Most of us want to make a difference. We see suffering injustice and death and are moved to do something about them. But doing good is hard, and it’s easy to be disheartened by the challenge. We help students and young professionals maximize the good they can do with their careers. To do this, we use high-quality evidence and careful reasoning to work out how to help others as much as possible and nurture a community of people who act on the insights gained.
