Rational Preferences: A Flawed Assumption

The effectiveness of preference utilitarianism hinges on the rationality of preferences, raising the question of whether irrational or misinformed choices should be prioritized. Considerations include preferences from individuals in poor mental health, those acting out of anger, or historical preferences that might no longer hold relevance. Recognizing that preferences may not always reflect rational decision-making challenges the core principles of preference utilitarianism. This oversight suggests that when preferences are required to be rational to be valid, they may inadvertently align with a broader definition of maximizing well-being and minimizing suffering.
