit consumed, if the utility monster existed, the
doctrine of utilitarianism would justify the mistreatment and perhaps annihilation of everyone else, according to
Nozick's argument.
In his words:
Utilitarian theory is embarrassed by the possibility of utility monsters who get enormously greater sums of utility
from any sacrifice of others than these others lose . . . the theory seems to require that we all be sacrificed in the
monster's maw, in order to increase total utility.[1]
This thought experiment attempts to show that utilitarianism is not actually egalitarian, even though it appears to be
at first glance.
Some ways of aggregating utility, such as based on Rawls' maximin or difference principle, can circumvent the
conclusion that all units should be given to the utility monster. In particular, maximin sets a group's utility as that of
the being with least utility. Thus, giving units to the utility monster fails to change the group's utility unless the utility
monster has the least utility. Even if the utility monster has the least utility, maximin would only prefer allocating
units to the monster until it catches up with the member that has next-to-least utility.

Social implications [edit source]
Capitalist economics [edit source]
The utility monster has been identified directly with capitalism, and particularly the neoliberaldoctrine that free market
relations are the best way to constitute society. The discipline ofeconomics is related because it identifies "utility" as
a quantity that can be optimized across human beings. According to critics, these ways of thinking produce
decisions that are selfish, shortsighted, and destructive to the many while benefiting the few.[2]
Population [edit source]
The utility monster has been invoked in debates about population. Derek Parfit's mere addition paradox suggests that
additional humans would add to total happiness, even if expanding population decreases average happiness.
Opposite reasoning yields the "repugnant conclusion" that the world would be better off with one extremely happy
person. Parfit suggests that Nozick's utility monster is unrealistic because one being could not experience more
utility than millions of other beings put together.[3]
