“Rationality is about optimal goal achievement. Whatever your goals are, you’re rational if you act so as to maximize their expected achievement, i.e. so as to maximize your life-game EV. [I argue] that if people were more rational – reasoned better about what their life goals actually are and how to optimally achieve them – they would likely donate much greater amounts to charity than they currently do.”

— Adriano Mannino, Saving lives through donation: A rational choice (2014)
