Negative utilitarianism is a form of negative consequentialism that can be described as the view that people should minimize the total amount of aggregate suffering, or that they should minimize suffering and then, secondarily, maximize the total amount of happiness. It can be considered as a version of utilitarianism that gives greater priority to reducing suffering (negative utility or 'disutility') than to increasing pleasure (positive utility). This differs from classical utilitarianism, which does not claim that reducing suffering is intrinsically more important than increasing happiness. Both versions of utilitarianism hold that morally right and morally wrong actions depend solely on the consequences for overall aggregate well-being. 'Well-being' refers to the state of the individual. Negative utilitarianism would thus differ from other consequentialist views, such as negative prioritarianism or negative consequentialist egalitarianism. While these other theories would also support minimizing suffering, they would give special weight to reducing the suffering of those who are in the worse position. The term 'negative utilitarianism' is used by some authors to denote the theory that reducing negative well-being is the only thing that ultimately matters morally. Others distinguish between 'strong' and 'weak' versions of negative utilitarianism, where strong versions are only concerned with reducing negative well-being, and weak versions say that both positive and negative well-being matter but that negative well-being matters more. Other versions of negative utilitarianism differ in how much weight they give to negative well-being ('disutility') compared to positive well-being (positive utility), as well as the different conceptions of what well-being (utility) is. For example, negative preference utilitarianism says that the well-being in an outcome depends on frustrated preferences. Negative hedonistic utilitarianism thinks of well-being in terms of pleasant and unpleasant experiences.
