Where does utilitarianism work the best?

Utilitarianism works best in situations where decisions can be made based on measurable outcomes and collective well-being, such as in public policy and healthcare. It is effective in assessing the consequences of actions to maximize overall happiness or minimize suffering, allowing for pragmatic solutions to societal issues. Additionally, utilitarian principles can guide ethical dilemmas in business and environmental decision-making by focusing on the greatest good for the greatest number. However, it may struggle in contexts where individual rights and justice are at stake.
