This presentation explores the question of how can we do the most good to address suffering and improve flourishing throughout the globe. This is not an easy question to answer, as there are many specific actions we can take to do so. The presentation thus considers the underlying principles behind what we mean by "doing good," and how we can use rational thinking to quantify the amount of good we do in the world. From that basis, it proceeds to consider the kind of paths we can take that would maximize the good we can do. It then examines what other people committed to applying rational thinking to doing good have done as part of the Effective Altruism movement. Finally, it considers specific actions that each of us can take to bring our inherently limited resources to bear on addressing global suffering and improving global flourishing.
